Embodiment 1

[0071] combine figure 1 Embodiment 1 of the present invention is described in detail. Such as figure 1 As shown, the method for controlling the brightness of a display screen provided by Embodiment 1 of the present invention includes the following steps:

[0072] S11. Determine whether the display screen is in the screen display state:

[0073] It is judged whether the display screen is in the screen display state, if yes, execute step S12, if no, end the process.

[0074] It should be noted that the screen display in the embodiment of the present invention may be a display of pictures such as photos, such as different advertisement screens displayed on an advertisement display screen.

[0075] The above-mentioned picture may also be a video picture displayed when the video is played. When the display screen is playing video, it is considered that the display screen is in the screen display state.

[0076] S12. Acquiring brightness corresponding to the display screen:

Embodiment 2

[0099] The method for controlling the brightness of the display screen described in Embodiment 2 has many similarities with the control method described in Embodiment 1. For the sake of brevity, this embodiment only focuses on the differences. For the similarities, please refer to Description of Embodiment 1.

[0100] Such as image 3 As shown, the method for controlling the brightness of the display screen described in Embodiment 2 includes the following steps:

[0101] Steps S31 to S33 are the same as steps S11 to S13 in Embodiment 1. For details, please refer to the description of Embodiment 1.

[0102] S34. Judging whether the display screen exits the screen display state:

[0103] It is judged whether the display screen exits the screen display state, if yes, execute step S35, if no, the process ends.

[0104] S35, judging whether the current brightness of the display screen is the brightness set by the system:

[0105] It is judged whether the current brightness of t...

Embodiment 3

[0110] In the method for controlling the brightness of the display screen described in the third embodiment, it is judged whether to adjust the brightness of the display screen according to the brightness of a plurality of consecutive display images. Therefore, compared with the first and second embodiments, the control method described in the third embodiment reduces the number of adjustments of the brightness of the display screen, thereby overcoming the defect of excessive energy consumption due to too many adjustment times.

[0111] see Figure 4 , Figure 4 It is a schematic flowchart of the method for controlling the brightness of the display screen described in the third embodiment of the present invention. Such as Figure 4 As shown, the control method includes the following steps:

[0112] S41. Determine whether the display screen is in the screen display state:

[0113] It is judged whether the display screen is in the screen display state, if yes, execute step S...

Abstract

The invention provides a display screen brightness control method and control device. The control method comprises judging whether a display screen is in the image display state; if so, obtaining the brightness corresponding to the display image; and adjusting the brightness of the display screen according to the brightness of the display image. Since the brightness of the display image has an influence on the brightness of the display screen, when the display image is in bright face, the brightness of the display screen also improves; and therefore, under the condition of not influencing the normal display effect, the brightness of the display screen can be reduced; and with the display screen brightness control method based on the brightness of the display image, the electric quantity consumed due to the display of the display screen can be reduced favorably under the condition of not influencing the normal use.

Description

technical field [0001] The invention relates to the field of display control of display screens, in particular to a method and device for controlling the brightness of a display screen. Background technique [0002] With the development of science and technology, display devices with display screens have become an indispensable part of people's lives. These devices with display screens include mobile phones, televisions, computers, and more. [0003] These display devices consume a large amount of power when displaying. In order to save power, existing display screens can automatically adjust the brightness of the display screen according to the brightness of the external environment. When the brightness of the external environment is high, the display screen adopts a larger brightness, and when the brightness of the external environment is small, the display screen adopts a smaller brightness. [0004] However, this method does not take into account the influence of the b...
