摘要： 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.

摘要： A backlight source includes light bars, adapter plate(s) and connection structures. Each light bar includes light-emitting group(s) and external connection unit(s). Each external connection unit is electrically connected to at least one light-emitting group and included at least one first electrode pair. Each adapter plate includes adapter circuits, each adapter circuit includes adapter units, each adapter unit includes at least one second electrode pair. Ends of each connection structure are electrically connected to one external connection unit and one adapter unit. All second electrode pairs of adapter units of a same adapter circuit are classified into at least one group, each group includes second electrode pairs electrically connected in series. In light-emitting groups electrically connected to adapter units of the same adapter circuit, light-emitting groups electrically connected second electrode pairs in a same group are connected in series to form a dimming region.
