LCD is a display system that uses Liquid crystal liquid to create polarised dots on a sheet of glass in front of a polarised sheet. When a current is passed through the LCD its molecules line up and become polarised. When this is at 90 degrees to the polarise sheet it blocks light. A Fluorescent tube behind the sheet produces light which is blocked by the LCD when polarised.
This technology uses lots of glass and is definitely NOTsuitable for a flexible display. It also uses a high current and
Organic Light emitting diodes were invented when a Japanese scientist was trying to create a super light solar cell. One night he made a mistake and wired the panel up and put voltage through the organic compound he was testing. To his surprise it lit up. OLED displays use this active light generating technology. It has the advantage of being low current and high brightness. It can also be painted onto flexible surfaces to make ultra light weight flexible displays.
Take a look at the video to see this remarkable technology:
LCD displays do not emit light on their own. For that they need a backlight, which both raises power consumption and reduces the contrast ratio. Since there is always a backlight behind the set, pure, dark blacks are nearly impossible on an LCD display. OLED displays emit their own light without the need of a backlight, giving them a darker display with a greater contrast ratio. Another difference can be the price. OLED HDTV sets also cost more than their LCD counterparts. A 32-inch OLED set at Amazon has a retail price of $1,131 as of 2010. An LCD set that is the same size can range from $500 to $700. But in Long-term predictions, the price of OLED sets will decrease rapidly as they become more economical to produce.

What is the difference between OLED LCD and Plasma panels particularly with energy efficiency and the constructional complexity?
This is the link where u can get better idea about LCD and OLED I found thhis will be very help full to this tpoic http://www.oledtvzone.com/guides/oled-vs-lcd-tv
Are LCD hdtvs as reliable as oled hdtvs?
OLED TVs have a much shorter lifespan than LCD TVs and may have burn in issues. LCD TVs are a proven technology and are much more reliable at this point.
What is the difference between LCD and EVF?
LCD = Liquid Crystal Display: this is a name for several technologies for creating an image on a flat screen.EVF = Electronic View Finder: this is the name for a part of a camera at which you look that displays the image that will be taken (or is being recorded). The EVF makes no claims about HOWthe image is formed LCD, TFT, OLED or whatever.
I've heard of plasma and LCD televisions but I'm not familiar with oled tvs. What's the diffence in a oled tv?
OLED's are brighter than LEDs, OLED's do not require Backlighting. They are easier to produce and can be made to larger sizes. They are expensive, water easily damages them.
What are the types of touchscreen which we use in mobiles and smartphones?
Types of touchscreen that are used in mobile and smartphones include TFT LCD, IPS-LCD, Resistive Touchscreen LCD, Capacitive Touchscreen LCD, and OLED.
How much of energy can be saved by watching oled tv instead of watching led-lcd tv?
OLED TV actually consumes much less power comparing to any other LCD or LED TVs. It's like OLED consumes almost 70% less power than LCD TV, but there are already some energy saving LED TVs in the market. Even so, OLED TVs are a lot more energy efficient, consuming about 40% less power than any latest LED TVs. That is again one of the strong points of OLED TV.
Which of the following terms describes the difference between white and black in an LCD monitor?
Contrast Ratio - This is the difference between the lightest and darkest spots that the LCD can display.
What is the reason that makes OLED TV need only little power to operate I heard that OLED TV uses less power than the other LCD TVs when compared What makes them so power efficient?
OLED TV works on pixel emission concept and not on the backlight concept. So it takes less amount of power as compare LCD TV.
What is the acronym used to describe the technology used in newer flat screen computer monitors?
Being unclear what you might be referring to it could be: LCD, LED, LCD-LED, OLED, etc.
Would an OLED display or a LCD display use more battery power and why?
because LCD Uses it to make 32 Bit 256 colors resolution
How slim is oled tv there was news about the extra thinness of oled tv is it really going to be thinner than lcd tvs?
The OLED TV can be the thinnest than any other TV technology. Samsung, Panasonic, Sony and LG are all preparing to release a range of OLED televisions with a thickness of as little as 4mm.
What is the difference between Plasma vs Lcd?
The difference between a plasma and widescreen lcd tv is that a plasma has less of a viewing range. They both have great video quality.
