Electronic Device

A method, comprising:

• storing, in a first display buffer, a display signal of a first display area and a display signal of a second display area, wherein a display screen comprises the first display area and the second display area, and wherein a camera is disposed below the display screen and opposite to the second display area;
• sending the display signal of the first display area to the first display area;
• determining whether the camera is started;
• sending the display signal of the second display area to the second display area, and controlling matching between the display signal sent to the first display area and the display signal sent to the second display area when the camera is not started;
• and
• preventing the display signal of the second display area from being sent to the second display area when the camera is started.

An electronic device, comprising:

• a display screen, wherein the display screen comprises a first display area and a second display area, and wherein a material of a display screen corresponding to the second display area is a transparent material;
• a camera, wherein the camera is disposed below the display screen and opposite to the second display area;
• and
• a first display buffer;
• and
• a second display buffer,
• wherein the first display buffer is configured to:
• store a display signal of the first display area and a display signal of the second display area;
• send the display signal of the first display area to the first display area;
• determine whether the camera is started;
• send an instruction to the second display buffer that indicates whether the camera is started;
• and
• when the camera is not started, control matching between the display signal sent to the first display area and the display signal sent to the second display area;
• and
• wherein the second display buffer is configured to:
• read the display signal that is of the second display area and that is stored in the first display buffer;
• when the instruction indicates that the camera is not started, send the display signal of the second display area to the second display area;
• and
• when the instruction indicates that the camera is started, prevent the display signal of the second display area from being sent to the second display area.
