CPC H04M 1/0266 (2013.01) [H05K 5/0017 (2013.01)] | 8 Claims |
1. An electronic device, comprising:
a body;
a display screen, located on a surface of the body, wherein the display screen comprises a plurality of sub-screens;
an actuating structure, connected with the display screen and configured to deform at different temperatures to change an included angle between at least two adjacent sub-screens; and
at least one current drive structure, electrically connected with the actuating structure and configured to input current to the actuating structure to deform the actuating structure;
wherein, the electronic device further comprises:
at least one angle sensor, located at an interior or on a surface of the display screen and configured to sense the included angle between any two adjacent sub-screens of the display screen;
wherein any two adjacent sub-screens are a first sub-screen and a second sub-screen, and the angle sensor comprises a magnet part and an induction part, the magnet part is located at an interior or on a surface of the first sub-screen, and the induction part is located at an interior or on a surface of the second sub-screen;
wherein the display screen further comprises a rotary shaft connected between at least two adjacent sub-screens, wherein the rotary shaft is connected with the actuating structure, and the actuating structure is configured to deform to drive the rotary shaft to rotate, so as to make the included angle between at least two adjacent sub-screens change;
wherein use the following steps to control the electronic device:
determining a predetermined drive current for driving the actuating structure to deform according to a predetermined included angle in a control command, and controlling at least one current drive structure to input the predetermined drive current to the actuating structure, so as to enable the included angle between the two sub-screens to reach the predetermined included angle;
determining a predetermined drive current for driving the actuating structure to deform according to the predetermined included angle in the control command, comprises:
determining predetermined deformation quantity of the actuating structure according to the predetermined included angle; and
determining the predetermined drive current corresponding to the predetermined deformation quantity, according to a relation between a deformation quantity of the actuating structure and a drive current;
determining predetermined deformation quantity of the actuating structure, according to the predetermined included angle, comprises:
acquiring a current included angle, which is predetermined and controlled, between the two adjacent sub-screens;
determining a difference of included angle between the two sub-screens according to the predetermined included angle in the control command and the current included angle; and
determining the predetermined deformation quantity, according to the difference.
