Problems solved by technology

[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.

Abstract

The embodiment of the invention provides a water-cooling heat dissipation display module, and the display module comprises a display panel and a lamp panel, wherein a plurality of LED lamp beads are arranged on the top face of the side, close to the display panel, of the lamp panel, and a heat dissipation cavity is formed at the bottom of the side, away from the display panel, of the lamp panel. A cooling water strip is arranged in the heat dissipation cavity and arranged along the inner surface of the heat dissipation cavity. According to the display module provided by the invention, the cooling water strip is arranged in the heat dissipation cavity, so that the heat dissipation rate can be increased, the normal working temperature of the lamp panel is ensured, the phenomenon of overhigh temperature is avoided, and the light emitting efficiency, the working stability and the service life of the LED lamp beads are ensured to be normal. In addition, due to the fact that the heat generated by the lamp panel is absorbed in time, the working stability of the display panel can be guaranteed.

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...
