Description

A liquid crystal module ultra-narrow bezel backlight structure

technical field

The utility model relates to the technical field of liquid crystal display equipment, in particular to a backlight source structure of a liquid crystal module capable of splicing a large-screen liquid crystal wall.

Background technique

With the improvement of people's living standards and the level of science and technology, liquid crystal display devices have been widely used because of their advantages such as high definition, portability, and low energy consumption, such as LCD TVs, liquid crystal displays, notebook computers, and the like. In the prior art, the appearance and structure of all LCD modules on the market are composed of a metal back panel combined with a plastic middle frame and a metal upper frame, so there will be a wider frame after assembly, especially for LCD TVs. The frame of the module will exceed 25mm or more. The wider frame not only looks unattractive, limits the viewing area of the screen, but also increases the weight of the device and wastes materials. With the development of market demand towards ultra-light and ultra-thin, there are corresponding requirements for the frame of the product. Visually, the narrower the frame is, the larger the viewing area will be, and the overall appearance will be more beautiful, and the ultra-narrow edge is splicing a large screen. When the gap in the middle can be further narrowed, the display effect of the screen can be improved.

Utility model content

The technical problem to be solved by the utility model is to provide an ultra-narrow frame backlight structure of a liquid crystal module with an ultra-narrow frame, a large viewing area, and easy splicing.

In order to solve the above technical problems, the utility model adopts the following technical scheme: a liquid crystal module ultra-narrow frame backlight structure, including a liquid crystal glass screen, an optical diffusion plate and a diaphragm, a backlight light-emitting area, and a lamp in the backlight light-emitting area The tube assembly, the liquid crystal glass screen is set on the outermost layer, the optical diffusion plate and the diaphragm are arranged under the liquid crystal glass screen as a whole, and the backlight light-emitting area is set under the optical diffusion plate and the diaphragm, which is characterized in that it is located around The bottom surface of the black edge banding area of the liquid crystal glass is equipped with an adhesive strip with double-sided pasting function. The metal back panel structure is pasted under the adhesive strip. Structural pieces bonded together.

Further, the cross-section of the hardware back plate structure is an inverted "L" shape, and the width of its upper plane is the same as the width of the black edge sealing area of the liquid crystal glass.

Further, the adhesive strip is a black shock-absorbing double-sided adhesive strip.

The utility model replaces the traditional frame by sticking adhesive strips on the bottom of the black edge sealing area of the liquid crystal glass to paste the hardware backboard structure, so that the visible area of the screen reaches the maximum and the frame is the narrowest, which not only saves materials, The weight is reduced, and the splicing of LCD glass screens is more convenient and the effect is better.
