Embodiment
The embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explain the present invention, and is not intended to limit the invention.
As shown in figure 1, as one aspect of the present invention, there is provided a kind of display panel 100, wherein, the display panel 100
Including first panel 110 and second panel 120, first panel 110 is used for display image, and second panel 120 is arranged on the first face
The light emission side of plate 110.The odd-numbered frame of first panel 110 shows one group of image, and the even frame of first panel 110 shows another group of figure
Picture.Second panel 120 is liquid crystal panel, and the first polaroid 111 is provided between first panel 110 and second panel 120,
One panel 110 shows the polarization direction of the light projected during odd number two field picture from second panel 120 with showing idol in first panel 110
The polarization direction of the light projected during number two field picture from second panel 120 is into predetermined angular.
The operation principle of display panel provided by the present invention is explained with reference to Fig. 2 a and Fig. 2 b.
Because the first polaroid 111 is arranged on the incident side of second panel 120, therefore, the light of second panel 120 is injected
For polarization direction and the polarisation direction of principal axis identical linearly polarized light of the first polaroid, i.e. inject the inclined of the light of second panel 120
The direction that shakes is D1.In fig. 2 a, the liquid crystal molecule in second panel does not deflect, the light being emitted from second panel 120
The polarization direction of line is still D1, and in figure 2b, the liquid crystal molecule in second panel is deflected, and therefore, light is second
During being propagated in panel in liquid crystal molecule, polarization direction is changed, when light projects from second panel, its polarization side
To having been changed to D2.
In display panel display image provided by the present invention, it is necessary to wear corresponding polaroid glasses.
, can by the polaroid glasses when the polarization direction of polaroid glasses is identical with the polarization direction of emergent light during odd-numbered frame
To see the image shown during first panel odd-numbered frame.The polarization of emergent light when polarization direction and the even frame of polaroid glasses
When direction is identical, it can be seen that the image shown during first panel even frame.
If first panel is in odd-numbered frame with the image difference that is shown during even frame, two different beholders' difference
Above two glasses are worn, then it can be seen that different images.
Make for example, being utilized respectively the first glasses 210 and secondary glasses 220 and coordinating with liquid crystal panel provided by the present invention
With.The polarization direction of the eyeglass of first glasses 210 and the polarization direction phase of emergent light during first panel display odd number two field picture
Together, the polarization direction of the eyeglass of secondary glasses 220 and the polarization side of emergent light during first panel display second panel even frame
To identical.One beholder wears the first glasses 210, and another beholder wears secondary glasses 220.First polaroid equivalent to
Polarizer slice, checking bias slice when the first glasses 210 are equivalent to odd-numbered frame, checking bias slice when secondary glasses 220 are equivalent to even frame.Wear
The beholder for wearing the first glasses 210 can see the image that first panel is shown in odd-numbered frame；Wear the sight of secondary glasses 220
The person of seeing can understand the image that second panel is shown in even frame.Double pictures are being shown using display panel provided by the present invention
During face, the viewing angle of beholder is not particularly limited.
It is to be understood that the odd-numbered frame and even frame described in the above this programme are the frames in normal display
Picture.That is, the time interval between adjacent odd number two field picture is short enough, also, between neighbouring even-numbered two field picture
Time interval is also short enough so that the user of corresponding glasses viewing odd number two field picture can see what is continuously displayed in wearing
Image, and the time interval between frame and frame is not felt as, the use of corresponding glasses viewing even number two field picture in wearing
Person can see the image continuously displayed, and not feel as the time interval between frame and frame.
As mentioned above it is possible, the image shown in odd-numbered frame of first panel 110 belongs to same group of image, and the first face
The image shown in even frame of plate 110 belongs to another group of image.The image shown in odd-numbered frame of first panel 110 can
Can realize that double pictures are shown different from the image shown in even frame of first panel 120, that is, first panel.This
Sample is different from the image seen by secondary glasses 220 by the image that the first glasses 210 are seen.Certainly, first panel 110 exists
Shown image can be identical with the image that first panel 110 is shown in even frame during odd-numbered frame, so passes through first
The image that glasses 210 are seen and the image seen by secondary glasses 220 are also identical.
When display panel provided by the present invention shows double picture, by be used cooperatively with the display panel first
Glasses 210 can only watch odd number two field picture, can only be watched by the secondary glasses 220 being used cooperatively with the display panel
Even number two field picture, is not limited by viewing visual angle.Also, the resolution ratio of odd number two field picture show using the display panel and
The resolution ratio of even number two field picture is identical, is the full resolution image of no resolution loss.
In the present invention, the concrete structure of first panel 110 is not particularly limited, as long as can be in odd-numbered frame
Show one group of image, another group of image is shown in even frame.For example, first panel 110 can be organic light-emitting diodes
