Method of LCD display heat dissipation

Now, LCD is a very common display # 10.1 inch car capacitive touch screen #. It has advantages of small size, light weight, power saving, low radiation, and easy portability. More and More industrial instruments and equipment are applied to LCD # 3.2'' TFT touch LCD display #. When the instrument is working, the heat generated by equipment makes the internal temperature of the equipment rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of the equipment will decrease. No matter what kind of electronic product   # 240x320 TFT LCD display # it is, Heat dissipation is very important, it affects the use and life of the equipment to a certain extent.

Method of LCD heat dissipation

1、Air hydrodynamics, using the shape of the lamp housing to create convection air, which is a low-cost way to enhance heat dissipation.

2、Thermally conductive plastic shell # 1.7 inch tft lcd #, fill the thermal conductive material during injection molding of the plastic shell to increase the thermal conductivity and heat dissipation capacity of the plastic shell.

3、Aluminum heat dissipation fins, this is a common heat dissipation method, using aluminum heat dissipation # 1.44 inch LCD  # fins as part of the shell to increase the heat dissipation area.

4、Surface radiation heat dissipation treatment, the outer surface of the lamp housing is treated with radiation heat dissipation treatment. The simple thing is to modify the radiation heat dissipation paint # IPS TFT display module #, which can take away from the surface of the lam housing radiation.

5、The heat pipe is used for heat dissipation, and the heat pipe technology is used to conduct the heat from the LCD# 3.5 480x320 TFT LCD screen display #full-color display chip to the heat dissipation fins of the shell. It is a common design in large lamps such as street lamps.

6、The fan dissipates heat, and the long-life high-efficiency fan is used inside the lamp housing to enhance heat dissipation. This method is low in cost and good in effect. However, it is a hassle to replace the fan the it is not suitable for outdoor use, which is relatively rare.

7、Liquid bulb, use liquid bulb packaging technology to fill the transparent liquid with high thermal conductivity into bulb of the lamp body. In addition to the principle of reflection, this is the skill of using the light-emitting surface of the LCD  # 3.9 inch TFT  # chip to conduct heat and heat dissipation.

8、Integration of heat conduction and heat dissipation - the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp housing is to reduce the working temperature of the LCD # TFT SPI #full-color display chip, because the expansion coefficient of the LCD  # 2 inch touching display # chip is very different from the expansion coefficient of our usual metal heat conduction and heat dissipation materials. Weld theLCD # 3.5 inch display screen # chip directly to avoid high and low temperature thermal stress from damaging theLCD # TFT LCD 2.4 inch 240x320 display module #full-color display  #3.5 touch display # chip. The new high thermal conductivity ceramic material, the thermal conductivity is close to that of aluminum, and the expansion system can be adjusted to be synchronized with theLCD # 1.8 inch TFT LCD display module # full-color display chip. In this way, heat conduction and heat dissipation can be integrated, and the intermediate process of heat conduction can be reduced.
