LANDING CONDITION MEASURING METHOD, LANDING CONTROL METHOD AND LANDING CONDITION MEASURING DEVICE OF CATHODE-RAY TUBE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a landing measuring method, a landing control method and a landing condition measuring device of a cathode-ray tube device which can measure the landing condition without the need for considering the influence of a local doming.;SOLUTION: At each measuring point 101-109 on a display screen 9 of the cathode-ray tube device 7, measurement patterns displayed in measuring regions 201a-201d are sequentially switched over at prescribed intervals and are displayed to measure mislanding quantities. Thus, since partial light emission over a long time is eliminated due to mislandigns can be controlled without the need for considering the influence of local doming.;COPYRIGHT: (C)2003,JPO
