Dynamic Focus

by Dummy Admin

When looking at the operation of the deflection circuit , we see that it constantly adjusts the strength of the deflection yoke’s influence on the electron beam as the length of its path to …

Dynamic Beam Forming

by Dummy Admin

A CRTs electron beam focusing circuitry has to change the focal length of an electrostatic or electromagnetic “lens” according to where on the screen the beam is being directed, as shown in Dynamic Focus …

dongle

Dongle

by Dummy Admin

Originally, the term “dongle” was applied to any external attachment to a PC or one of its components. It seems to have originated in the UK and may have been coined to describe something …

deflection yoke

Deflection Yoke

by Dummy Admin

To make a beam of electrons do something useful, it has to be deflected from its course in some manner so as to make a trace or scan across the CRT’s faceplate. There are …

Deflection Circuit

by Dummy Admin

The deflection yoke’s electromagnets are used to alter the path of the electron beam in a CRT. The job of synchronising the influence exerted by each of the yoke’s two magnets, and so controlling …

control grid

Control Grid

by Dummy Admin

Although the Braun tube contained all the essential elements of the modern CRT, these existed in a fairly primitive form and it lacked many of the refinements which are now considered as basic components. …

braun tube

Braun Tube

by Dummy Admin

The development of the first CRT was the culmination of many years, or in this case, centuries, of research and discovery which put into place all the necessary elements. These include: the first manmade …

Bi/Tri-Linear Filtering

by Dummy Admin

A simple form of texture filtering, point sampling, could be used to scale textures prior to their being mapped onto surfaces in a 3D scene. This technique could easily introduce errors by taking a …

beam focusing

Beam-Focusing

by Dummy Admin

There are parts of the CRT that control the production, flow, acceleration and direction of the tube’s electron beam but leave its shape unaltered.  As the electrons accelerate towards the screen, they tend to …

aperture grille

Aperture Grille

by Dummy Admin

Before the three-gun, shadow mask CRT was firmly established as a standard for producing colour CRTs, several other novel systems were developed. One of these was the PDF (Post Deflection Focusing) Chromatron developed at …

antialiasing

Antialiasing

by Dummy Admin

Antialiasing, as the name suggests, is a technique used to combat an effect known as aliasing. When a line is drawn on a piece of paper, its edges appear smooth regardless of the line’s …

anode

Anode

by Dummy Admin

The control grid regulates the number of electrons which are allowed to leave the gun of a CRT by using a negative voltage to repel the electrons. Once free of the control grid’s influence, …
