Embodiment Construction

[0011] figure 1 It is a schematic diagram of the hardware structure of an electronic device for adjusting the brightness of the backlight in the present invention. An electronic device for adjusting backlight brightness (hereinafter referred to as "electronic device") 1 includes a light sensor 10 , a distance sensor 20 , a control unit 30 , a storage unit 40 , a backlight unit 50 and a display unit 60 . The light sensor 10 is used for sensing the ambient light around the electronic device 1 in real time and generating an illuminance signal of the ambient light. The distance sensor 20 is used to sense an object within a predetermined range from the electronic device 1 in real time, and generate a sensing signal when sensing an object within the predetermined range. The storage unit 40 stores a backlight parameter table 42, and the backlight parameter table 42 stores correspondences between various ambient lights and backlight parameters. For example, the illuminance of an amb...

Abstract

The invention provides an electronic device and method for adjusting the backlight brightness. The method comprises the following steps of: sensing and detecting the change of ambient light in real time; when the weakening of the ambient light is detected, judging whether an object in a preset range is sensed or not; and when the object in the preset range is sensed, stopping the adjustment of the backlight of the electronic device. Whether the weakening of the ambient light is caused by the shielding of the object close to the electronic device is judged or not, if so, the electronic device does not adjust the backlight brightness of the display unit of the electronic device, and if not, the backlight brightness of the display unit of the electronic device is increased, and thus the accurate adjustment is achieved and the comfortableness is brought to users.

Description

technical field [0001] The present invention relates to an electronic device, more particularly, to an electronic device for adjusting the brightness of a backlight and a method for adjusting the brightness of the backlight. Background technique [0002] Currently, electronic devices with display panels, such as mobile phones and tablet computers, adjust the brightness of the backlight of the display panel according to sensing ambient light, so that users can see the display screen clearly in different environments. However, when an object is close to the electronic device, such as the user's hand, face, etc., the object is likely to block the ambient light, so that the electronic device is prone to misjudgment. For example, when an object blocks the ambient light of the electronic device to make its light weaker, the electronic device increases the brightness of its backlight correspondingly according to the weakened ambient light, but the ambient light of the electronic de...
