Abstract
High-performance computer graphics displays for CAD utilize the Shadow-Mask CRT (SMCRT). Factors affecting colour-display quality and ergonomics include beam-to-beam convergence, beamspot profile, resolution, brightness, mask pitch, and image linearity. This paper briefly covers the results of recent experiments on eye fatique and vision. In particular, the effects of beam-to-beam misconvergence and poor spot performance in colour displays. Extensive discussion is given on beam-to-beam misconvergence: What it is, how it is corrected in different SMCRT types, and state-of-the-art techniques for controlling it. Emphasis is given to the digital-processor based convergence system employing feedback (autoconvergence). Also included are considerations given to selection of CRT types for high-performance graphics. CRTs are available with dot, slot, or line screens. There are also inline and delta configuration electron guns. Each combination of screen and gun offers tradeoffs in quality, performance, and cost.
