Flexible display having infrared transmitting device and infrared receiving device for recognition of folding state thereof

#The present application is the U.S. national phase entry of PCT/CN2014/092653, with an international filing date of Dec. 1, 2014, which claims the benefit of Chinese Patent Application No. 201410446925.9, filed on Sep. 3, 2014, the entire disclosures of which are incorporated herein by reference.

#The present disclosure relates to the field of flexible display interaction technologies, and particularly to a flexible display.

#The flexible display has properties such as light weight, durability and capability of being irregularly shaped etc., which allow it to be widely used in various electronic products. Having a wide prospect in application, the flexible display is yet to be improved, especially in its interactive approach.

#FIG. 1 is a structural schematic diagram of a flexible display according to an embodiment of the disclosure;

#FIG. 2 is a plan view of a flexible display of a rectangular structure according to an embodiment of the disclosure;

#FIG. 3 is an upward view of the flexible display as shown in FIG. 2;

#The technical solutions of embodiments of the disclosure will be described in clarity and entirety with reference to the accompanying drawings of embodiments of the disclosure. Obviously, the described embodiments are only illustrative, and not restrictive. All other embodiments derived by those skilled in the art without making any inventive effort, from the described embodiments of the disclosure, are within the protection scope of the disclosure.

#Referring to FIG. 1, the flexible display according to an embodiment of the disclosure may comprise a flexible display screen 1, an infrared transmitting device 3 arranged on the border of the flexible display screen 1 and comprising at least one infrared transmitting unit, an infrared receiving device 2 arranged on the border of the flexible display screen 1 and comprising at least one infrared receiving unit, and a signal processing unit 4, signally connected to each of the infrared receiving units in the infrared receiving device 2, for judging a folding state of the flexible display screen 1 based on a state of receipt of an infrared signal at each of the infrared receiving units in the infrared receiving device 2.

#In the flexible display, the infrared transmitting device 3 arranged on the flexible display screen 1 may comprise at least one infrared transmitting unit, and the infrared receiving device 2 may comprise at least one infrared receiving unit. At least a part of the infrared transmitting units of the infrared transmitting device 3 may be arranged at a first portion of the border, and at least a part of the infrared receiving units of the infrared receiving device 2 may be arranged at a second portion of the border. Optionally, the direction in which the infrared signals of the at least one infrared transmitting unit are transmitted may be perpendicular to the light emergent surface of the flexible display screen. In this way, when the flexible display screen 1 is folded in a given manner, the first portion of the border of the flexible display screen 1 will be opposite to the second portion of the border, such that the infrared receiving unit arranged at the second portion of the border is opposite to the infrared transmitting unit arranged at the first portion of the border, and thus can receive the infrared signal transmitted by the infrared transmitting unit arranged at the first portion of the border. At this point, the signal processing unit 4 may judge in which given manner the flexible display screen 1 is folded based on the state of the receipt of the infrared signals, such as whether the infrared receiving units in the infrared receiving device 2 have received the infrared signals and from which infrared transmitting unit(s) the received infrared signal(s) is/are, and in turn, judge the folding state of the flexible display screen 1. Further, the signal processing unit 4 may also control the interactive operations of the flexible display screen 1 based on the folding state of the flexible display screen 1.
