38.1: Effect of Black Matrix Window on CRT Luminance‐Contrast Performance

Monte Carlo simulations of light scattering in phosphor layers have been performed, showing that both luminance and reflectivity of matricized CRTs are lower than is to be expected from the matrix window transmission alone. The effect increases with increasing grain size and decreasing phosphor‐matrix overlap, and has been confirmed experimentally.
