METHOD FOR ADJUSTING DISPLAY BACKLIGHT WITH AID OF AMBIENT LIGHT BRIGHTNESS DETECTION AND TIME DETECTION, AND ASSOCIATED APPARATUS AND ASSOCIATED COMPUTER PROGRAM PRODUCT

摘要

A method and apparatus for adjusting display backlight and an associated computer program product are provided. The method is applied to an electronic device. The method includes the steps of: utilizing at least one light sensor of the electronic device to detect ambient light; and performing a plurality of detection operations to selectively control the electronic device to enter a specific mode to adjust brightness level of a backlight module of a display panel of the electronic device. The detection operations includes: detecting whether the ambient light is less than a predetermined ambient brightness threshold value for a time period; and detecting whether a length of the time period reaches a predetermined time threshold value. For example, the specific mode can be a low-light mode, which is suitable for a user who has stayed in the dark for a time period (e.g. tens of minutes, or one or more hours).

主权项

1. A method for adjusting display backlight, the method being applied to an electronic device, the method comprising the steps of:
utilizing at least one light sensor of the electronic device to detect ambient light brightness; and controlling a brightness level of a backlight module of a display panel of the electronic device to automatically switch to be one of a plurality of predetermined levels of an automatic backlight mode in response to the ambient light brightness before the electronic device enters a specific mode, and performing a plurality of detection operations to selectively control the electronic device to enter the specific mode to adjust the brightness level of the backlight module of the display panel of the electronic device, wherein the plurality of detection operations comprises:
detecting whether the ambient light brightness is less than a predetermined ambient brightness threshold value for a time period; anddetecting whether a length of the time period reaches a predetermined time threshold value.
