Abstract
The embodiments of the present invention provide a touch detecting method and a touch detecting apparatus. The touch detecting method may include: dividing a plurality of detecting rows in a touch screen into row groups; determining a selected detecting row in each row group; performing a primary touch detecting on pixel points in each detecting row in each row group, wherein the touch detecting on the pixel points in the same pixel column in the same row group is performed synchronously; upon there being a pixel column existing touch feedback in any row group, performing a subsidiary touch detecting on the pixel points in the selected detecting row in the pixel column, to determine the pixel point being touched. The touch detecting method and touch detecting apparatus according to the embodiments may solve problems of responding slowly, halting, or not responding caused by too many touch detecting times in the prior art.
