Abstract

The invention relates to a device and a method for controlling and regulating a temperature of display equipment, in particular to a device for regulating a temperature gradient of a liquid crystal module and a method for adjusting the temperature by utilizing the device, as well as the liquid crystal module utilizing the device. According to the device provided by the invention, the temperature of an overall machine can be increased to a normal working temperature as soon as possible, and the delay phenomenon when a liquid crystal television is turned on is improved; the temperature in the overall machine can be balanced during working, a gradient of temperature distribution of a whole backlight system is reduced, and phenomena of heated light leakage and the like are avoided; the heating temperature of the device is constant, a resistor can be automatically adjusted according to the temperature, addition of a control unit is not needed, and the structure is simple; and meanwhile by the adoption of low-pressure direct-current electricity, the device has remarkable protective functions aiming to current overload, voltage overload and temperature overheat, and has excellent safety.

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 ...
