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] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0027] It can be understood that, in the related art, when detecting the curling position of the 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 sensor, and then judged according to the strength of the field. The degree of screen curling, the accuracy of the curling position detected by this method depends on the sensitivity of the sensor, and it is not suitable for the detection of screens with excessively long cur...

Abstract

The present application proposes a flexible screen curl position detection device, method, equipment and medium, wherein the device includes: a signal generator set at one end of the flexible screen; a signal receiver set at the other end of the flexible screen; connecting the signal The metal wires of the generator and the signal receiver; the metal strips arranged at the rollable end of the flexible screen and having an angle greater than a preset angle with the metal wires; and the signal generator and the signal receiver respectively A connected processor; the processor is configured to determine the current curling position of the flexible screen according to the obtained difference between the first current signal received by the signal receiver and the second current signal emitted by the signal generator . Thus, the detection of the curling position of the flexible screen is realized, and the detection method is simple and accurate, and is suitable for detecting the curling position of any curling length, and has a wide application range.

Description

technical field [0001] The present application relates to the technical field of display screens, in particular to a flexible screen curl position detection device, method, equipment and medium. Background technique [0002] With the continuous development of display screen technology, the application of rollable flexible screens is becoming more and more extensive. In order to better control the display of the flexible screen, it is often necessary to detect the curling position of the flexible screen. [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...
