When reality was implemented, above-mentioned color lump can be optical filter or fluorescent powder is processed.In the present invention, except the foregoing description that the colour element layer is carried out, all belong to known technology, be not described in detail about other aspects of colour element layer.
In the present invention; Colour element layer 16 can adopt the mode of printing or being coated on the base layer to make; First, second conductive electrode layer 14,15 can adopt sputter to make in the lip-deep mode of equivalent layer, and mixolimnion 13 can adopt the mode of recording interlayer or the mode of coating to make.
To adopt RGBW type colour element layer 16 and colour element layer 16 to be arranged on the present invention on mixolimnion 13 1 side surfaces of first base layer 11 the image displaying principle is described below.
According to image demonstration needs; Drive control device controls is applied to the voltage signal of each electrode on first conductive electrode layer 14 and second conductive electrode layer 15; Make the R of each colour developing in unit 161, G, B, the mixolimnion that the W color lump is corresponding respectively partly be rendered as vaporific lucifuge state or the bright state of full impregnated or other progressive states; Thereby R, G, B, W color lump in each colour developing unit 161 externally demonstrate corresponding color.Because the area of the colour developing unit 161 that R, G, B, W color lump are formed very little (area of colour developing unit is the area of pixel); Be micron order; 107 ± 5 μ m for example; Therefore, for a colour developing unit 161, the color that the color that the blend of colors that the R in this colour developing unit 161, G, B, W color lump show is respectively constituted together finally externally demonstrates for these colour developing unit 161 pairing pixels (being the actual color of seeing of beholder's ability).That is to say, make each pixel demonstrate required color through the color of controlling each colour developing unit 161 pairing 4 subpixels points 20, thereby make display demonstrate required colored show state.Wherein, The color that the W color lump is shown can be decided by the Show Color of other three R in its colour developing unit 161, place, G, B color lump, and the adjusting target of W color lump is to make the brightness and the colour purity of the pixel of its colour developing unit, place 161 correspondences reach an equilibrium point.
Be that example specifies with a pixel below:
If it is shown in red that this pixel needs; Then on the corresponding pairing row-column electrode of R color lump of this pixel, apply low-frequency high-voltage electric signal (the positive and negative bidirectional pulse about 100v, 50Hz for example; The voltage magnitude of the voltage waveform that the low-frequency high-voltage electric signal stack back that applies on the row-column electrode forms is greater than threshold voltage magnitude; Threshold voltage is for making the smectic liquid crystal molecule by driving the magnitude of voltage that arrangement form changes taken place; It is to confirm according to the composition of mixolimnion and thickness, is generally more than the 5V.); On the corresponding G of this pixel, the pairing row-column electrode of B color lump, all apply high-frequency and high-voltage electric signal (for example the positive and negative bidirectional pulse about 100v, 1kHz, the voltage magnitude of the voltage waveform that the high-frequency and high-voltage electric signal that applies on row-column electrode stack back forms is greater than threshold voltage magnitude).Smectic liquid crystal molecule in the mixolimnion part of this R color lump correspondence twists, and becomes out of order arrangement form.Smectic liquid crystal molecule in the mixolimnion part of this G color lump, B color lump correspondence becomes regularly arranged form.From the light 30 of first base layer, 11 1 side incidents via first base layer 11, colour element layer 16, first conductive electrode layer, 14 directive mixolimnions 13.In the corresponding mixolimnion part of R color lump; Like Fig. 9; Because each of smectic liquid crystal molecule is to diversity (promptly because the light of this mixolimnion part of incident is different through the long optical axis of each liquid crystal molecule, the anaclasis angle of each liquid crystal molecule is different, thereby the refractive index of each liquid crystal molecule is different); There is very big-difference in the ray refraction of each smectic liquid crystal molecule of incident; Promptly in the corresponding very thin mixolimnion part of this R color lump, optical index has produced violent variation, and light in the corresponding mixolimnion part of this R color lump strong scattering takes place; (mixolimnion that this R color lump is corresponding partly demonstrates vaporific lucifuge state to be seen as a kind of astigmatic effect on the macroscopic view; As acute-matte), (in this mixolimnion part, the light of other color lump of light directive of scattering is seldom at this R color lump of a large amount of directives of light of the corresponding mixolimnion part inscattering of this R color lump; The light that penetrates via second base layer 12 can not impact the color demonstration of colour element layer 16, and also very faint via the light of second base layer, 12 reflected backs.)。If the R color lump adopts optical filter to process, then the R color lump has the selective permeation function to ruddiness, thereby makes the R color lump externally demonstrate redness.If the R color lump adopts fluorescent powder to process, the light that then is mapped to the R color lump produces stimulated radiation, thereby makes the R color lump externally demonstrate redness.In the present invention, the mode of above-mentioned this Show Color has adopted scattered beam mode image-forming principle.In the corresponding mixolimnion part of G color lump; The long optical axis of regularly arranged smectic liquid crystal molecule is perpendicular to the plane of first, second conductive electrode layer 14,15; Thereby the ray refraction of each smectic liquid crystal molecule of incident does not produce acute variation, and light can freely see through the corresponding mixolimnion part of this G color lump (demonstrating the bright state of full impregnated on the mixolimnion part macroscopic view of this G color lump correspondence) and directly penetrate from second base layer 12; Because the display display image is to rely on surround lighting to realize; The light of vertical incidence first base layer 11 is seldom, and light is that oblique incidence is to viewing area 50, therefore mostly; The light that finally can see through the G color lump is seldom, and the G color lump externally is not shown as any color.In like manner; In the corresponding mixolimnion part of B color lump, the long optical axis of regularly arranged smectic liquid crystal molecule is perpendicular to the plane of first, second conductive electrode layer 14,15, thereby; The ray refraction of each smectic liquid crystal molecule of incident does not produce acute variation; Light can freely see through the corresponding mixolimnion part of this B color lump (demonstrating the bright state of full impregnated on the mixolimnion part macroscopic view of this B color lump correspondence) and directly penetrate from second base layer 12, because the display display image is to rely on surround lighting to realize, the light of vertical incidence first base layer 11 is seldom; Light is that oblique incidence is to viewing area 50 mostly; Therefore, the light that finally can see through the B color lump also is seldom, and the B color lump externally is not shown as any color yet.So, the R color lump of exhibit red and G, the B color lump of Show Color do not combine and make that just their pairing pixels are finally shown in red.
If the mixolimnion that the R color lump is corresponding partly is rendered as progressive state (the smectic liquid crystal molecule twists form for part); Then the R color lump demonstrate progressive state redness (for example; The redness of translucent), thus whole pixel externally demonstrates the redness of this progressive state.
For the W color lump, the arrangement form of liquid crystal molecule receives the control of the voltage signal on the corresponding row-column electrode equally and is arranged as out of order state (presenting vaporific lucifuge state) or rule state (presenting the bright state of full impregnated) or other transition states (presenting progressive state) in its pairing mixolimnion part.The W color lump does not have selective permeation function or stimulated radiation effect to light, and all light are always all through this W color lump, therefore; For example, if the corresponding mixolimnion of W color lump partly is vaporific lucifuge state, the external show white of W color lump then; So the brightness of this pixel increases, but the red purity that this pixel shows has received influence; If the mixolimnion that the W color lump is corresponding partly is the bright state of full impregnated, the external Show Color (principle is with above-mentioned G, B color lump) not of W color lump then, so; The red purity that this pixel shows improves (highest purity), but the relative step-down of the brightness of this pixel.In reality is implemented, reach balance in order to make between brightness of image and the colour purity, the demonstration of W color lump can be determined that for example, the mean value of desirable R, G, B color lump three color value is used as the brightness value of W color lump jointly by R, G, B color lump.
When light 30 when second base layer, 12 1 sides are injected; Displaying principle (like Figure 10) and above-mentioned light 30 that the R color lump is shown in red are basic identical from the situation of first base layer, 11 1 side directive R color lumps; Different is; Compare with light case of incident shown in Figure 9, the R color lump is a little to evening time of ruddiness selective permeation (for the color lump of optical filter making) or stimulated radiation (for the color lump of fluorescent powder making).And G, B color lump the situation injected from first base layer, 11 1 sides of principle and the above-mentioned light 30 of Show Color is not identical.
Pixel is except can being shown as the red, green, blue look; Also can make pixel be shown as other color through mixolimnion control partly to R, G, B color lump correspondence; So the whole screen of display has just had colourful color effects, reached the requirement that full color shows.Pixel displaying principle shown in green, blue and other color is identical with the displaying principle of above-mentioned pixel exhibit red, so here do not give unnecessary details.No matter which kind of color pixel is shown as; Displaying principle all can reduce: control the voltage signal (pulse of controlling this voltage signal is to number, frequency, voltage magnitude) that applies on the row-column electrode of R, G, B, W color lump correspondence respectively; Make the interior smectic liquid crystal molecules align of mixolimnion part of R, G, B, W color lump correspondence (for example become corresponding form; Regularly arranged form, out of order arrangement form, part are twisted form etc.); The mixolimnion part of R, G, B, W color lump correspondence (for example produces corresponding astigmatic effect respectively; Vaporific lucifuge state, the bright state of full impregnated, such as progressive state of translucent etc.), thereby R, G, B, W color lump demonstrate corresponding color respectively, the color combination that R, G, B, W color lump are shown gets up to be the color that their pairing pixels finally demonstrate.
For RGB type colour element layer 16; The difference of itself and RGBW type colour element layer is not have the W color lump; RGB type colour element layer can not be regulated the brightness and the colour purity of pixel Show Color, but its image displaying principle is identical with RGBW type colour element layer, here repeats no more.
In like manner; For RGBY type colour element layer 16; The difference of itself and RGBW type colour element layer is not have the W color lump, and RGBY type colour element layer can not be regulated the brightness and the colour purity of pixel Show Color, and the color that pixel finally demonstrates is to be got up to constitute by the color combination that R, G, B, four color lumps of Y show separately; The image displaying principle of RGBY type colour element layer is identical with RGBW type colour element layer, here repeats no more.
In like manner; For CMYK type colour element layer 16; The difference of itself and RGBW type colour element layer also is not have the W color lump, and CMYK type colour element layer can not be regulated the brightness and the colour purity of pixel Show Color, and the color that pixel finally demonstrates is to be got up to constitute by the color combination that C, M, Y, four color lumps of K show separately; The image displaying principle of CMYK type colour element layer is identical with RGBW type colour element layer, here repeats no more.
Can know by above-mentioned displaying principle; When display of the present invention is in outdoor light better in the environment of (bright and clear) time; Ambient light is from this display of all angles incident; So this display can before and after the two sides same width of cloth image of clear demonstration simultaneously, the relative another side images displayed of one side images displayed content content is overturn.That is to say that the beholder can see the image with identical display effect regardless of which side at display.
But; When display of the present invention be in indoor or environment that light is bad in the time, ambient light too a little less than, just can't satisfy the brightness requirement that image shows; Therefore; In order to improve the brightness that image shows, can at least one side of the LCD MODULE 10 of display of the present invention or near illumination module 17 is set, the two sides, front and back of LCD MODULE 10 is viewing area 50 (like Fig. 1 and Fig. 2); Illumination module 17 can not block viewing area 50; Illumination module comprises a plurality of irradiation lights 171, and these a plurality of irradiation lights 171 other light that are provided with irradiation light 171 emissions carry out deflection, the lens 172 so that light tilts on one of them viewing area 50 of directive equably or two viewing areas 50.The inclination directive here is meant that the light of directive viewing area 50 and the plane of viewing area 50 form an acute angle; And light is equably to the whole planar transmit of viewing area 50, and the whole plane of viewing area 50 is appeared needs images displayed.Irradiation light 171 can adopt LED or CCFL, and LED can be blueness or white.Lens 172 can be that transparent materials such as PMMA, PC are processed.In display of the present invention, these illumination module 17 roles promptly are outdoor preferably light roles, and the light of their directive viewing areas 50 all tilts.
As shown in Figure 3; Shown in the figure is near the situation the lower side of illumination module 17 LCD MODULE 10 that is arranged on display of the present invention; This illumination module 17 is positioned at the front of LCD MODULE 10; The light of irradiation light 171 emission of this illumination module 17 through lens 172 (lens 172 are arranged on the top of irradiation light 171) deflection after, on that viewing area 50 of directive LCD MODULE 10 fronts equably of tilting.As shown in Figure 3, these illumination module 17 roles promptly are outdoor preferably light roles, and the light of this viewing area 50 of their directives all tilts.Because display of the present invention shown in Figure 3 only is provided with the illumination module 17 to viewing area 50 irradiation light; There is not another viewing area 50 of light source irradiation can only receive the irradiation of more weak surround lighting; Therefore, though this display can show same width of cloth image in the two sides, front and back simultaneously; The viewing area 50 of having only light source irradiation is display image clearly, and the image that does not have the viewing area 50 of light source irradiation to demonstrate is not very clear.The image displaying principle of display of the present invention shown in Figure 3 is identical with the present invention that illumination module 17 is not set, and here repeats no more.
Tilt evenly to two viewing areas 50 of the LCD MODULE 10 of display of the present invention that the illumination module 17 of emission light does not provide diagram, please combine situation shown in Figure 3 to understand.When all there is the irradiate light that irradiation light 171 sends former and later two viewing areas 50 of the LCD MODULE 10 of display of the present invention; Display of the present invention can before and after the two sides same width of cloth image of clear demonstration simultaneously; Its image displaying principle is identical with the present invention that illumination module 17 is not set, and here repeats no more.
It should be noted that; Because on light source (referring to illumination module 17) direction of illumination, there are a large amount of transmitted lights, rather than the required scattered light of image demonstration, and these transmitted lights can make each color lump Show Color all the time; Therefore; It is parallel with the illumination direction of light source that view direction will be avoided as far as possible, and the illumination direction of light source should stagger with beholder's direction of visual lines mutually, so just can reach good viewing effect.
Also can consult number of patent application about the light modulation principle in the mixolimnion (being how the smectic liquid crystal molecule is arranged by driving accordingly) is that 200710175959.9 Chinese invention patent application " a kind of electric-controlled light-regulating medium " and number of patent application are that corresponding description in Chinese invention patent application " electric-controlled light-regulating medium " of 200810102000.7 etc. is understood.
In the present invention, after producing luminous effects such as scattering, full impregnated be bright for first, second conductive electrode layer on-load voltage signal, the present invention, just can remove voltage.The maintenance of this luminous effect does not need voltage to keep, promptly remove voltage after, the luminous effect that the present invention produces in the time of still can keeping on-load voltage, and the voltage signal of effect is just in order to change the arrangement form of smectic liquid crystal molecule.In the present invention, this state that does not need electricity to drive and keep luminous effect is called " multistable " or " quasistatic ".And this " multistable " is because conducting objects has adopted the compound of band conductive characteristic; When voltage signal is applied on first, second conductive electrode layer; Ion in the compound of band conductive characteristic changes the generation to-and-fro movement according to electric potential difference; This motion can change the arrangement form of smectic liquid crystal molecule, and the smectic liquid crystal molecules align form after changing does not need the persistent movement of ion to keep, and is stable.
In the present invention, also can be mixed with dichroic dye in the mixolimnion 13.Preferably, dichroic dye can account for and mix 5% of general assembly (TW).Through an amount of dichroic dye is mixed into mixolimnion 13, can make the mixolimnion of display of the present invention realize bright, the coloured shading of full impregnated, the various switching that has between the color shade attitude.For the display of the present invention that is mixed with dichroic dye in the mixolimnion 13, its images displayed be the color that shows of colour element layer 16 with mixolimnion 13 in the stack of color of dichroic dye demonstration.The image displaying principle that is mixed with the display of the present invention of dichroic dye in the mixolimnion 13 is essentially identical with the present invention who does not add dichroic dye; Different just these displays one deck color that on the basis of colour element layer 16 display image, superposeed again shows; Make the colour of display abundanter; Therefore, the image displaying principle that is mixed with the display of the present invention of dichroic dye in the mixolimnion 13 no longer here details.
