NEC Develops Inexpensive System-ON-GLASS LCD Driver
NEC Corp. has developed an inexpensive way to make system-on-glass components to drive LCDs.
The LCD driver system is typically built from a number of chips mounted on a board and attached to the LCD panel by a ribbon cable. Over a dozen parts are used and the overall system takes up considerable room.
NEC's system-on-glass solution integrates the chips on a glass substrate that is mounted to the LCD glass substrate, eliminating the need for the board and wiring. The entire LCD driver is made from just three parts and takes the shape of a component approximately 189mm long and just 1.4mm wide.
The small size gives designers the freedom to build thinner displays with smaller frames.
Whereas system-on-glass solutions are normally more expensive than standard LCD driver systems, NEC's product is actually around two-thirds less expensive to make.
The company plans to have commercial products ready in 2006 for notebook computers, PDAs and a range of other electronic devices that have LCD screens in sizes of 3-20 inches. more...
