Abstract
The present disclosure relates to a display device including a display circuit, a sensor, a light control circuit and a processing circuit. The display unit includes a first display unit and a second display unit adjacent to the first display unit. The sensor obtains a first brightness value of the first display unit and a second brightness value of the second display unit. The light control circuit adjusts the light transmittance of multiple light control units of the light control circuit. The processing circuit calculates a brightness difference ratio value according to the first brightness value and the second brightness value. When the brightness difference ratio value is greater than a threshold value, the processing circuit adjusts a light control signal to change the light transmittance corresponding to the position of the second display unit.
