Abstract

The invention discloses a light diffraction device, a display substrate, a touch substrate and a manufacturing method of the touch substrate. The light diffraction device is used for diffracting emergent lights of the display substrate and comprises a photorefractive crystal block, an electrode structure and a control structure, wherein the photorefractive crystal block is corresponding to at least one pixel unit in the display substrate, and the photorefractive crystal block is preformed with holographic grating; the electrode structure is arranged on two opposite side surfaces of the photorefractive crystal block; and the control structure is used for inputting voltage to the electrode structure, and an electric field is formed between the two opposite side surfaces of the photorefractive crystal block, and at least part of the emergent lights passing through the display substrate is diffracted after passing through the holographic grating under the action of the electric field. By virtue of the light diffraction device disclosed by the invention, the aim that viewing angle and brightness of light rays can be controlled is achieved, so that user experience effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light diffraction device, a display substrate, a touch substrate and a manufacturing method thereof. Background technique [0002] Under different conditions, users have different viewing angle requirements for display devices. However, most of the existing TN (Twist Nematic, twisted nematic) mode products have a relatively small viewing angle, which is difficult to meet the user's viewing angle requirements, even the ADS (Advanced superDimension Switch, Advanced Super Dimension Switch, which has obvious advantages in wide viewing angles) field conversion technology) products, its brightness is also very low at large viewing angles. Therefore, if a display device product with controllable viewing angle and brightness can be provided, it will certainly be able to satisfy users' demands for multiple viewing angles of the display device. Contents of the invention [0003] The...
