Abstract

The present disclosure provides a method and an apparatus for controlling a flexible screen and an electronic device. The method includes: obtaining a press parameter with respect to a motor drive switch; and controlling a motor to rotate according to the press parameter, to unfold or fold the flexible screen. The flexible screen can be controlled to unfold and fold to obtain a suitable screen size.

First claim

What is claimed is:

1. A control method of an electronic device having a flexible screen, comprising:
obtaining a press parameter with respect to a motor drive switch, wherein the press parameter comprises a press duration of pressing the motor drive switch, in which the press duration is a time period corresponding to a press intensity in a range in a process from the user contacting with the motor drive switch to leaving the motor drive switch, and the press duration is obtained by obtaining an intensity change curve during a press process and counting the time period in which the press intensity is in the range according to the intensity change curve; and
controlling a motor to rotate according to a preset mapping relationship between press durations and values of rotation turns of the motor, in which one or more of the following is controlled according to the press intensity: a rotation speed and the value of rotation turns of the motor, the motor being configured to unfold or fold the flexible screen and control a speed or degree of folding or unfolding the flexible screen,
wherein the press parameter further comprises at least one of a number of presses of pressing the motor drive switch, and a press intensity of pressing the motor drive switch, and
wherein, after obtaining the press parameter with respect to the motor drive switch and before controlling the motor to rotate according to the press parameter, the method further comprises:
determining whether the press intensity is within a preset range;
determining whether the press duration is greater than a second preset threshold when determining that the press intensity is within the preset range; and performing the operation of controlling the motor to rotate according to the press parameter when determining that the press duration is greater than the second preset threshold.

2. The method according to claim 1 , wherein controlling the motor to rotate according to the press parameter comprises:
determining the value of rotation turns of the motor corresponding to the press intensity according to a preset mapping relationship between press intensities and values of rotation turns of the motor; and
controlling the motor to rotate according to the value of rotation turns.

3. The method according to claim 1 , wherein controlling the motor to rotate according to the press parameter comprises:
determining the value of rotation turns of the motor corresponding to the press duration according to a preset mapping relationship between press durations and values of rotation turns of the motor; and
controlling the motor to rotate according to the value of rotation turns.

4. The method according to claim 1 , wherein controlling the motor to rotate according to the press parameter comprises:
determining the value of rotation turns of the motor corresponding to the number of presses according to a preset mapping relationship between numbers of presses and values of rotation turns of the motor when the number of presses is less than a first preset threshold, and controlling the motor to rotate according to the value of rotation turns;
controlling the motor to rotate continuously, and controlling the motor to stop rotating till the flexible screen is fully folded or fully unfolded when the number of presses is greater than or equal to the first preset threshold.

5. An electronic device comprising:
a flexible screen, and
one or more processors,
wherein the one or more processors configured to:
obtain a press parameter with respect to a motor drive switch, wherein the press parameter comprises a press duration of pressing the motor drive switch, in which the press duration is a time period corresponding to a press intensity in a range in a process from the user contacting with the motor drive switch to leaving the motor drive switch, and the press duration is obtained by obtaining an intensity change curve during a press process and counting the time period in which the press intensity is in the range according to the intensity change curve; and
control a motor to rotate according to a preset mapping relationship between press durations and values of rotation turns of the motor, in which one or more of the following is controlled according to the press intensity: a rotation speed and the value of rotation turns of the motor, the motor being configured to unfold or fold the flexible screen and control a speed or degree of folding or unfolding the flexible screen according to the press intensity,
