In-Plane Switching (IPS)

by Dummy Admin

If LCDs are ever to replace the CRT-based display, one of the major problems to be overcome is that of narrow viewing angles. Several solutions have been developed but the different approaches have met …

High-Field Electro-Luminescents

by Dummy Admin

The basic electro-luminescent (EL) display is a sandwich consisting of an upper and a lower electrode sandwiching a material which gives off light when excited by high frequency. There are several different types of …

Grating Light Valve (GLV)

by Dummy Admin

Sony’s licensing of Silicon Light Machine’s Grating Light Valve (GLV) technology means that it may not be too long before TI’s DMD loses its place as the only Micro-Electro-Mechanical System (MEMS) to be used …

FED

by Dummy Admin

When Display Monitor began publication in 1994, one of the technologies being tipped as representing the future of flat panel displays was the FED or Field Emission Display. Similar in principle to a CRT, …

Electro-Luminescence (EL)

by Dummy Admin

Elegant in their simiplicity, electro-luminescent displays offer the thinnest profile of any colour flat panel technology. The principle of EL displays is very simple. In construction they consist of an upper and lower substrate …

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

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 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

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

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 …
