Problems solved by technology
[0002] The existing AP (main control chip) can support the output of two sets of MIPI signals (display signals) for display, one for the main screen and one for the secondary screen. Since each DDIC (display driver chip) requires the AP to provide a Group MIPI signal, resulting in only one DDIC can be used for the main screen and the secondary screen
[0003] IC (Integrated Circuit) has a limited number of source lines. If you use one DDIC to control the display on the main screen, and one DDIC to control the display on the secondary screen, because the size of the secondary screen is small, generally use one DDIC to control its display A better display effect can be obtained, but due to the large size of the main screen (generally 7 feet to 8 inches), if only one DDIC controller is used for display, the DDIC can support a lower resolution, which will cause the PPI of the main screen ( Pixel density) is low, the visual effect of the main screen is grainy, and the display effect is poor

The invention relates to a display data transmission system and method, electronic equipment and a storage medium. The system comprises at least two main screen display driving chips used for driving a main screen to display and an auxiliary screen display driving chip used for driving an auxiliary screen to display; a first display driving chip in the at least two main screen display driving chips is in communication connection with a main control chip of the electronic equipment through a first signal line, and the first display driving chip is further in communication connection with the auxiliary screen display driving chip. According to the system, independent display of the main screen and the auxiliary screen can be achieved without arranging a switch IC, display of the main screen can be controlled through the at least two main screen display driving chips, the resolution ratio and the pixel density of the main screen are improved, and the display effect of the main screen is better.
Description
technical field [0001] The present disclosure relates to the field of electronic equipment, and in particular to a display data transmission system and method, electronic equipment and a storage medium. Background technique [0002] The existing AP (main control chip) can support the output of two sets of MIPI signals (display signals) for display, one for the main screen and one for the secondary screen. Since each DDIC (display driver chip) requires the AP to provide a Combined with MIPI signals, only one DDIC can be used for the main screen and the secondary screen. [0003] IC (Integrated Circuit) has a limited number of source lines. If you use one DDIC to control the display on the main screen, and one DDIC to control the display on the secondary screen, because the size of the secondary screen is small, generally use one DDIC to control its display A better display effect can be obtained, but due to the large size of the main screen (generally 7 feet to 8 inches), if...
