METHOD FOR IMPROVING TOUCH PERFORMANCE OF CAPACITIVE TOUCH SCREEN WITH NON-RECTANGULAR SHAPE
First Claim
1. A method for improving touch performance of a capacitive touch screen with a non-rectangular shape, wherein the capacitive touch screen comprises a plurality of complete cells and at least one incomplete cell for sensing, the method comprising:
- determining whether an active area of the incomplete cell is different from an active area of each of the complete cells; and
performing a mutual capacitance compensation on the incomplete cell to compensate a mutual capacitance of the incomplete cell when the active area of the incomplete cell is different from the active area of each of the complete cells;
wherein the capacitive touch screen comprises a plurality of receiver (RX) electrodes and a plurality of transmit (TX) electrodes;
wherein an intersection of one of the RX electrodes and one of the TX electrodes corresponds to one of the complete cells or the incomplete cell;
wherein performing the mutual capacitance compensation comprises;
determining whether the incomplete cell has a residual area; and
modifying a layout pattern of the incomplete cell of the capacitive touch screen to compensate the mutual capacitance of the incomplete cell when the incomplete cell has the residual area.

Abstract
A method for improving touch performance of a capacitive touch screen with a non-rectangular shape is provided. The capacitive touch screen includes plural complete cells and at least one incomplete cell for sensing. The method includes: determining whether an active area of the incomplete cell is different from an active area of each of the complete cells; and performing a mutual capacitance compensation on the incomplete cell to compensate a mutual capacitance of the incomplete cell when the active area of the incomplete cell is different from the active area of each of the complete cells.
