Touch determining device and method, and display device
First Claim
1. A touch determining device for a touch panel, wherein the touch panel comprises a plurality of touch areas arranged in a matrix, and the device comprises:
- a detecting unit configured to detect whether a touch electrode has a touch area with a capacitance variation value larger than or equal to a predetermined value;
an acquiring unit configured to acquire a number of the touch areas with a capacitance variation value larger than or equal to a predetermined value, in condition that such touch areas exist;
an outputting unit configured to not output an electrical signal, in condition that the number of the touch areas is one, and output electrical signals of the multiple touch areas, in condition that the number of the touch areas is multiple; and
an analyzing unit configured to determine on the outputted electrical signals to decide whether to generate a touch signal, or not.

Abstract
A touch determining device and a touch determining method for a touch panel are provided. The touch panel includes multiple touch areas arranged in a matrix. The method includes: detecting whether a touch electrode has a touch area with a capacitance variation value larger than or equal to a predetermined value; if such touch areas exist, acquiring a number of the touch areas with a capacitance variation value larger than or equal to a predetermined value; if the number of the touch areas is one, no electrical signal of a touch area is outputted; if the number of the touch areas is multiple, outputting electrical signals of the multiple touch areas; and determining on the output electrical signals to decide whether to generate a touch signal, or not.
