A water-cooled display module

Abstract

An embodiment of the present invention provides a water-cooled and heat-dissipating display module. The display module includes a display panel and a lamp board. A plurality of LED beads are arranged on the top surface of the lamp board near the display panel. A cooling cavity is provided at the bottom of the lamp board away from the display panel; a cooling water belt is arranged in the cooling cavity, and the cooling water belt is arranged along the inner surface of the cooling cavity. The display module provided by the present invention can increase the heat dissipation rate by arranging cooling water belts in the heat dissipation cavity, ensure that the working temperature of the lamp panel is normal, and will not cause excessive temperature, thereby ensuring the luminous efficiency and stable operation of the LED lamp bead The normality of sex and service life. In addition, because the heat generated by the light board is absorbed in time, it can also ensure the stable operation of the display panel.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a water-cooled and heat-dissipating display module. 【Background technique】 [0002] With the vigorous development of the automobile industry, the requirements for the brightness of vehicle-mounted display products are getting higher and higher, which makes the number and power consumption of LEDs in vehicle-mounted backlights continue to increase, resulting in a sharp rise in the temperature of the backlight; and the photoelectric conversion rate of LEDs is relatively low. Low, a large amount of electric energy will be converted into heat energy during work. If the heat cannot be dissipated in time, the temperature of the LED chip will be too high, which will affect the service life, luminous efficiency and stability of the LED; at the same time, too high temperature will also make the liquid crystal The electro-optical performance of the display panel changes, affecting the u...

[0002] With the vigorous development of the automobile industry, the requirements for the brightness of vehicle display products are getting higher and higher, which makes the number and power consumption of LEDs in vehicle backlights continue to increase, resulting in a sharp rise in the temperature of the backlight; and the photoelectric conversion rate of LEDs is relatively low. Low, a large amount of electric energy will be converted into heat energy during work. If the heat cannot be dissipated in time, the temperature of the LED chip will be too high, which will affect the service life, luminous efficiency and stability of the LED; at the same time, too high temperature will also make the liquid crystal The electro-optical performance of the display panel changes, affecting the use of the entire product

In the prior art, the heat of the backlight is generally transferred to the air, and the heat is taken away by the air for heat dissipation, but the efficiency of air transmission and heat dissipation is low, and the stable operation of the backlight and the display panel cannot be guaranteed.
