Abstract

The invention provides a touch recognition method and device and a touch display device. The method comprises the following steps: acquiring signal data when touch is not generated and processing thesignal data, receiving a coordinate report command transmitted by a master controller, and acquiring real-time signal data and processing the real-time signal data according to the coordinate report command; calculating obtained signal variation data according to the processed real-time signal data and basic signal data; finding out a touch region according to the signal variation data; calculating barycentric coordinates of the touch region; analyzing current obtained barycentric coordinates and barycentric coordinates obtained in a previous time period, and determining a touch operation track; carrying out smoothing treatment on the touch operation track; detecting whether the touch operation track passes through a preset edge region or not, and if the touch operation track passes through the preset edge region, carrying out edge stretching treatment; and reporting coordinates of the touch operation track to the master controller. The recognition method is simple, a calculating flowcan be effectively saved and simplified, and the calculated amount is reduced.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch recognition method, device and touch display device.
