Embodiment Construction

[0024] A method for adaptively adjusting the brightness of a computer display screen:

[0025] Two-way illuminance sensors are used to obtain the current ambient light intensity data. After internal AD conversion, the data is transmitted to the FPGA control module, so that it can map the LED backlight brightness level at this time through the ambient light intensity, and select the target brightness suitable for human eyes. According to the current brightness of the display screen, it is judged whether the target brightness is consistent with the current brightness, and the corresponding duty cycle of the PWM signal driving the LED backlight is determined, and then the backlight circuit is adjusted to complete the adjustment of the brightness of the LED backlight.

[0026] According to the above method and content of the invention, the present invention will be further described in conjunction with the accompanying drawings.

[0027] At the same time, the present invention als...

Abstract

The invention discloses a computer display screen brightness adaptive adjustment method and belongs to the screen display technical field. According to the method, two illuminance sensors are adopted to detect current ambient light intensity; the level of LED backlight brightness is obtained through mapping based on the ambient light intensity; and a PWM duty ratio requiring adjustment is determined according to the actual brightness of a liquid crystal display, so that the LED backlight brightness can be changed, and therefore, the brightness of the display screen can be changed. With the method adopted, the problem of discomfort of eyes caused by the liquid crystal display in dramatic change of ambient light can be solved, and visual fatigue of the eyes can be relieved.

Description

technical field [0001] The invention discloses a method for adaptively adjusting the brightness of a computer display screen, which belongs to the technical field of screen display. Background technique [0002] Displays are input and output devices. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. It mainly refers to the display screen. With the development of science and technology, the current display screen has the characteristics of ultra-thin, energy-saving, high-quality image, etc., which is more conducive to protecting people's eyes. However, in the actual use process, when the ambient light intensity occurs When the drastic changes are inconsistent with the brightness of the display screen, the human eyes will still experience visual fatigue, and being in this environment for a long time will easily cause irreversible damage to human vision. In addition, too low...
