Abstract
Light-absorbing particles are selectively applied to a lenticular light-transmissive screen, such as a projection television screen. The particles are selectively deposited in grooves between lenticules of the screen by filling the grooves to a predetermined depth with a slurry comprising a mixture of a volatile liquid and the light-absorbing particles. Microwave radiation is applied to the screen with the deposited particles, to effect evaporation of any unevaporated liquid and fusing of the particles to each other and to the screen.
