High-resolution, rugged, flat-panel LCD displays

6 April 2005 Opto-Electronics

A new range of rugged flat panel LCD displays are now available in South Africa from designer and manufacturer R&D Design Services.

Display sizes currently available range from 6-15" (15,24-38,1 cm) and the products are designed for use in fixed-wing and rotary aircraft, patrol vessels, military vehicles and even submarines.

The 15" display (LCD1502), as an example, uses a high resolution TFT display. The video input options include NTSC/PAL and RGB (VGA-XGA) with night vision goggle compatibility being an optional extra. The daylight readable (400 cd/m²) display has 1024 x 768 pixels and can provide full colour and monochrome imagery. The display can be used with either CCD or infrared sensors and possesses a picture in picture functionality with instant switching between the two. A digital freeze frame function is available as standard. Dissimilar inputs such as video and graphics can also be displayed simultaneously. RDDS proprietary video enhancement technology provides dramatic improvement of low contrast or poor quality video imagery. This enhancement allows better imagery to be obtained in poor conditions and overcomes the major effects of smoke.

The system is also compatible with moving map display systems. The front panel features large illuminated membrane controls for adjustment of brightness, contrast and colour, along with mode select controls for video input switching and enhancement functions.

RDDS flat panel displays are widely used on UK and European police helicopters and by the RAF in the Nimrod and other reconnaissance aircraft. In the case of the UK the helicopters use the FLIR Systems LEO-II electro-optical turret as designed and manufactured locally by Denel.

The 15" display weighs 6 kg, is powered from 28 V d.c., and dissipates 48 W in power.
