In the case where the red saturation is less than the minimum saturation, the red proportion is increased, thereby increasing the red saturation. The adjustment of the saturation of the blue color and the saturation of the green color is similar to the adjustment of the saturation of the red color, and will not be repeated herein.
Fig. 2 is a schematic flow chart illustrating a display screen calibration method according to another embodiment of the present invention. The display screen calibration method is applied to electronic equipment, and the electronic equipment comprises a camera and a display screen. The camera can be separated from the electronic device.

Specifically, fig. 6 shows a flowchart of a display screen calibration method according to another embodiment of the present invention. The display screen calibration method is applied to electronic equipment, and the electronic equipment comprises a camera and a display screen.

And S403, under the condition that the electronic equipment is bent, and a camera of the electronic equipment is over against the target area and is close to the display screen, acquiring saturation values of three primary colors (red, green and blue) collected by the camera aiming at the target area.
For example, when the picture shown in fig. 7 is a red picture, the electronic device is bent, and the camera 305 of the electronic device is aligned with the central circle region of the red picture, the red saturation value of the central circle region is acquired by using the camera 305. Then, the electronic device displays a green picture as shown in fig. 8, and when the electronic device is bent and the camera 305 is facing the central circle region of the green picture, the camera 305 is used to capture the green saturation value of the central circle region. Then, the electronic device displays the blue picture as shown in fig. 9, and when the electronic device is bent and the camera 305 is directly opposite to the central circle region of the blue picture, the camera 305 is used to acquire the blue saturation value of the central circle region.
