Colour and Light: What is it about the LED TV?

LED TV Picture Quality You are walking through an electronics store looking for a new TV, and you come across a thing called an “LED TV”. Contrary to popular belief, a LED TV is an LCD TV. The difference lies in the backlighting method. In fact, the LED screens you see in shops are actually LCDs, and the term “LED” is the invention of Samsung’s marketing department. How do they get away with this? Typical LCD screens use a fluorescent backlight placed behind the pixels to light the image, red, blue and green colour filters are then used to create the colours you see on the screen. LED TVs, on the other hand, use LEDs as the light source, allowing for better control over lighting and dimming of the image. One would then ask why LCD screens need a backlight. Well as consumer technology, LCD has been in widespread use since the early 1980s where it was common in digital watches. As its name suggests, Liquid Crystal Display is a liquid that has been sandwiched between two plates, and it changes when a current is applied to it. While we have had black and white LCDs for years, colour LCDs are more recent, but the technology is the same. The Difference Between LCD and LED TV Just as you need to press a button to read a watch in the dark, and an LCD TV is no different. It needs a light behind it because it emits no light of its own. It is helpful to think of an LCD panel as a sandwich, consisting of different layers. On...

What’s The Difference Between LCD and LED TV

Difference Between LCD and LED TV There are so many different styles of TV on the market now that it’s hard to tell what you should actually buy to make sure you get the right TV for you and your house. We can address the difference between LCD and LED TVs and which one will work better for you in another article, but for now we are just going to discuss what makes them different on a fundamental level. LED stands for “light emitting diode”, which you may have some experience with in other areas. LED lights are common place in a lot of different areas of life, from the lights we string up at Christmas time to the flashlights that we keep in our trucks in case of emergencies. LED TVs use backlight to create the luminescent colors that we have come to expect from high quality TVs. Red, Green and Blue LED Lights combine their colors to produce an amazing range of other colors. The True Difference Between LCD and LED TV LCD screens are common place in the computer field and have been gaining large amounts of use in the world of handheld devices. LCD stands for “liquid crystal display”. There is a thin layer of liquid crystals in the screen that change their shape based on the electric current that is applied to them. This allows them to produce the pixels and colors that you need for high quality images to come through. Some LCD screens use LED lights for backlight, but the LED lights don’t actually produce the colors and the images. They only...

Know the Differences Between LED Televisions and LCD Televisions Before You Buy

The Difference Between LED and LCD TV by Pete Malcolm Before you buy a television, it is important to be aware of the new television technologies on the market to ensure you get a TV that meets your televisions viewing needs. Two television options you should learn about and know between their differences are LED televisions and LCD televisions.   LED TVs are the latest TV technological innovation to LCD TVs. LED TVs have the technological addition of light emitting diodes (LEDs) at the back of the TV which is known as back-lit, or they can have it around the outside edge of the screen which is called, peripheral. There are many benefits to the latest LED screens on the market. They provide improved contrast, better color depth, and deeper blacks which provides an excellent clear clean image on the screen. Most of the LED TVs are available in full high definition and they produce an improved brighter color image as well as sharper image than the other televisions With the LED TV, you get the advantage of blacker color blacks and much more vibrant colors. LED TVs are ideal for home theaters systems as they offer greater contrast ratio and real-life image quality. There are certain types of LED televisions available. They are the back-lit and edge-lit. LED back-lit TV permits dimming in specific areas of darkness in the screen which allows for true black and white colors at a higher contrast ratio and it does not negatively impact the bright objects on the dark background. The light of the edge-lit is distributed across the screen by a...

WitsView Estimates Global 3DTV Penetration Will be 19% in 2012

3D TV Market Global LCD TV shipments in 2Q12 to grow 8.4% QoQ; LED TV penetration rate to reach 70% in 2012 According to the Worldwide LCD TV Brands Shipment Report from WitsView, the panel research division of TrendForce, global LCD TV shipments in 2011 reached 200.5 million and is projected to reach 216.5 million in 2012 with an increased YoY of 8%. The brand vendors had been continuing to digest the inventory due to lackluster market demand and their conservative inventory stock-up amid the weak macroeconomics in past three quarters. However, the overall LCD TV shipments in 4Q11 performed well with a 15.1% QoQ increase, helped by the rebounded market demand due to year-end promotion in North America and product launches before Chinese Lunar New Year, encouraging the LCD TV brands vendors to be more aggressive on shipment in order to hit their annual sales target. On the contrary, the shipments in 1Q12 are estimated to drop by 24.5% QoQ and 2% YoY due to off-season and the concerns for new panel quality. The QoQ decline cannot be eased until the quality and mass production issues are solved; however, based on the current situation, with the upcoming May 1st Labor Day holidays in China, the shipment in 2Q12 is forecasted to rise by 8.4% QoQ as brand vendors are planning to postpone the demand for new models to 2Q12. Burrell Liu, WitsView research director, indicated that leaving past three diffcult quarters behind, the top 5 global LCD TV brand vendors’ attitude towards shipment turned aggressive and further enabled their respective shipments in 4Q11 to reach 18.5%; among which...

Aixtron warns of ‘extended downturn’ in LEDs

LED TV Demand To Fall? Aixtron, one of the two dominant providers of the metal-organic chemical vapor deposition (MOCVD) equipment that is critical for volume LED production, says that market demand is so weak at the moment that it cannot provide any revenue guidance for 2012 yet. At first glance, Aixtron’s 2011 results, with sales revenues of €611 million and a pre-tax earnings of €113 million, look solid enough. But the headline figures disguise a year of two distinct halves for the company, in which record-breaking sales in the first six months were suddenly halted by a collapse in orders from Q3 onwards. The German company’s CEO Paul Hyland told an investor conference call that any upturn was yet to appear in the opening quarter of this year, and that the industry was set to be plagued by overcapacity and price pressure until the next “wave” of LED adoption – for general lighting – emerges. Exactly when that will happen remains unclear at this stage. And although Hyland is confident that 2013 will mark the start of the era of solid-state lighting, things are set to remain tough until that happens. Unprecedented boom Between early 2009 and last summer, demand for MOCVD kit provided by both Aixtron and its main competitor Veeco Instruments had grown to unprecedented levels, driven initially by the rapid uptake of LED-backlit LCD televisions and then by generous subsidies provided by the Chinese government for LED makers in the country. Unsurprisingly, customers in China accounted for more than half of Aixtron’s revenues in 2011. But a combination of reduced consumer confidence, manufacturing overcapacity and credit tightening –...

US TV Buyers Opting For LED LCD TVs Instead Of CCFL

LED and LCD TV Sales By Richard Carlton • Monday, 27 February 2012, 10:50 pm GMT It has been revealed that for the first time ever there are now more television buyers in the USA who are choosing to buy LED-backlit LCD TVs rather than opting for cold cathode fluorescent lamp, or CCFL, technology. Whilst the latter has monopolised the market for many years, it is now considered old technology, and more and more tech-savvy consumers who demand high quality are opting for the LED TVs instead. US TV buyers opting for LED LCD TVs instead of CCFL The data came from the latest IHS iSuppli US TV Consumer Preference Analysis Report, which showed how the trend has shifted towards the newer LED backlight technology rather than the older CCFL. The survey entailed random polling of 45,000 households in the United States. The number of American consumers who decided from the word go that they were going to opt for LED-backlit LCD televisions increased to 54 percent in the final quarter of last year, reflecting a very sharp rise from the third quarter of the year, when this figure stood at just 22 percent. This increase means, of course, that the share of CCFL-based LCD TV displays has fallen, with the share plummeting from 56 percent down to just 25 percent. The data also revealed that out of the 54 percent who planned to buy an LED TV, all 54 percent actually went on to make that planned purchase. In addition to this, 81 percent of people who had planned to opt for the older CCFL LCD technology when...
