The setting of the first distance preset value can ensure that the sub-display area can not be generated when any two touch points exist on the main screen. If the first relative distance is greater than a first distance preset value, monitoring the sliding operation of the first touch point and the second touch point within preset time; preferably, the preset time may be two seconds, and if the first touch point and the second touch point do not perform a sliding operation within two seconds, the monitoring of the first touch point and the second touch point is stopped.

And when the first touch point and the second touch point slide along any track, acquiring a second relative distance between the first touch point and the second touch point after sliding.
Specifically, in step S3, it is determined whether a difference between the second relative distance and the first relative distance is greater than a second distance preset value. As shown in fig. 2, a first relative distance between the first touch point a and the second touch point b when the sliding operation is not performed is s1, a second relative distance after the sliding operation is performed in the direction of the arrow is s2, and when a difference between the second relative distance s2 and the first relative distance s1 is greater than a second preset distance value, the first touch point a is used as a preset position point of a first edge of the sub-display area, preferably, the preset position point may be a center point of the first edge, or may be an end point of the first edge, for example, when the first touch point a is close to an edge of the main screen, the first touch point a may be an end point of the first edge, and the preset position point may be set to ensure that the display range of the main screen is not exceeded by the sub-display area. And taking the second touch point b as one of the points of the second edge parallel to the first edge, so as to determine the relative distance between the first edge and the second edge, wherein the relative distance is the length of the third edge and the fourth edge parallel to the third edge of the sub-display area, and then obtaining the lengths of the first edge and the second edge according to the equal ratio of the sub-display area to the main screen, so as to obtain the size of the sub-display area.

Therefore, the user can acquire display content through the main screen on the one hand, and can perform touch operation in the sub-display area on the other hand, the sub-display area is small in size compared with the main screen, and the user can adjust the size of the appropriate sub-display area to realize single-hand operation in the sub-display area.

In addition, the main screen can be controlled by controlling the sub display area, and the sub display area can be enlarged, reduced and moved.
The screen control method disclosed by the embodiment of the invention solves the problem that the screen is too small due to the fact that the screen is zoomed to a certain proportion to form a control screen with a fixed proportion in the prior art, and can more flexibly generate an equal-proportion small screen in a large screen and synchronously display the small screen.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a screen control system 100 according to an embodiment of the present invention; the method comprises the following steps:

The setting of the first distance preset value can ensure that the sub-display area can not be generated when any two touch points exist on the main screen. If the first relative distance is greater than a first distance preset value, the signal processing unit 10 monitors the sliding operation of the first touch point and the second touch point within a preset time; preferably, the preset time may be two seconds, and if the first touch point and the second touch point do not perform the sliding operation within two seconds, the signal processing unit 10 stops monitoring the first touch point and the second touch point. Specifically, the user may slide only the first touch point, may slide only the second touch point, or simultaneously slide the first touch point and the second touch point. When the first touch point and the second touch point slide along any trajectory, the signal processing unit 10 obtains a second relative distance between the first touch point and the second touch point after the sliding occurs.
Specifically, the sub-display area generating unit 20 determines whether a difference between the second relative distance and the first relative distance is greater than a second distance preset value. As shown in fig. 2, a first relative distance between the first touch point a and the second touch point b when no sliding operation is performed is s1, the second relative distance after the sliding operation is performed as the arrow direction is s2, when the difference between the second relative distance s2 and the first relative distance s1 is greater than a second distance preset value, the sub-display area generating unit 20 uses the first touch point a as a preset position point of the first edge of the sub-display area, preferably, the preset location point may be a center point of the first edge, or may be an end point of the first edge, for example, when the first touch point a is close to an edge of the main screen, the first touch point a may be an end point of the first edge, the setting of the preset position point can ensure that the display range of the sub display area does not exceed that of the main screen. The sub-display area generating unit 20 uses the second touch point b as one of the points of the second edge parallel to the first edge, so as to determine a relative distance between the first edge and the second edge, where the relative distance is a length of a third edge and a fourth edge parallel to the third edge of the sub-display area, and then obtains the lengths of the first edge and the second edge according to an equal ratio between the sub-display area and the main screen, so as to obtain the size of the sub-display area.

The memory mapping unit 30 places the screen data in a memory space display memory, and the main screen display hardware displays the data of the main screen.

Specifically, the coordinate mapping unit 40 establishes a planar coordinate system with any point of the main screen as an origin, and preferably, as shown in fig. 6, the coordinate mapping unit 40 may establish a planar rectangular coordinate system with one vertex o of the main screen as an origin.
Specifically, when the sub display region acquires a sub control point g, the coordinate mapping unit 40 acquires the coordinate (x, y) of the sub control point g in response to the sub control point g located in the sub display region. The coordinate mapping unit 40 obtains a coordinate position (x ', y') of the main control point G corresponding to the sub control point G in the main screen according to the coordinate position (x, y) of the sub control point G by a coordinate mapping algorithm; preferably, when one of the vertices of the main screen is the origin o (0,0), the coordinate mapping algorithm is:
