Problems solved by technology

However, in the way of infrared touch frame, when the emitted light is blocked, the touch function will be lost, and the touch sensitivity at the edge of the screen is low
The position of the probe erected on the edge of the screen is also difficult to ignore, and the big black border on the edge of the screen cannot be avoided
[0003] Other display touch solutions, including capacitive, vector pressure sensing, surface acoustic wave, metal mesh, piezoresistive, and infrared, are generally limited by the contradiction between cost and full-scale control, and it is difficult to Full-size touchscreen control with low latency at a low cost
That is, during the implementation process, it was found that at least the following problems existed in the traditional technology: the current touch method has a problem of high delay

Abstract

The invention relates to a screen refreshing positioning method and device, display equipment and a storage medium. The screen refreshing positioning method comprises the following steps: acquiring touch position information; wherein the touch position information is acquired by a touch pen through lamp bead data displayed by the touch object based on a refreshing strategy; wherein the refreshing strategy comprises a driving instruction used for indicating that the current display content of the touch object comprises a lamp bead position; wherein the lamp bead data comprises low-gray data used for expressing lamp bead positions; and analyzing the touch position information to obtain a refreshing sequence of the low-gray data in the lamp bead data, and determining a current touch point position of the touch pen based on the refreshing sequence. The low-delay interactive touch of the screen can be realized on the premise of not influencing the display quality.

Description

technical field [0001] The present application relates to the technical field of touch interaction, in particular to a screen refresh positioning method, device, display device and storage medium. Background technique [0002] For LED (Light-Emitting Diode, light-emitting diode) display screens of hundreds of inches, the lowest-cost way to realize touch control is to use infrared touch frame. Including infrared touch frame and stylus, the method is to use a series of infrared probes placed on the edge of the screen, and the probes will shine on the tip of the stylus to generate reflection. By detecting the reflected light of different probes, the exact coordinates of the current landing point can be calculated. However, in the infrared touch frame method, when the emitted light is blocked, the touch function will be lost, and the touch sensitivity at the edge of the screen is low. The position of the probe erected on the edge of the screen is also difficult to ignore, and ...
