RDS – New Range of 7-inch high-brightness colour TFT display panels (GKTW70S)

Review Display Systems (RDS) has announced availability of a new range of 7-inch transmissive type, high-brightness colour active matrix TFT LCDs manufactured by SGD.

Typically, models within the GKTW70S range comprise a TFT-LCD module plus LED backlight, optional touch sensor, and an LVDS or CMOS interface option. Graphics and text are displayed on a WVGA (800 x 480 pixel) 16:9 ratio screen with 262k colours.

High-brightness is 1000cd (800cd with touch panel) while backlight life-time to half brightness is a minimum of 40k hours with backlight power consumption of only 2.6W, making the units suitable for battery-powered applications. High-end applications are for outdoor and automotive use, as well as instrumentation, medical, video players, etc.

Viewing angles with contrast ratio minimum 10 are 70/70 degrees left/right and 60/60 degrees up/down. However, outside the quoted viewing cone these panels drop quite slowly to a lower contrast, so the actual viewing angles seen by the eye are better than the spec indicates.

The operating temperature range is -20C to +70C with a storage temperature range of -30C to +80C. Overall dimensions are 166.6mm x 109.4mm x 9.65mm (11.6 mm with touch panel), says the company.
