Embodiment Construction

[0015] In order to make the purpose, technical features and implementation effects of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The display is the main window and means of human-computer interaction, and its purpose is to display content; and the user's eyes are the main way for the user to obtain information. This proposal uses the human eye sight detection technology to realize energy saving on the display screen that can be controlled by area.

[0016] Such as figure 1 As shown, the display specifically includes:

[0017] The human eye sight detection unit 101 is configured to acquire an image of the human eye sight and convert the human eye sight parameter for transmission.

[0018] Since the human eye sight direction detection technology is a relatively new and existing detection technology, in the application of the present inven...

Abstract

The invention provides an energy-saving display and electronic equipment. The energy-saving display comprises a first display screen, a human eye sight line detection unit, a first data processing unit and a first display control unit. The first display screen is used for displaying outputted information; the human eye sight line detection unit is used for intercepting the human eye sight line image information and calculating the human eye sight line parameters from the human eye sight line image information with a preset algorithm; the first data processing unit is used for calculating the first coordinate of the human eye sight line in the first region of the first display screen and the second coordinate of the human eye sight line in the second region of the first display screen and using the first coordinate and the second coordinate as display control parameters; the first display control unit is used for generating energy-saving electrical signals according to the display control parameters so as to control the power consumption of the first display screen. The embodiment of the invention has the advantages that the energy-saving mode suitable for the user is selected by the user, and the human eye sight line detection technology is fully used, thus the energy-saving display can save energy in an adaptive way without affecting the energy-saving display using experienceof the user.

Description

technical field [0001] The invention relates to energy-saving technology for electronic equipment, in particular to an energy-saving display and electronic equipment. Background technique [0002] The display unit is an important power consumption unit of electronic devices such as portable electronic devices and smart handheld devices, and its power consumption accounts for about half of the total power consumption of the entire electronic device. The power consumption of the display unit is closely related to the display color, resolution, and display area. In the liquid crystal display, the power consumption of the backlight is also one of the components that consume more power. If the power consumption of the display can be reduced, the battery life of the portable device can be greatly improved and power can be saved. [0003] The purpose of the display is to display the required content, and it is the main window and means of human-computer interaction. Eyes are the ...
