Be example with lustre adding layer below, principle of work of the present invention be described with prism structure 220:
As Fig. 1, drive control device controls is applied to the voltage signal on two conductive electrode layers 104 and 105, make each pixel in the display layer 100 according to showing needs corresponding vaporific attitude of frosted or the bright state of full impregnated of presenting.If black backsheet layer 300 is set, corresponding black or the white (the bright state of the corresponding full impregnated of black, the vaporific attitude of white corresponding frosted) of showing as of pixel then, LCD is also with regard to the corresponding white and black displays state that is rendered as.
Particularly, according to showing needs, control the voltage signal on each strip shaped electric poles in each conductive electrode layer, the smectic phase liquid crystal molecule of each pixel correspondence in the display layer 100 presents corresponding ordered state---out of order ordered state or regularly arranged state.
With a pixel is the example explanation:
If this pixel is according to showing needs; be subjected to the voltage signal (100v for example on its corresponding strip shaped electric poles; driving pulse about 1kHz) control; its corresponding smectic phase liquid crystal molecule becomes regularly arranged; the long optical axis of smectic phase liquid crystal molecule is perpendicular to first; the plane of second conductive electrode layer; then the incident ray of injecting from the outside is via protective seam 400; display layer 100 parts of this pixel correspondence; lustre adding layer 200 and directive backsheet layer 300; via the reflection of backsheet layer 300 and pass through lustre adding layer 200 successively; display layer 100 parts of this pixel correspondence and protective seam 400 and directly penetrate; the ray refraction of each smectic phase liquid crystal molecule of incident does not produce acute variation; this pixel presents the bright state of full impregnated, the backsheet layer 300 of corresponding black and show black.
If this pixel is according to showing needs; be subjected to the control of the voltage signal (for example driving pulse about 100v, 50Hz) on its corresponding strip shaped electric poles; its corresponding smectic phase liquid crystal molecule twists; become out of order arrangement; then the incident ray of injecting from the outside enters in display layer 100 parts of this pixel correspondence via protective seam 400; in display layer 100 parts of this pixel correspondence, light reflects the back and penetrates in the smectic phase liquid crystal molecule, inject lustre adding layer 200.The light of injecting lustre adding layer 200 may be via lustre adding layer 200 back directive backsheet layers 300, also may be reflected back toward display layer 100 parts of this pixel correspondence and reflect once more.And, behind the light directive lustre adding layer 200 of backsheet layer 300 with reflected back, because lustre adding layer 200 designs have prism structure 220, the light of penetrating back from backsheet layer 300 may be reflected directive backsheet layer 300 once more by lustre adding layer 200, display layer 100 parts that also may inject this pixel correspondence via lustre adding layer 200 change directions once more reflect, and the like.The light that reflects in display layer 100 parts of this pixel correspondence produces dispersion effect, is penetrated by protective seam 400 at last.Particularly, in display layer 100 parts of this pixel correspondence, because each of smectic phase liquid crystal molecule (promptly passed through the long optical axis difference of each liquid crystal to diversity owing to incident ray, the anaclasis angle difference of each liquid crystal, thereby the refractive index difference of each liquid crystal), make the ray refraction of each smectic phase liquid crystal molecule of incident exist very big difference, promptly in display layer 100 parts of this pixel correspondence, optical index is producing violent variation, strong scattering has taken place in light in display layer 100 parts of this pixel correspondence, on macroscopic view, be a kind of astigmatic effect, present vaporific shading state, as acute-matte.This shows, lustre adding layer 200 among the present invention can increase the interior number of times of display layer 100 parts that light is injected this pixel correspondence, increase the interior amount of light of display layer 100 parts of this pixel correspondence, more rays is reflected in display layer 100 parts of this pixel correspondence, thereby strengthen the dispersion effect of display layer 100 parts of this pixel correspondence, the brightness of the vaporific attitude of frosted that this pixel presents is improved.Compare the backsheet layer 300 of the corresponding black of this pixel and shown the very high white of brightness with other black pixel points outside this pixel.Compare with existing smectic liquid crystal display screen, the contrast between the black that demonstrates on this white and the display is obviously strengthened.
It should be noted that, here no longer describe in detail about the light modulation principle in the display layer 100 (be smectic phase liquid crystal molecule how to be driven accordingly arrange), see also the patent No. and be 200710304409.2 Chinese invention patent " driving circuit for smectic state LCD display ", number of patent application and be 200710175959.9 Chinese invention patent application " a kind of electric-controlled light-regulating medium " and number of patent application and be the corresponding light modulation principles illustrated in 200810102000.7 the Chinese invention patent application " electric-controlled light-regulating medium ".
After producing luminous effects such as scattering, full impregnated be bright for first, second conductive electrode layer load driver pulse, 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 phase 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 additive has adopted the compound of band conductive characteristic, when electric 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 phase liquid crystal molecule, and the smectic phase Liquid Crystal Molecules Alignment form after changing does not need the persistent movement of ion to keep, and is stable.
Certainly, the pulse that is applied to the driving pulse on first, second conductive electrode layer by reasonable control is to number, frequency, voltage magnitude or action time, can make the arrangement form of smectic phase liquid crystal molecule become the part distortion, to produce astigmatic effect in various degree, thereby on macroscopic view, make pixel of the present invention between two states of the bright state of vaporific attitude of frosted and full impregnated, produce multiple progressive state, as translucent etc. with different gray scales rank.
In addition, in mixolimnion 103, also can be mixed with a certain amount of dichroic dye,, here not describe in detail as flaxen azo group dichroic dye.
Advantage of the present invention is:
The illustrious component of the lustre adding layer design among the present invention can carry out repeatedly reflected refraction with the light of injecting display, increase light number of times and the quantity injected in the display layer, more rays in being shown as the display layer part of pixel correspondence of the vaporific attitude of frosted, needs is reflected, thereby enhancing dispersion effect, the pixel of the vaporific attitude of frosted is strengthened because of the reinforcement brightness of dispersion effect, thereby the contrast between the pixel of the pixel of the vaporific attitude of frosted and the bright state of full impregnated significantly improves, strengthen the display effect of display of the present invention, increased reading, the comfort of watching.Simultaneously, because the illustrious component of lustre adding layer designs, increased the visible angle of smectic-state liquid crystal display of the present invention.If design has illustrious component on first base layer, then it also can produce the effect of above-mentioned enhancing contrast ratio equally.
The design of AR film and/or AG film makes the protective seam among the present invention play and prevents that display surface from producing the effect of direct reflection, thereby beholder's eyesight has been protected in display surface does not produce reflective, dazzle.The design of particle makes the protective seam among the present invention to the light on the directive display surface certain scattering process be arranged; make protective seam have to prevent display surface from producing the effect that direct reflection, display surface do not produce reflective and dazzle, heavy seal coat hardness, protected the surface of display well.
Reflection appears display to the color that backsheet layer among the present invention has itself through ambient light, also can increase the contrast between vaporific attitude of pixel frosted and the bright state of full impregnated, strengthens reading, the viewing effect of display of the present invention.
Certainly, because display design of the present invention has the display layer that is made of smectic phase liquid crystal and additive, thereby, it also has many advantages of bringing because of display layer, for example, multistable characteristic, energy consumption are low, environmental protection etc., here no longer describe in detail, and the associated advantages that sees also number of patent application and be 200710175959.9 Chinese invention patent application " a kind of electric-controlled light-regulating medium " and number of patent application and be in 200810102000.7 the Chinese invention patent application " electric-controlled light-regulating medium " is described.
The above is the know-why of preferred embodiment of the present invention and utilization thereof; for a person skilled in the art; under the situation that does not deviate from the spirit and scope of the present invention; any based on conspicuous changes such as the equivalent transformation on the technical solution of the present invention basis, simple replacements, all belong within the protection domain of the present invention.
