Abstract:
1. A positioning method for a touch display panel comprising a display panel and a touch panel, the display panel being disposed on the touch panel, wherein the touch panel has a plurality of sensing points thereon and contains a plurality of reference positions defined by a plurality of x-axes and a plurality of y-axes, the x-axes and the y-axes being alternately arranged in a matrix manner, the sensing points being distributed on the reference positions, the positioning method comprising: applying pressures with different values to each of the reference positions repeatedly, detecting a plurality of first capacitance values generated by the sensing points under the pressures with the different values, performing a calculation operation on the first capacitance values respectively corresponding to the reference positions under the same pressure value, and calculating a plurality of average capacitance values of the reference positions corresponding to the sensing points under the pressures with the different values; when an object touches the display panel, correspondingly generating a plurality of second capacitance values by the sensing points of the touch panel; comparing the second capacitance values with the average capacitance values under the pressures with the different values, and selecting the average capacitance values of the reference positions corresponding to the sensing points under a touch pressure value of the pressures with the different values; and using the second capacitance values and the average capacitance values of the reference positions corresponding to the sensing points under the touch pressure value to calculate a touch position of the object, wherein the step of comparing the second capacitance values with the average capacitance values under the pressures with the different values comprises:
