1. A method for determining a touch position, wherein the method comprises:
receiving a touch input by a user;
in response to the touch input, obtaining a first data matrix of a display, the first data matrix being a matrix comprising capacitance data of the display;
in a case that the first data matrix meets a first preset condition, performing first processing on the first data matrix to obtain a second data matrix; and
determining, based on the second data matrix, coordinate information of a touch point corresponding to the touch input; wherein
the first preset condition comprises: that a trigger matrix corresponding to the first data matrix meets a second preset condition, wherein the trigger matrix is determined based on the first data matrix;
wherein the second preset condition comprises:
that the trigger matrix comprises a first number of first element groups, with each of the first number of first element groups comprising a second number of first elements, and an absolute value of each of the second number of first elements being less than a first preset threshold; wherein
the first number is greater than a second preset threshold, and the second number is greater than a third preset threshold.
