The switchable plane-stereoscopic display comprises a liquid crystal display panel and a switchable grating. The liquid crystal display panel comprises a display area, a non-display area surrounding the display area and a first black matrix extending from the display area to the non-display area, wherein, the first black matrix is provided with a plurality of pin holes which are arranged in a matrix shape and only distributed in the display area. The switchable grating is provided with a stereopicture control area, a non-display area surrounding the stereopicture control area and a second black matrix which is only arranged in the non-display area, wherein, the second black matrix surrounds the stereopicture control area and the area of the stereopicture control area is different from the area of the display area.
Description
Technical field
The invention relates to a kind of switchable plane and solid display (switchable two and threedimensional display), and particularly relevant for a kind of switchable plane and solid display with switchable grating (switchable barrier).
Background technology
In recent years, along with the continuous progress of display technique, the user is also more and more higher for the requirement of the display quality (as image analytic degree, color saturation etc.) of display.Yet except hi-vision resolution and high color saturation, for the user, whether display can show that stereo-picture also becomes one of considerations in the purchase.
The stereo-picture display technique that development is at present come out mainly is to utilize fixed grating to control audience's left eye and the received image of right eye.According to the visual characteristic of human eye, see respectively when images of left and right eyes and to look identical picture material but when having two images of different parallaxes (parallax), human eye can be observed a stereo-picture.According to the difference of fixed stop position, stereo display technique can be divided into haply two kinds of preceding raster pattern (front barrier) stereo display technique and back raster pattern (back barrier) stereo display techniques.
Preceding raster pattern stereo-picture display technique is the place ahead that grating is disposed at display panel, anticipates promptly, and grating is between display panel and human eye; Then raster pattern stereo-picture display technique then is that grating is disposed between backlight and the display panel.Can be about preceding raster pattern stereo-picture display technique with reference to the content of U.S. Patent Publication case US 2004/0257531, then raster pattern stereo-picture display technique then can be with reference to the content of U.S. Patent Publication case US 2007/0229654A1.
It should be noted that, utilize fixed grating to produce the mode that stereo-picture belongs to a kind of space multiplex (MUX) (spatial-multiplexed), though this mode can reduce by half the resolution of three-dimensional display so that display panels has the effect of stereo display.In addition, the three-dimensional display with fixed grating can only be used for showing stereo-picture and can't the display plane image.For the user, the practicality of three-dimensional display with fixed grating is not high.
For addressing the above problem, a kind of switchable grating (switchable barrier) is applied in the switchable plane and solid display, so that switchable plane and solid display can demonstrate plane picture under the situation that switchable grating is not unlocked.When switchable grating was unlocked, switchable plane and solid display just can demonstrate stereo-picture.
Fig. 1 is the diagrammatic cross-section of known a kind of switchable plane and solid display.Please refer to Fig. 1, known switchable plane and solid display 100 comprises a display panels 110 and a switchable grating 120.Display panels 110 has a viewing area 110a, and extends to the first black matrix 112 (blackmatrix) of non-display area 110b around the non-display area 110b of viewing area 110a and from viewing area 110a, and wherein the first black matrix 112 has and a plurality ofly is arranged and only is distributed in fairlead 112a in the viewing area.Switchable grating 120 has a stereo-picture control zone 120a, a non-display area 120b and around stereo-picture control zone 120a and only is disposed at the black matrix 122 of second on the non-display area 120b, wherein second deceives matrix 122 around stereo-picture control zone 120a, and the area of stereo-picture control zone 120a is identical with the area of viewing area 120b.
As shown in Figure 1, because the outer rim of stereo-picture control zone 120a can be in alignment with the outer rim of viewing area 120b, therefore when the user watched known switchable plane and solid display 100, will discover image very easily had the visual effect condition of poor in edge.The main cause that causes this phenomenon is that the second black matrix 122 can't cover the first black matrix 112 fully on user's sight line, and the user is easy to discover the first black matrix 112 that is positioned at the place, image border.
Summary of the invention
The invention provides a kind of switchable plane and solid display, its shown image is difficult for the phenomenon that has visual effect bad in edge.
The present invention proposes a kind of switchable plane and solid display, is suitable for allowing a user watch, and this switchable plane and solid display comprises a display panels and a switchable grating.Display panels has a viewing area, a non-display area and around the viewing area extend to non-display area from the viewing area the first black matrix, and wherein the first black matrix has and a plurality ofly is arranged and only is distributed in fairlead in the viewing area.Switchable grating is disposed between display panels and the user, wherein switchable grating has a stereo-picture control zone, a changeable shielded area around the stereo-picture control zone, a non-display area and around changeable shielded area and only is disposed at the black matrix of second on the non-display area, and the area of stereo-picture control zone is less than the area of viewing area.
In one embodiment of this invention, the area of viewing area equals the area summation of stereo-picture control zone and changeable shielded area in fact.
In one embodiment of this invention, changeable shielded area is positioned at top, part viewing area.
In one embodiment of this invention, the width of changeable shielded area is W
3, and the bee-line between the first black matrix and the changeable control zone is D
3, and satisfy the following relationship formula:
W
3/D
3≥W
H/D
H，
W wherein
HBe half of the width of viewing area, and D
HBe the default distance of viewing and admiring, and default eyes that distance is essentially the user distance of the inside surface of a plate base wherein to the display panels of viewing and admiring.
In one embodiment of this invention, switchable grating has second control electrode that first control electrode and that is positioned at the stereo-picture control zone is positioned at changeable shielded area, and first control electrode has a plurality of perforates.
In one embodiment of this invention, the second above-mentioned control electrode is a ring electrode.
In one embodiment of this invention, above-mentioned switchable plane and solid display more comprises a backlight module, and display panels is disposed between switchable grating and the backlight module.
In switchable plane and solid display of the present invention, because the area of the stereo-picture control zone of switchable grating is different with the area of the viewing area of display panels, so the present invention can avoid the shown image of switchable plane and solid display the bad phenomenon of visual effect to occur in edge.
