Abstract
A method and apparatus for avoiding pressing inaccuracies on a touch panel. The touch panel includes a panel, a control module having an analog-to-digital converter (ADC) and a delay buffer, and a processor, the delay buffer able to buffer a trigger signal for interrupting the processor. The method includes sequentially receiving a plurality of analog signals generated by the panel when the panel is touched with the control module, transforming the plurality of analog signals into a plurality of corresponding digital signals and transmitting the plurality of digital signals to the processor with the analog-to-digital converter, neglecting a first m digital signals of the plurality of digital signals, and neglecting a last n digital signals of the plurality of digital signals, where m and n are integers with values equal to or larger than 1.
