Embodiment
Below, with reference to the accompanying drawings, the preferred embodiments of the present invention are described.It should be understood that and the invention is not restricted to following preferred embodiment.
With reference to Fig. 1 and 2, the display device 100 according to this preferred embodiment has been described.Fig. 1 is a block diagram that schematically shows display device 100.Fig. 2 is a sketch, schematically shows the mode of display device 100 display message.
As shown in Figure 1, display device 100 preferably includes the display panel 10 of a display message, and the driving circuit 20 that drives display panel 10.Display device 100 preferably is used to be installed in a display device of the instrument panel in the automotive vehicle, but the present invention never is limited to this.Display device 100 can show various information, comprises driving the automotive vehicle information necessary.Although Fig. 2 has represented an exemplary situation, shown the speed (left side at Fig. 2 is represented) of automotive vehicle and the revolution (right side at Fig. 2 is represented) of engine, be understandable that display message is not limited thereto.Alternately, can show residual fuel amount, water temperature, remaining power energy, change lever position and/or any other relevant or material information.Although Fig. 2 has represented the image of a demonstration, be similar to the analogue instrument that each has index dial and pointer, display image alternately is the form of digital instrument, on digital instrument, the digit that expression in time changes.
For example, display panel 10 can be the display panels that for example comprises liquid crystal layer, comprise the organic EL display panel of organic electroluminescent device or comprise the inorganic EL display panel of inorganic el element.Can use any known various types of display panels.
The information that shows on display panel 10 comprises static information that shows and the information that dynamically shows.In the exemplary cases of Fig. 2, dynamically shown the part of the pointer that is similar to analogue instrument, and comprised the preferably expression statically of background parts of the part that is similar to index dial.
Traditional display device has a problem, and the picture point of any part that shows corresponding to static state continues to show with same brightness, and is irrelevant with the passage that shows the time, thereby causes aging (burn-in) of image.
The driving circuit 20 that display device 100 of the present invention comprises can change the Show Color of the static information that shows on display panel 10 with the passage that shows the time.Owing to changed Show Color, also change corresponding to the brightness of each picture point of R, G and B.As a result, the display device 100 of various preferred embodiments of the present invention has prevented the aging of image.Thereby the display device 100 of various preferred embodiments of the present invention prevents image aging based on the variation of Show Color, and need not change the display position of information with the passage that shows the time.This has prevented user's dispersion attention and puzzlement, has avoided delay that the above-mentioned relevant information of utilizing TOHKEMY 2003-177715 number disclosed technology and producing transmits or unsuccessful.
As employed in this explanation, " static state " mode of demonstration must not refer to absolutely not situation about overriding (as print, on the hard copy material), but comprise any situation that in certain period, does not override at least to feature.More particularly, " static state " mode of demonstration refers to the covering that does not show in the long like this time, if so that do not change Show Color, the situation of (as about 10 minutes or longer) may take place the aging of image.
Fig. 4 has represented the typical change of Show Color.In example shown in Figure 4, for example, the Show Color the during beginning of demonstration is, background is blue, and index dial is yellow, and pointer is red.But with the passage that shows the time, the change color of static background that shows and index dial is respectively to orange from the blueness to the green with from yellow.Along with the time further increases, green and orangely further be changed to different colors respectively.Simultaneously, dynamically pointer displayed preferably keeps red, and irrelevant with the demonstration time.
Preferably, any variation of the Show Color of static display message does not only take place in the driver can not produce puzzled or distractive scope owing to change color.
For example, preferably between the color of nearer each other color (tone), carry out the change of any Show Color.Fig. 5 represents a color dish, and representative is with round-robin position change color.By allowing Show Color to change between the color on the color dish, near (as between contiguous color), puzzling and taking sb's mind off sth of observer will be minimized these colors as much as possible.In addition, change with in the cocycle of color dish, can reduce observer's puzzlement and dispersion attention by allowing Show Color.
Further, preferably allow Show Color to gradually change or change continuously.For example, under the situation that changes Show Color between the contiguous color on the color dish shown in Fig. 5, the observer surpassed about 30 seconds or longer one-period in realize color change will can not produce puzzled or take sb's mind off sth.
Foregoing description has illustrated the preferred embodiment based on the variation of the Show Color of color dish.Below, the preferred embodiment that Show Color changes will further be described from different angles with reference to figure 6.
Fig. 6 is an XY chromaticity diagram of XYZ colorimeter system.The tristimulus values X of XYZ colorimeter system, Y and Z represent with following equation:
X=2.7689R+1.7517G+1.1302B;
Y=R+4.5907G+0.0601B; And
Z=0.0565G+5.5943B。
Here, R, G, B are the tristimulus values of RGB colorimeter system, and each representative is corresponding to the quantity of stimulus of the cone cell reception of red (R), green (G), blue (B) coloured light human brain.
Can find out that from Fig. 6 and above-mentioned equation values X depends primarily on red values R, values Y depends primarily on green values G, and values Z depends primarily on blue values B.On the other hand, values X also comprises green values G and blue values B, and values Y also comprises red values R and blue values B, and values Z also comprises green values G.Therefore, under the situation that the brightness of the picture point of a given color is lowered, the brightness of the picture point that the variation of values X, Y, Z can be by increasing other color is reduced, and thus, observer's puzzlement and dispersion attention is minimized.For example, under the situation that the brightness (corresponding to redness) of R picture point is lowered, owing to the brightness of R picture point reduces tristimulus values X, the Y that takes place, the variation of Z can reduce to a certain extent by the brightness that increases G picture point and B picture point, thereby eliminate and puzzled and dispersion attention.
The variation of Show Color can realize by the brightness that only changes one of R picture point, G picture point, B picture point simply.But from eliminating the above-mentioned angle of puzzled and dispersion attention, preferably the variation that changes caused tristimulus values X, Y, Z by the brightness of one of R picture point, G picture point, B picture point compensates by the brightness that also changes two other picture point.
Below, with reference to figure 7A, 7B and 7C, the brightness of describing each pixel when Show Color changes is changed.
At first, under the constant traditional situation of the Show Color of static display message, shown in Fig. 7 A, the brightness of R picture point, G picture point and B picture point is time to time change not.
On the other hand, display device 100 according to the preferred embodiment of the invention, and the Show Color of static display message changes with the passing of time.Therefore, shown in Fig. 7 B, the brightness of R, G and B picture point also changes with the passing of time.
Fig. 7 B represents to realize gradually changing of Show Color, and the brightness of picture point situation about also gradually changing separately.Fig. 7 C represents to realize the discontinuous variation of Show Color and the situation of the discontinuous variation of brightness of picture point separately.
From the relevant difficult minimized angle of the variation that makes Show Color, preferably realize gradually changing of Show Color, shown in Fig. 7 B.Angle from the variation of being convenient to control Show Color preferably realizes the discontinuous variation of Show Color, shown in Fig. 7 C.
Fig. 7 A, 7B, the synoptic diagram of 7C be the purpose in order to illustrate that the brightness of picture point separately changes just.Be understandable that the meaning on the absolute value of the brightness of R, G and B picture point self does not possess skills is as the result of the brightness addition of R shown in this article, G, B picture point and the meaning of definite special color on not possessing skills.
As shown in Figure 4, although top description has illustrated the indeclinable example of color of dynamic display information (being pointer), still can change the color of any dynamic display information with the passage that shows the time.
The variation of Show Color can be by providing a predetermined drive signal to realize from driving circuit 20 to display panel 10.In traditional display device, the same level of shows signal is retained in the picture point in any zone of the viewing area that shows still image.On the contrary, in the display device 100 of the preferred embodiment of the present invention, the level of the shows signal that the picture point in the zone of demonstration still image keeps changes with the passing of time.In other words, the variation of Show Color can realize that this voltage is to be provided to R picture point, G picture point and B picture point from driving circuit 20 by changing shows signal voltage.
With reference to figure 8, will a specific typical structure of the driving circuit 20 of realizing such driving be described.For example, driving circuit 20 (Fig. 1) can comprise a scan line drive circuit, and a signal-line driving circuit and a control circuit (timing generator) are used to control these circuit, and a signal processing 30 as shown in Figure 8.
Signal processing 30 preferably includes a static display-memory 31 that is used to be stored in the static information that shows on the display panel 10, be used to be stored in a dynamic display memory 32 of dynamic display information on the display panel 10, be used to change a color conversion part 33 of the Show Color of the static information that shows on display panel 10, and a composite part 34 that is used to merge static display message and dynamic display information.
Except being input to the information of signal processing 30, the static any information that shows can be sent out and store into static display-memory 31, and the information of any dynamic demonstration can be sent out and store into dynamic display memory 32.The information that has stored static display-memory 31 into is sent to color conversion part 33, changes the Show Color of information there.For example, color conversion part 33 can be a tone conversion portion that changes the tone of Show Color.Therefore, static information that shows and the information that dynamically shows can be merged by composite part 34, and output to the drive part (as above-mentioned timing generator) in another control system and the driving circuit 20.
Utilize above-mentioned signal processing 30, can change the Show Color of static display message.Although Fig. 8 has represented the color conversion part 33 of insertion between static display-memory 31 and composite part 34, also can before static display-memory 31 color conversion part 33 be set, the information of having carried out color change by color conversion part 33 is stored in the static display-memory 31 then like this.Signal processing 30 can be integrally formed with any other parts in the driving circuit 20, or as independently element formation.
Although Fig. 3 has represented a structure, wherein each pixel preferably is made up of 3 picture points (R picture point, G picture point, B picture point), and dot structure is not limited thereto.For example, as shown in Figure 9, each pixel can be made up of 6 picture points (2 R picture points, 2 G picture points, 2 B picture points).Under the situation of carrying out monochrome demonstration (that is, only utilizing the relevant picture point that belongs to single color) with such dot structure, be that 2 R picture point R1 and R2 will be used for redness basically; 2 G picture point G1 and G2 will be used for green; 2 B picture point B1 and B2 will be used for blueness.Therefore, when changing Show Color in monochrome shows, the variation that is changed the brightness that any variation of the values that causes can be by another picture point (as another R picture point R2) by the brightness of one of two relevant picture points of set color (as a R picture point R1) compensates; And the unnecessary picture point that comprises any other color.
In addition, in accordance with a preferred embodiment of the present invention, in a display device, can carry out so-called spatial jitter (spatial dithering) process.Figure 10 is the sketch that a dot structure of spatial jitter process is carried out in expression.In structure shown in Figure 10, a pixel is divided into 4 sub-pixels, and each sub-pixel comprises a R picture point, a G picture point and a B picture point.The spatial jitter process is a technology of expressing with the gray level of space (zone) mode, and the summation of the gray scale level of wherein a plurality of (for example, 4) sub-pixel has defined the gray scale level of whole single pixel.Therefore, by utilizing the spatial jitter process, make increase (as 4 times increase) become possibility with the quantity of single pixel gray-scale displayed level level.
In the structure of permission spatial jitter process shown in Figure 10, when when preventing that image aging from changing Show Color, can change to compensate by any variation of the caused values of variation of the set sub-pixel brightness in the single pixel by the brightness that realizes another sub-pixel.For example, the brightness that changes the R picture point that the variation of caused values can be by another sub-pixel by the brightness of the R picture point of a set sub-pixel changes and compensates.Therefore, the brightness of each picture point can change greater than the amount in the following situation, and this situation is that to change the variation that causes values by the brightness of the picture point of a set color be that the brightness of the picture point by another kind of color changes and compensates.As a result, this provides the anti-aging effect that strengthens.Note that the compensation technique that the above-mentioned technology of the compensation that values changes on " between the sub-pixel " basis also can change with the values in each sub-pixel combines.
In structure shown in Figure 10, the R picture point that comprises in the pixel with the static mode display message, G picture point and B picture point gray-scale displayed level level are switched between sub-pixel with the passage that shows the time.Thereby the brightness that makes picture point changes and the Show Color that do not change whole single pixel becomes possibility.In this case, can prevent the aging of image, and not cause puzzling or taking sb's mind off sth of observer.
Although Figure 10 represented a pixel and comprised the example of four sub-pixels, carry out the spatial jitter process and do not need each pixel to comprise four or more sub-pixel.For example, also executable space dither process in dot structure shown in Figure 9.Particularly, a sub-pixel can be by R picture point R1, and G picture point G1 and B picture point B1 define, and another sub-pixel can be by other R picture point R2, and G picture point G2 and B picture point B2 define, but thereby has increased the quantity of the display gray scale level of twice quantity.In addition, the variation that changes the values that causes by the brightness of a sub-pixel can change by the brightness of another sub-pixel and compensates.Even, become possibility by between these sub-pixels, switching gray-scale displayed level level, make the Show Color that prevents image aging and do not change whole pixel.
