Abstract
This disclosure provides systems, methods and apparatus for displaying images and for manufacturing display devices. Such displays can be fabricated in part by joining two substrates via a conductive seal. A substantially planar contact pad on at least one of the substrates can be exposed through a passivation layer via laser ablation, enabling the conductive seal to make contact with circuitry formed on the substrate.
Claims20
A method, comprising:
- providing a passivated display panel, including a passivation layer deposited over a plurality of display elements that are fabricated over and coupled to a control matrix formed on a first substrate;
- removing at least a portion of the passivation layer along a periphery of the display panel using laser ablation, thereby revealing a substantially planar contact pad included in the control matrix;
- and
- coupling a second substrate to the first substrate using a conductive edge seal deposited such that at least a portion of the edge seal forms an electrical connection between the contact pad and a conductive element deposited on the second substrate.
