Comparing LED TVs with LCD TV Resolution
Posted by GuestPoster in High Technology on December 22nd, 2009
LED TVs are still really LCD TVs, but rather than using cold cathode fluorescent lamps (CCFLs) for lighting the LCD tv resolution they use LEDs. But even though they are similar in construction they have differing characteristics that you should be aware of.
Firstly the fluorescent lamps used in CCFL LCDs are always switched on or always lit. In order to display black areas on screen the light has to be deflected from the LCD panel so that it is not visible. However the methods employed to achieve this are far from perfect and so reproduction of very dark blacks is compromised and only relatively poor contrast levels are achievable (contrast level is the comparison between the level of blacks and whites that are possible).
With rear-lit LED TVs the lighting is provided by a matrix of LEDs situated behind the LCD panel. Each of these LEDs can be individually controlled and can be switched on or off. This allows for areas of dark (LEDs off) and areas of white (LEDs on) to produced on screen at the same time. When compared with LCDs, the reproduction of dark blacks is improved with rear-lit LED TVs and consequently so are the contrast levels.
Next when it comes to color gamut (or the range of color that is possible), the back-lit LED comes out on top. There reason for this is that rear-lit LED TVs use RGB LEDs which are able to produce a whiter light than either CCFLs or the white LEDs used in edge-lit LED TVs. This whiter light (or fuller spectrum range) enhances the colors that are displayed on the LCD panel and so improve the viewing experience.
If you are considering buying a new TV you should compare hdtvs before buying. To see the benefits that LED rear-lit televisions for yourself take a trip down to your local television showroom and view the improvements in contrast levels and color reproduction by comparing a conventional CCFL LCD model to a rear-lit LED TV and judge if the later comes out as the highest resolution lcd tv.
Refurbished iPhones Are As Good As New
Posted by whaleadmin in High Technology on July 19th, 2009
Many of the refurbished products like the iPhone have been returned because of sustaining minor damage during shipping or maybe just because the box was torn or damaged. If this is the case, they are then sent back to the factory, but in a brand new box and then sold as a refurbished iPhone. Most of the time the damage is very minor. When the iPhone is sold as refurbished, it has been fixed back to perfection, sold as top quality iPhones but at a discounted price.
Sometimes it is the case that the refurbished iPhone was a floor model or demo model in the store. They are then sold at a discounted priced just waiting for some music savvy customer to scoop it up with out scooping out money from his wallet.

Posted by whaleadmin in High Technology on July 18th, 2009
If you are tired of the wire jungle under your desk and you feel that you don’t have enough space for your feet to go with the huge metal box that is taking up what feels like half the foot space under your desk, perhaps it is time for you to consider getting anall in one computer. You may have noticed that your computer has been getting a little old and it is not really working as well as it did when you bought it. So perhaps that is not a bad idea, but what is an all in one computer? Well, this a computer that has all of it’s inards inside of the monitor. It doesn’t even need an extra box! This is great because it cuts down on cords and makes things a bit neater. Even the Cd tray is apart of the monitor. So if you are thinking about a new computer, give the all in one a look at.

Digital Image Spy Pens

One of the least used products in the spy pen market is the digital image spy pen. It sole purpose is to capture single snap shot images of its surrounding area, unlike other models it doesn’t contain any hardware designed to capture audio or video tracks and because of this finds its implementation and use somewhat limited.
However when the situation arises where it can perform its role it is exceedingly good.
Many people find it a handy devise to carry around on their person; it can be whipped out at any given time to get that all-important shot. Its disguise allows it to be taken into areas where cameras are not allowed and has allowed its user to take photographs of prototype products and private documents.
Wireless Security Camera and it’s Weaknesses
Posted by whaleadmin in High Technology on July 3rd, 2009
A wireless security camera in many cases misleads one to believe that the camera is a standalone unit with no cables required. The truth is, the most common wireless security cameras still need a power cable so there is still that aspect to deal with. And since it is often difficult to find an outlet for outdoor surveillance, you run into the same power supply problem as with any camera.
The range of a wireless security camera depends largely on the hardware itself. The transmitting and receiving antennas determine the amount of power the wireless signal has and how much obstruction it can penetrate. Obstructions to the signal include distance, but more disruptively thick walls and metal are the biggest enemies of wireless signals. Ideally, for maximum range in potential installation locations relative to your transmitter you want a clear, unobstructed path between the wireless security camera and the transmitter.

If you are really looking for the pinnacle in home entertainment systems then you really should consider setting up a home theater with an HD projector at its heart. The HD projector provides the picture quality of the HDTV but allows you to project the image onto a large screen or blank wall creating a cinema like experience. This coupled with a fantastic surround sound system can replicate the conditions of the movie theater in a way that few other pieces of televisual equipment can compete with.
Imagine sitting down with a drink and some popcorn and putting on your favorite high definition DVD. What could be more fun? And not only that, you can also attach a games console to the HD projector which means you can really get into those 3D role playing games.
