Because of the specialist nature of Meko’s business and of the roles within it, agencies often have difficulty in defining the positions and have rarely been able to find suitable candidates. For this reason, Meko does not normally approach agencies in the first instance, but advertises available jobs itself. If agencies approach us, we are … Read more
Back in March, in an editorial, I said: “Thinking about this development (OLEDs) made me wonder why Samsung would try to do something so hard. Doh! The reason for pursuing OLED is precisely because it is so hard. The Taiwanese are a long way behind on OLED, Sharp has a deep commitment to LCD as … Read more
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 inorganic light emitting materials and those using organic light emitting materials. The devices using inorganic light emitting materials are known simply … Read more
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 with varying success when other factors such as contrast, response times and power consumption are taken into account. In late 1995, … Read more
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 EL display which conform to this basic design and they fall into several groups. One group is known as “High-Field” EL … Read more
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 in projection. Like the DMD, the GLV is a digital, reflective technology in which parts of the device are physically moved … Read more
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, the FED uses a beam of electrons to excite phosphors which then emit visible light. Unlike a CRT, it uses multiple … Read more
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 and upper and lower electrodes sandwiching a material which will give off light when high frequency voltage is applied. The whole … Read more
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 the faceplate, and the amount of time the beam spends under the influence of the deflection yoke and the anode, varies. … Read more
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 . This ensures that the beam is consistently focused on a spot of the correct size on the inside of the … Read more
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 which “dangled”, or hung, from the back of a machine. These days, the term is normally applied only to devices, which … Read more
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 two methods used to do this: with an electrostatic charge and an electro-magnetic field. Electrostatic deflection uses pairs of charged plates … Read more
