Abstract: This document describes systems and techniques directed to touch sensor integration with enlarged active area displays. In aspects, a display includes a cover layer, an array of pixels, and a plurality of transistors that control an electrical activation of one or more pixels of the array of pixels. The plurality of transistors define a smaller area than the array of pixels such that at least one pixel of the array of pixels extends beyond the area defined by the plurality of transistors and above driving circuitry (“extended emitting area”). Variable pixel and/or transistor densities can support the extended emitting area. A touch sensor is integrated between the cover layer and the array of pixels and is operatively coupled to one or more touch trace routings that are, at least partially, disposed between the cover layer and one or more pixels within the extended emitting area.

Abstract: This document describes systems and techniques directed at enlarging active areas of displays using variable pixel and/or transistor densities. In aspects, a display includes a cover layer positioned as a topmost layer and an array of pixels positioned thereunder. A plurality of transistors, positioned under the array of pixels, may control an electrical activation of one or more pixels within the array of pixels. In implementations, the plurality of transistors define a smaller area than the array of pixels such that at least one pixel of the array of pixels extends beyond the area defined by the plurality of transistors and above driving circuitry. Variable pixel and/or transistor densities can support the enlarged active area of displays and improve user experience.

Abstract: This document describes systems and techniques directed at enlarging active areas of displays in electronic devices. In aspects, a display includes a grid of transistors positioned within a display panel module to control an illumination of one or more electroluminescent layers. Routing lines extend from one or more transistors of the grid of transistors to at least one electroluminescent layer. In this way, the at least one electroluminescent layer can be positioned away from the grid of transistors and disposed above portions of display panel module driving circuitry. As a result, active areas of displays can be enlarged and information content can be maximized without a panel border area allotted to the display panel module driving circuitry surrounding transistors having to be reduced.
