Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
As shown in Figure 1, as one aspect of the present invention, provide a kind of display panel 100, wherein, this display panel 100 comprises the first panel 110 and the second panel 120, first panel 110 for showing image, and the second panel 120 is arranged on the light emission side of the first panel 110.The odd-numbered frame of the first panel 110 shows one group of image, and the even frame of the first panel 110 shows another group image.Second panel 120 is liquid crystal panel, be provided with the first polaroid 111 between first panel 110 and the second panel 120, the polarisation of light direction penetrated from the second panel 120 when the first panel 110 shows odd-numbered frame image becomes predetermined angular with the polarisation of light direction penetrated from the second panel 120 when the first panel 110 shows even frame image.
The principle of work of display panel provided by the present invention is explained below in conjunction with Fig. 2 a and Fig. 2 b.
Because the first polaroid 111 is arranged on the incident side of the second panel 120, therefore, the light injecting the second panel 120 is the polarization direction linearly polarized light identical with the polarizing axis direction of the first polaroid, that is, the polarization direction injecting the light of the second panel 120 is D1.In fig. 2 a, liquid crystal molecule in second panel does not deflect, from the second panel 120, the polarization direction of the light of outgoing remains D1, in figure 2b, the liquid crystal molecule in the second panel there occurs deflection, therefore, in the process that light is propagated in liquid crystal molecule in a second panel, polarization direction is changed, and when light penetrates from the second panel, its polarization direction becomes D2.
When display panel display image provided by the present invention, need to wear corresponding polaroid glasses.
When the polarization direction of polaroid glasses is with when during odd-numbered frame, the polarization direction of emergent light is identical, the image shown when can see the first panel odd-numbered frame by these polaroid glasses.When the polarization direction of polaroid glasses is identical with the polarization direction of emergent light during even frame, the image shown when can see the first panel even frame.
If the first panel is different with the image shown during even frame in odd-numbered frame, two different beholders wear above-mentioned two kinds of glasses respectively, then can see different images.
Such as, utilize respectively the first glasses 210 and secondary glasses 220 and liquid crystal panel provided by the present invention with the use of.The polarization direction of the eyeglass of the first glasses 210 is identical with the polarization direction of emergent light during the first Display panel odd-numbered frame image, and the polarization direction of the eyeglass of secondary glasses 220 is identical with the polarization direction of emergent light during the first Display panel second panel even frame.A beholder wears the first glasses 210, and another beholder wears secondary glasses 220.First polaroid is equivalent to polarizer slice, and the first glasses 210 are equivalent to checking bias slice during odd-numbered frame, and secondary glasses 220 is equivalent to checking bias slice during even frame.The beholder wearing the first glasses 210 can see the image that the first panel shows when odd-numbered frame; The beholder wearing secondary glasses 220 can understand the image that the second panel shows when even frame.When utilizing display panel provided by the present invention to show two picture, the restriction not special to the viewing angle of beholder.
It is to be understood that the above described said odd-numbered frame of this programme and even frame are the frame pictures in normal display.That is, the time interval between adjacent odd-numbered frame image is enough short, and, the time interval between neighbouring even-numbered two field picture is also enough short, make the user wearing corresponding glasses viewing odd-numbered frame image can see the image of display continuously, and can not feel time interval between frame and frame, the user wearing corresponding glasses viewing even frame image can see the image of display continuously, and can not feel the time interval between frame and frame.
As noted before, the first panel 110 image shown when odd-numbered frame belongs to same group of image, and the first panel 110 image shown when even frame belongs to another group image.First panel 110 image shown when odd-numbered frame can be different from the first panel 120 image shown when even frame, and namely the first panel can realize two picture display.The image seen by the first glasses 210 is like this different from the image seen by secondary glasses 220.Certainly, the image that the first panel 110 image shown when odd-numbered frame can be shown when even frame with the first panel 110 is identical, and the image seen by the first glasses 210 is like this also identical with the image seen by secondary glasses 220.
