Description

Technical Field

[0001] The utility model relates to the field of display screen related products, in particular to an LCD screen with rapid heat dissipation. Background Art

[0002] Liquid crystal display, abbreviated as LCD in English, is a type of flat-panel display used for screen display of televisions and computers. The advantages of this display are low power consumption, small size and low radiation. Liquid crystal display (LCD) is a type of display used for digital clocks and many portable computers. LCD display uses two polarized materials with a liquid crystal solution between them. When electric current passes through the liquid, it rearranges the crystals so that light cannot pass through them. Therefore, each crystal acts like a shutter, which can both allow light to pass through and block light.

[0003] The existing LCD screen has insufficient heat dissipation function, which causes the screen to overheat and be damaged. In addition, the exhaust holes are not easy to clean, which can easily lead to blockage and affect the heat dissipation efficiency. Utility Model Content
