Background technique

The display is an I/O device belonging to the computer, that is, an input and output device. It can be divided into CRT, LCD and other types. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. Displays are also often referred to as monitors. The display is an I/O device belonging to the computer, that is, an input and output device. It can be divided into CRT, LED, LCD, PDP, OLED and so on. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

However, the LED display screen will generate a lot of heat after long-term operation, and the heat will accumulate in the glue-filled display module, which will cause the internal temperature of the display screen to be too high, which will not only affect the luminous intensity and luminous life of the LED chip , resulting in a decline in the overall display effect of the display screen. At the same time, high temperature will also have an adverse effect on the circuit board, and it is easy to destroy the circuit due to excessive temperature. Therefore, it is necessary to configure a certain heat dissipation mechanism for the display screen. The existing heat dissipation mechanism usually uses Usually, the heat can only be guided and discharged from the other side of the heat dissipation mechanism, causing the heat inside the heat dissipation mechanism to be too concentrated, thereby affecting the heat conduction efficiency and reducing the heat dissipation effect on the display screen.
