A Reconfigurable Multimode Readout IC for Nonconductive and Capacitive Sensing With 33.9-dB SNR on 6.5-in AMOLED Panels 150 150

Abstract:

This letter presents a multimode readout IC for 6.5-in 34Tx/16Rx on-cell touch AMOLED (OCTA) panels, detecting both conductive and nonconductive objects (NCos) without panel modifications. To enable this dual detection, a reconfigurable analog front-end (AFE) is proposed, functioning as either a capacitance-to-voltage converter or a triboelectric charge sampler. In …
