Abstract

The invention discloses a flexible screen with the bending state detectable and capable of improving working efficiency and accuracy of judgement. The flexible screen comprises a basic device and a detecting device, wherein the basic device comprises a basic layer and light emitting layer attached to the basic layer, the detecting device is arranged on the basic device or in the basic device and is used for detecting at least one parameter value when the flexible screen is bent, and specifically, the at least one parameter value is used for determining the bending state of the flexible screen. The invention further discloses a method and an electronic device for detecting the bending state of the flexible screen.

Description

technical field [0001] The invention relates to the fields of communication and electronics, in particular to a flexible screen, a method for determining the bending state of the flexible screen, and electronic equipment. Background technique [0002] The application of flexible screens will become more and more popular with people's demand for portable, easy-to-use, and multi-purpose devices. However, many current technologies related to flexible screens still have many problems. For example: when the flexible screen is folded into different shapes, the flexible screen electronic device will become an electronic device of different forms. for different applications. However, in the prior art, it is impossible to know the current state of the flexible screen automatically, and it is all judged manually, which will obviously reduce the work efficiency, and the manual judgment may not be accurate enough, and it is a waste of time. Contents of the invention [0003] Embodim...
