Abstract
A microdisplay is provided in which a display area, a bonding pad connected to the display area, and a contact pad operatively connected to the bonding pad are all located on a silicon die. An electrically conductive, coated glass is located over the display area and is electrically connected to the contact pad by a flexible conductive material. Under the coated glass is a material which responds to electricity to control the transmission or emission of light.
Claims18
A display device based on an electro-optical material, comprising:
- a semiconductor substrate including an electrical display area, a first bonding pad connected to said electrical display area, a second bonding pad, and a contact pad operatively connected to said second bonding pad;
- a transparent cover having an electrically conductive coating disposed thereon;
- an electrically responsive material disposed between said semiconductor substrate and said transparent cover over said electrical display area;
- and
- a flexible conductive material disposed between said contact pad and said transparent cover in conductive contact with said electrically conductive coating.
