Ronkonkoma, NY, May 22, 2007 – Apollo Display Technologies has developed an innovative, more efficient and more cost-effective way to make LED-backlit TFT LCDs compatible with Night Vision Imaging Systems (NVIS).
Apollo can furnish VGA and XGA resolution TFT LCDs backlit by LED rails that are addressable via the company’s standard PRISMA II industrial controller board to switch back and forth between day and night mode. Eliminated are the cumbersome and expensive filters – large glass overlays bonded to the outside of the display – that have been previously used.
These LCDs can be used in the full range of NVIS applications, including displays in military aircraft cockpits, tanks, trucks, ground mobile applications, communications equipment, electronics and a broad range of other applications.
“These are multi-tasking displays that can be used in day or night environments,” said Richard McKay, Managing Director. “This approach has never been done before. It requires no change
– more –
of the factory mechanicals, keeps part count down, and is easy and more economical to implement than existing solutions.”
A key to Apollo’s approach is its addressable LED rails. Coated CCFL lamps have been tried but, according to McKay, they negatively impact the appearance of the display in daytime mode. Apollo’s LED rails have separate day and night mode functions built into them.
“We built a unique replacement LED rail that is addressable via our standard PRISMA II industrial controller,” McKay said. “Switching back and forth between different banks of LEDs to provide a seamless transition between day and night modes is now possible. The LEDs are powered by our white LED constant current driver board.”
Two versions are available: NVIS A for upper echelon applications and NVIS B for applications with less stringent requirements. Apollo has produced an 8.4” diagonal NVIS-compatible LCD, which will be scalable up to 15” diagonal. All LCDs are fully ROHS-compliant.
