Problems solved by technology
[0005] In practical applications, since the width of the narrow transparent conductive strip is small, its maximum width is equivalent to the width of a sub-pixel, so the resistance of the narrow transparent conductive strip is very large, not only the manufacturing process is difficult, but also the large resistance will cause serious signal loss , which reduces the display quality
Although the resistance can be reduced by increasing the thickness of the narrow transparent conductive strips, this will undoubtedly increase the production cost

Embodiment Construction
[0020] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0021] figure 1 It is a structural schematic diagram of the first embodiment of the liquid crystal shutter slit grating of the present invention. Such as figure 1 As shown, the liquid crystal shutter slit grating in this embodiment includes a first grating substrate 10 and a second grating substrate 20 that are boxed together and a liquid crystal 30 is interposed therebetween. Each grating substrate includes a substrate 1, a grating layer 2, and an alignment film. 3 and a polarizer 4 , the grating layer 2 on the first grating substrate 10 is relatively offset from the grating layer 2 on the second grating substrate 20 . Specifically, the grating layer 2 is formed on the substrate 1 and is composed of transparent conductive strips 5 with the same width and arranged in sequence. Adjacent transparent conductive strips...

The invention relates to a liquid crystal shutter slit grating which comprises a first grating substrate and a second grating substrate which are combined together, wherein liquid crystal is clamped between the first grating substrate and the second grating substrate; the first grating substrate and the second grating substrate respectively comprise a grating layer, an orientation film and a Polaroid which are formed on the substrates; and the grating layers on the first grating substrate and the second grating substrate are relatively staggered. In the invention, the grating layers are formed on the substrates and formed by sequentially arraying transparent conducting bars with identical widths; and the transparent conducting bars on the first grating substrate and the transparent conducting bars on the second grating substrate are oppositely arranged and relatively staggered along the vertical direction of the transparent conducting bars. In the invention, the structure that the widths of the transparent conducting bars are the same and the transparent conducting bars on the two grating substrates are staggered is adopted, and compared with the prior art, because the widths of the transparent conducting bars are wider, in the invention, not only is the manufacturing process difficulty is greatly reduced, but also the resistance of the transparent conducting bars is reduced and the product quality is improved.
Description
technical field [0001] The invention relates to a stereoscopic display device, in particular to a liquid crystal shutter slit grating. Background technique [0002] Autostereoscopic display technology refers to a display technology that can observe stereoscopic effects without eyes, and the core component to realize autostereoscopic display is grating. In the prior art, lens grating and slit grating are two main technologies. Among them, the slit grating can be divided into black and white strip slit grating and liquid crystal shutter slit grating. The liquid crystal shutter slit grating can not only be used for stereoscopic display, but also switch between two-dimensional (2D) display and three-dimensional (3D) display. [0003] The liquid crystal shutter slit grating is a kind of TN mode liquid crystal panel. When it is powered on, it displays black stripes, and the adjacent black stripes can transmit light, forming a slit grating with black and white stripe intervals, wh...
