Embodiment 1

[0033] figure 1 The implementation flow of the display screen adjustment method under the EFI platform provided by the first embodiment of the present invention is shown, and the details are as follows:

[0034] In step S101, obtain the user's screen adjustment parameter generation information;

[0035] In step S102, generate information according to the user's screen adjustment parameters, and obtain corresponding screen adjustment parameters;

[0036] In the embodiment of the present invention, taking a low-voltage differential signaling (Low-Voltage Differential Signaling, LVDS) display device as an example, the specific screen adjustment parameters include:

[0037] Dot Clock (DCLK): The frequency displayed at each point is equivalent to providing a reference time for the screen display;

[0038] Horizontal active pixel (HA): the number of all pixels on the horizontal line;

[0039] Horizontal front porch(sync offset)(HFP): Horizontal synchronization compensation;

[0...

Embodiment 2

[0050] In the embodiment of the present invention, the screen adjustment parameter generation information can be the resolution specification parameter specified by the user, or the target resolution parameter specified by the user, for example, 852*48060Hz852480, indicating that the horizontal target resolution is 852, and the vertical target resolution 480 with a refresh rate of 60Hz.

Embodiment 3

[0052] As an embodiment of the present invention, commonly used resolution specification parameters and corresponding screen adjustment parameter lists are stored in the EFI firmware.

[0053]When the information generated by the user's screen adjustment parameters is the resolution specification parameter, search for the specified resolution specification parameter in the resolution specification parameter and the corresponding screen adjustment parameter list, and then obtain the corresponding screen adjustment parameter, and then adjust the screen according to the acquired Parameters modify the corresponding display screen adjustment parameter configuration information in VBIOS.

Abstract

The invention is suitable for the field of computers, and provides a method for adjusting a display screen under an extensible firmware interface (EFI) platform, a system and equipment. The method comprises the following steps of: acquiring the screen adjusting parameter generation information of a user; acquiring a corresponding screen adjusting parameter according to the screen adjusting parameter generation information; and modifying corresponding display screen adjusting parameter configuration information in a video basic input output system (VBIOS) according to the screen adjusting parameter. A screen adjusting driver is arranged under the EFI platform, so that the display screen adjusting parameter is customized to meet the customizing requirement of the user; meanwhile, the independence of a module is ensured, the module is conveniently transplanted to other platforms, more special display resolution specifications can be supported, the limit of an internal structure of the VBIOS is broken, the screen adjusting parameter can be dynamically customized, the special resolution of the user is customized, and great convenience is brought to development.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a display screen adjustment method, system and equipment under an EFI platform. Background technique [0002] The Extensible Firmware Interface (Extensible Firmware Interface, EFI) is an upgrade program introduced by Intel to replace the Basic Input Output System (BIOS) in future PC-like computer systems. EFI is a system built in the form of modularization, C-style parameter stack transfer, and dynamic linking. Compared with BIOS, it is easier to implement, has stronger error tolerance and error correction features, and shortens the time for system development. With the development of technology, EFI has been gradually applied to the motherboard industry, and as the second-generation BIOS, it is responsible for the platform power-on self-inspection. The initialization of EFI includes the configuration of the specified display device. [0003] At present, the industry mainly...
