34.4: A Field-Sequential Color VGA AMEL Display

摘要

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 broad band 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.
