Touch panel, touch method thereof, and touch device

Abstract

The present invention provides a touch panel, including: a touch layer, the touch layer includes a plurality of touch areas; a pre-touch detection module, the pre-touch detection module is used for When there is a touch object within a predetermined distance range, detect the position of the touch area relative to the position of the touch object; the minimum value of the predetermined distance range is greater than zero; the pre-touch feedback module, the pre-touch feedback module It is used to generate a feedback signal according to the position of the touch area detected by the pre-touch detection module; when the positions of the touch area detected by the pre-touch detection module are different, the feedback generated by the pre-touch feedback module The signals are different. Correspondingly, the present invention also provides a touch control method using the touch panel and a display device. The present invention can prevent the occurrence of misoperation.

Description

technical field [0001] The present invention relates to the field of touch control, in particular to a touch panel, a touch control method, and a touch control device. Background technique [0002] With the rapid development of display technology, touch screens have gradually pervaded people's lives, but misoperations often occur in special-shaped touch screens and touch screens under special conditions. figure 1 It is a structural schematic diagram of the first type of touch panel in the prior art. Since the size and shape of the peripheral touch electrodes 1 are different, it is easy to cause false touch. For this reason, the prior art has designed figure 2 In the structure, the surrounding touch electrodes 1 are designed to be fan-shaped with the same size and shape. However, since the touch position is determined by the touch circuit 2 according to the position of the touch electrode 1 with the largest self-capacitance variation, adopt figure 2 In the case of the str...

figure 1 It is a structural schematic diagram of the first type of touch panel in the prior art. Since the size and shape of the peripheral touch electrodes 1 are different, it is easy to cause false touch

For this reason, the prior art has designed figure 2 In the structure, the surrounding touch electrodes 1 are designed to be fan-shaped with the same size and shape. However, since the touch position is determined by the touch circuit 2 according to the position of the touch electrode 1 with the largest self-capacitance variation, adopt figure 2 When the structure is used, when the touch position is located at the intersection of two touch electrodes 1, the changes of the two touch electrodes 1 may be equal or similar, and may also cause false touches.

In addition, when touching while driving or in some special environments such as dark and noisy, it is difficult to accurately locate the finger and the screen, and it is easy to cause some false touches
