Naked-eye 3D display module for games and preparation method of naked-eye 3D display module

Abstract

The invention relaters to a naked-eye 3D display module for games and a preparation method of the naked-eye 3D display module. The naked-eye 3D display module for games comprises a piece of grating glass and a liquid crystal layer; the liquid crystal layer is a piece of liquid crystal glass, the grating glass comprises a naked-eye 3D imaging material and a piece of optical super white glass which are attached by an optical adhesive layer; oriental attaching to locating points on the grating glass and the liquid crystal glass is performed by a high-definition camera. According to the naked-eye 3D display module for games and the preparation method of the naked-eye 3D display module, oriental attaching to locating points on the grating glass and the liquid crystal glass is performed by the high-definition camera, the alignment accuracy and the consistency are increased, and the production efficiency is improved to a great extent; the liquid crystal glass but not a liquid crystal display is adopted, so that full contact of the grating glass and the liquid crystal glass can be realized, the grating glass is directly attached to the liquid crystal glass by an attaching technology, and the flatness of the display module is improved greatly.

Description

technical field [0001] The invention relates to the technical field of naked-eye three-dimensional display of game equipment, in particular to two kinds of naked-eye 3D display modules for games and a preparation method thereof. Background technique [0002] Most of the currently used game devices are flat display or three-dimensional display with glasses, and those with naked-eye three-dimensional display are mostly used in tablet computers and mobile phones with a size of 10 inches or less. However, most of the mainstream display devices in the game industry are large screens of more than 10 inches. At this stage, there is no naked-eye 3D display module professionally used in games. The main reasons are: 1. The viewing distance required for games is very close; 2. It is required to have a large viewing angle, and no dizzy state can occur at 20 degrees to the left and right of the middle position; 3. Long-term viewing of the existing 3D presentation method will cause visual...

However, most of the mainstream display devices in the game industry are large screens of more than 10 inches. At this stage, there is no naked-eye 3D display module professionally used in games. The main reasons are: 1. The viewing distance required for games is very close; 2. It is required to have a large viewing angle, and no dizziness can occur at 20 degrees to the left and right of the middle position; 3. The existing 3D presentation method will cause visual fatigue when viewed for a long time

[0003] In the current traditional naked-eye 3D display module manufacturing process, most of them use human eyes to evaluate the display effect to confirm whether the alignment of the grating glass and the LCD screen fits well. The human factors are large, the product consistency is poor, and the production efficiency is low. , high scrap rate

Moreover, the current preparation process adopts the specific method of laminating the grating glass and the liquid crystal screen by placing the grating glass directly on the metal frame of the liquid crystal screen, but because the flatness of the metal frame itself is not very good, it is easy to cause a three-dimensional cycle. When transitioning to the next cycle, it will become an irregular diffusion transition, which will cause dizzy areas when viewing the display effect in any area within the range of 50-80 cm required by naked-eye 3D games; and because the grating glass is directly in contact with the LCD screen The metal frame is in contact with the LCD screen instead of the LCD screen (the LCD screen and the metal frame itself cannot be precisely combined), which will result in a small range of motion and cause quality defects in the product
