Organic light-emitting diode display with active leakage-reducing structures

A display comprising:

• a substrate;
• an array of pixels that includes first and second organic light-emitting diode pixels, wherein the first organic light-emitting diode pixel includes a first patterned electrode on the substrate and wherein the second organic light-emitting diode pixel includes a second patterned electrode on the substrate;
• a pixel definition layer on the substrate that is interposed between the first and second patterned electrodes;
• a conductive layer formed over the substrate that has a first portion that forms part of the first organic light-emitting diode pixel and a second portion that forms part of the second organic light-emitting diode pixel;
• and
• a conductive gate that is formed between the first and second patterned electrodes, wherein the conductive gate is coupled to a variable gate voltage and is configured to generate a current that mitigates leakage current through the conductive layer, wherein the first patterned electrode has an extension that is electrically connected to a contact and wherein the conductive gate is routed over the extension without overlapping the contact.
