Abstract: A CRT display is provided with a multiple-pole, double-throw switching mechanism, which in conjunction with alternate circuitry provides a means for easily reconfiguring the CRT display presentation. By operating the switches the normal left to right, the top to bottom raster scan may, for example, become a bottom to top, left to right raster scan. When applied to a multicolor CRT display, a second multiple-pole, double-throw switching mechanism serves, upon operation, to redirect beam convergence signals in compliance with the reconfigured format effected by switching the deflection signals.

Abstract: A high voltage power supply of the flyback type typically used in cathode ray tube displays or TV receivers operates in synchronism with the scan rate frequency of display and may either be self-synchronizing, externally synchronized, or externally directly driven. The power supply has a relatively high efficiency (75%), regulates three output voltages to within .+-.0.1% against source voltage variations and regulates its highest level voltage output to within .+-.0.1% against source voltage and load variations.
