摘要： A display panel includes a plurality of pixels; a plurality of detection units formed in row and column directions that generate an element output signal when the display panel is touched; a detection signal processor that generates detection data based on the element output signal; and a touch determination unit that classifies the detection data in a row or column direction, that converts a row or column coordinate of a touch position or sustains a previous coordinate by comparing a reference value of each direction with the detection data, and that determines whether the touch has occurred according to the conversion number of the row or column coordinate. When the screen is continuously touched along a row or column direction, the touch or lack thereof and its position can be accurately determined by using the previous touch position information as current touch position information.

摘要： A touch position detecting method, a device using the method, and a touch screen display device having the device are disclosed. A touch sensing unit senses a touch event and outputs a sensing data. A reference update unit updates a reference data with an n-th frame sensing data provided from the touch sensing unit, based on a predetermined update signal. A position detecting unit detects the touch position by using the reference data and an (n+i)-th frame sensing data from the touch sensing unit. Therefore, the touch position is easily detected by determining a difference between the reference data and the sensing data at a certain time.
