A new series of backlight panels is available in a variety of colours and sizes, making them ideal for a wide range of applications such as LCD backlighting, large area illumination, mobile and battery operated devices, and sign, transparency and negative illumination. Until now backlighting options have been limited. Electroluminescent (EL) technology had drawbacks with limited life and the need for a voltage inverter.

Cold cathode fluorescent lamps (CCFLs) again suffered from limited life and the needed for an inverter.

Early attempts at white LED backlights relied on large multichip clusters that made them expensive and current hungry.

This new series of backlights with their combination of reflector and diffuser technologies has allowed the creation of a usable size of bright light from single panel illumination.

A wide range of sizes is available, designed to match popular LCD sizes, with four different types: surface view/array type, side view element, side view chip-on-board, and side view lamp type.

Features include: slim profile and uniform light intensity; low power consumption and long life; and low current and low voltage operation.

Single-colour devices are available in White, Blue, Green, Yellow, Amber and Red, and multicolour panels are also available on request.

Volume pricing for the Marktech backlight panels range from $0.60 to $3.00 depending on size and colour.
