Problems solved by technology

[0002] At present, with the widespread application of smart phones, mobile phone display technology has gradually become a research hotspot; in the current mobile phone display field, there are not only single-display mobile phones, but also dual-screen mobile phones or even multi-screen mobile phones; Or mobile phones with more than two display screens, the screen brightness of each display screen is usually inconsistent. The brightness of the backlight is different; however, end users generally have the same requirements for the brightness of the backlight of each display screen, so the above-mentioned control scheme for the brightness of the display screen backlight cannot meet the needs of users

[0051]The first embodiment of the present invention describes a method for controlling the backlight brightness of a display screen of an electronic device. The electronic device may include N display screens connected to each other through connecting components, where N is a natural number greater than 1;

[0052] Obviously, when N is equal to 2, the electronic device can be a dual-screen electronic device, and when N is greater than 2, the electronic device is an electronic device with more than two display screens; that is, the embodiment of the present invention is not only suitable for dual-screen electronic devices , and is suitable for electronic devices with more than two displays.

[0053] figure 2 This is the flow of the method for controlling the backlight brightness of the display screen of the electronic device according to the embodiment of the present invention Figure 1 ,like figure 2 shown, the process can include:

[0054] Step 201: Determine the display...

[0087] In order to better reflect the purpose of the present invention, further examples are given based on the first embodiment of the present invention.

[0088] In the second embodiment of the present invention, a dual-screen electronic device is taken as an example to describe the implementation of the method for controlling the backlight brightness of the display screen.

[0089] image 3 It is a schematic structural diagram for realizing the backlight brightness control of the display screen of the dual-screen electronic device in the embodiment of the present invention, such as image 3 As shown in the figure, the two display screens of the dual-screen electronic device are recorded as the main screen and the secondary screen, respectively. image 3 The shown structure may include a main screen driver chip 301, a sub screen driver chip 302, a main screen backlight chip 303, a sub screen backlight chip 304, a first LED backlight 305 and a second LED backlight 306; where...

no. 3 example

[0108] In the third embodiment of the present invention, the display content of each display screen may be determined first; then, the type of the display content of each display screen may be determined; when the type of the display content of at least two of the N display screens is different At the same time, different CABC modes are used to control the backlight brightness for display screens displaying different types of display contents.

[0109] Here, the display content type of the display screen may include a UI interface, a static image, a dynamic image, and the like.

[0110] The implementation manner of the third embodiment of the present invention is exemplarily described below by taking the above-mentioned dual-screen electronic device as an example.

[0111] In an example, for different application scenarios, different CABC values ​​can be used when the display content types of the main screen and the secondary screen of the dual-screen electronic device are dif...

Abstract

An embodiment of the present invention provides a method for controlling the brightness of a display screen of an electronic device. The electronic device includes N display screens; the method includes: determining the display content of each display screen; according to the display content of each display screen, and determining Display the backlight brightness of each display screen; when there are at least two display screens with different backlight brightness among the N display screens, adjust the backlight brightness of at least one of the N display screens so that the backlight brightness of the N display screens Brightness is the same. The embodiment of the invention also discloses an electronic device and a computer-readable storage medium.

Description

technical field [0001] The present invention relates to a multi-screen display technology, and in particular, to a method for controlling the backlight brightness of a display screen of an electronic device, an electronic device and a computer-readable storage medium. Background technique [0002] At present, with the wide application of smart phones, mobile phone display technology has gradually become a research hotspot; in the current mobile phone display field, there are not only single-display mobile phones, but also dual-screen mobile phones and even multi-screen mobile phones; For mobile phones with more than two display screens, the screen brightness of each display screen is usually inconsistent. For example, when each display screen displays different content, each display screen usually adopts a different screen brightness determination method, which may lead to different display screen brightness. The backlight brightness is different; however, the end user's req...
