Abstract A multi-colour, large-screen (2 m x 2 m, 2000 x 2000 pixels) laser-addressed liquid crystal (LC) projection display is constructed which has three LC cells corresponding to the three primary colours. Only one f-θ lens and one projection lens are used. To increase brightness, two dichroic mirrors and an off-axis projection lens are employed in the projection system.
