Patent number: 12112712Abstract: 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.Type: GrantFiled: April 8, 2021Date of Patent: October 8, 2024Assignees: BEIJING BOE DISPLAY TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Lijin Zhao, Yu Zhang, Shixin Geng, Guangyun Tong, Zhuolong Li, Miao Liu, Huiyan Li, Fan Yang
