Description of the Invention: [Technical Field of the Invention] Field of the Invention The present invention relates to a display element having a plurality of display portions stacked thereon, a paper having the member element, an electronic terminal device having the electronic paper, and The display system of the electronic terminal device and the image processing method of the display element. [Jiu] Background Art In the past years, the development of electronic paper has been flourishing in various companies and universities. A multi-purpose application mobile machine such as an electronic book is used as an electronic book, and a sub-display of a mobile terminal device and a display unit of a 1C card have been proposed. The powerful display method of electronic paper, 1 has a nighttime ~ member element using a liquid crystal composition of the domain cholesterol phase (called cholesteric liquid crystal). Cholesterol liquid crystals have excellent characteristics such as semi-permanent display retention characteristics (memory), vivid color display characteristics, high contrast characteristics, and high resolution characteristics. Fig. 12 is a view schematically showing a cross-sectional structure of a liquid crystal display element 51 which can be displayed in full color using a cholesteric liquid crystal. The liquid crystal display element 51 has a structure in which a blue (B) display portion 46b, a green (G) display portion 46g, and a red (R) display portion 46r are laminated in this order. In the drawing, the side of the substrate 4 on the upper side is a display surface, and an external light source (solid arrow) is incident from the upper side of the substrate 47b toward the display surface. Further, the upper surface of the substrate 47b is patterned to indicate the observer's eye and its observation direction (dashed arrow). 5 200816133 The B display portion 46b has a blue (B) liquid crystal 43b sealed between the pair of upper and lower substrates 47b and 4%, and a pulse wave voltage source 41b capable of applying a predetermined pulse wave voltage to the B liquid crystal layer 43b. The G display portion 46g has a green (G) liquid crystal 43g sealed between the pair of upper and lower substrates 47g and 49g, and a pulse wave voltage source 41g capable of applying a predetermined pulse wave voltage to the G liquid crystal layer 43g. The R display portion 46r has a red (R) liquid crystal 43r sealed between the pair of upper and lower substrates 47r and 49r, and a pulse wave voltage source 41r capable of applying a predetermined pulse wave voltage to the r liquid crystal layer 43r. The light absorbing layer 45 is disposed on the back surface of the substrate 49r under the R display portion 46r. The cholesterol liquid 10 crystal system used for each of the B, G, and R liquid crystal layers 43b, 43g, and 43r has a large content of the additive (also referred to as palm material) of tens of weight % of palm-like property (also known as palmate). A liquid crystal mixture added to a torsional liquid crystal. Once the twisted liquid crystal contains a large amount of the palm material, a cholesterol phase which strongly twists the torsional liquid crystal molecules into a spiral shape can be formed. Cholesterol liquid crystals are also known as palmar torsion liquid crystals. 15 Cholesterol liquid crystal has double stability (memory), which can be in any state of parallel state, vertical spiral state or parallel spiral state mixed with vertical spiral state depending on the electric field strength applied to the liquid crystal. A parallel spiral state and a vertical spiral state are formed, and then the state is maintained even in the absence of an electric field. The parallel spiral state is obtained by applying a predetermined high voltage between the upper and lower substrates 47, 49 and applying a strong electric field to the liquid crystal layer 43, and then rapidly setting the electric field to zero. The vertical spiral state is obtained, for example, by applying a predetermined voltage lower than the above-described high voltage between the upper and lower substrates 47 and 49, and applying an electric field to the liquid crystal layer 43, and then rapidly setting the electric field to zero. The intermediate state in which the parallel spiral 6 200816133 state is mixed with the vertical spiral state is, for example, a voltage lower than a voltage at which a vertical spiral state can be obtained is applied between the upper and lower substrates 47, 49' and an electric field is applied to the liquid crystal layer 43. It is obtained by sharply setting the electric field to zero. 5 The display principle of the liquid crystal display element using this cholesteric liquid crystal is explained using the Fig. 13 and taking the B display portion 46b as an example. Fig. 13(a) shows the alignment state of the liquid crystal molecules 33 of the cholesteric liquid crystal in the parallel spiral state of the B liquid crystal layer 43b of the B display portion 46b. Fig. 13(b) shows the alignment state of the liquid crystal molecules 1033 of the cholesteric liquid crystal in the vertical spiral state of the liquid crystal layer 43b of the B display portion 46b. As shown in Fig. 13(a), the liquid crystal molecules 33 in the parallel spiral state are sequentially rotated in the thickness direction of the substrate to form a spiral structure, and the spiral axis of the spiral structure is approximately perpendicular to the substrate surface. In the parallel spiral state, light of a predetermined wavelength region corresponding to the helical pitch of the liquid crystal molecules is selectively inverted in the liquid crystal layer. If the average refractive index of the liquid crystal layer is η and the pitch of the spiral is Ρ, the maximum wavelength λ of the reflection can be expressed by ι = η · ρ. Therefore, when the blue light is selectively reflected in the parallel spiral state of the liquid crystal layer 43b in the Β display portion 46b, the average refractive index η and the pitch 疋 pitch ρ are determined so as to be, for example, λ = 48 〇 nm. The average refractive index η is adjusted by selecting the liquid crystal material and the 20 coffin, and the helical pitch ρ can be adjusted by adjusting the content of the palm material. On the other hand, as shown in Fig. 13(b), the liquid crystal molecules 3 in the vertical spiral state are sequentially rotated toward the inner surface of the substrate to form a spiral structure, and the spiral axis of the spiral structure is approximately parallel to the substrate surface. In the case of the vertical spiral state of 200816133, the liquid crystal layer 43b for B loses the selectivity of the reflection wavelength, and the incident light is almost completely transmitted. The transmitted light is absorbed by the light absorbing layer 45 disposed on the back surface of the substrate 49r under the R display portion 46r, so that dark (black) display can be realized. As described above, the cholesteric liquid crystal can control the reflection of light by the alignment state of the liquid crystal molecules 33 5 which are twisted into a spiral shape. Similarly to the liquid crystal layer 43b for b, the cholesteric liquid crystal 'selectively reflecting green or red light in a parallel spiral state is sealed in the liquid crystal layer 43g for G and the liquid crystal layer 43r for R, respectively. Liquid crystal display element 51. Fig. 14 shows an example of a reflection spectrum of each of the liquid crystal layers 43b, 43g, and 43r in a parallel spiral state. The horizontal axis represents the wavelength (nm) of the reflected light, and the vertical axis represents the reflectance (white plate ratio; %). The reflection spectrum of the liquid crystal layer 3b for B is shown by a curve connecting ▲ marks in the figure. Similarly, the reflection spectrum of the liquid crystal layer 3g for G is indicated by a curved line in the figure, and the reflection spectrum of the liquid crystal layer 3r for r is indicated by a curve connecting ♦ marks in the figure. As shown in Fig. 14, the center wavelength of the reflection spectrum of the parallel spiral state of each of the liquid crystal layers 43b, 43g, and 43r becomes longer in the order of B, G, and R. Therefore, the spiral pitch of the cholesteric liquid crystal is the liquid crystal layers 43b and 43g. The order of 43r becomes longer. As a result, the content of the palmitic material of the liquid crystal layers 43b, 43g, and 43r must be lower in the order of the liquid crystal layers 43b, 43g, and 43r. 20 In general, if the reflection wavelength is shorter, the liquid crystal molecules must be strongly twisted to shorten the spiral pitch, so that the content of the palm material in the cholesteric liquid crystal becomes high. Further, in general, the higher the content of the palm material, the higher the driving voltage tends to be. Further, the reflection band width Δ is increased as the refractive index anisotropy Δη of the cholesteric liquid crystal becomes larger. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 When the still picture is displayed, even if it is updated to a different picture, the problem of the so-called "burning" of the previous display image slightly remains. The reason for the burning is estimated to be 10 kinds of various factors such as moisture, ionic impurities or phase interaction between the liquid crystal and the substrate. In order to eliminate the burning, very high stability is required in the fine system and interface state of the material. Further, in order to prevent this burning, the liquid crystal display element is provided with a timer or a photo sensor, and the full screen is set by detecting that the continuous operation time or the liquid crystal display element is placed in a dark environment. In standby mode (turn off display) to prevent burning. However, in the case where these methods take time from the standby state to the restoration (redisplay), there is a problem that the convenience of the liquid crystal display element is remarkably lowered in the case where it is urgent to look at the display image. Patent Document 1 discloses that the higher the ambient temperature, the stronger the burning phenomenon occurs. Therefore, when the temperature sensor detects a predetermined temperature or higher, the example 20 shows that the full-faced all-black anti-burning pattern is displayed. The liquid crystal is placed in a vertical spiral state, thereby preventing the method of burning. However, once the burn-in prevention pattern is displayed on the display screen, the image displayed so far is temporarily erased. As a result, there is a problem that the convenience of the liquid crystal display element is remarkably lowered. 9 200816133 Patent Document 2 discloses a method of dividing a common electrode at each stage and reducing power consumption in a monochrome display of seven stages. Further, Patent Document 2 discloses a technique for initializing a display element to prevent burning. However, Patent Document 2 only discloses a monochrome display of 7 segments, and the technical idea of the dot device type display device of the color display is irrelevant.

Layer 3b. The liquid crystal layer B for B has a cholesteric liquid crystal for B which has been adjusted to have an average refractive index n and a pitch p of p to selectively reflect blue. The G display portion 6g has a liquid crystal layer 3g for G which is disposed between the two substrates 7g and 9g by one of the pair of upper and lower substrates %, 9 §, and 17 200816133. The G liquid crystal layer 3g has a cholesteric liquid crystal for G, and the G cholesteric liquid crystal has been adjusted to have an average refractive index n and a spiral pitch p for selectively reflecting green. The R display portion 6r has an R liquid crystal layer 3r that is disposed between the upper and lower substrates 7r, 9r, and 5, and is sealed between the two substrates 7r and 9r. The G liquid crystal layer 3i* has a chromic liquid crystal for R which has been adjusted to have an average refractive index and a spiral pitch p for selectively reflecting red. The liquid crystal composition constituting the liquid crystal layers 3b, 3g, and 3r for B, G, and R is a cholesteric liquid crystal in which a palm-shaped material is added in an amount of 1 Torr to 4 Å by weight to twist the liquid crystal. The addition ratio of the 10 palm-shaped material was a value when the total amount of the twisted liquid crystal component and the palm-shaped material was set to 100% by weight. Although various materials can be used as the torsion liquid crystal, the dielectric constant of the cholesteric liquid crystal composition is preferably 20$ Δ ε $50. If the dielectric variability Δ ε is added, the selection range of the palm-shaped material that can be used is widened. When the dielectric Δ Δ ε is lower than the above range, the driving voltage of each of the liquid crystal layers 3b, 3g, and 3r becomes high. On the other hand, when the dielectric anisotropy Δ £ is higher than the above range, the liquid crystal display element! The stability and reliability are reduced, and image defects or image distortion are liable to occur. The refractive index of the cholesteric liquid crystal is in the opposite direction, and the & Δη system dominates the image quality. The value of the refractive index anisotropy - preferably ο · Δ like 2 core - ^ refractive index anisotropy Δη is smaller than this range, the reflectivity of the layers 3b, 3g, 3r of each liquid in the parallel spiral state becomes lower Therefore, there is a lack of brightness: On the other hand, if the refractive index anisotropy Δη is larger than this range, the scattering reflection of the liquid crystal layers 3b, 3g, and 3r in the vertical spiral state becomes large, because 18 200816133 % 5 shows that the color purity and contrast of the surface are insufficient. And a fuzzy display is formed. Further, if the refractive index anisotropy Δ!! is larger than the above range, the viscosity is increased to lower the reaction rate of the cholesteric liquid crystal. The value of the resistivity 胆固醇 of the cholesteric liquid crystal is preferably 1010 ^ Ρ $ 1 〇 13 (Ω · cm). Further, since the viscosity of the cholesteric liquid crystal is low, the voltage rise at a low temperature and the decrease in contrast can be suppressed, so that it is preferable. • In the laminated structure of the display portions βΐ), 6g, and 6r of B, G, and R, the optical rotation of the liquid crystal layer 3g for G in the parallel spiral state and the optical rotation of the liquid crystal layers 3b and 3r for the B and R. Therefore, in the field where the reflection spectrums of blue and green, and green and red are shown in Fig. 14, for example, the liquid crystal layer 3b for B can reflect the light of the right circular polarization, and the liquid crystal layer 3g for G can make the left circle. Polarized light reflects. By this, the loss of reflected light can be reduced, and the brightness of the display surface of the liquid crystal display element 1 can be improved. 15 • The upper substrates 7b, 7g, and 7r and the lower substrates %, 9g, and 9r must have light transmissivity. In this embodiment, two glass substrates are used. Further, a film substrate such as polycarbonate (PC) or polyethylene terephthalate (PET) may be used instead of the glass substrate. In the present embodiment, the upper substrates 7b, 7g, 7r and the lower substrates 9b, 9g, and 9r are all translucent, but the substrate 91* disposed under the R display portion 6r of the lowermost layer may be opaque. . ^ 20 B B on the bottom surface of the substrate 9b below the B display portion 6b is formed with a plurality of strip-shaped data electrodes l9b extending in the upper and lower directions in the first drawing in parallel with the liquid crystal layer 3b side. Further, a plurality of strip-shaped data electrodes 17b extending in the left-right direction in the first drawing are formed side by side on the B liquid crystal layer 3b side of the upper substrate 7b. In the present embodiment, the transparent 19 200816133 electrode composed of indium tin oxide (ITO) is patterned to form a strip-shaped scan electrode 17b and a plurality of data electrodes 19b. The material for forming the two electrodes 17b and 19b can be represented by, for example, nr. Alternatively, a transparent conductive film such as indium zinc oxide (IZO) or a photoconductive film such as amorphous germanium can be used. As shown in Fig. 1, the electrode forming faces of the upper and lower substrates 7b and 9b are viewed in the normal direction, and the electrodes 17b and 19b are arranged to face each other in the opposite direction. The parent fork regions of the two electrodes i7b and 19b respectively constitute pixels (alloys). The plurality of pixels are arranged in a matrix shape by the two electrodes 17b and 19b to form a display pupil plane. Further, the numbers 17b and 19b shown in Fig. 2 indicate the existence areas of the two electrodes 17b and 19b, and 10 is not taught. The shape of the equal electrode. The functional film disposed on the two electrodes 17b and 19b is preferably coated with an insulating film or an alignment-stabilized film of liquid crystal molecules (all of which are not shown in the drawings). The insulating film has an electrode 17b, A short circuit between 19b and a function as a gas barrier layer can improve the reliability of the liquid crystal display element 1. Further, a 15 mercaptoethylamine resin, an acrylate resin or the like can be used as the alignment stabilizing film. For example on the electrodes 17b, 19b The respective substrates are integrally coated with an alignment stabilizing film. The alignment stabilizing film may also be an insulating film. The liquid crystal layer 3b for B is sealed by the sealing material 18b applied around the upper and lower substrates 7b and 9b. Between the substrates 7b and 9b, the thickness (cell pitch) of the liquid crystal layer 3b 20 for B must be kept uniform. In order to maintain a predetermined cell pitch, a spherical spacer made of resin or inorganic oxide is used. The columnar spacers which are interposed in the liquid crystal layer 3b for B or which are coated with a thermoplastic resin are formed in a plurality of liquid crystal layers 3b for B. In the present embodiment, the liquid crystal display unit 1 is used for B. A spherical spacer (not shown) 20 200816133 is also inserted into the liquid crystal layer 3b to maintain the uniformity of the cell pitch. The cell pitch d of the liquid crystal layer 3b for B is preferably in the range of G. Display portions 6g and R Since the display portion 6r has the same structure as the B display portion 6b, the description thereof will be omitted. The outer surface (back surface) 5 of the substrate 9r under the R display portion 6r is provided with the visible light absorbing layer 15. Therefore, the liquid crystals of all B, G, and R are provided. When the layers 3b, 3g, and 3r are in the vertical state of the circle, the liquid crystal display element 1 The display screen can display black. Further, the visible light absorbing layer 15 can be provided as necessary. The scan electrode driving circuit 20 for driving the scanning electrode driver 1C for individually driving the plurality of scanning electrodes 17b, 17g, and 171* is connected to the upper substrate 10 7b, 7g, and 7r. Further, a data electrode driving circuit 21 for driving the data electrode driver for individually driving the plurality of data electrodes 19b, 19g, and 19r is connected to the lower substrates 9b, 9g, and 9r. These driving circuits are constructed. The pulse-like scanning signal or data signal is output to the predetermined scanning electrodes 17b, 17g, nr or the material 15 electrodes 19b, 19g, 19r in accordance with a predetermined signal output from the display control circuit 29. The electronic paper is constructed by providing the input/output device and the overall control device (all not shown in the drawings) on the liquid crystal display element 1 shown in Fig. 1 . The electronic paper can be used as a display device for electronic terminals. The electronic terminal machine can be used as a display device of a display system. 20 Next, the driving method of the liquid crystal display element 1 will be described using Figs. 3 and 4. Fig. 3 shows an example of a driving waveform of driving data of the liquid crystal display element 1. Fig. 3(a) shows a driving waveform for driving the cholesteric liquid crystal to a parallel spiral state, and Fig. 3(b) shows a driving waveform for driving the cholesteric liquid crystal to a vertical spiral state. In Fig. 3(a) and Fig. 3(b), the upper table of the figure 21, 200816133 shows the shape from the data electrode_circuit 2(), and the middle part of the figure shows the wave m^ pole from the sweeping voltage waveform Vd. The waveform of the scanning signal private voltage outputted by the driving circuit 21 is not applied to the waveforms of the applied voltage Vic of any liquid crystals of B, G, and R. Further, in Figs. 3(8) and 3(b), the elapsed time is shown from the left to the right, and the voltage is indicated in the upper and lower directions. _ 10 Fig. 4 shows an example of voltage-reflectance characteristics of cholesteric liquid crystal. The horizontal axis indicates the value (V) of the pure-breasted sweater, and the reflectance (%) of the cholesterol liquid crystal is recorded vertically. The curve p of the solid line shown in Fig. 4 indicates the voltage-reflectance characteristic of the cholesteric liquid crystal in which the initial shape can be a parallel spiral state, and the curve of the dotted line is the voltage of the biliary liquid crystal in the vertical spiral state. Rate characteristics. An example is given to apply a predetermined voltage to the first! The display portion shown in the figure is still in the case of 15 blue (8) pixels (1) of the intersection of the data electrode 19b of the first column and the scanning electrode 17b of the third row. As shown in FIG. 3 (8), during about 1/2 of the first half of the selection period T1 of the scan electrode 17b of the i-th row, the data signal voltage Vd is +32 V, and the scan signal voltage is 〇乂, and During about 1/2 of the second half, with respect to the data signal voltage ¥ (1 is 〇¥, the scanning signal voltage Vs is +32V. Thus, the B pixel (1, B uses the liquid crystal layer 讣 in the 2 〇 selection period T1) A pulse wave voltage of ±32 V is applied between them. As shown in Fig. 4, once a predetermined high voltage VP100 (for example, 32 V) is applied to the cholesteric liquid crystal to generate a strong electric field, the spiral structure of the liquid crystal molecules is completely untwisted, and all the liquid crystals The knives form a vertical alignment state with the direction of the electric field. Therefore, the liquid crystal molecules of the liquid crystal layer 3b for B of the B pixel (1, 1) are in a state of vertical alignment 22 200816133 during the selection period. When the non-selection period D2 is reached, a voltage of, for example, +28 V and +4 V is applied to the scan electrode 17b of the first row in one cycle of the selection period T1. In contrast, a predetermined data signal voltage Vd is applied to the fifth column. Data electrode 19b. In Figure 3 (8), the selection period Between the two! / ^ cycle to the data electrode 17 of the first column, such as + 32 乂 and the voltage of the evaluation. Therefore, in the non-selection period between the two can be egg pixels (!, !) B with liquid crystal layer A pulse wave voltage of ±4 V is applied. According to the above, between the non-selection period T2, the electric field generated in the B pixel U and the liquid crystal layer % is about zero. 10 When the liquid crystal molecules are in the vertical alignment state, the liquid crystal voltage Vlc is applied.

And forming a parallel spiral state of light that selectively reflects its corresponding helical pitch. Therefore, since B 15 of the B pixel G, i) forms a parallel spiral state with the liquid crystal layer 3b, the light is reflected, so that the B pixel (1, 1) displays blue. On the other hand, as shown in Fig. 3(b), during the selection period, the period of about 1/2 of the first half and the period of about 1/2 of the second half are relative to the data signal voltage vd of 24V/8V. When the scanning signal voltage Vs is 0v/+32v, the pulse voltage of the earth 20 24V is applied to the liquid crystal layer of the B pixel (i, 丨). As shown in Fig. 4, once a predetermined low voltage VF! 〇〇b (e.g., 24v) is applied to the cholesteric liquid crystal to generate a weak electric field, the spiral structure of the liquid crystal molecules is in an uncompleted state. When the non-selection period T2 is reached, a voltage of 23 200816133 of, for example, + 28v / + 4V is applied to the scan electrode 17b of the first row by the work period of 2 cycles, and the predetermined data signal voltage vd (for example, + 24V/8V) is applied. The voltage is applied to the data electrode 19b at a period of 1/2 of the selection period T1. Therefore, the B pixel can be applied between the non-selection periods T2 (1, the pulse voltage of -4V/+4V is applied by the liquid crystal layer. Thereby, between the non-selection period and the B pixel (1, 5丨) The electric field generated by the liquid crystal layer 3b is substantially zero. In the state where the spiral structure of the liquid crystal molecules is not completely solved, if the voltage applied to the cholesteric liquid crystal is changed from VF1 oowuAV) to VF0 (±4 V) When the electric field is sharply changed to about zero, the spiral axis of the liquid crystal molecules is spiraled toward the parallel directions with respect to the two electrodes 17b and 19b, and 10 is a vertical spiral state in which incident light is transmitted. Therefore, the B liquid crystal layer 3b of the B pixel (1, 1) is in a vertical spiral state and transmits light. Further, as shown in Fig. 4, after applying a voltage of VP100 (±32 V) and generating a strong electric field in the liquid crystal layer, even if the electric field is gradually removed, the cholesteric liquid crystal can form a vertical spiral state. The driving voltage is an example. When a pulse-like voltage of 30 to 35 V is applied to the electrodes 17b and 19b for 2 〇ms at room temperature, the cholesteric liquid crystal of the B liquid crystal layer 3b is selectively reflected. (Parallel spiral state), if a pulse-like voltage of 15 to 22 V is applied for 2 μms in actual effect time, a good transmission state (vertical spiral state) is obtained. The green pixel and the pixels 〇 and u arranged corresponding to the B pixel (1, 1) are driven in the same manner as the driving of the B pixel (1, 1), and are stacked in three B, G, and R pixels. The pixels (1, 1) of (1, 1) are displayed in color. Further, the scanning electrodes 17b, 17g, and l7r from the first row to the eleventh row are subjected to so-called line sequential driving to rewrite the material voltage of each data electrode 1% in each row, so that the display data can be displayed. Output to the entire field of pixels (1, 1) to pixels (n, m) enables color display of 1 frame (display screen). Further, when the electric field of the intermediate intensity is imparted to the cholesteric liquid crystal and the electric field is sharply removed, the five gray scales which are mixed in the parallel spiral state and the vertical spiral state are displayed, and can be displayed in full color.

According to the image processing method of the display device configured in the present embodiment, it is possible to control scanning of the plurality of pixels on the first display portion and to rewrite the written image data to the first display portion. After the rewriting process, the second display unit is turned on by the second rewriting process. In this way, it is possible to construct a rewriting process of the display unit while keeping the visibility of the display element to a limit. Furthermore, the re-writing process of the present embodiment includes the reset processing of setting the displayed state of the pixel to a temporarily different display state in the same frame, and (4) after the reset processing, writing the image data to the human pixel. , in order to make the 20% of the displayed state of the same display state of the writer processing. In the case of the cholesteric liquid crystal, after the human processing towel is rewritten, after the resetting process of the vertical alignment state of the age II different from the time of the display, the image data is written to form the displayed state. The case where the visibility of the display element to be initialized can be reduced: sub-degree. Further, the following description will be referred to as a re-processing for the case where all the display=row rewrite processing of the display element is performed. ~ No (1) In the present embodiment, the reset processing is started in such a manner as to avoid the interval between the display portions. Thereby, when ', ', or after burning, the display element 25 200816133 can be effectively prevented from being burned to maintain a good display state. Next, the image processing method of the display element constructed in accordance with the present embodiment will be described by taking the liquid crystal display element 1 shown in Fig. 1 as an example. Fig. 5 is a flow chart 5 showing an image processing method of a display element constructed in accordance with the present embodiment. Fig. 6 is a view schematically showing the display unit 6 in the reprocessing process according to the image processing method of the display element constituted by the present embodiment. Fig. 6 is a view showing the display unit 6 before and after the start of the new process, and Fig. 6 (d) showing the display unit 6 at the end of the rewrite process, Fig. 6 (c) The display unit 106 indicates a state in which the rewriting process of 6 g is completed as the G of the first issuing unit. In Figs. 6(8) to 6(4), the diagram shown in the upper stage is a schematic representation of the π-彳 plane of the display port 6, and the diagram shown in the lower & shows the display image of the display unit 6. In the upper diagrams of FIGS. 6(8) to 6(d), the state in which the display portion reflects or transmits the incident light L indicates a normal display state, and the state in which the display portion does not reflect the pupil and transmits only the light indicates that the display is performed. The state of rewriting processing. 15 As shown in Fig. 6 (4), the pattern r painted with a red circle, the pattern g coated with a green triangle, and the pattern b coated with a square of blue are arranged in the upper half to be white and down. The display image in which the side half is a gray background is an example, and the image processing method of the component is shown. Furthermore, the graphic r is arranged in the field of the white background. The graphic g is arranged across the fields of the white and gray backgrounds, and the 20 images/b are arranged in the field of the gray background. In the present embodiment, the order of the display unit for rewriting processing is changed in accordance with the hue of the entire image, and 5 is used to achieve the visibility of the displayed image when the reset processing is performed. The overall color tone of the image can be judged according to the average value of the pixel value (the gray value of the gray I5) of the image data of the biliary image, or the image that has been displayed at the center of the sputum surface is extracted. Judging by images. The color of the entire display image is judged by the display control circuit 29. - According to the image processing method of the display element constructed in this embodiment, as shown in Fig. 5, first, it is judged whether or not the display image is monochrome (step is called. 5. The comparison is written in R, G, B in step S1. The respective video data of the pixels arranged in the display area of the display units 6r, 6g, and 6b are turned off to be monochrome as shown in FIG. 1 when the video (4) of each pixel corresponding to all the pixels is disposed on the side of each other. The pixels (i, 丨) are the same as the image data of the G pixels (the pixels 〇, 1) disposed directly below the B pixels (1, 1) (both are not shown in the figure), and the same applies hereinafter. When the image data of the B pixels (1, 2) to (n, m), the G pixels (1, 2) to (η, m), and the R pixels (1, 2) to (n, m) are the same, it is judged as Monochrome. This example shows a color display as shown in Fig. 6 (8), so it is judged to be non-monochrome display (No in step S1). Next, the color of the rewrite process is determined independently (step S4). S4, for example, the display control circuit 29 reads out each of the RGB image data from the image data memory 3, and then obtains a display for each RGB. The display control circuit 29 determines the color having the largest average value of the gray scale as the color closest to the entire display image. As shown in Fig. 6(a), the graph g ratio of this example is shown. The other graphics r and graphics|3 are large, so the average value of the grayscale data of the green 20 is larger than the other colors. Thus, the display control circuit 29 determines that the color tone of the display image is green. Next, as shown in FIG. Among the r, g, and B display portions 6r, 6g, and 6b, the display portion that reflects the hue color closest to the display image is subjected to rewrite processing at a timing independent of the other display portions (step S5). 27 200816133 The G display unit as the first display unit starts the rewrite process at an independent timing. In this way, the display control unit 29 can perform control so as to shift the R and B display portions 6r and 6b to start the operation. The rewriting process of the display unit 6g. Here, the driving method of the liquid crystal display device 1 at the time of the rewriting process will be described using Figs. 7 to 9. Fig. 7 to Fig. 9 show the case of rewriting in the case of rewriting the picture. The way to reset the display surface is still low. An embodiment of the driving method capable of resetting the display screen. In the present embodiment, the resetting process in the rewriting process sequentially resets the liquid crystal into a vertical alignment state or a vertical spiral state in a number line. As shown in Fig. 7, for example, the reset processing is performed every four lines, and the operation of writing data for one line at the same time is repeated by a number of lines and the surface is rewritten to enable low power consumption. The rewriting process of the display unit 6. Fig. 8 is a view showing the % voltage of each element applied to one scanning electrode 17 at the time of screen rewriting. Positive and negative AC pulse waves are applied to each pixel at a time. In the reset period shown in FIG. 8, the liquid crystal 'applies, for example, four times to reset the pulse, and the '', and applies a write voltage in the writing section across the rest interval. By using this reset driving method, the rewriting process can be ordered with low power consumption and high speed. Further, it is possible to use the write data itself for the reset processing without using, for example, a special reset data in which all the pixels are set to white. 2〇 In the seventh figure, the lower half of the screen indicates the screen for the previous display of the weight, and the upper half indicates the new display panel. The common mode described in Fig. 7 sequentially selects the line sequential scanning mode of the scanning electrode 17, and the segment mode selects a mode for applying a voltage to each of the grazing electrodes 19. The scanning side driver sequentially selects the scanning electrode (scanning line) and outputs the ON scanning pulse wave, and the data electrode side drive 28 200816133 is deactivated and outputs the pulse data of the 〇N data or the 〇 ff data according to the data to be displayed. In the case shown, it is indicated that the writing line is written from the uppermost scanning line, and the writing line of one line of the line is up to the vicinity of the center of the pupil surface, and the data is written on the line. In the processing, for example, the state in which the write data is reset is performed on the four lines. Use Figure 9 to proceed with this step. As shown in Fig. 9, first, four lines are set as the operation of the reset line. In Fig. 9, once the Eio signal of the scanning start signal on the scanning side and the Lp signal of the timing of shifting the data side and the shifting of the scanning side are simultaneously input 10, first from the screen in Fig. 7 The first line is selected above, and constitutes a state in which the poor material can be written to the line. Then, when two pulses such as the Eio signal and the Lp signal are simultaneously input, the first selected line is shifted by the Lp signal to select the second line, and the second line is simultaneously selected according to the simultaneously input E〇 signal. The 1 line ' constitutes a state in which two lines such as the first line and the second line are selected. By repeating this operation, in the reset line setting section, the first line to the fourth line are in a selected state', and a state in which data can be written into the four lines is formed. Only the Lp signal is input in the long-term rest line setting section ‘, and the 1-line shift is performed in accordance with the pulse wave, and the state in which the second line to the fifth line are selected is formed. 2〇 At the beginning of the next write interval, the Eio signal and the Lp signal are simultaneously input, and the second line to the fifth line selected from the previous line are shifted by one line per line. As a result, the third line to the sixth line are selected, and the first line on the screen, that is, the first line is also selected by the input of the Eio signal. In this state, the data of the first line can be written, and the data to be written can be written in the first line, and 29 200816133 is given the data for resetting the data of the first line from the third line to the sixth line. The resetting of the previously displayed data is performed. At this time, the second line is the rest line set in the rest line setting area, and data is not written. Corresponding to the input of the next Lp pulse wave, the previously selected line is shifted, and 5 is selected from the 2nd line and the 4th line to the 7th line. By adding the data of the second line in this state, the data to be written can be written on the second line, and the data to be displayed from the fourth line to the seventh line can be displayed. Further, based on the input of the next Lp pulse wave, the writing of the data of the third line from the second line and the fifth line to the eighth line is similarly selected. In the third line, the data of the first line has been written when the Lp pulse before the second time is rounded. However, in general, the reaction time of the cholesteric liquid crystal differs depending on the physical properties of the material, and is in the range of several tens of ms. At the input of the Lp pulse as the data write timing of the second line, the third line is a pause interval. In this interval (for example, 50 ms or less), the pixels of the third line are in a vertical spiral state or are shifted toward a parallel spiral state. The transition state of the middle 15 is determined, and when the third line data is actually assigned, any one of the vertical spiral state or the parallel spiral state is determined as the actual write state. Such an action is repeated, for example, to the 240th line, that is, the writing of the data to the line on the lowermost side of the writing is repeated. Lines 5 through 8 of the reset interval are synchronized with the third line of the write line. Therefore, the 20th to the 8th line is a mixture of pixels in the vertical alignment state and pixels in the vertical spiral dimension. Thus, on the 5th to 8th lines, light passes through the liquid crystal layer to display the color (e.g., black) of the light absorbing layer. In this reset section, the state in which the liquid crystal molecules are shifted from the state in which the image data have been written to the state of the vertical alignment has been unwrapped. Then, after the rest interval is in the writing section, it is 30 200816133 : the image data is written again, and a predetermined liquid crystal is applied to the liquid crystal layer to apply the above-mentioned resetting_News compared with the fourth_chemical method. In the case, since the liquid crystal molecules are first set to the vertical alignment state 5, the liquid crystal layer can be set to a good vertical spiral state. For example, the night crystal display element 1 can obtain an excellent contrast ratio.

In the case of the above-mentioned reset driving method, in the case of using 24 moving, for example, the data electrode is formed to open the image, and the image is transferred from the vertical (four) state to the vertical screw. FIG. 6 (8) shows that the above-described reset driving method is used. The processing unit 6 is written. The lower part of the diagram of Fig. 6(b) shows that the scanning electrode 17g is sequentially scanned from the main surface side of the G display portion 6g (refer to the old), and the screen is re-written at about -2 /3 (arrow and neck) Sg), using the reset drive method for the field. b includes, for example, six scanning electrodes for rewriting (4). The reset processing of the rewrite processing is executed in the reset section shown in Fig. 7, and the write processing of the rewrite processing is executed in the write section shown in Fig. 7. The display control unit 29 controls the scan electrode driving circuit 20 and the data electrode driving circuit 21 to rewrite the G display unit , so that voltage pulses applied at the same time are applied to a plurality of pixels of the G display unit 0g. The display control circuit 29 outputs, for example, the signals shown in Fig. 9 to the scan electrode driving circuit 2 and the data electrode driving circuit 21. Since the liquid crystal layer subjected to the re-writing process is formed in a vertical alignment state or a vertical spiral state, the field α of the G display portion 6g as the second display portion is in a state of transmitting the light L. It shifts to the state in which the light L is transmitted through the state of the light. On the other hand, as the second and _ 10 15 20 (d), the display 6 6b maintains the normal state of the reflected or transmitted light l. Thereby, as shown in the sixth paragraph, the liquid crystal display element is green - the scanning electrode 17bjL which is processed by the person is displayed in black, and the other image g which is the one color of the color is displayed, and the same red pattern as the normal display The image b of the ΓΓ7ίΓΓ shape and the scanning electrode subjected to the rewriting process are magenta in the middle gray scale, and the others display the same background of the gray image as the normal display. In this way, the liquid crystal display private ice is re-written to display the display screen of the sweeping money, which can maintain the full display and the usual color, the same color; it# display the image data from time to time.

Then, as shown in FIG. 5, the rewriting process for the display portions 6r and 6b as the second and third display portions (step S5) 〇r, b for the display portion 6r, > The re-writing process is performed by the same reset driving method of the G display portion 6g. As shown in the lower part of Fig. 4 (4), the scanning power (4) and 17b (refer to the third) are sequentially scanned from the upper side of the R and B display objects and the screen of 6b to the screen Μ, and the rewriting processing is ended (arrow Sr, Sb), and shows a state in which, for example, six scanning electrodes n included in ϋ or α are rewritten by the reset driving method. The member control unit 29 controls the scan electrode driving circuit Μ and the data electrode driving circuit (4), and displays the R and B display miscellaneous and _ lines to write the human pulse so that the voltage waveform of the same waveform is applied to about 32 200816133 10 15 20 A plurality of pixels (a plurality of second and third pixels) of the R and B display portions 6r and 6b. The liquid crystal layer subjected to the reset processing of the rewriting process forms a vertical alignment state or a vertical spiral state. Therefore, as shown in the upper part of Fig. 6(d), the field α of the R and B display portions 6r and 6b forms a state in which the transmitted light L is formed. On the other hand, the G display unit 6g maintains the normal display state of the reflected or transmitted light L. As a result, as shown in the lower part of FIG. 6(d), the liquid crystal display element 1 is subjected to the same red pattern as the normal display and a green triangle pattern g, and the scanning electrode 17 subjected to the rewriting process. 171^ is a black and other areas of the quadrilateral pattern b, and the scanning electrodes 17r, 17b performing the rewriting process are green of the intermediate gray scale, and the others are the same white or gray background as the normal display. . As shown in the lower part of Fig. 6 (4), the liquid crystal display element i can be maintained on the R and B display portions & the scanning lines 171· and 17b at the rewriting process. Display the display of different colors (4) of the usual display. As described above, by using the reset driving method shown in FIGS. 7 to 9 , for example, pixels of the plurality of scanning electrodes 17r and (7) arranged in the first row to the sunny state are sequentially scanned (the second and third of the plurality) After the pixel, the rewriting process as the R and _ portions 6P of the second and third display (four) is completed, and the renewing process of the display unit 6 is ended. = The overall color tone of the image is assumed to be green, and the case where the color is blue is 于 于 步骤 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 作为 Β Β Β Β Β Β Β Β Β Β &, then, in step 5, the rewriting process for the R and G display portions 6r and 6g which are the under-colors of the second and _th portions is performed. In the case where the color tone is red, the display unit 6b as the first display unit is erroneously reflected in the R and b display units 6r and 6b of the other colors to start the rewriting process. Next, in step S5, the R and G display portions 6r and 6g which are the reflection residual colors of the second and third display portions are rewritten. 5 In the present embodiment, as shown in the lower part of FIGS. 6(8) to 6(d), the rewriting process of the R and B display portions 6r and 6b is performed by rewriting the frame of the G display portion 6g. The process starts after the process is completed. However, as shown in the lower part of Fig. 6(b), the display image at the time of rewriting processing is a part of all the faces except for the usual case. Therefore, if the 10 rewrite processes of the R, G, and B display sections 6r, 6g, and 6b are not synchronized, the rewriting processing of the R and b display sections 6r and 6b as the second and third display sections is performed. It is also possible to start before the end of the rewriting process of the 1 frame of the g display unit 6g as the second member. In this case, the field in which the display field is different from the usual one in the rewriting process is wider than the field shown in the lower part of Fig. 6(b), but since the domain 15 is narrow relative to the entire display field, It is possible to maintain a display that fully recognizes the degree of image information normally displayed. As shown in Fig. 5, if it is determined in step 81 that the monochrome display is performed (Y in step S1), the rewriting process as the G display portion 6g of the first display portion is performed (step S2). Green has the highest visibility among RGB and has the greatest influence on the eyes that view the display image. Therefore, the G display unit 6g is separately rewritten. Next, the R and B display portions 6r and 6b as the second and third display portions are rewritten (step S3). As a result, the rewriting process of the display unit 6 is completed at the same time as the rewriting process of the R and B display portions 6r and 6b is completed. The processes of steps S2 and S3 are the same as the processes of steps s5 and s6, respectively. Therefore, the process of re-writing processing is not limited to the order of step (4)/, for example, after the job. Processing step · 2 'after processing step lion processing steps 5

Further, the thick arrow shown in the figure indicates the range in which the degree of burnt Δγ of the burnt can be recognized. As shown in Fig. 10, for example, after the display unit 6 displays the black and white checkered pattern, the color of the screaming screen is not white or the intermediate gray scale 5 is displayed. In this case, regardless of whether the display screen is completely white or has a certain intermediate gray scale color, the black and white checkered pattern burned on the right side of the figure in Fig. 10 may remain on the display screen. The degree of burning of the display unit 6 can be evaluated by using ΔΥ as an index. ΔΥ can be calculated by displaying the brightness yw of the white field 及 and the brightness 1 〇 Yb ′ of the black field β among the black and white checkered patterns and by ΔYcYw — Yb. The stronger the burning of the display unit 6 is, the black area B will be blackened, so the Yb value will decrease and the difference between Yw and Yb will become larger. Therefore, it can be judged that the larger the ΔΥ value, the stronger the burning of the pixels. The ΔΥ is repeatedly calculated at predetermined time intervals, for example, from the next day to several days, and the graph shown in Fig. 11 can be obtained. Further, in the measurement of the reflectance, a spectroscopic measuring machine manufactured by Otsuka Electronics Co., Ltd. can be used. As shown in Fig. 11, the burning time of the pixel shows that the longer the Δ is, the more the aging is increased. As shown by the dotted line in the figure, generally ΔΥ^〇·5 (when the 白 value of the standard white plate is set to 1 )), it can be said that the burning of the display screen is such that it does not constitute an influence. Therefore, the allowable range 5 of pixel burning in this embodiment is again Δ YS 0.5. The characteristics of Δ γ for the display time differ depending on the liquid crystal material used and the like. In the present embodiment, if the same image is displayed for 13.5 hours, Δ Υ > 〇·5, the burnt phenomenon can be recognized on the display side. Therefore, in the present embodiment, the new processing is set to be performed in a 12-hour cycle for the purpose of ensuring a predetermined benefit for the burning of the pixels. As a result, the liquid crystal display element 1 36 200816133 Δγ can be controlled to be less than 〇·5, so that the display screen can be prevented from being burned and the display quality can be improved. If the reprocessing of the present embodiment is performed in a 24-hour period, ΔΥ exceeds 〇·5, so that the display screen is burned to deteriorate the display quality of the liquid crystal display element 1. 5 For example, the display control circuit 29 memorizes the time interval from which the reprocessing of the burn-in is started. When the time data output from the timer 27 exceeds the time interval, the display control circuit 29 starts the renewing of the display unit 6 shown in Fig. 5. After the re-processing of the R, g, and Β display units 6r, 6g, and 6b is completed, the display control circuit 29 resets the time data of the timer 27 and restarts 10 to compare the time data output from the timer 27 and start renewing. The time interval for processing. Further, the liquid crystal display element 1 is constructed so that the illuminance data output from the photo sensor 26 of the detecting unit 25 can be independently and spontaneously started to be newly processed in accordance with the above-described time interval. The display control circuit 29 starts the renewing of the display unit 6 shown in Fig. 5 when the 15 degree data output from the photo sensor 26 is lower than the predetermined threshold value. After the re-processing of the display unit 6 is completed, the display control circuit 29 starts comparing the illuminance data output from the photo sensor 26 with the gate root value at which the re-processing is started. In this way, the liquid crystal display element 1 has the photo sensor 26, and when the liquid crystal display element 1 is brought into a dark place and the writing 20 cannot be seen, even if the 12-hour period is reached, the display control circuit 29 The renewing of the display unit 6 can be started spontaneously. As a result, the burning of the pixels can be prevented and the convenience of the liquid crystal display element 1 can be improved. The threshold value for starting the re-processing is preset to, for example, 50 (1 χ). Since the liquid crystal display element 丨 is a reflective display element', once the ambient illuminance is below 50 (1 χ), the recognition 37 200816133 degree is significantly lowered. Therefore, the rational indicators. (ΐχ)..., degree is suitable as a spontaneous renewed place. As explained above, according to this embodiment, the liquid crystal display element 1

In this case, the same voltage is applied to each of the scanning electrodes 17b, 17g, and 17r of the ruler and the q B display portions 6r, 6g, and 6r. However, by adjusting the voltage applied to the data electrode so that the voltage applied to the liquid crystal layer of the display portion which is not subjected to the re-writing process is approximately 〇V, 20 is obtained in the same manner as in the first and second embodiments described above.
