Problems solved by technology

Usually, when a user uses an electronic device, he will be close to the top of the display panel. At the same time, the user's hand or other objects may be located on the side or back of the electronic device, that is, the user or other objects block the ambient light of the display panel, resulting in electronic The ambient light of the device is dimmed, however, the electronic device does not adjust the brightness of the display panel, which can easily cause glare and discomfort to the user

Embodiment Construction

[0011] figure 1 It is a schematic diagram of the hardware structure of an electronic device for adjusting the brightness of the display screen in the present invention. The electronic device 1 defines a normal display mode and a dark display mode. The electronic device 1 includes a first light sensor 10 , a second light sensor 20 , a control unit 30 , a storage unit 40 , a backlight unit 50 and a display screen 60 . The first light sensor 10 is located on the display surface, that is, the front of the display screen 60 , and is used to sense the ambient light around it in real time. That is, the first light sensor 10 senses the ambient light on the front of the display screen 60 . The second light sensor 20 is located on the back or side of the electronic device 1 relative to the display surface, and is used for real-time sensing of ambient light around it. That is, the second light sensor 20 senses the ambient light on the back or side of the display screen 60 .

Abstract

The invention provides an electronic device and a method for adjusting the brightness of a display screen thereof. The front and back display faces or the front and side display faces of the electronic device are provided with light sensors respectively; whether adjusting of the brightness of the display screen is needed or not is judged according to judgment of the environmental light intensities sensed by using the two light sensors on the front and back faces or on the front and side faces; when the environmental light intensities sensed by using the two light sensors are both less than corresponding preset values, the electronic device is used for adjusting the brightness of the display screen of the electronic device or adjusting a background color and a font color in the display screen, so that more accurate adjustment is realized, and a user feels comfortable; otherwise, the brightness of the display screen is not adjusted through the electronic device.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly, to an electronic device and a method for adjusting brightness of a display screen thereof. Background technique [0002] Currently, electronic devices with display panels, such as mobile phones and tablet computers, adjust the brightness of the display panel according to sensing ambient light, so that users can see the display clearly in different environments. Usually, when a user uses an electronic device, he will be close to the top of the display panel. At the same time, the user's hand or other objects may be located on the side or back of the electronic device, that is, the user or other objects block the ambient light of the display panel, resulting in electronic The ambient light of the device is dimmed, however, the electronic device does not adjust the brightness of the display panel, which can easily cause glare and discomfort to the user.
