Heat Dissipation Of LED Backlight Devices

  Backlight screen printing display comprehensive use of imported large integrated circuits, reliability greatly improved, easy to debug and maintain static scanning technology using static locking scanning mode, high-power drive, fully guarantee the luminous brightness image screen clear, no chatter and ghosting backlight screen printing display, backlight screen printing display can choose a series of resolution, and can be adjusted according to the screen requirements, but the backlight screen only contains a fixed The number of LCD units, the full screen can only use a resolution display (each unit is a pixel) backlight screen printing display with dust also requires more attention.

  Working in a dusty environment, due to PCB adsorption of dust, and dust deposition will affect the heat dissipation of electronic components, will lead to component temperature rise, and then thermal stability decline to produce leakage, and in serious cases will lead to burnout. Therefore, care should be taken to keep the backlight display environment clean.CRT usually has three electron guns, and the injected electron flow must be collected correctly. Otherwise, a clear image display cannot be obtained. However, the backlight has no focus because each LCD unit is individually switched on and off. This is exactly why the same picture is so clear on the backlight screen.
