Description
Technical field
The utility model relates to 3D field of liquid crystal display, in particular a kind of slit liquid crystal grating of high permeability.
Background technology
Along with the development of display technique, the application of 3 d display device is also more and more wider.The stereo display of parallax formula is that optical modulation assembly makes the right and left eyes image of flat-panel screens display steric information be supplied to left eye and the right eye of beholder respectively, and then the two width anaglyphs synthesis obtained can perceive and realize stereo display by the brain of beholder.The glasses constraint of spectacle 3D has been broken away from bore hole stereo display, improves the comfort level of beholder.It is the developing direction of following display.Free 3 D display technology phase colorimetric based on parallax is divided, light divide with time to grade wear-type 3-D display, due in the constraint objectively breaking away from the auxiliary devices such as anaglyph spectacles, improve the comfort level of viewing and widened application and be subject to extensive concern.The method realizing naked eye visible stereo image display at present has multiple, such as column grating, liquid crystal grating etc.Wherein liquid crystal light grating 3D system and device as shown in Figure 1, is made up of liquid crystal grating 1, LCD 2, drive system.It has the switchable advantage of 2D/3D, and shortcoming is that brightness is low.When making liquid crystal grating, particularly large-sized liquid crystal grating, in order to control the homogeneity after liquid crystal cell, generally all needs to adopt photoresistance.
The structure of traditional liquid crystal light is as Fig. 2, and lower transparency carrier 101 is liquid crystal grating electrode 102. liquid crystal grating electrode 102 on lower transparency carrier 101 is strip electrodes, concrete live width, line-spacing according to reality need design.Upper transparency carrier 105, liquid crystal grating electrode 104 below upper transparency carrier 105, grating electrode 104 is transparent metal electrodes of whole, it is photoresist layer 106 below liquid crystal grating electrode 104, photoresist layer 106 plays the thick effect of supporting case, be liquid crystal layer 103 between two substrates, become 90 degree of frictions up and down.Drive system is V to the voltage difference of grating electrode 102,104, and when V has enough ability driving liquid crystal, the optical effect figure of liquid crystal grating, as Fig. 3, is equivalent to black and white slit.Owing to there being the existence of photoresistance in white seam the inside, have impact on the transmitance of light, reduce 3D brightness.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of slit liquid crystal grating of high permeability.
The utility model is achieved through the following technical solutions: a kind of slit liquid crystal grating of high permeability, comprise the first transparency carrier, second transparency carrier, first liquid crystal grating electrode, second liquid crystal grating electrode, photoresist layer, liquid crystal layer, first transparency carrier and the second transparency carrier are oppositely arranged, first liquid crystal grating electrode is arranged on inside the first transparency carrier, second liquid crystal grating electrode is arranged on inside the second transparency carrier, inside the second liquid crystal grating electrode, photoresist layer is set, between photoresist layer and the first liquid crystal grating electrode, liquid crystal layer is set, first liquid crystal grating electrode is strip electrode, it is characterized in that: on photoresist layer, photoresistance is set with the equitant region of strip electrode of the first liquid crystal grating electrode.
As improvement, the second liquid crystal grating electrode is the transparent metal electrode of whole.
The utility model has the following advantages compared to existing technology: the utility model, by the design to photoresistance position distribution, makes the position of photoresistance avoid the open region of liquid crystal grating, so just can improve the aperture opening ratio of liquid crystal grating, improves the brightness of 3D.Do not changing the aperture opening ratio of liquid crystal grating, when not changing original process conditions, improve the penetrance of light, improve the brightness of liquid crystal light grating 3D display system, overcome the deficiency of existing bore hole 3D technology, the 3D that improve user experiences, and accelerates liquid crystal grating bore hole 3D systematic difference and popularizes.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
The slit liquid crystal grating of a kind of high permeability as shown in Figure 4, comprise the first transparency carrier 101, second transparency carrier 105, first liquid crystal grating electrode 102, second liquid crystal grating electrode 104, photoresist layer 106, liquid crystal layer 103, first transparency carrier 101 and the second transparency carrier 105 are oppositely arranged, first liquid crystal grating electrode 102 is arranged on inside the first transparency carrier 101, second liquid crystal grating electrode 104 is arranged on inside the second transparency carrier 105, inside the second liquid crystal grating electrode 104, photoresist layer 106 is set, between photoresist layer 106 and the first liquid crystal grating electrode 102, liquid crystal layer 103 is set, first liquid crystal grating electrode 102 is strip electrodes, the live width that strip electrode is concrete, line-spacing according to reality need design, second liquid crystal grating electrode 104 is transparent metal electrodes of whole, it is characterized in that: on photoresist layer 106, photoresistance is set with the equitant region of strip electrode of the first liquid crystal grating electrode 102, by such design.
In practical work process, when applying voltage between the first liquid crystal grating electrode 102 and the second liquid crystal grating electrode 104, liquid crystal aligning is made to be arranged in the strip electrode region of the first liquid crystal grating electrode 102, realize grating function, its optical effect as shown in Figure 4 and Figure 5, because photoresistance is all arranged in strip electrode region, can not stop light through, both can realize the function strengthening 3D display brightness.
