Method for reducing screen input disturbance and electronic device

Abstract

The invention provides a method for reducing screen input disturbance and an electronic device. The method is applied to a screen input device at least comprising a first input screen and a second input screen. Through the obtaining of electromagnetic waves generated on the second input screen by an electromagnetic pen, first position coordinates corresponding to actual values on the second input screen by the electromagnetic pen and second position coordinates corresponding to theoretical values are calculated sequentially, differential correction is performed on the position coordinates of each point of handwriting respectively according to differential coordinates generated by the first position coordinates and the second position coordinates, and corrected position coordinates are displayed on the first input screen. The problems that during the dual screen lamination work, an electronic ink layer disturbs electromagnetic screen sensitivity and the position of handwriting displayed on the electronic ink layer is subject to deviation when characters are input into the electromagnetic screen by hand are solved.

Description

technical field [0001] The invention relates to the field of electronic technology, and more specifically, relates to a method for reducing screen input interference and electronic equipment. Background technique [0002] As a display screen specially used for reading electronic books and documents, electronic ink screen (eink) has obvious advantages such as large viewing angle reading, green environmental protection, eye protection, and ultra-low power consumption. [0003] Electromagnetic induction touch technology is an earlier technology applied to portable IT products. It mainly uses an electromagnetic pen to emit electromagnetic waves, and senses the position of the electromagnetic pen above the screen through the receiving device, and then performs positioning. Until today, the electromagnetic induction touch screen has the advantages of low cost, simple structure, good for handwriting input, and can be integrated with other touch screens, etc., so it is very popular....
