Embodiment Construction
[0039] figure 1 is a flow chart of the screen display power saving method according to the first embodiment of the present invention. Such as figure 1 As shown, in step S1, the screen is divided into at least two display areas, and the brightness of each display area is controlled separately by the display control module. Those skilled in the art know that the screen can be divided into multiple display areas, such as three, four, five, or even more, as required, and the brightness of each display area can be controlled by a different display control module. control. Those skilled in the art also know that one display control module can also be used to control each display area respectively. Those skilled in the art also know that the conventional display control module may include a group or one LED arranged on both sides, the center or any suitable position of the display area to illuminate the display area, and an LED driving circuit for driving the LED. Or LED driver c...

The invention relates to a screen display power-saving method and a device. The method comprises the steps: S1, a screen is divided into at least two display areas and the brightness of the display areas is respectively controlled by a display control module; S2, a user touch signal is received from the screen and then a first brightness control signal and a second brightness control signal are generated based on the position coordinate ranges of at least two display areas and the position coordinate range of the user touch signal; and S3, the display control module respectively controls the brightness of at least two display areas based on the first brightness control signal and the second brightness control signal. According to the screen display power-saving method and the device, the reduction of power consumption, the battery cruising ability of equipment using batteries as the power supply and the increasing of user experience can be realized by selectively displaying the brightness of the display areas of the screen.
Description
technical field [0001] The present invention relates to the field of screen display, and more specifically, to a method and device for power saving of screen display. Background technique [0002] As mobile terminal handheld devices become more and more popular, battery life has become an evaluation standard for mobile terminal handheld devices. The screen display of a mobile terminal device usually consumes a lot of power. For devices with larger screens, when swiping out a page, the user often does not browse the entire screen content in a short period of time. However, the mobile terminal handheld devices in the prior art are always displaying content that does not need to be browsed in time with the same brightness. Therefore, a large amount of electric energy is consumed, resulting in poor endurance of the battery. Contents of the invention [0003] The technical problem to be solved by the present invention is that, aiming at the defect that the screen display dev...
