The invention discloses an LVDS (Low-Voltage Differential Signaling) screen control method based on a Shenwei notebook computer, relating to the technical field of computers. The LVDS screen control method comprises the following steps: initializing a graphics card by a BIOS (Basic Input/Output System) program; sending a function code and a command to an EC (Electronic Computer) through an LPC (Low Pin Count) bus; analyzing whether to turn on or turn off a screen after the EC receives the function code and the command, wherein the on/off the screen is controlled by the EC. According to the LVDS screen control method disclosed by the invention, the screen can be turned on according to a program by which the display time can be accurately mastered, so that the purpose of controlling on/off the LVDS screen is realized; the defect that some strange images are displayed on the screen because the turning-on time cannot be well mastered under a traditional mode is overcome, and the user experience of the Shenwei notebook computer is greatly improved.
