the projection of the cam 31 is disengaged from the arc-shaped slot 20 and the bracket 1 elastically pulls at least one side of the flexible assembly back so that the flexible assembly is flattened.
Specifically, the detection unit detects the number and the watching position of the watchers and feeds back the detected first information to the processing unit; the processing unit calculates a first curvature according to the first information; the processing unit sends a first command corresponding to the first curvature to the driving mechanism; the driving mechanism controls the cam 31 to rotate by a first angle according to a first command to drive the middle protrusion of the flexible hinge 4 so that the display screen 5 is positioned at a first curvature.
The rotation angle of the cam 31 is changed according to the number of viewers and the viewing position, and thus the curvature of the flexible member can be changed.
In the watching process, the number and the watching positions of the watching personnel can be detected once every interval of set time length. Specifically, after the interval is set for a long time, the detection unit detects the number and the watching positions of the watchers again, and feeds back the detected second information to the processing unit; the processing unit calculates a second curvature according to the second information; comparing the second curvature with the first curvature, and if the second curvature is not equal to the first curvature, sending a second command corresponding to the second curvature to the driving mechanism by the processing unit; the driving mechanism controls the cam 31 to rotate by a second angle according to a second command to adjust the curvature of the display screen 5 to a second curvature.
