The word “moiré” comes from the French word for mohair and is defined as “having a watered or wavelike pattern” (Collins English Dictionary). Moiré patterns can occur whenever similar, regular patterns are superimposed on each other and are offset or angled with respect to one another. They are commonly seen amongst the folds of net … Read more
“MIP map” is the name given to a collection of images to be used as surface textures when building, or rendering, a 2D representation of a 3D scene. The acronym “MIP” comes from the Latin phrase: multum in parvo which is translated as “many things in a small place”. Each of the many images stored … Read more
Liquid crystal displays (LCDs) are now so common that we take it for granted that people know what we are talking about when we use the phrase. But how many of us know what liquid crystals are? The term itself seems to be a contradiction. Crystals, such as quartz, are formed when molecules form a … Read more
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 a small LCD to address a large area LC light valve that can modulate a large light source. The light from … Read more
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 towards the target (a reflective LV) or by blocking the light-path (a transmissive LV). They were first used in projection TVs … Read more
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 emitting materials. The company’s light-emitting polymer (LEP) technology was born in Cambridge University’s Cavendish Laboratory in 1989, where three researchers (Bradley, … Read more
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
