Touch identification method, touch screen and writing pen

Abstract

The invention provides a touch method, a touch screen and a writing pen. The touch method comprises the steps that the touch screen receives a position signal sent by the writing pen and converts the position signal into first coordinates, wherein the position signal is obtained in the mode that after identifying an identification label of the touch screen, the writing pen converts obtained position information; the touch screen determines second coordinates according to the signal receiving and transmitting conditions of a receiving module and a transmitting module of the touch screen; when the writing pen is switched on and used for writing, the first coordinates and the second coordinates are converted into output coordinates, and otherwise, the second coordinates are determined as output coordinates. By the adoption of the touch method, the touch screen and the writing pen, seamless switching between handwriting and pen writing can be achieved; when the writing pen is switched on and used for writing, a signal transmitted by a signal sending module and a signal transmitted by the signal transmitting module will not disturb each other due to different transmitting times; due to the scheme that the first coordinates and the second coordinates are converted into the output coordinates, an output result is more accurate; to sum up, user experience is good, and the handwriting application environment and the pen writing application environment are compatible with each other.

Description

technical field [0001] The present invention relates to the technical field of touch screens, and more specifically, to a touch recognition method, a touch screen and a writing pen. Background technique [0002] With the wide application of touch screens, there are more and more popular types of writing screens on the market, such as electromagnetic, infrared, and capacitive. Among them, infrared and electromagnetic are widely used in large-size writing screens, and they correspond to the application environments of handwriting and pen writing respectively. [0003] At present, there are two technical solutions compatible with the above two use environments, namely: increasing the density of infrared lamps, and using infrared and electromagnetic technology superposition technology. [0004] However, there are problems in the above two technical solutions: [0005] Increasing the density of the infrared lamp will cause the signal to be too small because the size of the lamp...
