3D (Three Dimensional) display screen and laminating method thereof

Abstract

The invention relates to a 3D (Three Dimensional) display screen. The 3D display screen comprises: a liquid crystal display screen, a 3D film, a liquid glue layer, a sticking layer and a touch screen, wherein the 3D film comprises: a base layer and a bulge-shaped prism column; the prism column is arrayed on the base layer; the bottom surface of the 3D film is laminated on the liquid crystal display screen; the liquid glue layer covers the top surface of one side of the prism column of the 3D film, so that the top surface of the 3D film covered with the liquid glue layer is a flat plane; the touch screen is laminated with the top surface of the 3D film covered with the liquid glue layer together through the sticking layer.

Description

technical field [0001] The invention relates to the field of electronic equipment assembly, in particular to a 3D display screen and a bonding method thereof. Background technique [0002] The distance between the human eyes is about 6-7 cm. It is precisely because of the distance of 6 to 7 centimeters that when people's eyes look at an object, the scenes they see are not the same, but there are subtle differences. This visual difference between the two eyes of the human body makes people have a three-dimensional sense when observing external things. 3D (3Dimension) imaging technology is realized according to this principle. [0003] figure 1 It is a schematic diagram of the principle of 3D imaging. The light emitted by the left light source behind the 3D film is refracted by the 3D film and then enters the left eye of the human body. The light emitted by the right light source behind the 3D film is refracted by the 3D film and then enters the human body. Right eye: Beca...

AI Technical Summary

Problems solved by technology

refer to image 3 , the full bonding method has the following defects: because the refractive index of OCA / OCR is different from that of air, the emitted light will be refracted after passing through the OCA / OCR layer, resulting in the inability to form a correct image, and the user cannot see the 3D effect

Therefore, the thickness of the frame glue must be greater than 3mm, resulting in a very thick thickness of the entire 3D display module;

[0007] 2. There is air between the touch screen and the 3D film, which will scatter the light entering from the outside and the backlight, causing the screen to look white when the screen is off. When the screen is on, the brightness of the backlight will be insufficient under strong light. The screen display is not clear;

[0008] 3. The sealing is not good enough. After a long time of use, the inside of the screen is easy to enter dust and water vapor
