Abstract
A backlight driving board includes a main circuit board, and a photosensitive device, a backlight controller and a first port that are disposed on the main circuit board. The photosensitive device is configured to sense brightness and color temperature of a light source, and output brightness data and color temperature data. The backlight controller is coupled to the photosensitive device, and configured to receive the brightness data and adjust light-emitting brightness of the light source according to the brightness data. The first port is coupled to the photosensitive device, and configured to be coupled to a system board, receive the color temperature data, and transmit the color temperature data to the system board, such that the system board adjusts color temperature of a picture displayed by a display panel according to the color temperature data.
