Abstract:

This article presents a 10-bit source-driver (SD) IC for high-resolution OLED-on-silicon (OLEDoS) microdisplays in augmented reality (AR)/virtual reality (VR) applications. To address the stringent constraints of aggressive area scaling, sub-microsecond settling time, and high output uniformity, three key techniques are proposed. First, a demultiplexer (DEMUX)-based channel width expansion …

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

A Reconfigurable Multimode Readout IC for Nonconductive and Capacitive Sensing With 33.9-dB SNR on 6.5-in AMOLED Panels 150 150
Author(s): Sang Weun Kim, Jun Seong Kim, Dabin Yun, Seunghoon Ko

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 …

A Hybrid Touch Sensing AFE With Common-CVQ (Currents, Voltages, and Charges) Subtraction to Improve Display Noise Immunity for Large Sensing Load

A Hybrid Touch Sensing AFE With Common-CVQ (Currents, Voltages, and Charges) Subtraction to Improve Display Noise Immunity for Large Sensing Load 150 150
Author(s): Seung Hun Choi, Jun Yeol An, Jaewoong Ahn, Si-Woo Kim, Jae-Youl Lee, Yoon-Kyung Choi, Hyung-Min Lee

Abstract:

On-cell touch flexible organic light-emitting diode (OLED) displays face significant display noise (D-noise) challenges due to large parasitic capacitance ( $C_{P}$ ). To address the limitations of conventional methods, this article proposes improved common-current subtraction (CCS), incorporating common-voltage subtraction (CVS) and common-charge subtraction (CQS) techniques. CVS enhances signal-to-noise ratio (SNR) by …
