TV manufacturers can use an LED backlight instead of the Cold Cathode Fluorescent Lamps (LCD-CCFL) used in most LCD televisions. LCD-based televisions described as ‘LED TVs’ are different from self-illuminating Organic light-emitting diode (OLED) Casey Cizikas Jersey , OEL or AMOLED display technologies. In the UK, the ASA (Advertising Standards Authority) has made it clear in prior correspondence that it does not object to the use of the term ‘LED TV’, but does require it to be clarified in any advertising. There are several methods of backlighting an LCD panel using LEDs including the use of either White or RGB (Red, Green and Blue) LED arrays positioned behind the panel; and Edge-LED lighting Brock Nelson Jersey , which uses white LEDs arranged around the inside frame of the TV along with a light diffusion panel to spread the light evenly behind the LCD panel.


Compared to regular CCFL backlighting, an LED backlight provides higher brightness and improved color gamut. However advancements in CCFL technology mean wide color gamuts and lower power consumption are also possible. Cost is the principal barrier to wide use of LED backlighting on LCD televisions.


The variations of LED backlighting do offer different benefits. The first commercial LED backlit LCD TV was the Sony Qualia 005 (introduced in 2004) and featured RGB LED arrays to produce a color gamut around twice that of a conventional CCFL LCD television. This was possible because the combined light output from red, green and blue LEDs produces a more pure white light than is possible with a single white light LED. RGB LED technology continues to be used on selected Sony BRAVIA LCD models, with the addition of ‘local dimming’ which enables excellent on-screen contrast through selectively turning off the LEDs behind dark parts of a picture frame.


Edge LED lighting was first introduced by Sony (September 2008) on the 40 inch BRAVIA KLV-40ZX1M (referred to as the ZX1 in Europe). The principal benefit of Edge-LED lighting for LCD televisions is the ability to build thinner housings (the BRAVIA KLV-40ZX1M is as thin as 9.9mm). Others have also introduced Edge-LED lit LCD televisions with extremely thin housings.

Create Rss Feed For Your Website And Display Rss Feed Internet Articles | November 30 Anders Lee Jersey , 2009
Do you know that you can create RSS feed for your static website? But first, let's try to understand why you need to have an RSS feed.



RSS is the abbreviation for Really Simple Syndication. In the past, there is no way for a web visitor to get the latest content from a website. For instance, you know that a blog publishes new content on a regularly basis. But you are not sure when the content will be published since there is no fixed publication time line. If you want to know if new content is being published Anthony Beauvillier Jersey , you will have to bookmark the site and revisit the site manually to check for updates.


Obviously, checking for updates manually is very inefficient. By the time you see the content, it may already be old news. Of course, you can always depend on the search engines for the latest content. But even search engines have a timetable for crawling sites. In other words Cal Clutterbuck Jersey , you still won't be getting real time updates.


To overcome this problem, RSS is developed. RSS is content that is organized in XML format. That means instead of having your content displayed in HTML (which is for web browsers), links, page titles and summaries are published in a fixed format - the XML format. This format is very different from HTML. It doesn't bother with presentation. It's primary function is to deliver links. So if you have an RSS feed on your website Tom Kuhnhackl Jersey , that means anyone can grab your feed, and be updated on the latest links as soon as it becomes available.


RSS feeds are displayed in feed display aggregators. You will need one if you want the content of a feed to make sense to you. With an RSS aggregator, you can subscribe to any feed that you come across. As soon as there is an update, you will see the changes in your feed aggregator. You can configure your aggregator to check for changes in regular intervals. This works very much the same as your email software. For example Mathew Barzal Jersey , you can configure your email software to check for new mails every 5 minutes.


Now that you understand how it feed works, you can publish a feed on your own website to reap the benefits. How do you do that?


The quickest way to publish a feed is to use a CMS with a built-in RSS feature. For instance, if you setup a website with Wordpress, your site will have a feed automatically. You may then publicize your RSS feed on the Internet.


However Josh Bailey Jersey , if you are not using any CMS, you will have to depend on feed builder tools to publish XML feeds. Fortunately, there are free RSS builder tools online. Here is how it works.


Enter the URL of your static website into the RSS builder. You will then be asked to select the links that will be included in your feed. Once you are happy with the preview, you can generate the feed. You may then promote the feed URL on your own website.
