CRT projector

The red, green and blue portions of the incoming video signal are processed and sent to the respective CRTs whose images are focused by their lenses to achieve the overall picture on the screen.

The image in the Sinclair Microvision flat CRT is viewed from the same side of the phosphor struck by the electron beam.

The other side of the screen can be connected directly to a heat sink, allowing the projector to run at much brighter power levels than the more common CRT arrangement.

Liquid-coupled projector CRTs have a curved-inwards face with coolant and (on the side that faces the CRT's electron gun) a screen that is curved towards the inside with a dichroic coating, the coating increases light output[16] while the curvature conforms it to the curved back lens of the projector, reducing image halos.

This means that eventually the glycol can have too much water, breaking the glass of the container when it expands due to heat.
