Abstract: Disclosed are a display device and a backlight control method for the display device. The display device includes a display panel, a backlight source, a first computing unit, and a second computing unit. The display panel includes a first display region and a second display region. The first light-emitting region corresponds to the first display region. The second light-emitting region corresponds to the second display region. The first computing unit calculates a first brightness distribution within a first range. The second computing unit calculates a second brightness distribution within a second range. The first light-emitting region emits light according to the first brightness distribution. The second light-emitting region emits light according to the second brightness distribution.

Abstract: The disclosure provides an electronic device and a diagnosis method of a light-emitting device. The light-emitting device includes at least one region, and each region of the at least one region has a plurality of light-emitting units. The diagnosis method includes the following steps. A plurality of light-emitting units of one of the at least one region are illuminated by a current. A voltage value corresponding to the current is compared with a first standard voltage value corresponding to a first standard current corresponding to the one of the at least one region. Whether the one of the at least one region is abnormal is determined according to a result of comparing the voltage value with the first standard voltage value. Therefore, the diagnosis method of the disclosure may effectively diagnose whether the at least one region of the light-emitting device is abnormal.
