Problems solved by technology

The backlight assembly provides light source for the LCD screen, and its performance plays a big role in the display effect. Generally, the light direction is required to be single, but because the LCD pixels are too small and the adjacent distance is small, it is easy to cause backlight interference. Cause screen display problems

Embodiment Construction

[0008] An embodiment provided by the present invention: a method for shielding the backlight of a liquid crystal display. The frame of the backlight is made into a funnel shape, and the bottom of the funnel is an inclined plane. parallel state;

[0009] Then the parallel light is constrained by the parallel surface at the front of the funnel, and finally irradiated to the liquid crystal pixels.

[0010] Working principle: Because of the backlight interference, the light from the backlight is scattered after being emitted, which leads to mutual interference. The structure of the present invention corrects the light to a parallel state by forming a slope near the backlight, and then constrains it through the front parallel surface, thereby greatly Reduce backlight scattering and avoid backlight mutual interference.

[0011] It will be apparent to those skilled in the art that the invention is not limited to the details of the above-described exemplary embodiments, but that the ...

Abstract

The invention discloses an LCD backlight shielding method. The frame of a backlight lamp is manufactured into a hopper shape, the bottom of the hopper is an inclined surface, the backlight lamp is covered with the bottom of the hopper, and the light is rectified to be in a parallel state by the aid of the inclined surface at the bottom of the hopper; the parallel light of the parallel surfaces of the front end of the hopper is restrained, and finally the light is irradiated to liquid crystal pixels. According to the LCD backlight shielding method, the inclined surface is formed nearby the backlight lamp, and the light is rectified to be in the parallel state and is restrained by the parallel surfaces of the front end, so that the backlight scattering is reduced greatly, and the condition that backlight interferes mutually is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to a backlight shielding method for liquid crystal display screens. Background technique [0002] Simply put, the LCD module is the screen and backlight components. The display part of the LCD TV is the LCD module. Other parts include power supply circuits, signal processing circuits, etc., and of course the casing. The module is mainly divided into screen and backlight components. The backlight assembly provides light source for the LCD screen, and its performance plays a big role in the display effect. Generally, the light direction is required to be single, but because the LCD pixels are too small and the adjacent distance is small, it is easy to cause backlight interference. Cause screen display problems. Contents of the invention [0003] The object of the present invention is to provide a method for shielding the backlight of a liquid crystal displ...
