Abstract:
An ablatable laminar imaging medium useful in the manufacture of a substantially transparent electrode assembly is disclosed. The laminar imaging medium comprises a substrate, a high-index metal oxide layer, an ablatable metallic conductive layer, a high-index conductive metal oxide layer, and an ablation enhancement layer. The ablation enhancement layer has an IR-absorption greater than the IR-absorption of said high-index conductive metal oxide layer and an IR-reflectivity less than the IR-reflectivity of said high-index conductive metal oxide layer. Presence in the laminar imaging medium of the ablation enhancement layer lowers the exposure threshold of the medium and improves ablation accuracy, bothâwhen occasioned in the manufacture of LCD electrode patternsâresulting collectively and ultimately in a more reliably formed electrical architecture, less susceptible to unwanted âshortingâ.
