Title: Richard H Hughes: Innovator in Color Display Technology

Introduction

Richard H Hughes is a prominent inventor based in Lancaster, PA (US), known for his significant contributions to color display technology. With a total of 13 patents to his name, Hughes has made remarkable advancements in the field of imaging systems.

Latest Patents

Hughes's latest patents include innovative designs for color image display systems. One notable patent describes a compact deflection yoke in a self-converging display system that encircles adjoining segments of the neck and funnel sections of a color picture tube. This design achieves a low S-spacing dimension between converging beams in the deflection center plane. The neck diameter is sufficiently large to accommodate a main focusing lens, which has a major transverse dimension more than three and a half times the beam spacing in the electron gun. The main focusing lens is formed between final focus electrodes with recessed apertures at juxtaposed ends, featuring walls with 'racetrack'-like and 'dogbone'-like contours. Additionally, asymmetric beam-forming lenses provide each beam traversing the main focusing lens with an asymmetric cross-section that has a relatively reduced vertical dimension. Another patent focuses on a color picture tube that includes an improved inline electron gun for generating and directing three inline electron beams along separate paths toward the screen. This improved electron gun features an asymmetric beam-forming region and an asymmetric main focus lens, ensuring that all portions of each beam are focused at the screen.
