Problems solved by technology

[0005] However, the brightness automatically adjusted by the sensor is often not suitable due to different user habits
If user A is accustomed to using a certain brightness under a certain lighting level, and user B is accustomed to using another brightness under this lighting level, the manufacturer cannot correspond to a variety of automatically adjusted brightness under the same lighting level to meet the needs of different users

Embodiment Construction

[0019] The display device brightness control system and method can be widely used in various devices with display devices, such as notebook computers, mobile phones, personal digital assistants, desktop computers, and televisions.

[0020] see figure 1 , which is a frame diagram of a display device brightness control system. The display device brightness control system 100 includes a sensor 110 , a keyboard 120 , an embedded controller 130 , a storage module 140 and a display device 150 .

[0021] The sensor 110 is a photosensitive sensor (such as a photoresistor, a photodiode, etc.), which generates a corresponding electrical signal according to the lighting level of the surrounding environment, and the electrical signal is converted into a digital signal after analog / digital conversion. The sensor 110 is connected with the embedded controller 130 to transmit the digital signal to the embedded controller 130 . The embedded controller 130 can recognize the lighting level of ...

Abstract

The invention is a display device brightness control method, comprising the steps of: a sensor obtains the current illumination grade; calling find unit to confirm corresponding brightness value to the current illumination grade; according to the brightness value, adjusting the brightness of the display device; judging whether an input device has an instruction to input; if yes, adjusting the current display device brightness according to the instruction; according to the adjusted brightness, adjusting the corresponding relation between illumination grade and brightness value in the find unit. As compared with the existing technique, it can automatically adjust device brightness so as not to conflict with brightness adjustment by the input device. And it also reveals a display device brightness control system.

Description

【Technical field】 [0001] The present invention relates to a display device control system and method, in particular to a display device brightness control system and method. 【Background technique】 [0002] Display devices have been widely used in various fields, such as CRT (Cathode-Ray Tube, cathode ray tube) display or LCD (Liquid Crystal Display, liquid crystal display) display of desktop computer, notebook computer, mobile phone, personal digital assistant (Personal Digital Assistant, LCD monitors of portable devices such as PDAs, CRT TVs, plasma TVs (Plasma TVs) and LCD TVs, etc. [0003] When the display device is in use, it often encounters changes in ambient lighting. For example, moving the display device from indoors to outdoors or turning on and off indoor lights will cause changes in the surrounding lighting of the display device. After the ambient lighting changes, if the display device still uses the original brightness, it may cause discomfort to the user's e...
