CPC G06F 3/0418 (2013.01) [G06F 2203/04107 (2013.01)] | 13 Claims |
1. A touch panel, comprising a touch chip and a touch electrode,
wherein the touch chip is configured to generate a touch driving signal and apply the touch driving signal to the touch electrode,
the touch electrode is configured to receive the touch driving signal, and generate a touch sensing signal based on the touch driving signal, and
the touch driving signal comprises a plurality of sub-signals, the plurality of sub-signals comprise a first sub-signal and a second sub-signal, and the first sub-signal is different from the second sub-signal;
wherein each sub-signal has a plurality of characteristics,
for each sub-signal, the plurality of characteristics of the sub-signal comprise a rising edge time period of the sub-signal, a falling edge time period of the sub-signal, and a duration period of the sub-signal; and
at least one characteristic of the first sub-signal is different from at least one characteristic of the second sub-signal;
wherein the plurality of sub-signals comprise a plurality of sub-signal groups, and each sub-signal group comprises N sub-signals, wherein N is a positive integer greater than 1;
the N sub-signals comprise the first sub-signal and the second sub-signal;
wherein at least two rising edge time periods in N rising edge time periods respectively corresponding to the N sub-signals are different from each other;
at least two falling edge time periods in N falling edge time periods respectively corresponding to the N sub-signals are different from each other,
in terms of time, the N sub-signals are generated successively, the N rising edge time periods respectively corresponding to the N sub-signals increase or decrease sequentially according to a generation order of the N sub-signals, and the N falling edge time periods respectively corresponding to the N sub-signals increase or decrease sequentially according to the generation order of the N sub-signals.
