Problems solved by technology

However, the above-mentioned techniques for adjusting the screen of the display device all adjust the overall screen of the display device, that is, if only a certain part of the display area (such as the area that the user focuses on) in the display screen needs to adjust the backlight while other display areas do not. When it is necessary to adjust the backlight, the above-mentioned usage requirements cannot be realized according to the traditional technology of adjusting the backlight

Embodiment Construction

[0017] figure 1 It is a schematic diagram of the first embodiment of the present invention. In this embodiment, the display device 2 of the present invention includes a display screen 25 , an image acquisition unit 21 , an analysis unit 22 and a control unit 24 . Wherein, the display screen 25 may be a liquid crystal display. The image capturing unit 21 (such as a web camera (Webcam) or other camera devices) is used to capture the environmental image 1 . The analysis unit 22 is used to analyze the environmental image 1 to generate environmental information 23 , wherein, preferably, the environmental information 23 includes the relative position of the user and the display screen 25 , or the relative position of the ambient light source and the display screen 25 . The control unit 24 is used for controlling the backlight of a part of the display screen 25 according to the environmental information 23 .

[0018] In this embodiment, if an obvious light source (such as a desk l...

Abstract

The invention discloses a computer system, a display device and a backlight control method. The use behavior (such as the position of the user) of a user and the environment variables (such as the position of an environment light source) are detected through the display device provided with an image acquisition system by using the judgment technique of computer vision so as to manage the power source of the display, and thus, the purpose of energy saving is achieved.

Description

technical field [0001] The present invention relates to a display device, a computer system and a backlight control method. In particular, it relates to a computer system, a display device and a backlight control method of the display device for adjusting different backlight sources inside and outside a specific area of ​​an overall screen of the display device. Background technique [0002] One of the methods currently on the market to make the display device operate in the power saving mode is to manually adjust the overall backlight of the liquid crystal display of a personal computer (such as a notebook computer). The backlight source and the overall backlight are adjusted according to the analysis of the content of the screen (such as brightness and darkness, contrast, histogram distribution, etc.), so as to achieve the power saving effect. However, when the power cord of the notebook computer is unplugged and powered by a pure battery, the existing adjustment method u...
