Active matrix display panel with ground tie lines

摘要

A display panel and a method of forming a display panel are described. The display panel may include a thin film transistor substrate including a pixel area and a non-pixel area. The pixel area includes an array of bank openings and an array of bottom electrodes within the array of bank openings. A ground line is located in the non-pixel area and an array of ground tie lines run between the bank openings in the pixel area and are electrically connected to the ground line in the non-pixel area.

主权项

1. A display panel comprising:
a display substrate including an array of ground tie lines; a bank layer including an array of bank openings, and an array of ground tie line openings exposing the array of ground tie lines underneath the bank layer; an array of bottom electrodes, each discrete bottom electrode spanning a bottom of a corresponding bank opening and over the bank layer; an array of ground tie line contacts spanning a bottom of the array of ground tie line openings and over the bank layer; and an array of vertical LED devices, each vertical LED device comprising an inorganic semiconductor-based p-n diode bonded to the bottom electrode for a corresponding bank opening.
