In-cell touch panel sensing system and sensing method for the in-cell touch panel sensing system

摘要

The present invention provides an in-cell touch panel sensing system and a sensing method. The in-cell touch panel sensing system comprises sensing arrays. Each sensing array comprises: sensor plates; a first multiplexer (MUX), a first analog-to-digital converter (ADC), a second MUX, a second ADC, a third MUX, a third ADC, a fourth MUX, and a fourth ADC. The first MUX is coupled to a first row of the sensor plates and a first column of the sensor plates. The first ADC is coupled to the first MUX. The second MUX is coupled to a second row of the sensor plates and a second column of the sensor plates. The third MUX is coupled to a third row of the sensor plates and a third column of the sensor plates. The fourth MUX is coupled to a fourth row of the sensor plates and a fourth column of the sensor plates.
