Abstract: A display may include a substrate, an array of thin film transistors, an array of micro-light-emitting diode elements supported by the substrate and an array of sensing elements supported by the substrate. Each sensing element may include a continuous conductive layer functioning as part of the sensing element and extending along the substrate as an electrically conductive trace connected to one of the thin film transistors.

Abstract: A micro-structure transfer system may include a printhead and a pressure control device to control a pressure of fluid coupled with the printhead. The pressure control device forms a meniscus of fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures. A printhead for transferring micro-structures includes a number of fluid chambers, a number of nozzles defined in an orifice plate through which fluid may exit the chambers, and a pressure control device to control a pressure of fluid within each of the chambers. The pressure control device forms a meniscus of the fluid at a number of nozzles defined within the printhead to pick up a number of micro-structures.
