Embodiment 1

[0027] Method 1 is described in detail as follows:

[0028] Figure 2-1 shows a cross-sectional view of the working principle of adding a liquid crystal light interlaced twisting layer, where part A is the original basic structure of the liquid crystal, and part B is the added part.

[0029] Among them, part A of Figure 2-1 is the working principle of conventional liquid crystals. The light passes through 1 incident light polarizing film -> 2 glass -> 3 guiding film -> 4 liquid crystal -> 5 guiding film -> 6 glass -> 7 outgoing polarized light For each layer of the film, the light is twisted by 4 liquid crystals, and when it is emitted, the amplitude of the light has been twisted by an angle of 90 degrees (also refer to Figure 1-1).

[0030] Part B is an added part of the present invention, and its working principle is: when the pipeline exits the seventh layer, a layer of liquid crystal light twisting layer is added alternately, and the upper part of Figure 2-1 is the line wit...

Embodiment 2

[0035] The second method is described in detail as follows:

[0036] As shown in Figure 2-2: when manufacturing a liquid crystal display, the corresponding interlaced vertical mutual polarization process is performed on the 1a incident polarizer and the 7a output polarizer, and the 3a and 5a guiding films of the liquid crystal are also correspondingly processed. Interlaced lines are processed perpendicular to each other. After that, the whole LCD screen works normally like this, the light l1 and l2 pass through 1a polarizer -> 2 glass -> 3a liquid crystal guide plate -> 4 liquid crystal twisted 90 degrees -> 5a guide plate -> 6 glass -> due to The polarized light of 1a and 7a is perpendicular to each other, and the light is twisted by 90 degrees just to be sent out. Because the two polarizing films inside and outside the corresponding position (same pixel) are rotated 90 degrees at the same time, and the liquid crystal is also rotated 90 degrees, so all the circuit work does ...

Embodiment 3

[0038] The details of method three are as follows:

[0039]The difference between this scheme and ordinary liquid crystal display is that the incoming and outgoing light polarizers are not in the same direction of the whole sheet, but interlaced and vertical (as shown in Figure 1-3b). It is a mixed product of the two working modes of constant light and long dark (here it is assumed that the odd field is long dark, as shown in the figure: 2-3a and the half of the dotted line in Figure 2-3b; the even field is the long bright mode, as shown in the figure : 2-3a and the lower half of the dotted line in Fig. 2-3b). The light guides of the two polarizing films of a normally bright liquid crystal display are perpendicular to each other, as shown in Figure 1-1 and 1 and 7 in Figure 1-2, that is, as shown in Figure 2-3a and under the dotted line in Figure 2-3b Half of the area belongs to the current working mode of liquid crystal. In this case, light can pass through without power on,...

Abstract

A method for preparing liquid crystal stereo-plane in compatible with display adds odd number line or even number line of 90 degree light polarization liquid crystal twisted layer on surface of screen when liquid crystal display screen is prepared. The other two methods for preparing liquid crystal stereo-plane in compatible with display are also disclosed.

Description

technical field [0001] The invention relates to a liquid crystal stereoscopic plane compatible display. Background technique [0002] With the development of liquid crystal technology, many scientists have begun to consider whether the principle of 3D glasses can be directly used to realize this function on the liquid crystal display. At present, the most realistic technology is jointly created by Philips and Sharp, and the first successfully commercialized 3D liquid crystal display manufactured by using this technology has also been launched on the market. [0003] This is by adding an array of lenses on the outermost layer of the liquid crystal, and forming an image on this layer of convex lens arrays. Each lens is placed at a small angle with the LCD pixels, and corresponds to 7 LCD cells. Each LCD pixel is composed of 3 liquid crystal cells, which have the function of displaying RGB three colors. After adopting 3D liquid crystal technology, the original RGB color is no...
