Abstract

The invention discloses a multi-scan line colorful CRT kinescope, which is characterized by the following: loading multi-group electronic beam ray launching device in the kinescope; disappearing multi-bar colorful scanning bright ray on the fluorescent screen acted by deflected magnetic field; proceeding image display through multi-scan line colorful CRT kinescope; dividing the structure of CRT kinescope into combination-typed multi-scan line colorful CRT kinescope and allocation-typed multi-scan line colorful CRT kinescope; dividing the appliance of CRT kinescope into multi-line scan, line-by-line scan, low-line frequent scan, allocation scan. The electron gun in the CRT kinescope possesses over three cathodes with each scan line corresponding to three cathodes, which launches red, green, blue electronic beam separately.

Description

【Technical field】

[0001] The present invention relates to the structure and application technology of a multi-scanning line color CRT (Cathode Ray Tube) cathode ray picture tube, especially an application technology of a device for realizing high-definition image display by using a multi-scanning line color CRT picture tube, and a An adjustment method for multi-scanning line color CRT picture tube multi-group electron beam scanning correction. Through the digital technology processing of image signals and the adoption of multi-scan line color CRT picture tubes, CRT picture tubes can achieve large screen, high brightness, high contrast, high definition, and ultra-thin performance to adapt to HDTV high-definition digital Technical requirements for televisions and high-definition image displays. 【Background technique】

[0002] General CRT monitors, such as: CRT TV sets and CRT computer monitors, the CRT picture tubes currently used are all single-scanning line CRT picture tube...
