Driving Scheme Using MIS Photosensor for Luminance Control of AMOLED Pixel

Not Accessible

Your library or personal account may give you access


This paper presents a new driving scheme utilizing an in-pixel metal-insulator-semiconductor (MIS) photosensor for luminance control of active-matrix organic light-emitting diode (AMOLED) pixel. The proposed 3-TFT circuit is controlled by an external driver performing the signal readout, processing, and programming operations according to a luminance adjusting algorithm. To maintain the fabrication simplicity, the embedded MIS photosensor shares the same layer stack with pixel TFTs. Performance characteristics of the MIS structure with a ${{nc}}{{--}}{{Si}}:{{H}}/a{{-}}{{Si}}:{{H}}$ bilayer absorber were measured and analyzed to prove the concept. The observed transient dark current is associated with charge trapping at the insulator–semiconductor interface that can be largely eliminated by adjusting the bias voltage during the refresh cycle. Other factors limiting the dynamic range and external quantum efficiency are also determined and verified using a small-signal model of the device. Experimental results demonstrate the feasibility of the MIS photosensor for the discussed driving scheme.
