Abstract
An image projection system projects an image on a projection screen having phosphor particles for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The phosphor particles are bound in a binding material whose index of refraction matches the index of refraction of the phosphor particles to reduce back scattering of light.
