CATHODE RAY TUBE

摘要

PURPOSE: A cathode ray tube intensifies the intensity of the inner pressure and increases the brightness of the cathode ray tube and reduces the consumption power by shaping the inside of a funnel of the cathode ray tube as similar as possible to the locus of an electron beam. CONSTITUTION: A cathode ray tube includes: a panel(1) where a screen is formed inside; a funnel(5) having a cone part(3) where a deflection yoke is installed on its circumference, being connected to the panel; and a neck part(7) which is connected to the funnel and an electron gun is installed inside. The inner form of the cone part is formed to be a non-circle form as proceeding toward the panel part from the neck part which has a maximum diameter along a direction except a first and a second axis.
