Enhanced Rugged+ TFT display delivers high-temperature performance

Latest from KOE Europe is a new enhanced 7-inch Rugged+ TFT display module, the TX18D205VM0BAA. It features the latest generation in-plane (IPS) switching technology, WVGA (800 x 480 pixels) resolution and a 15:9 wide aspect ratio, improved optical performance and an extended operating temperature range. For operation in extreme temperature environments the operating temperature range has been extended to -40C to +85C (an increase over the previously specified -30C to +80C). The storage temperature range is also increased to -40C to +90C. Optical, mechanical and environmental performance characteristics have also been improved. The TFT is designed for use in high reliability industrial, medical, marine, automotive and aerospace applications where consistent and guaranteed operation under extreme temperature, mechanical shock and vibration are a necessity. For dedicated human-machine interface applications, the latest IPS display technology delivers exceptional colour saturation and stability, high contrast and deep black levels with 170 degree wide viewing angles (vertical and horizontal). The 7-inch display features a contrast ratio of 1000:1 and a white LED backlight with a brightness of 800cd/m² and a specified 70K hour half-brightness lifetime. These features ensure that display images are exceptionally bright, colourful and concise, says the company. Mark Stephenson, technical marketing manager, KOE Europe, said: "The new 7.0-inch display employs the most recent version of IPS technology, which delivers strong optical performance with wide viewing angles and highly consistent colour reproduction. Rugged+ displays have been developed to have robust mechanical, electrical and environmental characteristics that are highly resistant to shock, vibration, electro-static discharge and temperature variation. Additionally, we are confident that the new enhanced Rugged+ displays will be commercially competitive in an aggressive marketplace." A 40-pin CMOS interface supports 6-bit RGB data which enables a colour palette of up to 262k colours. The 7.0-inch display module has mechanical outline dimensions of 167.7mm (w) x 109.45mm (h) x 9.0mm (d) and an active LCD area of 152.4mm (w) x 91.44 mm (h). Also introduced, is the 7-inch TX18D206VM0BAA display module which features the same mechanical and optical specification but implements a 20-pin LVDS interface.
