ELECTRONIC APPARATUS AND METHOD FOR CONTROLLING BRIGHTNESS FOR A DISPLAY

摘要

An electronic apparatus including a display, a light sensor and a controller is provided. The display displays an image. The light sensor measures the ambient brightness received by the display. The controller is coupled to the display and the light sensor. The hardware brightness range of the display is divided into a plurality of segments, wherein the first segment includes the hardware lowest brightness of the display and the last segment includes the hardware highest brightness of the display. The controller limits the display brightness of the display to one of the segments according to the ambient brightness. The controller allows the user of the electronic apparatus to set the display brightness only when the display brightness is limited to the first segment.
