Abstract

The present disclosure discloses an early warning method, an early warning apparatus, and a flexible display apparatus. The early warning method includes: generating first early-warning information on a flexible display when the flexible display stored in a flexible display apparatus satisfies an extension early-warning condition; obtaining a first extended length of the flexible display; determining whether the first extended length reaches a first preset length threshold; and if yes, eliminating the first early-warning information from the flexible display.

First claim

What is claimed is:

1. An early-warning control method, comprising:
displaying a first early-warning image on a flexible display when the flexible display stored in a flexible display apparatus satisfies an extension early-warning condition;
obtaining a present extended length of the flexible display;
detecting whether the present extended length reaches a first preset length threshold; and
controlling the flexible display to exit from the first early-warning image when the present extended length reaches the first preset length threshold;
when the present extended length is the first preset length threshold, detecting whether the flexible display is extruded by an external force so as to determine whether the flexible display receives a trigger signal, wherein the trigger signal is configured to trigger the flexible display to curl up; and
displaying a second early-warning image when the flexible display receives the trigger signal.

2. The method of claim 1 , before displaying the first early-warning image on the flexible display when the flexible display stored in the flexible display apparatus satisfies the extension early-warning condition, further comprising:
obtaining an extended length during an extension of the flexible display when the flexible display stored in the flexible display apparatus begins to extend;
detecting whether the acquired extended length reaches a second preset length threshold; and
determining that the flexible display satisfies the extension early-warning condition when the acquired extended length reaches the second preset length threshold.

3. The method of claim 1 , wherein displaying the first early-warning image on the flexible display comprises:
activating a circuit signal in the flexible display;
controlling the flexible display according to the circuit signal to prestore the first early-warning image; and
displaying the first early-warning image.

4. The method of claim 1 , after controlling the flexible display to exit from the early-warning image, further comprising:
sending a message for indicating end of extension.

5. The method of claim 1 , wherein the first preset length threshold is a length of the flexible display when the flexible display is fully extended.

6. The method of claim 2 , wherein the second preset length threshold is 90% of a length of the flexible display when the flexible display is fully extended.

7. The method of claim 1 , wherein the first early-warning image is selected from a group including graphic information, information composed of graphic and text.

8. An early-warning control apparatus, comprising:
a displaying module, configured as a controller, and configured to display a first early-warning image on a flexible display when the flexible display stored in a flexible display apparatus satisfies an extension early-warning condition;
an obtaining module, configured as a sensor, and configured to obtain a present extended length of the flexible display;
a detecting module, configured as the controller, and configured to detect whether the present extended length reaches a first preset length threshold; and
a sending module, configured as the controller, and configured to control the flexible display to exit from the first early-warning image when the present extended length reaches the first preset length threshold;
wherein:
when the present extended length is the first preset length threshold, the detecting module is further configured to detect whether the flexible display is extruded by an external force so as to determine whether the flexible display receives a trigger signal, wherein the trigger signal is configured to trigger the flexible display to curl up; and
wherein the displaying module is further configured to display a second early-warning image when the flexible display receives the trigger signal.

9. The apparatus of claim 8 , further comprising a determining module,
the obtaining module is further configured to obtain an extended length during an extension of the flexible display when the flexible display stored in the flexible display apparatus begins to extend;
the detecting module is further configured to detect whether the acquired extended length reaches a second preset length threshold; and
the determining module is configured as the controller, and configured to determine that the flexible display satisfies the extension early-warning condition when the acquired extended length reaches the second preset length threshold.

10. The apparatus of claim 8 , wherein the displaying module comprises:
an activating unit, configured to activate a circuit signal in the flexible display;
an image acquiring unit, configured to control the flexible display according to the circuit signal to prestore the first early-warning image; and
an image displaying unit, configured to display the first early-warning image.

11. The apparatus of claim 8 , further comprising:
a message indicating module, configured as the controller, and configured to send a message for indicating end of extension when the first extended length reaches the first preset length threshold.

12. The apparatus of claim 8 , wherein the first preset length threshold is a length of the flexible display when the flexible display is fully extended.

13. The apparatus of claim 9 , wherein the second preset length threshold is 90% of a length of the flexible display when the flexible display is fully extended.

14. A flexible display apparatus, comprising a flexible display, and an early warning control apparatus, wherein,
a displaying module, configured as a controller, and configured to display a first early-warning image on a flexible display when the flexible display stored in a flexible display apparatus satisfies an extension early-warning condition;
an obtaining module, configured as a sensor, and configured to obtain a present extended length of the flexible display;
a detecting module, configured as the controller, and configured to detect whether the present extended length reaches a first preset length threshold; and
a sending module, configured as the controller, and configured to control the flexible display to exit from the first early-warning image when the present extended length reaches the first preset length threshold;
wherein:
when the present extended length is the first preset length threshold, the detecting module is further configured to detect whether the flexible display is extruded by an external force so as to determine whether the flexible display receives a trigger signal, wherein the trigger signal is configured to trigger the flexible display to curl up; and
the displaying module is further configured to display a second early-warning image when the flexible display receives the trigger signal.

15. The apparatus of claim 14 , wherein early warning control apparatus further comprises: a determining module,
the obtaining module is further configured to obtain an extended length during an extension of the flexible display when the flexible display stored in the flexible display apparatus begins to extend;
the detecting module is further configured to detect whether the acquired extended length reaches a second preset length threshold; and
the determining module is configured as the controller, and configured to determine that the flexible display satisfies the extension early-warning condition when the acquired extended length reaches the second preset length threshold.

16. The apparatus of claim 14 , wherein the displaying module comprises:
an activating unit, configured to activate a c
