TOUCH DETECTING METHOD AND FLAT DISPLAY DEVICE WITH IN-CELL TOUCH PANEL |
摘要 |
A touch detecting method comprises: enabling a sample signal in a period between driving a previous gate line and a previous two gate line before a corresponding gate line of a sense unit, and sampling a readout signal in a corresponding readout line during a sample period corresponding to the enabled sample signal by a readout unit; using the sampled readout signal during the sample period by the readout unit as a sample reference signal; enabling a sense readout signal in a period between driving the corresponding gate line of the sense unit and a next gate line, and reading out the readout signal during a sense readout period corresponding to the enabled sense readout signal; using the readout signal during the sense readout period as a sense signal; and judging whether the sense unit is touched according to the sample reference signal and the sense signal.
