Problems solved by technology

[0003] In related technologies, when detecting the curling position of a rollable flexible screen, Hall sensors are usually installed at both ends of the flexible screen to detect the strength of the field strength through the Hall sensor, and then judge the degree of curling of the screen according to the strength of the field. The accuracy of the curl position detected by this method depends on the sensitivity of the sensor, and it is not suitable for the detection of the screen with too long curl

Embodiment Construction

[0026] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the application, but should not be understood as a limitation to the application.

[0027] It is understandable that in the related art, when detecting the curling position of a rollable flexible screen, Hall sensors are usually set at both ends of the flexible screen, and the Hall sensors are used to detect the strength of the field, and then judge according to the field strength. The degree of screen curl. The accuracy of the curl position detected by this method depends on the sensitivity of the sensor, and it is not suitable for the detection of screens with too long curling edges.

Abstract

The invention provides a flexible screen curling position detection device and method, equipment and a medium, and the device comprises: a signal generator disposed at one end of a flexible screen; asignal receiver which is arranged at the other end of the flexible screen; a metal wire which is connected with the signal generator and the signal receiver; a metal strip arranged at the rollable endof the flexible screen, wherein the included angle between the metal strip and the metal wire is larger than a preset angle; and a processor connected with the signal generator and the signal receiver, wherein the processor is used for determining the current curling position of the flexible screen according to the difference between the acquired first current signal received by the signal receiver and the second current signal transmitted by the signal generator. Therefore, the detection of the curling position of the flexible screen is realized, the detection mode is simple and accurate, the method is suitable for detecting the curling position of any curling length, and the application range is wide.

Description

Technical field [0001] This application relates to the technical field of display screens, and in particular to a device, method, equipment and medium for detecting the curling position of a flexible screen. Background technique [0002] With the continuous development of display technology, the application of rollable flexible screens is becoming wider and wider. In order to better control the flexible screen for display, it is often necessary to detect the curling position of the flexible screen. [0003] In the related art, when detecting the curling position of a rollable flexible screen, Hall sensors are usually arranged at both ends of the flexible screen, and the strength of the field strength is detected by the Hall sensors, and then the degree of screen curling is judged according to the field strength. The accuracy of the curl position detected in this way depends on the sensitivity of the sensor, and is not suitable for the detection of a screen with a long curl. Summar...
