Why LCD prices drop ?
If you want to know why LCD prices drop, I can tell you it is Simple. It is due to the New Technology called OLED and/or SED.
OLED:
The development of OLED technology stretches right back to the 1950s, but the first demonstration of the kind of screens we know today took place in 1996. The technique utilises organic compounds that generate light when they're fed with an electric current. Deposit tiny drops of a given compound onto a glass or plastic panel and sandwich it between a grid of positive and negative electrodes and you've got a simple, single colour OLED panel. Combine three of these into one and you have the basis for a three-colour - red, green and blue - panel capable of displaying colour pictures.
Because OLED panels generate their own light, they don't need a separate light source the way an LCD panel does. That not only helps reduce their power consumption - up to 40 per cent less than LCD, it's claimed - but leads to better colour reproduction. The trouble with a backlight is that it's always lit no matter how few pixels are showing a colour other than black. OLED pixels only consume power when they're lit.
SED:
SED works in a similar way to an old-style CRT display, but instead of a huge electron gun at the back of the set and the electro magnets used to guide the electron beam across the screen's pixels, SED sets have one tiny electron transmitter mounted behind every single pixel. This means the screens can be flat like OLED, LCD and plasma displays, and can scale from standard-definition resolutions right up to HD and beyond.
