Problems solved by technology

This screen saver method has some disadvantages, for example: when watching a movie, the keyboard and mouse may not be used for a long time, and the computer enters the screen saver without warning; or, when the user sets the startup time of the screen saver to If the setting is too long, but the user is not actually using the computer all the time, the computer cannot enter the screen saver mode for a long period of time, thus failing to achieve the effect of saving power and energy.

Embodiment Construction

[0011] refer to figure 1 Shown is an application environment diagram of a preferred embodiment of the screen display energy saving system 10 of the present invention. The screen display energy-saving system 10 is installed and operated in an electronic device, and the electronic device is connected with a camera 2 and a display screen 3 . In this embodiment, the electronic device is a computer 1 . In other embodiments, the electronic device may be a notebook computer (Notebook), a television, and other electronic devices with a display function. The camera 2 is used to capture images of the display screen 3 in a specified range in real time, and transmit the images to the computer 1 . For example, it is specified that the images captured by the camera 2 within 60 cm from the front of the display screen 3 and within the range of -60 degrees to +60 degrees from the vertical direction of the display screen 3 are valid images.

Abstract

The invention provides an energy saving system and a method for screen display. The method comprises the following steps: setting and initializing a counter; starting a camera to obtain the images inthe specified range in front of the display screen; judging whether the human eyes watch the display screen; if yes, selecting the normal display mode for the display screen; if no, adding 1 second tothe counter every 1 second and detecting the counter in real time, if the counter is less than the first preset time, selecting the normal display mode for the display screen; if the counter is morethan or equal to the first preset time but less than the second preset time, selecting the screen saver mode for the display screen; if the counter is more than or equal to the second preset time, selecting the energy saving mode for the display screen and automatically turning off the display screen. Being implemented, the invention can enable the display screen to be in the energy saving state in real time by tracking the positions of the human eyes.

Description

technical field [0001] The invention relates to a system and method for controlling screen display, in particular to a screen display energy-saving system and method. Background technique [0002] People all over the world are advocating the importance of energy saving, so more and more electronic products try to incorporate the concept of energy saving in their design. For example, the computer screen saver is designed to save power and energy. However, the startup method of the general computer screen saver is based on the detection of the waiting time of the keyboard and mouse, and usually takes minutes as the unit. . This screen saver method has some disadvantages, for example: when watching a movie, the keyboard and mouse may not be used for a long time, and the computer enters the screen saver without warning; or, when the user sets the startup time of the screen saver to If the setting is too long, but the user is not actually using the computer all the time, the co...
