Backlight module with anti-light-leakage function

Abstract

The invention discloses a backlight module with an anti-light-leakage function. The backlight module comprises a main frame body, a rubber frame is arranged in the main frame body, and the upper end and the lower end of the right part of the main frame body are connected with the rubber frame through bolts; LED lamp strips are arranged at the upper end and the lower end of the left side wall in the rubber frame, a plurality of cold cathode fluorescent lamp tubes are arranged at the left part in the rubber frame, and the two ends of each cold cathode fluorescent lamp tube are connected with therubber frame; a backlight plate is arranged at the left part in the rubber frame, and a light guide plate is arranged on the portion, on the right side of the backlight plate, in the rubber frame. The outer side of rubber is fixedly connected to the inside of the main frame body when the module works, the outer side wall of the rubber frame and the main frame body can fully prevent external lightfrom interfering with the interior, and light rays can also be prevented from being emitted out of internal gaps. When the internal temperature is high, an air blower sucks air into a cooling box through a connecting pipe, the air is in contact with a cold water pipe, the temperature is gradually reduced, the cooled air enters an air outlet pipe and then is blown out from an air blowing opening in a vertical pipe, and the interior of the rubber frame can be cooled.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a backlight module with the function of preventing light leakage. Background technique [0002] The backlight module is one of the key components of the LCD panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The so-called backlight is a kind of light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. Liquid crystal itself does not emit light, it displays graphics or characters as a result of its modulation of light. The backlight module is the provider of the light source of the liquid crystal display. The LCD itself does not emit light. Can occupy a place in the CRT market. [0003] With the improvement of liquid crystal display manufacturing technology and the trend of large size and low ...

AI Technical Summary

Problems solved by technology

The existing backlight module is an important part of the liquid crystal display module, which plays the role of luminous display, but when the user watches the picture from the side of the liquid crystal display, the backlight module will leak light

And the backlight module will generate a lot of heat when it is used for a long time, which will cause the display screen to malfunction. Therefore, those skilled in the art have provided a backlight module with a light leakage prevention function to solve the above-mentioned problems in the background technology. proposed question
