Abstract:
A device and method for generation of a dynamic focus correction signal for use with a CRT that includes an analog scanning processor for generating a dynamic focus correction signal that is proportional to Kx2+(1−K)x4, where x is the distance from a mid point of a viewing surface of the CRT, and K is a real number in the range 0.00 to 1.00. Embodiments of the invention find particular use in CRTs having generally flatter, squarer configurations.
