33-4: COA Technology Applied in ADS Mode LCDs

Abstract

COA technology used in ADS mode LCDs is analyzed through theoretical method and basic experimental verification. Compared to IPS and VA mode LCDs, more films on R/G/B will cause the special process manufacturing issues for ADS mode LCDs. It mainly presents in three problems, which are process compatibility, flatness and deep-hole process. In this paper, the risk points of COA technology are put forward, and the possible solution is also analyzed.

P‐59: Analysis of Ink‐Jet‐Printing Mura in the PI Film on TFT‐LCDs

“…As ADS mode display products, PVX and Vcom ITO layers of ADS mode need the hole process. The hole usually overlaps with BM in order to increase the aperture ratio, but it also means a deep-hole is easy to cause PI printed mura [2].…”
