The new Terrain Following display for the GR4 was a colour E-Scope which was the world's first application of beam-index technology. This could provide a brightness level high enough to enable easy reading of the display in direct sunlight.
A trials version of this TF display was tested on a Tornado at RAE and a development contract for terrain-following display was awarded to Ferranti.
At this time it was felt that Liquid Crystal Displays were too immature and the commercial panels were not available in the E-Scope size (the small requirement meant that the cost of a custom design was prohibitive). GEC Avionics bid a limited colour display using LCD Shutters in front of a Broad Band Phosphor CRT. This combination was not as attractive as a full colour display offered by the Beam-Index solution and the Specification was adapted to allow a small increase in the E-Scope size to accommodate the technology.
By the mid 90’s a source of LCD panels was available and the MLU displays were all replaced with this technology. This CRT is non-functional but was made by Thomson Tubes Electroniques.
