An ultra-thin direct type backlight module

Abstract

The invention discloses an ultra-thin direct-lit backlight module. The backlight module includes a backlight plate. The backlight plate is provided with a light guide plate and a film structure. The light guide plate is located between the backlight plate and the film structure. There are plastic parts on both sides of the material structure, and an LED light source is installed between the light guide plate and the backlight plate. The light guide plate includes a prism structure, and there is a groove under the light guide plate. plate. The backlight module of the present invention makes the LED light source installed on the backlight board by rotating the rotating part, which is convenient for installation and maintenance; the LED light source is located in the groove, effectively changing the direction of the light source, and the light is refracted through the prism structure to achieve atomization of the light source The effect is to adjust the uniform distribution of the light source, avoid the phenomenon of bright particles, effectively reduce the height of the direct-type backlight cavity, replace the vertical distance between the original diffuser plate and the LED light source, reduce the thickness of the backlight source, and achieve an ultra-thin effect.

Description

technical field [0001] The invention relates to a backlight module, in particular to an ultra-thin direct type backlight module. Background technique [0002] In the current direct-lit backlight design, the diffusion plate above the LED is used to uniformly atomize the LED light source to ensure the uniformity of brightness in each area of ​​the product. In order to avoid bright spots and halos on the screen caused by LED particles, in general direct-type backlight design, a certain distance must be kept between the diffuser plate and the LEDs to ensure that the light source is evenly dispersed. Therefore, the existence of the distance makes the direct-type backlight generally thicker, which cannot be achieved. Ultra-thin design of side-type backlight. Contents of the invention [0003] The purpose of the present invention is to provide an ultra-thin direct-lit backlight module. By rotating the rotating part, the LED light source is installed on the backlight board, which...
