Abstract: An electronic device is provided, including a display panel and a processor. The display panel is configured to display image data and includes a backlight module, and the processor is electrically connected to the display panel. The processor averages current values of the backlight module corresponding to the image data in a first time period, to generate an average current value, and compares the average current value with a current threshold. When the average current value is greater than the current threshold, the processor generates an adjusted maximum current value, and correspondingly reduces current values of the backlight module in a second time period according to the adjusted maximum current value, to reduce a temperature of the electronic device. A temperature adjustment method of an electronic device is also provided.

Abstract: 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.

Abstract: An electronic device is provided, including a display panel and a processor. The processor is coupled to the display panel, and is configured to calculate an average temperature of the display panel, where when the average temperature is greater than a first temperature threshold, the processor adjusts an upper brightness limit of the display panel to a first adjusted maximum brightness value, so that brightness of the display panel is not greater than the first adjusted maximum brightness value. The disclosure further provides a display panel control method for an electronic device.
