Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly relate to a kind of display panels and preparation method thereof.
Background technology
Usually, liquid crystal display upper surface arranges a polarising means, and thus display shines the light of intelligent's eye is line polarisation.But, the photosensory cell of human eye gets used to natural light, the polarization direction of natural light is the non-linear polarization light be evenly distributed in all directions, it is identical to the stimulation of human eye photosensory cell on each polarization direction, but human eye receive the only linearly polarized light of display, the photosensory cell of human eye only receives the luminous energy stimulation of a polarization direction, its stimulation obtained is lack of balance, observer easily occurs using asthenopic symptom when receiving linearly polarized light for a long time, therefore proposes rotatory polarization display significant.
Be illustrated in figure 1 the structural representation of the common circularly polarized light display of current display, it comprises the first polarizing layer 10 successively, first substrate 20, liquid crystal layer 30, second substrate 40 second polarizing layer 50 and backlight 60, wherein, at arranged outside 1/4 λ wave plate 70 and the surface-treated layer 80 of the first polarizing layer 10, by the 1/4 λ wave plate 70 in the first polarizing layer 10 arranged outside, the linearly polarized light of outgoing can be made to become circularly polarized light, but this circularly polarized light change and imperfect, because the phase delay delta nd=1/4 λ that 1/4 λ wave plate 70 produces can only corresponding some wavelength, normally 550nm (the some wavelength in centre of 380 ~ 780 wave bands), now 550nm and near it light of wavelength can change desirable circularly polarized light preferably into, but just comparatively perfectly can not change rotatory polarization into away from the light of 550nm (being less than or greater than 550nm) wavelength, because be greater than or less than 1/4 λ for its phase delay delta nd of light away from 550nm (being less than or greater than 550nm) wavelength.
Be illustrated in figure 2 1/4 λ wave plate common used material, phase delay delta nd/ (Δ n589) d of the 1/4 λ wave plate that normalization signal modification PC (modified polycarbonate) in figure, PC (polycarbonate), COC (cyclenes copolymer), TAC (Triafol T), COP (cycloolefine polymer), PMMA+LC (crylic acid resin+liquid crystal coating) make and wavelength relationship.The material wherein with modification PC material the same (Y-axis increases with wavelength and increases gradually) characteristic is referred to as inverse wave length dispersion, and the material wherein with PMMA+LC material the same (Y-axis increases with wavelength and reduces gradually) characteristic is referred to as the long dispersion of downsea.1/4 desirable λ waveplate material is as shown in Fig. 2 cathetus, during for use this kind of material same thickness, phase delay delta nd can increase from 380 ~ 780nm with wavelength and increase, and make the light of each wavelength that the phase delay of 1/4 λ can occur, but this material does not exist.
Illustrate as shown in Figure 4 and adopt phase delay delta nd=1/4 λ, the wave plate of λ=550nm, for the B away from 550nm, elliptically polarized light is changed into after R light transmission 1/4 λ wave plate, suppose that through the light intensity of RGB before sunglasses be R:G:B=1:1:1, but be R:G:B ≠ 1:1:1 through the light intensity of sunglasses (sunglasses having polarizing layer structure) RGB afterwards, thus result in as Fig. 3 a, color distortion shown in 3b, and the 1/4 λ wave plate that positive wavelength and inverse wave length material are being made is when arranging over the display, best observation angle under sunglasses all different (when the chromaticity coordinates difference through sunglasses front and rear is minimum), this observation angle is that the polarizing axis of sunglasses is to the angle with polaroid axis on display.
Can find that current rotatory polarization display exists following defect based on above-mentioned actual conditions and theory:
1) becoming elliptically polarized light away from the light fixing certain wavelength, is not more perfect circularly polarized light;
2) the 1/4 λ wave plate made of different materials, the best observation angle under different sunglasses is different;
2) altered a great deal by color during sunglasses viewing display picture.
