Luminance real-time adjustment display screen system and luminance real-time adjustment method

Abstract

The invention discloses a luminance real-time adjustment display screen system, comprising a display screen, a single-chip microcomputer module, a human body sensing module, a brightness acquisition module, a brightness adjustment module, a button module, an indicator lamp and a Bluetooth module. The single-chip microcomputer module also includes a processor module, a storage module and a timing module. The storage module is used to store the brightness control curve, the human body sensing module is used to detect whether the user is located in the display area of the display screen, the timing module is used to obtain the actual duration of the user's use of the display screen, the brightness acquisition module collects the brightness value of the external environment, the brightness adjustment module adjusts the output brightness of the display screen, the button module and the indicator lamp are used to select the desired brightness control curve gear, and the Bluetooth module is used to implement human-computer interaction. The invention also discloses a brightness real-time adjustment method, which adjusts the brightness value output by the display screen in real time, so that the user's visual fatigue degree remains the lowest state during long-term use.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a real-time brightness adjustment display screen system and a real-time brightness adjustment method thereof. Background technique [0002] When the human eye performs visual work, the visual function will be affected to a certain extent, which is mainly manifested in the deepening of visual fatigue, damage to the fundus and increased mental load. Among them, the accumulation of visual fatigue in the process of operation will reduce the visual function of human eyes, which seriously threatens the health and safety of human eyes. In order to protect human eye health, it is necessary to select a suitable lighting environment, which requires people to evaluate different lighting environments. [0003] People's evaluation of the lighting environment mainly depends on the subjective perception of the user when performing visual operations in this lighting environment. Users evaluate t...

Problems solved by technology

[0005] 2. Different people have different constitutions, experiences, and tolerance levels, so the definition of comfort will be quite different, which makes the subjective scoring results change irregularly

[0006] Therefore, the limitations of the fatigue degree evaluation method limit the development of display products in the direction of health
