Hitachi continue to enhance and develop 5.7” ¼ VGA TFT

‘A complete product redesign has enabled our design engineers to significantly impact product cost, enhance optical performance and reduce power consumption, while ensuring the new module provides a highly cost effective solution for new or existing equipment designs,” comments Mark Stephenson Product Marketing Manager, ‘The resulting enhancements ensure that Hitachi maintains its ability to provide customers with the product they need when seeking a high quality, cost effective 5.7” ¼ VGA display solution.’

The new module design implements a 2 driver Chip on Glass (COG) construction which aids ease of manufacture and provides increased display robustness and enhanced reliability. The new TX14D22VM1BAA has compact mechanical dimensions of 131.0mm (w) x 102.2mm (h) x 7.1mm (d). Hitachi’s existing 5.7” ¼ VGA modules have a thickness of 10.9mm while the new design of TX14D22VM1BAA features a 35% reduction (in thickness) and a subsequent weight reduction with the module weighing only 150g.

Exceptional optical performance, a traditional Hitachi strength, is maintained with an impressive 350:1 contrast ratio and a robust high brightness LED backlight that ensures excellent image uniformity whilst delivering a brightness of 400cd/m² and a typical lifetime of 40K hours. The TX14D22VM1BAA implements an industry standard 6-bit RGB CMOS data interface which enables an extensive colour palette of up to 262K colours to be displayed.

The new lightweight and compact TX14D22VM1BAA is partnered with a touch panel version of the display the TX14D22VM1BPA. Both display modules are mechanically compatible in all respects, other than the thickness of the module, with existing Hitachi 5.7” ¼ VGA display modules allowing existing users to easily migrate to the new displays. Both modules are ideally suitable for industrial and consumer hand held and battery powered devices and applications.
