A design concept of Perfect-Flat CRT

摘要

The simulation calculated the radius of panel inner surface for the flat face CRT which makes a perfectly flat virtual screen image at each eye position. With H as screen height, display monitor CRTs used with eye positions less than 1H show that the radius of panel inner surface R=18H is the most appropriate. On the other hand, for TV CRTs with a normal eye position of 3H or greater, a radius of R=40H or more is required to obtain flat virtual image.
