Problems solved by technology

However, depending on the place where the screen is used, the brightness of the surrounding environment is also different, and the surrounding environment also changes with the change of day, night and weather, resulting in a change in the brightness of the surrounding environment
In the case of changing ambient brightness, the screen always maintains the same high brightness, which not only does not save energy, but also affects the user's visual experience, and no one is in front of the display screen, the display screen is still displayed at high brightness, wasting power and shortening the display. screen life

Embodiment 1

[0028] see figure 1 , is a flowchart of an embodiment of a screen energy-saving display method according to the present invention. Such as figure 1 As shown, the screen energy-saving display method of this embodiment specifically includes the following steps:

[0029] Step S101, collecting ambient light intensity, and converting it into a digital signal by preprocessing;

[0030] Step S102, judge the ambient light intensity interval to which the ambient light intensity belongs through the digital signal; wherein, the ambient light intensity interval is preset, and each interval has a certain range, which can be set according to the actual application;

[0031] Step S103, query the preset correspondence table between the ambient light intensity interval and the pulse width modulation signal according to the ambient light intensity interval to determine the output pulse width modulation signal;

[0032] Step S104, controlling the brightness output of the screen through the pu...

Embodiment 2

[0040] On the basis of Embodiment 1, this embodiment also uses whether there is a person in front of the screen as an influencing factor to adjust the brightness of the screen. Such as image 3 Shown is the specific flow chart of this embodiment. The screen energy-saving display method in this embodiment specifically includes the following steps:

[0041] Step S201, collecting ambient light intensity, and performing preprocessing to convert it into a digital signal;

[0042] Step S202, judge the ambient light intensity interval to which the ambient light intensity belongs through the digital signal; wherein, the ambient light intensity interval is preset, and each interval has a certain range, which can be set according to the actual application;

[0043]Step S203, detecting whether someone is in front of the screen, and if there is, automatically move the currently detected ambient light intensity interval to the next larger ambient light intensity interval, and use the lar...

Abstract

The invention relates to the field of screen display, in particular to a screen energy-saving display method and a screen energy-saving display device. The screen energy-saving display method includes steps of acquiring ambient light intensity, preprocessing the ambient light intensity into digital signals; judging an ambient light intensity area which the ambient light intensity belongs to by the aid of the digital signals; inquiring a preset corresponding table of the ambient light intensity area and pulse width modulation signals according to the belonging ambient light intensity area, determining outputted pulse width modulation signals, and controlling luminance output of a screen by the aid of the pulse width modulation signals. The ambient light intensity corresponds to the pulse width modulation signals, the corresponding pulse width modulation signal is inquired by acquiring the ambient light intensity, and the luminance of the screen is controlled through the pulse width modulation signals, so that the luminance of the screen can be adjusted automatically according to different environments, waste of electric energy is reduced, the screen is avoided from keeping at high luminance for long time, and the service life of the screen is prolonged.

Description

technical field [0001] The invention relates to the field of screen display, in particular to a screen energy-saving display method and device. Background technique [0002] Existing display screens are widely used in various places, such as outdoor advertising screens, indoor dispatching display screens, welcome display screens, conference display screens, and the like. However, depending on the place where the screen is used, the brightness of the surrounding environment is also different, and the surrounding environment also changes with changes in day, night and weather, resulting in a change in the brightness of the surrounding environment. In the case of changing ambient brightness, the screen remains at the same high brightness, which not only does not save energy, but also affects the user's visual experience, and the display is still displayed at high brightness when no one is in front of the display screen, which wastes power and shortens the display. The lifespan...
