An electronic device is provided in this disclosure. The electronic device includes a display panel and a processor. The processor is electrically connected to the display panel. The processor receives image data and calculates a display area occupied by the image data on the display panel according to the image data. Then, the processor adjusts a backlight current value of the display panel according to the display area and an area-current relationship, to adjust the brightness of the display panel. In this way, the brightness of the display panel is consistent when the display panel displays images of different areas. The disclosure also provides a brightness adjustment method of an electronic device.
