The disclosure provides a backlight driving board, a backlight module and a display device, which relate to the field of display technology and are intended to solve the problem that the display effect is affected by the attenuation of the brightness and color temperature of the backlight source in the display device. The backlight driving board includes: a main circuit board, a photosensitive device, a backlight controller and a first port. The photosensitive device is arranged on the main circuit board and is configured to sense the brightness and color temperature of the light source in real time, and output brightness data and color temperature data. The backlight controller is arranged on the main circuit board and coupled with the photosensitive device; the backlight controller is configured to receive the brightness data, and adjust the light emitting brightness of the light source according to the brightness data. The first port is set on the main circuit board and is coupled with the photosensitive device; the first port is configured to be coupled with the system mainboard, receive color temperature data, and transmit the color temperature data to the system mainboard, so that the system mainboard adjusts the color temperature according to the color temperature data Displays the color temperature of the picture displayed on the panel. The above-mentioned backlight driving board is used in a backlight module and a display device.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular to a backlight driving board, a backlight module, a display device and a method for adjusting brightness and color temperature thereof. Background technique [0002] After a long period of use of the liquid crystal display device (generally more than 30,000 hours), the brightness and color temperature of the light source in the backlight module will attenuate to a certain extent, making the picture displayed by the display device appear dark and yellowish. However, there is no monitoring and feedback mechanism for the light source in the liquid crystal display device, so that the light source and the display screen cannot be adjusted, and the display effect of the display device will become worse and worse with the increase of use time. Contents of the invention [0003] The disclosure provides a backlight driver board, a backlight module, a display device and a meth...
