Data Modul – High-contrast LCD displays for automotive and industrial applications

Data Modul has announced its vertical alignment (VA) LCD technology makes it possible to realize monochrome liquid crystal display modules with high contrast ratios, with the displays background becoming a deep black colour. This deep black background can be paired with white as well as any other backlight colour, as e.g. red, green, blue, amber, etc.

Low multiplexed segment LCDs can exceed contrast levels greater than 2000:1, and even graphic versions can still achieve excellent 500:1 contrast ratio. These are significantly much better contrast ratios, compared to conventional passive LCD technology, resulting in a much higher readability.

Another key feature of VA displays are the very wide operating temperature ranges, being -40C to 85C for segment LCDs and -30C to 80C for graphic versions. The technology fully covers the high requirements of the automotive sector in relation to the operating temperature. The viewing angle of VA technology when compared to regular TN displays is much wider and can achieve up to 70 degree left / right / up / down, says the company.
