Abstract

The invention provides a flexible screen bending degree detection method and terminal. The method comprises the following steps: when the capacitance of a capacitive touch screen changes, detecting the capacitance change value of the capacitive touch screen; obtaining the size of the changed areas subjected to the capacitance change; keeping the capacitive touch screen in contact with the flexible screen so that the capacitance of the capacitive touch screen changes according to the bending of the flexible screen; according to the capacitance change value and the size of the changed areas of the capacitive touch screen, determining the size of the areas on the flexible screen that have been deformed as well as the deformation amount; and according to the size of the areas on the flexible screen that have been deformed as well as the deformation amount of the flexible screen, determining the bending degree of the flexible screen. In the invention, such principle is used that when bending occurs in a flexible screen, the touch screen carried in a module is subjected to deformation accordingly with the result that the capacitance changes. Through the acquisition of the data concerning the capacitance change to determine the bending degree of the flexible screen, it is possible to accurately determine whether the flexible screen is subjected to bending or excessive bending without increasing the thickness of the flexible screen module, therefore, raising the user's use experience.

Description

technical field [0001] The invention relates to the field of terminal protection, in particular to a method for detecting the bending degree of a flexible screen and a terminal. Background technique [0002] With the maturity of flexible screen technology, more and more terminals such as mobile phones use flexible screens as display screens, which greatly enhances the user experience, but also introduces some problems, such as excessive bending of the flexible screen, which leads to the screen damage, etc. [0003] In the prior art, such as the Chinese patent with the application number CN201410494016.2, by adding electrodes on two flexible substrates, the two electrodes are respectively connected with different voltages, and the electrodes of the two substrates are brought into contact when the two substrates are bent. A current is generated between them, so that it is known that the flexible screen has been bent. [0004] However, the existing flexible screen bending det...
