Deflection yoke - Wikipedia
网页A deflection yoke is a kind of magnetic lens, used in cathode ray tubes to scan the electron beam both vertically and horizontally over the whole screen. In a CRT television, the electron beam is moved in a raster scan on the screen.
The development of designing the deflection yoke - IEEE Xplore
网页1999年3月19日 · This paper describes the development of designing the deflection yoke (DY) of CRT from the standpoint of the historical view. It relates the introduction of field parameters, the deflection aberration theory, weight function, Trilemma, the birth of self-convergence color picture tube, multipole field correction theory, the calculation and ...
Design and optimization of magnetic lenses and deflection …
网页1975年11月1日 · Methods are described for computing the optical properties of any combination of magnetic lenses and deflection yokes, including the most general case in which the lens and deflector fields may be physically superimposed. These techniques can handle either toroidal or saddle deflection yokes, wound on either nonmangetic of ferromagnetic formers ...
A magnetic deflection up-date: field equations, CRT geometry, …
网页The evolution of the magnetic deflection yoke to wide angles and high performance, and the modification of cathode-ray-tube (CRT) structures has responded to ever-more-demanding performance in diverse applications. This article probes the past to extract those basics by which precise deflection performance of CRT systems may be calculated.
Why are the vertical deflection coils in a CRT deflection yoke so ...
网页2022年7月25日 · Looking at a typical raster CRT deflection yoke, there appear to be two very different pairs of coils. There is the pair on the inside that curves outwards, and the pair on the outside, which are wound around a ferrite core. The inside coil is the horizontal deflection coil, which seems to make sense. The coil's field lines go vertically ...
New methods and technologies for deflection yoke tuning
网页A high quality deflection yoke (DY) is one of the most important factors for a high quality monitor. The role of the deflection yoke is to deflect electron beams in horizontal and vertical directions. If the magnetic field is formed incorrectly, misconvergence of beams may occur resulting in blurred image on the screen of the monitor.
网页lead to the increase of deflection current and the rise in temperature of deflection yoke (DY). It is an efficient method to use a slot core for the increase of the deflection sensitivity. In this paper, the deflection sensitivity is defined as the proportion of the deflection angle to the coil cur rent.
