Πολύ καλό! Έπρεπε βέβαια να είχες ανακαλύψει 2 εβδομάδες νωρίτερα :) Όχι ότι θα άλλαζα επιλογή, πάλι τον q6600 θα έπαιρνα. Και τα συμπεράσματα που βγάζει το παλικάρι μου φαίνονται λίγο άκυρα

>ThermalTake SwordM πλέον στα ράφια του εξωτερικού

Λίγο καθυστερημένα αλλά το στέλνω για όποιον ενδιαφέρεται! :lol:
Έφτασε επισήμως και στο site της Thermaltake η νέα κορυφαία θήκη SwordM (δύο κλίμακες πιο πάνω από την Kandalf)

Οι πρώτες τιμές είναι περίπου $650 χωρίς υδρόψυξη
και $860 με υδρόψυξη....

>Εδώ τα φτηνά Mp3 players!

Σημαντική πτώση παρατηρείται στη σειρά MP3 players Sansa E200 , με το κορυφαίο μοντέλο στα 8GB να έχει τιμή 115 Ευρώ χωρίς ραδιόφωνο και 125 με ραδιόφωνο, σε κάποια καταστήματα αν ψάξουμε στο http://www.skroutz.gr. Οι αντίστοιχες παλιές τιμές είναι 175 και 200 Ευρώ.
Ο λόγος όχι τυχαίος αφού ανακοινώθηκε 10 μέρες πιο πρίν το νέο λεπτότερο και ανανεωμένο Sansa View με τα 16Gb να είναι στα 199Ευρώ ενώ να παίρνει κάρτα miniSD μέχρι τα 8Gb !

> Ήρθε το Intel X38 Chipset

για να υποστηρίξει τουλάχιστον μελλοντικά τους επεξεργαστές Intel Penryn, μνήμες RAM DDR3 και φυσικά PCI-Express 2.0, εκτός αρκετών άλλων καινοτόμων χαρακτηριστικών. Οι motherboard δεν πλησιάζονται και όλα αυτά είναι απλά μια πρόγευση για το τί θα ακολουθήσει. Προς το παρόν μένουμε στο chipset P35...

ένα άρθρο π βρήκα για τις OLED

OLED MONITORS

What flat panel screens were to CRT, OLED monitors will be to flat panels -- and then some. Imagine a display sharper, thinner, and less expensive than you can get from a flat panel monitor. They're still over the horizon, but jkabaseball gives you the lowdown on OLED's bright future.

CRT monitors were the first consumer monitor. They are big, but offer great performance. Then along came LCD monitors. They are a lot thinner, but priced higher. Their performance isn't great, and decent performance costs a lot more. Take Apple’s monitors for example, they are among the best in the industry, but can cost over $2000.

Now imagine a screen better than that, thinner than that, and even less expensive. Sounds too good to be true? With OLED technology making its way into screens, this is what we can expect. OLED monitors are still on the horizon, but smaller devices sporting OLED screens are starting to trickle down into the market. Let’s take a look at what OLED is and how we will benefit from them.

How OLED works

The name gives us a good idea of how it works, Organic Light Emitting Display (OLED). The basis of OLED was discovered in 1985, over a decade before the first displays were even seen. A Kodak researcher by the name of Ching Tang noticed that if you put an electrical current through an organic material, it glowed green. This is where the idea behind OLED came from. The company who brings you your film, oddly enough, owns the patents for OLED.

There are a few different types of OLED which I will explain in the next section. Basically there is a layer of material that will conduct an electrical charge. The charge is sent into the organic material, which creates the light and the color. Since the organic material creates the light, there is no need for a back light. There must be blue, red, and green light-producing organic material to produce the different colors of the monitor.

There is one major problem hindering all OLED displays. The organic material that is used decreases its brightness with the amount of time it is on. The time is measured from the beginning to when the brightness decreases to half its original brightness. The red and green material is up to at least 20,000 hours, while the blue is falling short by a lot. Last year is was at a mere 1,000 hours, and development for longer lasting material is slow. This means that the monitor will quickly shift to a yellow tint. This is the biggest problem developers have with OLED technology.

Image

The first OLED displays that will hit the market will be Passive-matrix. The first LCD screens were passive, and OLED will follow suit. They are fairly simple structures. They will be more expensive, and consume a lot more power than other types of OLEDs. They will be found in smaller devices with screens smaller than three inches, like MP3 players and cell phones. Passive-matrix is made up of a matrix of electrically-conducting rows and columns making pixels. Between the rows and the columns are the organic layers. On the other side is the substrate, the material which gives the electricity. The more current applied, the brighter the display.

What is going to be in most displays is Active-matrix. They will consume a lot less power than passive matrix. Active-matrix is like passive, but instead of rows and columns, there is a TFT back plate. This will control the brightness of each pixel. There will be two TFT arrays per pixel: one to start and stop the charging of the capacitor, and one to provide a constant electrical current to the pixel. This means that there will be a constant current at all times, so the overall electricity needed to light the display is considerably less than that of passive matrix.

Those are the traditional forms of screens we see nowadays. With OLED we will see new forms of screens, many that have only been seen before in movies. We will soon have the ability to see through our screens and bend them into any shape we want.

Image

Remember the “Lost in Space” movie (not the series)? In the opening seconds they are battling in space on space fighters. What is remarkable is that the screen is see through and mounted on the cockpit window. The pilot can see the computer screen and what’s happening on the outside at the same time.

Believe it or not, this technology is right around the corner. The screen with emit in both the top and bottom directions. It will be 70 percent to 85 percent transparent, roughly equivalent to a piece of glass. Active-matrix has an opaque substrate, so it is top emitting only. For transparent OLEDs, the substrate is transparent, so it emits the screen both on the top and bottom.

Transparent OLEDs will be just like the active matrix. The first use that popped into my head when I read about these was the wearable computer. I have seen a few prototypes of wearable computers, but none of them will take off until the screens become transparent. The computer aspect is set; the computers are small enough to wear. Once these transparent screens become available, look for a boom in the wearable PC industry. If you think talking on the cell phone while driving is bad, imagine using a computer while driving.

Image

The other new type of display will be flexible, meaning that you can bend the displays. Other forms of OLEDs will be thinner than current LCDs, but flexible OLEDs are going to be a lot thinner than even normal OLEDs. This will be great for mobile devices like cell phones and notebooks. They will take advantage of the thinness rather than the flexibility of the display.

The durability of this type of display will be much better than other forms of OLED displays. The problem with LCDs is that they aren’t too durable. Even a moderate amount of force can ruin a display. Flexible OLED displays will be more impact resistant and less breakable. You have heard of "rolling out a product" before, but these will literally be rolled out! They will be manufactured using a process called roll-to-roll (R2R). This is a very low cost way to produce OLEDs.

The U.S. government is helping to develop this type of display for the soldiers in the field. Flexable displays can be mounted onto helmet face shields for a "heads up” display. Alongside military displays, there are other uses for flexible displays, such as on automobile instrument panels.

In LCD displays, 90 percent of the backlight is absorbed to give the color. Using Phosphorescent OLEDs (PHOLED), nearly 100 percent of the electricity will be converted into light; this is four times greater than previously thought. This is an even newer type of OLED; the current OLEDs and the ones produced in the near future will not have this technology.

PHOLEDs will be even more vibrant, and offer brighter colors and longer lifetimes than OLEDs. This technology hopefully will find its way into passive and active matrix displays. What makes this different than most OLEDs is what it uses to portray the colors. Both of the red and green materials have lifetimes over 25,000 hours, but the blue is trailing behind at almost half the others; other blue materials are still under development. Blue material is a problem now, and looks like it will be in the future.

Conclusion

The future for OLEDs looks bright! For conventional displays, OLED will offer a better, clearer picture and lower power consumption. OLED technology will spread far; it will make new displays into previously undeveloped markets. We will see the emergence of transparent and flexible displays.

Transparent displays may finally bring out a useful wearable PC. They should look a lot like the ones that appear in movies. They should be as transparent as glass or plastic. Flexible displays will also come out in the future. These will be mostly used in mobile devices because they offer a smaller size and are more durable. There will be a few other applications for this flexible display that will use the flexibility of the display.

OLEDs are not without their problems. There aren’t a lot, but the lifetime is something to consider. The red and green organic materials are fine; they last roughly 20,000 hours and newer material will last 25,000 hours or more. The problem is the blue organic material. It doesn’t last nearly as long. Buying an OLED now will result in your buying another one real soon. Research is being done on the blue OLED, and progress is coming slowly but surely. The question is how long we will have to wait for the blue material to catch up. PHOLED research leads to the same result; the blue organic material still has a smaller lifespan than the rest. While OLEDs aren’t perfect yet, they still offer a bright future for displays.
