Reflective membrane and backlight module capable of preventing non-uniform brightness of two sides of displayer

Abstract

The invention discloses a reflective membrane and backlight module capable of preventing non-uniform brightness of the two sides of a displayer. The backlight module includes an upper module frame, alower module frame, a light guiding plate and diffusion particles; lock buckles are installed on the two sides of the bottom of the upper module frame respectively, a horizontal polaroid is arranged on the top of the interior of the upper module frame, a colored filter is arranged at the bottom of the interior of the upper module frame, a lower module frame is disposed below the upper module frame, and locking grooves matched with the lock buckles are installed at the two ends of the two sides of the lower module frame respectively; the light guiding plate is installed above the reflective membrane, clamping grooves are formed in the tops of the two sides of the interior of the lower module frame respectively, and a liquid crystal board is arranged between the clamping grooves. A circuit board is installed on the top of the liquid crystal board, an anti-dazzling screen is installed on the top of the circuit board, and TFT glass is installed on the top of the anti-dazzling screen. By installing mounting bases at the bottoms of the two sides of the lower module frame respectively, the backlight module is conveniently fixed and installed.

Description

technical field [0001] The invention relates to the technical field of electronic product parts, in particular to a reflective film and a backlight module capable of preventing uneven brightness on both sides of a display. Background technique [0002] With the continuous development of society, my country's electronics industry is developing very rapidly. Display screens are needed in electronic products. The most important part inside the display screen is the reflective film and backlight module. [0003] The reflective film is a part of the material of the LCD backlight module. It is located at the bottom of the backlight module and under the light guide plate. Its function is to reflect the light leaked through the light guide plate and return to the panel side Thereby reducing light loss and increasing brightness. [0004] The types of reflective film are mainly divided into two categories: white reflective film and silver-plated mirror reflective film. According to t...

AI Technical Summary

Problems solved by technology

[0005] There are many problems or defects in the existing reflective film and backlight module. First, the traditional reflective film and backlight module do not have the function of preventing uneven brightness on both sides of the display. Second, the traditional reflective film and backlight module do not It is easy to disassemble and install. Third, the traditional reflective film and backlight module have poor heat dissipation capabilities, and they are prone to premature aging and reduced service life when working in a high-temperature environment for a long time.
