Light Valve Amplifier/ILA

by Dummy Admin

Light Valve Amplifier (LVA) is a term used to describe a specific type of light valve developed by Hughes-JVC (Image Light Amplifier (ILA)). An LVA is a device which uses the limited brightness of …

Light Valve

by Dummy Admin

A light valve (LV) is a form of optical switch which can be used to vary the amount of light which reaches a target (e.g. a screen) by deflecting the light from its path …

The Universal Display Corporation’s TOLED is based on small-molecule organic light emitting materials. Another of the high-profile OLED development companies, Cambridge Display Technology (CDT), is putting its faith in large-molecule, or polymer, organic light …

LED

by Dummy Admin

One group of electro-luminescent (EL) devices is known as high-field ELs. The other main group is known as the Light Emitting Diodes, which is itself split into two groups consisting of those devices using …

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 …
