Horizontal deflection coil for deflection yoke

Abstract

Disclosed herein is a horizontal deflection coil for a deflection yoke. The horizontal deflection coil includes an inner pincushion improving section connected to a screen bent, and sub-sections connected to the inner pincushion improving section. The inner pincushion improving section is disposed in an angular range of 45 to 60 degrees. The sub-sections include a horizontal color registration improving section for preventing a horizontal component of a green color from being widened, and a vertical color registration improving section for preventing a vertical component of the green color from being widened.

Description

technical field [0001] The present invention relates generally to horizontal deflection coils for deflection yokes used in cathode ray tubes, and more particularly to such horizontal deflection coils in which there is a section for correcting pincushion distortion, thereby eliminating additional A circuit with inner pincushion distortion. Background technique [0002] Recently, the market of display devices tends to be planarized, large-sized, high-resolution, low-power consumption, and slim, so that installation space can be reduced and space usage efficiency can be increased. [0003] In pursuit of planarization, large size, high resolution, low power consumption, and slimming, a computer monitor among such display devices has been developed. In particular, in order to meet strict environmental standards, high-quality display devices with large-sized effective screens that reduce power consumption are required. [0004] The monitor market is growing at a rate of 10% per ...

AI Technical Summary

Problems solved by technology

[0030] However, a disadvantage of conventional flat screen CRTs is that a separate pincushion correction module is required to correct pincushion distortion

[0031] For this reason, the manufacturing cost of flat screen CRTs has increased due to the increased number of assembly steps required to attach the inner pincushion correction modules to the deflector, and the increased number of parts required to manufacture the inner pincushion correction modules.
