Problems solved by technology

[0004] Before the window operating system Windows8 appeared, the brightness of the display was controlled by the pulse width modulation signal output by the embedded controller, so the above-mentioned function of adjusting the brightness could be achieved, but under the framework of Windows8, the brightness of the display is limited. The window operation system is controlled by the display driver model (Windows Display Driver Model, WDDM), that is to say, the brightness of the display is controlled by the driver control platform control hub (Platform Controller Hub, PCH) output pulse width modulation of the window operation system display driver model. Signal to control the brightness, so it is impossible to adjust the brightness of the display in the traditional way under high temperature, low temperature or heavy load to achieve the purpose of making the computer work normally

Abstract

Disclosed are a brightness control device and a brightness control method. By the aid of a basic input / output unit, a chip or an embedded controller controls brightness of a display according to environmental conditions or an adjusting decision of a user, thus the needs of a user for adjusting are met or normal running of an electronic device is ensured.

Description

【Technical field】 [0001] The present invention relates to a control device, and in particular to a brightness control device and a brightness control method. 【Background technique】 [0002] Computers can be divided into military-grade computers and general computers. The difference between military-grade computers and general computers is that military-grade computers are often used in harsh environments, such as high-temperature or low-temperature harsh environments. Therefore, military-grade computers The demand for the ability to adapt to the ambient temperature is much greater than that of general computers, and factors such as lightness, lightness and small size that general computers care about are not the main considerations for military-standard computers. [0003] When a military-grade computer operates in a severe environment such as high temperature or low temperature, sometimes it is necessary to control the brightness of the display so that the military-grade co...
