Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0009] Please combine figure 1 and figure 2 The touch screen involved in the touch recognition method of the present invention includes a space sensing layer and a signal processor electrically connected to the space sensing layer, the space sensing layer can sensitively perceive capacitance changes caused by external objects, and the The external object may be a finger or other stylus that can cause a change in the capacitance of the space sensing layer. The signal processor receives the capacitance change signal of the space sensing layer and processes the signal, and the signal processor judges the position of the finger according to the capacitance change of the space sensing layer. The change of the capacitance of the space sensing layer is related to the position of the external object, and the position where the capacitance of the space ...

Abstract

A touch recognition method, the touch screen involved in the touch recognition method includes a space sensing layer and a signal processor electrically connected to the space sensing layer, and the space sensing layer senses capacitance changes caused by external objects ; The signal processor receives the capacitance change signal of the space-separated sensing layer, and determines the position of the touch point according to the capacitance change of the space-separated sensing layer. In this way, the contact between fingers and the touch screen can be avoided, fingerprints will not be left on the touch screen, and the definition of the touch screen will be affected, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a touch recognition method of a touch screen, in particular to a touch recognition method without touching the touch screen. Background technique [0002] With the development of science and technology, touch screens have gradually replaced mechanical button panels as new operating interfaces for electronic devices such as mobile phones and notebooks. Touch screens include resistive touch screens and capacitive touch screens, which obtain coordinates in different ways. Existing resistive touch screens or capacitive touch screens need to collect touch signals through the contact of fingers with the touch screen, and then determine the touch position of the fingers. Pressing the touch screen for a long time will shorten the service life of the touch screen, and each time the touch screen is touched, the touch screen will leave fingerprints, which will affect the clarity of the touch screen. Therefore, it is necessary to provide...
