P‐73: Innovative Controller for Touch‐Sensor Panel in Heavy‐Load Parasitic Capacitance.

The innovative design of fully differential analog front end is swhich is the parasitic capacitance of a touch sensor is approximately 60% higher than a conventional smartphone. The newly developed touch sensor controller shows approximately 40 % higher SNR than a commercialized flagship smartphone, which is defined with the noise of peak to peak value in the touch signal on the zebra pattern display.
