LED (Light Emitting Diode) WHAT?
Light-emitting diode, current passes through the tiny devices that produce light. Energy use more efficient light bulbs and much more durable. Moreover, produce more heat lamp wire and do not need to work. In addition, the continuous black light to create pixels in the image that needs polishing liquid crystal screens (LCD) and consume much less power. LEDs, be aware that we, already entered into our daily lives: acetylene lamps, digital clocks, remote controls, some of them.
So the "O" WHERE IS COMING?
O'su OLED, organic means. Organic, carbon-based layer, the two conductors (an anode and cathode) are compressed between the enzyme, called and supported the main substance. When electric current passes, makes the light source of production. A non-organic LEDs, are sandwiched between two conductive layers are not flexible, that is, why there are high organic carbon-based LEDs. Because OLED'lerdeki organic layer, the razor-thin, ultra-light, super bright and flexible. This is OLEDs, flexible screens, bright and clear as crystal displays, TVs, or transparent device to be used means that many incredible.
AN OLED TELEVISION, LIGHT AND HOW Creates an image?
"An OLED display, pixels, or one by one, taking advantage of the on-screen elements produce their own light, he" is in the form of audio technologies, Sony's answer to this question the department director, Peter Hainsworth. "OLED will appear on the screen or the color of the light needed to produce enough energy to power output. So, to get an all-white image using the maximum power, black power is not used at all for the image. One LCD'deyse black light is always open. "
Each OLED has many different types designed for a specific application. Sony (www.sony.com.tr), the highest level of image-producing light-emitting OLEDs tend to use and very bright. This is OLEDs light, sandwiched between two conductive reflector bounces back and kicked in enzymes and thus produce an image is very bright. OLED is a type of transparent, allows light to pass through the device and transparent so that images can be displayed.
HOW TO HAVE A SIMILAR NATURE OF THE ORDINARY ÜSTÜLÜĞÜNÜN OLED?
Organisms such as fireflies, a biochemical reaction (chemical oxidation) due to produce their own light. In OLED, after passing an electric current produces its own light. "In other words, reach the same conclusion in different ways. But OLED roots firmly depends on the natural world. "Hainsworth said.
WHAT CAN BE DONE OTHER OLED'LERLE?
This list is too long. Transparent OLED prototypes produced by companies such as Samsung, staring at the screen makes you feel like izlermiş a window appears on the images. This technology is used in cars is reflected in the navigation system allows the windscreen. In this way, drive, go out and easily accessible route to follow. Hainsworth showcases this system can be used at the same time, as reflected in the glass showcase ads, says the customer can be achieved görmesinin products sold in stores.
Sony and Samsung, many trade show (the Consumer Electronics Show is one of them) has already begun showing prototypes of flexible display. You can find a clip on YouTube about it. (Http://git.pcnet.com.tr/121)
Flexible screen feature is extremely encouraging that the creativity and innovation. For example, these screens are television screens so that clothing is available and can reach a whole new level of portability. Foldable, rolls and made a holiday with you can sneak in a bag. General Electrics (GE) has already inspired by bands OLED rolls for the production of newspaper production. (Http://www.grcblog.com/?p=247) "Imagine the illuminated wall papers," he suggests, Research, General Electric (www.ge.com / research).
OLED DO YOU HAVE ANY ADVANTAGE?
OLEDs, bright light capable of producing much more than other screens. A typical flat-screen TV, 50,000:1 contrast ratio. around. This is the dark and bright parts of the screen between the measure of dynamism. However, Sony 11 "Bravia TV XEL-1 OLED 1,000,000:1 contrast ratio." Dir. "This is just a figure, but when you look at the photo that appears on the screen, the reality is very extraordinary." As Hainsworth claims.
OLED screens are also incredibly lightweight: only 2 kg of the weight of Sony's television. In addition, the LCD has a much wider viewing angle (about 170 degrees). This is by obtaining a clean image, the screen can escape the farthest distance as a measure of the circular.
OLED DISADVANTAGES OF WHAT?
Currently, the biggest disadvantage of OLEDs, the production is very expensive. Cause not yet been adopted for mass production. Good thing is, set displays, fast and efficient ways of production, the news that the price would drop rapidly. Although this speed, depending on the demands of the future, though, worth the wait.
OLED DEVICES ALREADY SOLD
Now in the market for OLEDs is limited as production costs are very high. But thanks to a very low power consumption of mobile phones, digital cameras, MP3 players and other portable devices are extremely useful for the obvious.o
