<p>Photoetchable glass is used to form spacer elements for large area field emission displays. Frit dots are placed onto a substrate. A sheet of photoetchable glass is exposed to UV light using a mask such that the UV light exposes the etchable areas and does not expose the areas which will form the spacers. The etchable glass is then heat treated to crystallize the UV exposed areas and to tailor the coefficient of thermal expansion. Next the glass is adhered to the frit coated substrate and the UV exposed areas etched away leaving spacers adhered to frit dots.</p> |
