Title: Cathode-ray tube, its scanning control device and its scanning method
Inventor: SAITO SATORU
IPC: H04N5/14
Filed: 2001-05-28
Abstract: PROBLEM TO BE SOLVED: To display a good quality image by solving a problem peculiar to a scanning system in the cathode-ray tube of a dual electron gun system. SOLUTION: A frame synchronizer 70 relatively delays and outputs a video signal for either split screen to the other side.
