US 2006/0232579 A1 · WOA panel architecture

Abstract

The present invention provides solutions to simplify and reduce the resources needed for manufacturing liquid crystal display modules. Failure of mid-process steps during mass production can result in significant costs. According to certain embodiments of the present invention, a WOA display panel architecture requires fewer LCM resources or has no PCB. Although the COG process and WOA method provide higher reliability in temporary LCD production, the costs associated with the space required for wires on the PCB or display panel for larger panel sizes remains expensive. Larger panel sizes also requires an increased number of driver ICs to construct a flat display panel. Similarly, the number of wires connecting each driver IC to a timing controller IC, gamma operational amplifier IC and DC-to-DC converter IC creates spacing problems that translate into higher production costs. These problems can be solved by certain embodiments of the present invention.
