KOE Europe has added three TFT display modules featuring its UWVA (ultra-wide viewing angle) technology. The 7.0-inch TX18D45VM5BAA, 8.0-inch TX20D200VM5BAB and 10.4-inch TX26D200VM5BAA feature viewing angles of 80 degrees in all directions (up/down, left/right), and high brightness LED backlights. The 7.0-inch and 8.0-inch displays feature WVGA (800 x 480 pixels) resolution while the 10.4-inch display has SVGA (800 x 600 pixels) resolution. Suitable for many embedded, industrial, instrumentation and medical applications the 'IPS Like' TFT display modules feature COG (chip on glass) construction
KOE's UWVA displays are based on traditional TN (twisted nematic) TFT technology with design enhancements to the optical characteristics of the LCD cell which provides improved viewing angles and maintains colour stability when compared with standard TN TFT displays. As a result they offer 'IPS like' display characteristics that ensure display images are clear, and with excellent colour saturation and readability. True IPS (in-plane switching) displays provide highly consistent colour reproduction and colour saturation at all viewing angles. KOE's 'IPS like' technology enhances the optical performance of standard TN displays, creating optical characteristics similar to IPS at wide viewing angles, while offering a more cost effective display solution.
KOE Europe believes that there is a growing demand in embedded, medical and industrial markets for high quality displays that provide stable colour performance over wide viewing angles yet still offer a viable cost effective display solution. For many applications with graphical user interfaces, colour homogeneity of the display image is mandatory.
The 7.0-inch TX18D45VM5BAA display features a contrast ratio of 400:1 and a LED backlight producing a brightness of 600cd/m² with a 40 khour half-brightness lifetime. A 20-pin LVDS data interface supporting 6-bit RGB CMOS enables a colour palette of 262k colours. The module has mechanical outline dimensions of 165.0 mm (w) x 106.0 mm (h) x 8.0 mm (d) and an operating temperature range of -30°C to +80°C.
The 8.0-inch TX20D200VM5BAB features a contrast ratio of 400:1
