Abstract

The invention relates to a structural improvement of steric liquid crystal displays, comprising two liquid crystal display panels and an optical thin-film which can be penetrated through by optical lines and has no polarization effects. The optical thin-film is arranged between the two liquid crystal display panels, wherein, the upper and lower surfaces of the lower liquid crystal display panel are provided with an upper and a lower polaroids while the upper surface of the upper liquid crystal display panel is equipped with a delayed film. Therefore, when audiences can wear polarizing glasses to watch images, the left and right pictures can be displayed respectively by the two liquid crystal display panels through the steric liquid crystal display. Furthermore, the effect of depth produced by the simultaneous display of the two liquid crystal displays leads to more prominent steric images and facilitates to eliminate the phenomena of dark-and-light Morrie caused by optical interference on steric images.

Description

Stereo-liquid crystal display device
Technical field
The relevant a kind of LCD stereoscopic display of the present invention refers to that especially a kind of audience of order sees the structural improvement of the stereo-liquid crystal display device that stereopsis comparatively highlights.
Background technology
Usually, stereopsis is according to stereoscopic vision (stereo eyesight) principle that sees through human eyes, that is the distance existence that is approximately 65mm binocular parallax occurs and forms because eyes are separated by.In other words, eyes see through retina and see two different bidimensionals (2D) image that is sent to human brain, and human brain is combined to the degree of depth and entity with the regeneration real image with two images.
And wherein a kind of stereoscopic imaging apparatus comprises a lenticule and a parallax barrier.This stereoscopic imaging apparatus may in conjunction with or an additional conversion equipment so that show 2D image and 3D image.For example, an additional converting unit and has the lenticule (with reference to international monopoly (WO patent) 03/015424-A2 number) of refraction ansiotropy or in conjunction with a converting unit and a delayer (retarder) (with reference to United States Patent (USP) No. 6046849, No. 6055013, No. 6437915) or in conjunction with the Polarizer (with reference to United States Patent (USP) No. 4717949, No. 6157424) that a converting unit and is provided with the crack this stereoscopic imaging apparatus can be changed 2D image and 3D image mutually.
Use this lenticular this holographic display device typically to comprise a display panel, a lenticule panel, and a converting unit.This lenticule panel is a most important parts wherein, and along with this lenticule panel is made by precision, this holographic display device can clearly illustrate stereopsis.Yet, be formed on this lenticule panel lenticule during fabrication between on have many problems.
In addition, also favourable design with grating, the image that right and left eyes is seen is separated, its principle is to increase by a twisted nematic grating in liquid crystal display device module, or two groups of twisted nematic gratings, as number No. 266077 patent of TaiWan, China patent announcement then two groups of complementations to the row grating, open grating respectively at frequency odd number or even number respectively, make right and left eyes when odd number, even number frequency, can see an independent image separately, and then form a stereopsis.And because left and right sides picture all with a slice display panel, though can produce stereopsis, still can't show space or depth perception.
Summary of the invention
The present invention, its fundamental purpose shows the right and left eyes picture for a stereo-liquid crystal display device is provided respectively by two display panels, and shows the depth effect of generation simultaneously by two display panels, makes that stereopsis is better to highlight.
Second purpose of the present invention, by the blooming between two liquid crystal panels, make between first liquid crystal panel and second panel and produce a spacing, make the light that sees through liquid crystal bug hole (CELL), not because of the printing opacity hole influence of liquid crystal bug hole (CELL) spacing, can overcome the folded line phenomenon of light and shade of diffraction, the interference of light.
The 3rd purpose of the present invention at the surface structure by blooming, produces outside the spacing two panels, also produces a clearance at blooming, makes glass can not produce applying adherence phenomenon, the hot spot situation that produces in the time of can avoiding adherence.
Therefore, the structure of stereo-liquid crystal display device of the present invention is constituted by two display panels and middle blooming, and the light and shade that can be used for destroying and eliminate LCD is folded the light interference phenomena of line.
