A field‐sequential color VGA AMEL display

A 0.7-inch-diagonal full-color VGA active-matrix EL display using a liquid-crystal color shutter to provide field-sequential filtering of the broadband EL emission is reported. The shutter's color-filter design improves the color gamut of AMEL displays using the SrS:Ce/ZnS:Mn EL phosphor. A digital gray-scale addressing scheme achieves 256 colors using temporal binary shading combined with error diffusion.
