摘要： A cathode ray tube including a bulb having a screen on which a fluorescent film is formed, and a funnel portion having a neck portion on the side opposite to the screen, an electron gun mounted in the neck portion of the bulb, a deflection yoke mounted on the bulb, for deflecting an electron beam emitted from an electron gun, a velocity modulator installed around the neck portion, and an eddy current generation preventing means installed on an electrode of the electrode gun, which corresponds to the velocity modulator, for preventing generation of an eddy current by the velocity modulator. Here, the electron gun has a cathode forming a triode portion, a control electrode, a screen electrode, a plurality of focusing electrodes sequentially aligned from the screen electrode, and a final accelerating electrode which is installed adjacent to a focusing electrode the farthest away from the cathode or protects a predetermined width of the outer circumferential surface of the focusing electrode.

摘要： An electron gun for cathode ray tubes (CRTs) with a helical multi-lens electrode assembly which is formed by coupling auxiliary electrodes to both ends of a helical resistive coil. The auxiliary electrodes have claws to be embedded in bead glasses, so that the helical resistive coil is mechanically supported in the electron gun. As a voltage is applied to the helical resistive coil through the auxiliary electrodes, multiple electron lenses are created due to voltage drops in each pitch of the helical resistive coil.

摘要： In a projection CRT, an image of high brightness is displayed on a screen as an electron beam emitted from an electron gun is scanned according to an image driving signal. The image is magnified and projected through a lens unit. Here, voltage of a direct current component of the image driving signal is lower than threshold voltage of the screen for scan time and also lower than threshold voltage of the electron gun for retrace time.

摘要： A semiconductor laser CRT for driving at room temperature, whose target is pumped by an electron beam, in which a laser target is fixed to a beaker-shaped transparent glass support plate, and the glass support plate is sealed with a glass bulb using fused frit glass. Accordingly, there is no cracking of the glass bulb due to a difference in thermal expansion or destroying of a sustained airtight vacuum.
