Problems solved by technology

But in the actual design, if the pitch becomes larger, the OD value will become larger, which will affect the appearance
To reduce the OD value, it is necessary to reduce the pitch value, resulting in an increase in the number of LEDs

Abstract

The invention discloses a light source plate, which comprises a light source plate main body, a plurality of LEDs arranged on the light source plate main body at intervals and a light reflecting layer arranged above the LEDs, wherein the light reflecting layer comprises a plurality of light reflecting patterns arranged at intervals, and each LED corresponds to one light reflecting pattern. The reflective coating does not completely cover protective glue, and light reflection is increased, so that the effect that light is diffused farther and more evenly can be achieved on the premise that the distance between the backlight plate and a liquid crystal diffusion sheet is not adjusted or even shortened.

Description

technical field [0001] The application belongs to the technical field of display screens, and in particular relates to a light source board, a manufacturing method of a backlight source, a steel mesh and a backlight module. Background technique [0002] In LCD liquid crystal display technology, it is a feasible technology to use LED, especially miniLED and microLED direct-lit backlight, with Local Dimming (regional dimming) technology to achieve high brightness, high contrast, high image quality and color viewing angle innovation. [0003] The distribution pitch (pitch) of Mini LED chips and the distance (OD value) from the backlight panel to the liquid crystal diffuser are a pair of contradictory parameters. Considering the cost, we hope that the distribution pitch of Mini LEDs should be as large as possible, which can reduce the number of LEDs used, thereby reducing costs. Considering the application design, we hope that the OD value should be as small as possible, so th...
