Technology Development of Remote Phosphor for Avionic Cockpit Displays

Objetivo

Avionic Displays are widely used in cockpits of all fixed wing aircraft and helicopters and show a
steadily technology improvement over the years. The current avionic displays are using Liquid
Crystal Displays (LCD) with LED Backlight assemblies. The benefits for the existing LED
backlighting over previous solutions are well known: lower power consumption and more flat
display systems resulting in size and weight reduction. The quality of the cockpit display unit is
highly determined by the quality of the backlight unit.

In order to overcome the disadvantages of RGB and white LED solutions, the DERPHOSA
consortium will develop technology for an avionics displays with a new advanced backlight
concept, based on Colour Conversion by Remote Phosphor. The objective of this project is to
achieve substantial benefits on system simplicity, improving quality, reliability, power efficiency and
reduction of supplier dependence and cost for development and maintenance/operations over
lifetime.

The proposed Advanced Remote Phosphor Backlight concept is an evolution of the current LED
backlights based on RGB or white LED’s. By using a blue pump light source (LED) and a
dedicated external fluorescent phosphor layer (remote phosphor) the blue light will be converted to
a very stable customized white light. The main scientific objective of the project will be the
adaptation of the fluorescent phosphors to the wavelength of the blue pump light source, and the
tuning of the fluorescent phosphors to the colour filter of the LCD, together with the total optical
behaviour over lifetime.

The project will evaluate and realize the remote phosphor backlight concept for both direct lit and
edge lit application. To evaluate the feasibility, advantages and drawbacks of remote phosphor for
each application, two test set-ups will be realised, which will be integrated in existing Display Units
(hardware/ software).
