KOE Europe has developed  a range of Lite+ TFT LCD display modules with high brightness, long life LED backlights and high contrast ratios to provide strong optical performance.

Two new display modules are the first to introduced. The TX13D06VM2BAA is a compact, 5.0-in TFT featuring WVGA (800 x 480 pixels) resolution and a 16:9 wide aspect ratio. The 10.4-in TX26D19VM2BAA has SVGA (800 x 600 pixels) resolution and a traditional 4:3 aspect ratio. Further Lite+ TFT displays including 6.2-in, 8.0-in and 15.0-in modules are scheduled for introduction later this year.[Page Break]

The company is part of Japan Display Inc (JDI) which was formed earlier this year by the merger of the small and medium size LCD panel businesses of Hitachi, Sony and Toshiba along with the Innovation Network Corporation of Japan (INCJ). INCJ has invested $2.6 billion and is the largest shareholder in Japan Display Inc. As a result of the merger the new business is the world’s largest manufacturer of small to medium size LCD and will produce displays for mobile phones, tablet computers, automotive and medical equipment.[Page Break]

“The new range of Lite+ display panels will offer cost effective LCD modules that feature industry standard formats and interfaces but without compromising optical performance,” said Mark Stephenson, Technical Product Manager at KOE Europe. “Lite+ offers high brightness, high contrast, LED backlit displays coupled with industry standard screen sizes, resolutions and interfaces. The new 5inch TX13D06VM2BAA and 10.4inch TX26D19VM2BAA are the first Lite+ display modules to be introduced with additional displays to follow. We anticipate a high level of interest from customers who require a commercially competitive display solution but are not prepared to compromise on the quality or performance of the display image produced.”[Page Break]

The TX13D06VM2BAA features a brightness of 1000cd/m² and a 500:1 contrast ratio. The LED backlight provides a guaranteed 50K hour half brightness lifetime. The industry standard 40-pin, 6-bit RGB CMOS interface simplifies and aids system design in and supports a colour palette of up to 262k colours. The 5.0-in module has mechanical outline dimensions of 120.0mm (w) x 80.7mm (h) x 8.0mm (d) and supports an operating temperature range of -20°C to 70°C.

The 10.4” TX26D1 9VM2BAA display module has a 20-pin single channel LVDS interface that supports 8-bit RGB and enables a colour palette of up to 16.7M colours. The display has an operating temperature range of -20°C to +70°C and mechanical dimensions of 243.0mm (w) x 185.1mm (h) x 9.4mm (d). Bright, clear and concise display images are achieved with a contrast ratio of 500:1 and a white LED backlight that features a brightness of 550cd/m² and a half brightness lifetime of 50K hours. If applications demand, brightness can be increased to 800cd/m² by driving the LED backlight with an increased current of 20mA but this will impact LED lifetime.

The Lite+ TFT displays are suitable for medical, marine, process control, gaming and industrial applications. The TX13D06VM2BAA and TX26D19VM2BAA modules are available immediately through KOE Europe’s distribution partners.
