The present disclosure provides an electronic display device including a backlight module, a light sensor, a storage device, an embedded controller, and a processing unit. The light sensor detects ambient light surrounding the electronic display device. The embedded controller controls intensity of the backlight module according to the ambient light and a brightness table of the storage device. The processing unit performs a basic input/output system to draw a brightness curve diagram according to the brightness table for users to adjust the curve of the brightness curve diagram during a boot process of the electronic display device and update the brightness table in the storage device according to the adjusted brightness curve diagram in response to a storing signal.

Electronic display device and backlight adjustment method thereof

A computer system and a control method thereof are provided, wherein the computer system comprises an embedded controller (EC), a basic input/output system (BIOS), and an operating system (OS). In the method, when the computer system is rotated, the EC makes the BIOS identify a present rotation state of the computer system by an interrupt signal and an internal communication scheme. Then, the BIOS establishes a data structure in accordance with a virtual scan code and the rotation state, and then transmits the data structure to the OS. After that, the OS controls a program installed in the computer system to execute a related operation of the rotation state according to the data structure.
