Problems solved by technology
Therefore, the left and right edge areas of the strip electrode A area of the upper substrate and the lower substrate form an irregular fringe electric field, resulting in irregular arrangement of the liquid crystal molecules in the edge area, so that the area corresponding to the a electrode is not completely black, and the b area is not. Full bright state, there will be gray scale changes
This may lead to severe 3D interference and inconsistent grayscale display, affecting the 3D display effect
At the same time, the display state of the black state area and the light transmission area in the existing TN type liquid crystal grating is fixed, and the dislocation movement of the light shielding area and the light transmission area cannot be realized, which seriously affects the resolution and brightness of 3D display.

Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments and related drawings.
[0032] The invention provides a method for controlling a dynamic liquid crystal grating. The dynamic liquid crystal grating includes a first control layer, a second control layer, a liquid crystal layer, and a control module. The first control layer includes a first electrode and a first electrode. Two electrodes, the second control layer includes a third electrode; the voltage applied to the first electrode, the second electrode and the third electrode is changed by the control module to drive the liquid crystal molecules of the liquid crystal layer to deflect , so as to control the dynamic liquid crystal grating to be in different working states, and the working states include:
[0033] In the first working state, the voltage applied by the control module to...

The invention relates to the technical field of display, in particular to a dynamic liquid crystal grating control method. The control method is characterized in that a dynamic liquid crystal grating comprises a first control layer, a second control layer, a liquid crystal layer and a control module, the first control layer comprises a first electrode and a second electrode, and the second control layer comprises a third electrode. The control module is used for controlling voltage between the first electrode, the second electrode and the third electrode to adjust alternate dislocation movement between a light-shielding area and a light-transmitting area of the fluid crystal grating, improve 3D display resolution, further reduce response time of dynamic shift of the liquid crystal grating, reduce 3D display harass and improve 3D display effect. Meanwhile, the control method can switch display modes between a 2D display mode and a 3D display mode according to displayed contents.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a dynamic liquid crystal grating and a three-dimensional display device including the grating. Background technique [0002] Human beings perceive the depth of an object through the subtle difference between the objects seen by the right eye and the left eye, and thus recognize the stereoscopic image. This difference is called parallax. Stereoscopic display technology is to create the parallax of the left and right eyes of people through artificial means, and send two images with parallax to the left and right eyes respectively, so that the brain can observe the real three-dimensional objects after obtaining the different images seen by the left and right eyes. a feeling of. There are generally two types of stereoscopic display devices: a slit grating type stereoscopic display device and a microlens array stereoscopic display device. Among them, the slit grating type includes ...
