Abstract
A non-fade display for a CRT which includes a brightened dot, or 'bouncing ball', is described. The refreshed display makes use of relatively short persistence phosphors, together with a digital controller to momentarily stop a trace at a predetermined point corresponding to the newest data sample point, increase its intensity to form the brightened dot, follow the brightened dot with a blanked zone, and then continue with the older part of the trace.
