Embodiment 1
[0041] see figure 1 The method for driving a display screen provided by Embodiment 1 of the present invention includes the following steps:
[0042] S101. Before the display screen needs to be replaced, start the system normally;
[0043] S102, after the system starts successfully, start the application program and load the dynamic library;
[0044] The dynamic library provides driver and application interaction functions;
[0045] S103, the application program opens the node interface defined in the dynamic library;
[0046] S104. The application layer invokes the node interface and writes the parameters of the display screen to be replaced;
[0047] In Embodiment 1 of the present invention, the display screen parameters include display screen resolution, screen interface type, CLK, HBP, HFP, HPW, VBP, VFP, VPW, LVDSFORMAT, OUTFAC and other parameters.
[0048] In Embodiment 1 of the present invention, the writing of the parameters of the display screen to be replaced is ...
Embodiment 2
[0061] see figure 2 , the system for driving the display screen provided by Embodiment 2 of the present invention includes:
[0062] The start module 11 is used to start the system normally before the display screen needs to be replaced;
[0063] Start and load module 12, after being used for system starting successfully, start application program and load dynamic storehouse;
[0064] The opening module 13 is used for the application program to open the node interface defined in the dynamic library;
[0065] Writing module 14, is used for application layer calls described node interface and writes the display screen parameter to be replaced;
[0066] A storage module 15, configured to store the parameters of the display screen to be replaced in a storage device;
[0067] The restart module 16 is used to restart the system to realize the modification of the display screen parameters.
[0068] In Embodiment 2 of the present invention, the system may further include:
