And 104, controlling the flexible screen to stretch out or retract according to the stretching length.
Specifically, in the process of stretching out the flexible screen, the stretching position of the flexible screen is monitored in real time, and when the stretching length of the flexible screen reaches the maximum value, the flexible screen is controlled to stop stretching out, so that the electronic equipment is prevented from being damaged due to over-stretching; in the process of recycling the flexible screen, the extending position of the flexible screen is monitored in real time, and when the extending length of the flexible screen is the minimum value, the flexible screen is controlled to stop recycling, so that the electronic equipment is prevented from being damaged due to excessive recycling; when the flexible screen is used, the optimal extending length of the flexible screen is determined according to the proportion of the display objects, and then the extending or the retracting of the flexible screen is controlled.

Example two
The following further explains the control method of the flexible screen with reference to the present embodiment.
Referring to fig. 6, the method for controlling the flexible screen according to the embodiment of the present invention includes the following steps:

Alternatively, the first color may be black, white, red, etc., preferably black or white.
In this embodiment, since an actually photographed picture may be interfered by an environment, in order to reduce the environmental interference, an RGB determination threshold of a pixel point may be set, and optionally, the RGB determination threshold of a black pixel point is set to 50, specifically, when three values of RGB of the pixel point are all less than 50, the pixel point is determined to be a black pixel point; the judgment threshold value of the RGB of the white pixel point is set to be 200, and specifically, when the three numerical values of the RGB of the pixel point are all larger than 200, the pixel point is judged to be the white pixel point.
Specifically, the number of all pixel points of the second surface of the flexible screen is counted, the proportion of the number of the pixel points of the first color in all the pixel points is calculated, and the area occupied by the first color in the image is calculated according to the proportion.

the first correspondence relationship: the area occupied by the first color is in positive linear correlation with the extending length of the flexible screen;
the second correspondence relationship: the area occupied by the first color is linearly inversely related to the extension length of the flexible screen.
The following specifically explains the control method of the flexible screen under two corresponding relations:
in a first correspondence, a schematic view of the second face of the flexible screen in the non-extended, partially extended and fully extended states is shown with reference to fig. 7. The second side of the flexible screen comprises a first area and a further area, the first area being a triangular area formed by the first side, the second side and a diagonal of the flexible screen. Wherein, the first edge is any edge of the flexible screen along the extending direction (x direction in the figure), and the side length is l; the second edge is positioned at the fixed end of the flexible screen and is perpendicular to the first edge (in the y direction in the figure), and the length of the second edge is b; the third edge is the edge of the device body opposite to the flexible screen along the x direction, and the side length is a. As shown in fig. 7, in the portion of the second surface of the flexible screen facing the body of the electronic device, the area occupied by the first color gradually changes from a triangular MNP to a trapezoidal MNPQ, and the area gradually increases.
Specifically, according to the area occupied by the first color in the image, the following formula is adopted to determine the extending length of the flexible screen:
wherein x is the extension length of the flexible screen, and S is the area occupied by the first color in the image.
In a second correspondence, a schematic view of the second face of the flexible screen in a non-extended, partially extended and fully extended state is shown with reference to fig. 8. The second side of the flexible screen comprises a first area and a further area, the first area being a triangular area formed by the first side, the second side and a diagonal of the flexible screen. Wherein, the first edge is any edge of the flexible screen along the extending direction (x direction in the figure), and the side length is l; the fourth edge is positioned at the fixed end of the flexible screen and is perpendicular to the first edge (in the y direction in the figure), and the side length is b; the third edge is the edge of the device body opposite to the flexible screen along the x direction, and the side length is a. As shown in fig. 8, in the portion of the flexible screen where the second surface of the flexible screen faces the body of the electronic device, the imaging result of the first area gradually changes from the trapezoid MNPQ to the triangle MPQ, and the occupied area gradually decreases.
Specifically, according to the area occupied by the first color, the following formula is adopted to determine the extending length of the flexible screen:
wherein x is the extension length of the flexible screen, and S is the area occupied by the first color in the image.
And step 605, controlling the flexible screen to stretch out or retract according to the stretching length.
Specifically, in the process of stretching out the flexible screen, the stretching position of the flexible screen is monitored in real time, and when the stretching length of the flexible screen reaches the maximum value, the flexible screen is controlled to stop stretching out, so that the electronic equipment is prevented from being damaged due to over-stretching; in the process of recycling the flexible screen, the extending position of the flexible screen is monitored in real time, and when the extending length of the flexible screen is the minimum value, the flexible screen is controlled to stop recycling, so that the electronic equipment is prevented from being damaged due to excessive recycling; when the flexible screen is used, the optimal extending length of the flexible screen is determined according to the proportion of the display objects, and then the extending or the retracting of the flexible screen is controlled.
