1 min read
Review Display Systems have introduced a 7inch wide format TFT Panel designed for use in high ambient light conditions. The panel also features a LVDS interface making the unit easy to drive from most single board computers. Options also include a factory fitted 4 –wire resistive touch screen.
Review Display Systems Ltd (RDS), specialist provider of optimal technical and commercial display system solutions, announces a new range of 7-inch transmissive type, high-bright colour active matrix TFT (Thin Film Transistor) LCDs from SGD – the Solomon Goldentek Display Corp.
Typically, models within the GKTW70S range, comprise a TFT-LCD module, plus LED backlight, optional touch sensor, and a 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 1000 cd (800 cd with touch panel) while backlight life-time to half brightness is a minimum of 40k hours with backlight power consumption of only 2.6 W – 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 min. 10 are 70/70° left/right and 60/60° 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 -20 to +70°C with a storage temperature range of -30 to +80°C. Overall dimensions are 166.6 x 109.4 x 9.65 mm (11.6 mm with touch panel).
