Description

technical field

[0001] The present invention relates to a device and method for controlling and adjusting the temperature of a display device, more specifically, the present invention refers to a device for adjusting the temperature gradient of a liquid crystal module, and a method for temperature adjustment using this device, It also includes a liquid crystal module using the device. Background technique

[0002] The principle of liquid crystal display is to encapsulate liquid crystal in glass to make a liquid crystal screen, and then apply an electric field to change the orientation of liquid crystal molecules, and then use a light source to project the converted light into the liquid crystal screen through an optical film to achieve the purpose of display. The side-light LED liquid crystal module is to place the LED light source on the side of the liquid crystal module. The principle is to use the light guide plate and the optical film to convert the light emitted by the ...
