Description
Technical field
The invention relates to a kind of 3D display, relate to a kind of rotatable 3D display especially.
Background technology
So-called stereopsis is exactly except the X-axis of plane and Y-axis, also will have the obvious degree of depth.General employing utilizes mankind's images of left and right eyes institute angle slightly different, receive the parallax effect that image has small size difference, automatically mutually compensate in the brain and merge and the stereopsis that formed, and all can maintain under the situation of static and movement.The image energy that images of left and right eyes can be allowed to see namely is wanted to have a little difference.
With current stereopsis technology, spectacle (stereoscopic) 3D technology can be divided into and nakedly look (auto stereoscopic) 3D technology.Spectacle 3D Technical Development History is long, and early stage 3D three-dimensional film utilizes mycyscope to present effect.But, because mycyscope technology only can present better effect under GTG or dull color background, fresh few employing at present.
The commercial technologies of current main flow mainly can divide 2 kinds, polaroid glasses formula (polarizingglasses) and shutter glasses (shutter glasses) formula technology respectively, the former cost is lower, therefore market adopts comparatively universal, but vertical angle of view and resolution poor, the latter can solve ghost problem, but high expensive.
But, 3D stereopsis could be enjoyed still bring user, suitable inconvenience in any case have on glasses.
Therefore, the application of bore hole 3D technology arises, and is mostly used on the small-size screens such as mobile phone at present, with the 3D image effect presented.But the technology of bore hole 3D, although can direct viewing, and no longer needs to wear polaroid glasses.But, the technology of bore hole 3D is mainly by the mode of directive property backlight, disparity barrier (barrier type) or lens pillar (lenticular lens), the right and left eyes of audience is allowed to occur parallax effect, so that allow image seem really have certain stereoscopic sensation.
But the technology of known bore hole 3D, once determine the angle presentation of 3D image, just not easily changes the angle of display.Therefore, the technology of known bore hole 3D to be also improperly used on the portable electronic devices that usually needs to change angles of display.How changing the angle presentation of 3D display, is the direction of display dealer institute develop actively.
Summary of the invention
Described in above-mentioned prior art, be nakedly not easy depending on 3D technology the angle changing 3D display due to traditional, often cause the restriction in use.Therefore, how effectively can improve and nakedly to look 3D image technology, make it can change 3D angles of display according to the demand of user, not only can significantly promote 3D image technology, 3D display more can be facilitated to be used in portable electronic devices.
An object of the present invention, is to provide rotatable 3D display, can change 3D angles of display according to the demand of user.
According to above-described object, the present invention discloses a kind of rotatable 3D display, include a upper electrode substrate, a lower electrode substrate and a liquid crystal layer, be configured between this upper electrode substrate and this lower electrode substrate, and utilize those strip top electrodes or those strip bottom electrodes to control the angle of liquid crystal in this liquid crystal layer, this liquid crystal layer is made to form a liquid crystal lens, to present a 3D image.

In addition, when each group electrode is odd number, middle strip electrode can also be selected, make it consistent with the voltage of the common electrode on another substrate, to make the leading edge formation one preferably curve of liquid crystal lens, reduce the discontinuous problem of liquid crystal lens angle.The another rough change then can effectively avoiding the voltage difference of strip electrode to be formed in liquid crystal by uniform electric field layer, and then make the Angulation changes of liquid crystal more level and smooth.Particularly, uniform electric field layer not can be used only in the side that liquid crystal lens controls substrate, to make liquid crystal lens curve smoothing, uniform electric field layer more can in common electrode side, make the voltage of common electrode more consistent, particularly when the voltage of common electrode is greater than 0 volt, the voltage of common electrode side is effectively made to maintain a uniform magnitude of voltage.
Therefore, rotatable 3D display of the present invention can watch the direction of display easily according to user, the angle of the liquid crystal needed for decision, the liquid crystal lens needed for formation, and then provides suitable 3D image, display can also be switched to the display of 2D.In addition, rotatable 3D display of the present invention, by strip top electrode or bottom electrode, to control the angle of liquid crystal, to form multiple lens pillar, and then shows 3D image.Each lens pillar preferably can be controlled by multiple top electrode or bottom electrode, preferably the top electrode of more than three or bottom electrode controlled, more preferably the top electrode of more than five or bottom electrode controlled, make the angle of lens pillar more level and smooth, and by uniform electric field layer that electrode dielectric layer is formed, the curved surface of each lens pillar can also be made more level and smooth, consult the liquid crystal lens 150 of Fig. 2 and Fig. 3.
Because rotatable 3D display of the present invention adopts liquid crystal 3D lens, and the strip top electrode utilizing formation one predetermined angular to configure and strip bottom electrode control the angle of liquid crystal, therefore it can according to the three-dimensional viewpoin of different use angles adjustment image.When user is longitudinally to watch display frame, now, image frame forms longitudinal stereopsis.Otherwise when user is laterally to watch display frame, now, picture forms horizontal stereopsis.Therefore, user can easily under different visual format, the image of viewing 3D, and only can not can form the stereopsis of 3D as known stereopsis under single angle.
As person skilled in the art understand, the foregoing is only preferred embodiment of the present invention, and be not used to limit claim of the present invention.Under all other does not depart from disclosed spirit, the equivalence that completes changes or modifies, and all should be included in the scope of claims.
