Abstract

An embodiment of the invention provides a brightness adjusting device and method, relates to the technical field of display, and solves the problem of adverse effects on visual effects of pictures viewed by human eyes and human eye health due to fixed display brightness of a displayer. According to the embodiment, the brightness adjusting device comprises a signal acquisition unit, a data extraction unit, a data judging unit and an adjusting unit, wherein the signal acquisition unit is used for acquiring an ambient light brightness value and a picture displayed by the displayer, the data extraction unit is used for extracting a picture brightness value from the picture displayed by the displayer, the data judging unit is used for searching a corresponding to-be-displayed brightness value from a preset brightness database according to the ambient light brightness value and the picture brightness value, and the adjusting unit is used for adjusting the brightness of the displayer according to the to-be-displayed brightness value. The brightness adjusting device and method are mainly applied to occasions where the displayers are required, such as official business handling, entertainment, communication and the like.

Description

technical field [0001] The invention relates to display technology, in particular to a brightness adjustment device and method. Background technique [0002] With the maturity and popularization of display technologies such as computers and mobile phones, especially the increasing dependence on computers in daily office work, the ensuing problem is that the damage of displays to people's eyes is becoming more and more obvious. Especially when the light intensity of the surrounding environment changes, but the brightness of the display remains unchanged, the human eyes will feel very uncomfortable; in addition, when people face the display with the same brightness for a long time, they will also experience visual fatigue, which is very harmful to the health of the eyes. [0003] Existing displays generally use a uniform backlight when displaying, and do not analyze changes in the light intensity of the surrounding environment and the needs of the human eye to dynamically chan...
