Problems solved by technology

[0002] In the mutual capacitance multi-touch system, when the user places the electronic device on an insulating object, such as placing the mobile phone on a swivel chair in the office, and the mobile phone is in a suspended state, at this time, due to the isolation of the mobile phone ground (ie GND) from the ground, At this time, the change of the user's touch is very small. If the user presses with one finger and does not move, the other finger draws a straight line parallel to the sensing channel. Phenomenon, which will affect the operating experience

Embodiment 1

[0038] refer to figure 1 , this embodiment provides a touch recognition method based on dual-channel data complement, including:

[0039] Step S101, detecting whether a single-finger press does not move, and a single-finger parallel sensing channel draws an action;

[0040]Step S102, if the single finger is pressed and does not move, and the single finger parallel sensing channel draws the line, then find the maximum value of the current touch area of ​​the single finger parallel sensing channel line point and update the single finger parallel sensing channel line point history area maximum value;

[0041] Step S103, judging whether the maximum value of the current touch area at the line point of the single-finger parallel sensing channel is at the position of the previous or next driving channel of the fixed point of single-finger pressing;

[0042] Step S104, if yes, then judge whether the single-finger parallel sensing channel dash point touch area contains two units great...

Embodiment 2

[0049] Further, step S105 is executed, and according to the judgment result of step S104, if the current touch area of ​​the single finger parallel to the sensing channel line point contains two units greater than the second touch threshold, and the single finger parallel to the sensing channel line point current touch area If the maximum value is at the position of the previous driving channel of the fixed point pressed by a single finger, the maximum value unit, the second maximum value unit, the unit in the 90° direction of the maximum value unit, and the 90° direction of the second maximum value unit Compensation is carried out for the unit, see embodiment two for details;

[0050] If the single finger is parallel to the sensing channel, the current touch area contains two units greater than the second touch threshold, and the maximum value of the current touch area of ​​the single finger parallel to the sensing channel marking point is the next driving channel of the singl...

Embodiment 3

[0067] This embodiment describes the situation that the maximum value of the current touch area at the scribing point of the single-finger parallel sensing channel is on the next driving channel of the single-finger pressing fixed point.

[0068] Firstly, according to the operation detected on the touch panel, it is determined whether the user is performing a single-finger pressing operation and a single-finger parallel sensing channel scribing operation.

[0069] If it is determined that the user is performing a one-finger press without moving and one-finger parallel sensing channel scribing operation, then collect real-time signal data, compare and calculate the real-time signal data with the pre-stored basic signal data when no touch occurs, and obtain The amount of signal change, according to the amount of signal change, the maximum value of the current touch area of ​​the single-finger parallel sensing channel scribing point is obtained;

[0070] If the maximum value of t...

Abstract

The invention provides a touch recognition method and device based on dual-channel data value compensation and a touch display device. The method comprises: detecting whether single-finger pressing immobility and single-finger parallel induction channel lineation actions occur or not; if so, detecting the maximum value of the maximum signal variation in the touch area of the scribing point of thesingle-finger parallel induction channel, and updating the maximum value of the historical area of the scribing point of the single-finger parallel induction channel; judging whether the maximum valueof the marking point touch area of the single-finger parallel induction channel reaches the position of the previous or next driving channel of the single-finger pressing fixed touch point or not; ifso, judging whether the touch area contains two units which are greater than a second touch threshold value or not; if so, performing data value supplementation on the units in the touch area; calculating a coordinate position according to the touch area after value compensation. According to the method, under the condition that a single-finger parallel induction channel scribing point is locatedbetween two induction channels, the problem of track bending caused by the fact that a single finger cannot press the other finger parallel induction channel to scribe is solved.
