In light emitting diodes (LEDs) based on inorganic light emitting materials, some of the photons released by the inorganic materials are also reabsorbed by them. In organic light emitting diodes (OLEDs), which produce light using the same electron/hole recombination method as LEDs, the frequencies of light absorbed by the light emitting materials lie mostly outside … Read more
While Hitachi was developing its In-Plane Switching (IPS) Super TFT, Fujitsu and the chemical giant Merck were taking a different approach to increasing viewing angles and, in 1996, announced the development of a new liquid crystal mode, known as Vertical Alignment (VA). In VA, as the name suggests, the molecules of liquid crystal are normally … Read more
The Foxconn story continues to reverberate. I have been collecting articles and opinions on the topic with the intention of writing a longer piece, but now seems the time to comment. This week, Foxconn said that it would move away from the ‘factory town’ concept and delegate back to government the issues of housing and … Read more
As so often in the display business, Samsung has been the topic of much discussion this week. The company is clearly being attacked in the TV market by Sony, which is looking to recover some of the market share losses that it has made in recent years. Sony, which radically restructured its European business model … Read more
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
