Types and functions of OLED or Organic Light-Emitting Diode TV

Let's go back to CES 2012 when it was presented the LG 55-inch OLED TV. That was an important day that has changed the way people watch TV and that gave the world the opportunity to enjoy breathtaking images, displayed in a quality never before experienced.

Now the OLED is a reality and the screen can get into our homes. But what are the technologies that allow this LG TV performance ever seen? How does this device work? OLED, what we mean?

OLED (Organic Light-Emitting Diode) panels emit light when electric current passes through them, the cells of an LCD, however, require a source of external light on the back. Because OLEDs do not require backlighting have a great energy efficiency, lower energy consumption and design exceptionally thin.

OLEDs boast images of superiority and unrivaled offer really deep blacks. The result, of course, is a better visual experience.

Add a white pixel all RGB and get better colors. 

There are two types of TV OLED viz:- RGB OLED and WRGB OLED. The latter technology is used in the OLED TV from LG. The difference between the two affects the overall viewing experience.

To form a color it must be used three (red, one green and one blue) mixed together. In this particular blend each one can have arbitrary intensity, from fully off to fully on. Adding a white pixel to the RGB system is obtained WRGB.

Increase the brightness and colors are more accurate. (Look below the balloons, the color displayed in the side WRGB is far better than what we find in the side RGB).

The colors are more natural.

Addition to the extra pixel white, LG has added the Color Refiner technology that improves the color displayed in this way on TV, which supports a wider range of colors, is so realistic and the natural world around us.

Less distortion - Greater viewing angle

The OLED coupled WRGB - Color Refiner then allows for accuracy and consistency of color from all angles. You can watch TV on the couch, lying in bed across the room ... from anywhere and without any distortion!

Now, the LG OLED is a reality and you know what technology you choose.

SAMSUNG GT-B5330, an economic smartphone

With both smartphone market it is not surprising that companies begin to diversify their products and offer variants for all types of customers. And for every budget.

As smartphones continue to dominate sales, its components are also cheaper and because of that companies can offer lower-priced versions.

Such is the case of the new Samsung GT-B5330, which seems to be a smartphone from lower middle class. As rumored, could lead the Android OS Ice-cream Sandwich. Also, incorporate a touch screen 320 x 240 pixels with a QWERTY keyboard to make it easier to send messages.

Regarding the technical aspect, it could incorporate a 849 MHz processor, 4 gigabytes of storage, WiFi, Bluetooth and a 2 megapixel camera.

Clearly, these specifications Samsung aims to provide an affordable phone with some interesting features, but well below what they offer today's latest smartphones. The new phone is meant to be released in some Asian countries.

With so much variety of models on the market, it is good to see that not only thinks of higher income levels and also takes into account people with lower purchasing power. With their cons and benefits, the new Samsung GT-B5330 is probably a good choice at a price much lower than you are accustomed.

Economic tablets, do they deserve punishment?

A high quality tablet, like the iPhone or the Samsung GalaxyTab is an option that any techie could want. However, not everyone can invest the money they cost, which is usually close to 400 euros, even surpassing them. Of course you can always find cheaper options.

On the one hand we have the 7-inch tablets. Apple has not yet been launched to put yours on the market (although it has been rumored on the output of an iPad Mini for months), Samsung itself. If the size is not a problem for you, then it is always a good choice for a high quality tablet priced a little cheaper.

Then there is the possibility of using lesser known brands. The quality is usually slightly lower, but often meet the needs of those who are not too demanding.

The question is, these tablets are worth economic or is preferable to the bank until you can buy a good one. Well, as always in regard to technological issues, depends on what you will give. Not the same check from time to time mail and online media to give a tablet professional use.

The truth is that a large number of tablet users only want to access email, read some ebook (but not very often) and get a web page. And for this with some of those found in the market for just over 100 euros is plenty.

Now if you take to stop all the possibilities offered by a tablet, it is preferable that we invest a little stronger.
