[0001] The utility model relates to the technical field of backlight controllers, in particular to a dynamic backlight controller with rapid heat dissipation. Background Art

[0002] Liquid crystal display devices are widely used in electronic products such as televisions, mobile phones, and advertising machines due to their advantages of low radiation, low power consumption, and small size. Liquid crystal display devices usually include: a display panel, a backlight module for providing backlight to the display panel, and a backlight controller for controlling the light emission of the backlight module. In particular, when advertising machines are used outdoors, a corresponding dynamic backlight controller is required to adjust the brightness of the advertising machine display.

[0003] The current fast heat dissipation dynamic backlight controller will generate heat when in use. Excessive heat will affect the service life of the device. Moreover, when dissipating heat, a heat dissipation window is usually used, which causes the inner wall components to contact the outside world, which is not conducive to the protection of internal components. In view of the above problems, a fast heat dissipation dynamic backlight controller is proposed. Utility Model Content
