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 ground line; a display substrate including a pixel area and a non-pixel area; an array of micro LED devices on the display substrate within the pixel area; an array of bottom contacts formed on a planarization layer and underneath the array of micro LED devices; an array of ground tie lines located below the planarization layer and running between the micro LED devices in the pixel area and electrically connected to the ground line; and one or more top electrode layers over and in electrical contact with the array of micro LED devices and the array of ground tie lines.
