Problems solved by technology

Secondly, in practical applications, the common light guide plate and diffuser plate are made of plastic. When applied to a large-size LCD screen, the expansion coefficient of the plastic material is relatively large, resulting in a relatively large black border area (BM area) of the LCD screen.

Abstract

The invention discloses a glass light guide plate and glass diffusion plate fused backlight structure which sequentially comprises a reflecting plate, a glass light guide plate, a diffusion ink layer,a glass diffusion plate, an OCA adhesive and an optical film from inside to outside. Light guide net points are printed on the back face of the glass light guide plate. An LED light source group is arranged on the side of the glass light guide plate. The glass light guide plate and the glass diffusion plate are used for replacing an existing plastic light guide plate and an existing plastic diffusion plate, and the expansion coefficient in application is reduced. The glass light guide plate and the glass diffusion plate are fused together, and display is achieved in a side-entry backlight mode. The whole structure is simple and the reliability is strong.

Description

technical field [0001] The invention relates to the technical field of liquid crystal screen backlight structures, in particular to a backlight structure fused with a glass light guide plate and a glass diffusion plate. Background technique [0002] At present, LED display is still the mainstream technology. Taking LCD TV (also known as LED backlight TV, commonly known as LED TV) as an example, in terms of the principle of light emission, it consists of a light source and a transparent panel with a picture. The transparent panel itself does not emit light, and imaging requires another crucial component - the backlight. When the picture of the transparent panel changes and the light source provides it with light, we can see a dynamic and bright picture. LED LCD TV uses LED light as the backlight source of the TV, providing stable brightness and color performance. [0003] There are usually two types of LED backlights. First, according to the color of the light source emit...
