Back to black with PMVA displays from GTK
August 14, 2013 / Press Release , Displays
The new PMVA (Passive Matrix Vertical Alignment) displays from GTK offer the look and performance of TFT displays, but with much lower costs and quicker time to market by virtue of their simpler interface and programming.
The PMVA is a custom segment and icon technology with a negative transmissive display and typically comes with a white LED backlight, with other colours available on request.
A key feature of PMVA technology is the very black contrast. Colour content can be added by silk screen printing for fixed colour content, or an LED array which offers more flexibility in terms of backlit colour combinations.
This technology offers a high contrast ratio, good all-round viewing angles, and can be operated in temperatures ranging from -10°C to +80°C. It has an operating life of 100K hours MTBF. Interface to the PCB can be achieved via flexible printed circuit or metal pins.
Clive Dickinson, Business Manager for Optoelectronics at GTK said, "PMVA technology offers customers a cost-effective way to add colour to displays where graphic content is not required. It is a high performance solution and ideal for a wide range of applications including medical electronics, industrial controls, security products and automotive electronics."
