Plasma, LCD, LED, OLED… con­fused yet? There was a time when all TVs shared the same tech­nol­ogy, but to­day it ap­pears that there is a new tech­nol­ogy ev­ery time you turn your set on.

Well, get ready for Quan­tum Dot! Quan­tum Dot was the talk of this year’s CES show in Las Ve­gas, and ad­mit­tedly its preva­lence took a few pun­ters by sur­prise.

But is Quan­tum Dot re­ally a break­through, or is it, as many have sug­gested, sim­ply a stop-gap un­til man­u­fac­tur­ers can get the price down, and the re­li­a­bil­ity up, of what is be­ing touted as the next big thing – OLED?

Quan­tum Dot in­volves the use of a sheet of nano-crys­tals which vary in size from 2 to 10 nanome­tres – each nano-crys­tal emits a dif­fer­ent colour de­pend­ing on its size. The sheet of these crys­tals is placed in front of the LCD back­light, with the re­sult that “colour re­pro­duc­tion rate and over­all bright­ness are sig­nif­i­cantly im­proved”.

It is way too early for us to com­ment on the ef­fec­tive­ness of this tech­nol­ogy. It is also far too early to pre­dict if it will even sur­vive (al­though LG has al­ready an­nounced a 4K screen us­ing Quan­tum Dot). What we do know, how­ever, is that this is go­ing to throw an­other twist into an al­ready con­fused mar­ket­place.
