| 摘要 |
The present invention relates to a touch sensing apparatus including a display panel including a touch screen having a plurality of touch sensors; a touch sensing circuit including at least one sensing unit for differentially receiving self-capacitance signals from first and second touch sensors adjacent to each other among the touch sensors and for detecting the capacitance variation; and a touch controller for analyzing touch raw data received from the touch sensing circuit to calculate coordinates of a touch input position. The sensing unit generates a delay for the capacitance variation between the adjacent touch sensors, counts the delay, accumulates the number of delays, and then converts the accumulated value into digital data to generate the touch raw data. |
