High brightness TFTs for outdoor use in bright ambient light
TFT LCDs can be unsuitable for use in bright or outdoor environments due to insufficient backlight brightness. KOE’s high brightness LCD display modules’ 1500cd/m² LED backlights ensure a high quality display image is maintained even under direct sunlight. The new display modules also feature an anti-glare (AG) polariser coating. The panels have a brightness rating of 1500nits which ensures that a high quality display image readability is maintained under all conditions.
The 7.0-inch and 8.0-inch displays feature WVGA (800 x 480 pixels) resolution and a wide 15:9 aspect ratio. The 10.4-inch display has SVGA (800 x 600 pixels) resolution and a 4:3 aspect ratio. The 10.4-inch TX26D200VM2BAB has a contrast ratio of 800:1 and a brightness rating of 1500cd/m². The white LED backlight has a 70k hour lifetime to half brightness. A 20-pin LVDS data interface supports 8-bit RGB.
The 7.0-inch TX20D203VM2BAA has a contrast ratio of 600:1 and a brightness rating of 1500cd/m²; its LED backlight has an estimated lifetime of 40k hours to 50% brightness. A 40-pin CMOS data interface supports 6-bit RGB. All three TFT display modules support an operating temperature range of -30°C to +80°C ensuring guaranteed operation in extreme temperature environments. Target applications include public information systems, ticketing equipment, marine navigation systems, in-vehicle interfaces, consumer information systems, point-of-sale displays and industrial instrumentation.
