Abstract
An improvement for inhibiting arcing within a cathode ray tube comprises a combination including a low resistive electrical coating disposed interiorly on the forward portion of the funnel, joined with a high resistive coating disposed interiorly on the rearward portion thereof. Associated therewith are getter means having discretely shaped diffusion direction means to prevent the formation of a conductive path across the high resistive coating. The improved arc suppression combination beneficially improves the dielectric breakdown protection for both the tube and the associated circuitry.
