ABSTRACT:
A pixel switch circuit for performing a select-and-hold function for a pixel within a reconfigurable active matrix vacuum fluorescent display is provided. The pixel switch circuit employs a driver transistor whose geometry can be tailored to optimally match the on-current for the particular phosphor of each pixel. The pixel switch circuit is particularly suitable for vacuum fluorescent displays employing different colored phosphors which have differing luminous efficiencies corresponding to the different colors.
