Perfect flat CRT discussed from a standpoint of “viewing performance”

This paper describes features of the perfect flat CRT as well as major technologies used to realize it. An analysis of the relationship between viewer´s eye point and picture distortion is done, using computers to show that the perfect flat CRT is ideal as a display device because no picture distortion occurs regardless of viewer´s eye point, and an object moving on the CRT screen can be viewed with no distortion regardless of its location on the screen. Also, the developed tempered glass bulb technology is discussed as one of major innovations necessary in realizing this perfect flat CRT
