岚威防潮显像管座（Lavia moistureproof kinescope seat） Product Name: moisture proof kinescope seat Brand: Lan Wei Model: LW-8-6-4 Lan Wei (moisture) tube Origin: Guangdong, Shenzhen Lan Wei introduction 2008-8-20 22:52:58 moisture-proof socket At present... With CRT (cathode ray tube, also known as the tube) display color TV TV image itself is a very mature product, but the type of color TV in the air moist regions tend to be early (about three months inside the shortest) on blurred image, a image gradually clear fault the phenomenon, as short as a few minutes, or hours, cannot recover from serious, although the TV manufacturers have taken many measures, proved the actual effect is not obvious, so the annual TV manufacturers and users of avoidance of such maintenance of image blur spend a lot of manpower and material resources. The main reason of the failure is caused by a television tube. As shown in Figure 1 for the existing technical disclosure of traditional pipe structure, discharge cavity C technology base for traditional non closed structure, the focusing electrode leads between the end and the substrate B and D matrix A T connection buckle with the larger gap, the humidity in the discharge chamber and the surrounding environment such as the same. It is affected by the surroundings, corrosive substances in the environment surrounding the erosion of contact 1 (focus) produced by oxide and contact 1 (focus) metal ions 3 arc discharge generated the grounding needle attached to the plastic surface and the focusing cavity resulting in leakage, resulting in the focusing voltage drop, CRT focus on bad thus, the phenomenon of image blur; because the socket close to the tube heating filament ends, when the normal work by heating the filament tube tube so that the influence of high temperature, cooling after shutdown seat and ambient temperature One seat around the absorption of moisture moisture in the air to focus in the cavity, the cavity due to the focus of the next boot to
