GPEG and LCD display manufacturing partner Displaytech announce the introduction of their VAN LCD technology.

Vertically Aligned Neumatic liquid crystal technology dramatically improves both the contrast and transmittance of the liquid crystal display. The manufacturing process uses an inorganic alignment layer, which eliminates the aging problems associated with earlier organic alignment layers and thus ensures a very long lifetime. There is also no requirement to use a colour compensation film as the LCD has almost zero retardation at the initial alignment state.

The advantages of LCD modules produced using the VAN technology are a naturally black screen when in the off state, a high transmittance of greater than 15% which provides high brightness characters when used in negative mode and also the ability to use very low power LED backlights if this brightness is not required. The contrast ratio typically achieved is greater than 100:1 and up to 1/240 multiplexing can be utilised.

Currently this manufacturing process is available on custom designed liquid crystal modules and a range of standard displays will be launched later this year.
