Specifically, the OSD may adjust various operation indexes of a display (display screen), including color, mode, geometric shape, and the like, so as to achieve an optimal use state.
When the electronic equipment is in the first mode, in order to improve the display effect of the display screen, the OSD does not display when the display state of the display screen does not need to be adjusted.
Therefore, when an adjustment of the display state of the display screen is required, the displayed OSD needs to be controlled to implement a subsequent adjustment based on the OSD.
Step S302: responding to the second operation to control a first area in a display screen of the electronic equipment to display OSD, wherein the touch screen and the display content in the display screen are arranged in a superposition mode;

Step S502: receiving an interrupt signal, wherein the interrupt signal is generated based on the touch screen receiving the second operation;
step S503: switching from a sleep state to an awake state based on the interrupt signal;
specifically, when the electronic device is in the first mode, the first control unit of the electronic device is in a sleep mode, and the second control unit with smaller processing capability controls the display to control the display screen to display the OSD and subsequently adjust the display state of the display screen, so that the processed data volume is larger, and the second control unit cannot undertake the processing process.
Therefore, in the application, the processing procedure for controlling the display of the OSD on the display screen and subsequently adjusting the display state of the display screen is executed by the first control unit with strong processing capability, so that the response speed of the electronic equipment is improved.
Because the OSD is not displayed in the display screen when the display state of the display screen does not need to be adjusted, the first control unit of the electronic device is in the sleep mode, and the first control unit needs to be awakened when the display state of the display screen needs to be adjusted.
Specifically, the touch screen receives the second operation to generate an interrupt signal and sends the interrupt signal to the first control unit so as to wake up the first control unit.
The first control unit of the electronic equipment is switched from a dormant state to a wakeup state based on the received interrupt signal so as to respond to the operation input by a user based on the touch screen.
