Abstract
A pressure detection method for an in-cell touch display and a mobile device using the same are provided. The pressure detection method comprises the steps of: providing a common voltage plane corresponding to touch sensing electrodes in the in-cell touch display; detecting capacitance values of the touch sensing electrodes; setting a first area and a second area according to a center of a touched portion when the in-cell touch display is determined as being touched, wherein the second area includes the first area; and excluding the capacitance values of the touch sensing electrodes in the first area, and using the capacitance values of the touch sensing electrodes in the second area to serve as a pressure detection value to determine a pressure exerted on the in-cell touch display.
