Problems solved by technology

While it brings rich colors to people, it is also quietly hurting people's eyes. Too bright a display screen often makes people feel uncomfortable. On the one hand, it is easy to cause visual fatigue, and it also reduces the contrast between pure black and pure white. Affects the performance of color scale and gray scale
Excessively bright computer monitors hurt the human eye while wasting a lot of power

Embodiment 1

[0023] Such as figure 1 Shown, a kind of computer energy-saving monitor comprises:

[0024] a distance measurement module, configured to measure the distance between the user and the display;

[0025] The brightness setting module is connected with the distance measuring module, and is used to set the display to be dark and bright according to the measured distance; for example, a standard distance, a relatively short distance, a relatively short distance, etc. Set the corresponding display brightness according to different distance ranges;

[0026] The display module is connected with the brightness setting module, and is used for displaying according to the set brightness of the display.

[0027] Wherein, it also includes a display closing module connected to the brightness setting module, a counting module is arranged in the brightness setting module, and the distance measuring module regularly measures the distance between the user and the display, and when the measured ...

Embodiment 2

[0030] Such as figure 1 As shown, a computer energy-saving monitor display method, comprising:

[0031] 1) distance measuring step, measuring the distance between the user and the display;

[0032] 2) The brightness setting step is to set the display to be dark and bright according to the measured distance;

[0033] 3) The display step is to display according to the set brightness of the display.

[0034] Wherein, said step 2) also includes the step of turning off the display, regularly measuring the distance between the user and the display, and when the measured distance between the user and the display exceeds the set range, counting the number of times of determination beyond the set range, when continuous When the accumulated count value exceeds a set threshold, the count value is cleared and the display is turned off.

[0035] Among them, when counting the number of times of measurement that exceeds the set range and the continuously accumulated count value does not e...

Abstract

The invention provides a computer energy-saving display and a method thereof, wherein, the computer energy-saving display comprises a distance measuring module for measuring the distance between the display and a user, a luminance setting module connected with the distance measuring module for setting luminance of the display according to the measured distance, and a display module connected withthe luminance setting module for displaying according to the set luminance of the display. In the invention, as the computer display is internally provided with the distance measuring module, the display is brightest when the distance between a human body and the computer display is within a correct sitting posture range of 50-70cm; and the closer the human body gets to the display, the darker thedisplay is; and the display is automatically closed when the human body gets away, thus achieving the purpose of saving electric energy and protecting eyes of people from being damaged by hard light,reminding the people of working with a correct sitting posture so as to reduce occupational diseases, and realizing less electric energy consumption and good protection on the eyes of people.

Description

technical field [0001] The invention belongs to the technical field of computer displays, in particular to an energy-saving display and an energy-saving display method thereof. Background technique [0002] With the popularity of the Internet and computers, people rely more and more on computers. Many people work at desks in front of computers all day long and are addicted to the Internet world. While computers bring various conveniences to people, they also bring troubles. Engaging in computer work for a long time will have many adverse effects on health and longevity, and the eyes are the first to bear the brunt. [0003] Excessive brightness of computer monitors will hurt people's eyes. Brightness refers to the brightness of the screen. The unit is candela per square meter (cd / m2) or lumen (nit), which is one candela per square meter. While it brings rich colors to people, it is also quietly hurting people's eyes. Too bright a display screen often makes people feel uncom...
