LCD and PLASMA

You all know LCD, liquid crystal display which is the current king of display devices. Plasma stays very near to it. LCD is cheaper and good, their black level reproductions have markedly improved, ditto their viewing angles, and their popularity makes them cheaper than Plasma. Plasmas though, are still the tech to pick if you want the absolute best visual quality.

FED – Straddling The CRT And the LCD

Field Emission Display is a self-luminescent display like CRT. Being self-lit, it offers superior brightness, contrast, viewing angle compared to an LCD. Thus FEB displays feature the picture quality of a CRT and the flat profile of an LCD or a Plasma display.

LCoS – Bringing The Chips To Play

Liquid Crystal on Silicon was a tech quickly favored and just as quickly abandoned by Intel.. It uses a silicon chip at its heart, which is why Intel was interested in the technology. Using standard chip-making processes, an LCoS embeds LCD pixel units directly on the surface of a chip. The chip itself has all the circuitry needed to operate these LCD units. The big advantage with LCoS is that the technology improves as chip fabrication improves: with a smaller chip, you can add more LCD pixels, giving better resolution.

Laser – May Be The Future King

A Laser TV will essentially replace the traditional light sources in rear – projection HD sets with Laser light. As such, it is not a new technology, but an evolution of a current standard. It could potentially improve the quality of LCD and DLP sets. Laser sets promise to be thinner, consume less power, improve refresh rates, and extend a TV’s life. They also promise to offer a wider range of colours – where the LCD reproduces about 50 per cent of the colour gamut visible to the human eye, a laser unit could go higher than 90 per cent colour gamut reproduction. This will make colours more ‘life-like’.
