Referring to fig. 2, fig. 2 is a schematic flowchart of another electrostatic interference control method according to an embodiment of the present application, and the method is applied to the electronic device shown in fig. 1; as shown in the figure, the electrostatic interference control method includes:
s201, when the electronic equipment detects that the state of the electronic equipment meets a preset condition through the application processor, awakening the first control chip, and enabling the display screen to be in a screen-off state;
in a specific implementation, the electronic device detects, by the application processor, that a state of the electronic device satisfies a preset condition, including: the electronic equipment detects that the motion trail of the electronic equipment meets a preset motion trail through the application processor, wherein the preset motion trail is used for indicating that the electronic equipment is picked up by a user; or, detecting, by the application processor, that the electronic device is in a charging state; or, the application processor detects that the electronic device is in a preset position, where the preset position includes any one of: home and office. Therefore, the electronic equipment can predict the use requirements of the user in time aiming at different use scenes, and awaken the first control chip in advance to execute the subsequent detection process, so that the real-time performance of the electrostatic interference detection is improved.
The preset motion track can be obtained through statistical analysis according to historical operation records of the user, or pushed by a server, or actively set and input by the user, and the like, and is not limited uniquely here.
S202, the electronic equipment detects whether the display screen is subjected to electrostatic interference or not through the first control chip;
in a specific implementation, the specific implementation manner of the electronic device detecting whether the display screen is subjected to the electrostatic interference through the first control chip may be: the electronic equipment reads the state value of each register in at least one register of the display screen through the first control chip, wherein the at least one register comprises at least one of the following: a control register, a frame buffer area initial address register, a red-green-blue lookup table register and a jitter mode register; if the register with the abnormal state value exists in the at least one register, the display screen is determined to be subjected to electrostatic interference; and if the first control chip detects that the register with the abnormal state value does not exist in the at least one register, determining that the display screen is not subjected to electrostatic interference.
The electronic equipment can prestore a reference value of each register, the reference value corresponds to a value of the display screen under the condition that the display screen is not subjected to electromagnetic interference, a sample value of the display screen under the state that the display screen is subjected to electrostatic interference can be prestored, and the current state of the display screen can be determined by comparing the reference value or the sample value with the state value.
Therefore, in this example, the electronic device can accurately position the electromagnetic interference of the display screen through the register reading and comparing mechanism, and further improve the detection accuracy and stability.
S203, if yes, the electronic equipment executes a preset electrostatic interference recovery operation to eliminate the electrostatic interference;
it is understood that the implementation manner of the electronic device performing the preset electrostatic interference recovery operation to eliminate the electrostatic interference may be various, and is not limited herein.
For example, the implementation manner of the electronic device performing the preset electrostatic interference recovery operation to eliminate the electrostatic interference may be: the electronic equipment updates a register with an abnormal state value through the first control chip; updating, by the application processor, a frame of display data;
after the electronic device loads a pre-stored display initialization code through the first control chip to enable the display screen, the method further includes: and the electronic equipment displays the updated frame of display data on the display screen through the first control chip.
The display data may be image data corresponding to various interfaces such as system desktop data and application interfaces. Because the electronic equipment updates the register through the first control chip and updates the display data through the application processor, the electronic equipment can execute the two steps in parallel through the first control chip and the application processor, thereby further improving the reply speed and reducing the processing delay.

after the electronic device loads a pre-stored display initialization code through the first control chip to enable the display screen, the method further includes: and the electronic equipment displays the updated frame of display data on the display screen through the application processor.
The display data may be image data corresponding to various interfaces such as system desktop data and application interfaces. Because the register is updated by the electronic equipment through the application processor, and one frame of display data is updated by the application processor, the electronic equipment can dynamically adapt the process of updating the display data according to different use scenes based on the potential delay tolerance of a user, for example, interface data to be displayed can be pre-cached according to scenes with low delay requirements such as games, and the interface data can be directly called during updating, so that the processing real-time performance is improved. And if the electronic device only needs to display the system desktop for a scene without enabling foreground application, the display data of the system desktop can be read normally for updating. Flexibility and real-time and efficiency are improved.
Therefore, in this example, the electronic device actively updates the data to be displayed in the electrostatic interference recovery processing process, so that the problem of screen splash of the interfered original data to be displayed in the display process can be avoided, and the stability of controlling the display screen to display images by the electronic device can be improved.

after the electronic device loads a pre-stored display initialization code through the first control chip to enable the display screen, the method further includes: and the electronic equipment displays the updated frame of display data on the display screen through the first control chip.
The register is updated through the first control chip by the electronic equipment, and the frame of display data is updated through the first control chip, so that the processing pressure of the application processor can be relieved, and the resource balance utilization rate is improved.
Therefore, in this example, the electronic device actively updates the data to be displayed in the electrostatic interference recovery processing process, so that the problem of screen splash of the interfered original data to be displayed in the display process can be avoided, and the stability of controlling the display screen to display images by the electronic device can be improved.
