COMPENSATING FOR TOUCH-SCREEN COUPLING THROUGH DISPLAY ELECTRODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240118770 titled 'COMPENSATING FOR TOUCH-SCREEN COUPLING THROUGH DISPLAY ELECTRODE
Simplified Explanation
The touch-screen display device described in the patent application includes a series of column electrodes and a series of row electrodes, with an electronic display layer arranged behind them. The row electrodes cross the column electrodes, and the impedance at each crossing is responsive to touch input proximity. A row-drive circuit applies an excitation signal to a selected row electrode and a compensation signal to other row electrodes, out of phase. A column-sense circuit senses a column signal and provides a corresponding output.
- Series of column electrodes and row electrodes
- Electronic display layer behind electrodes
- Impedance at electrode crossings responsive to touch input
- Row-drive circuit applies excitation and compensation signals

Original Abstract Submitted
a touch-screen display device comprises a series of column electrodes and a series of row electrodes, with an electronic display layer arranged behind the series of column electrodes and behind the series of row electrodes. the series of row electrodes crosses the series of column electrodes such that the electrical impedance at each crossing of a row and column electrode is responsive to the proximity of a touch input to that crossing. a row-drive circuit is configured to apply an excitation signal to a selected row electrode and to concurrently apply a compensation signal to one or more other row electrodes, the compensation signal being out of phase with respect to the excitation signal. a column-sense circuit is configured to sense a column signal from the series of column electrodes and to provide a corresponding column output.
