A quick guide to… AMOLED

You may have noticed the word AMOLED appearing in descriptions of new mobile phones, such as the forthcoming Nokia N8. But what is this new technology, what problems does it help to solve and why is it a desirable thing to have? Here’s our quick five-minute guide to what AMOLED is and why you might want it on your next phone.

There are two main areas on your mobile phone that eat through your battery power like it’s going out of fashion; the display and the transmitter and receiver. Phone manufacturers have succeeded in reducing the amount of power the transmitter/receiver uses and now they’re focusing on the display.

When screens were small, the amount of power the display used wasn’t so much of a problem, but now screens are getting larger, the amount of energy they use has become critical. Reading web pages and watching video on a big 3-inch+ screen eats through power, especially if you’re using it in a outdoors where you may need to increase the brightness.

AMOLED displays consume less power than traditional Liquid Crystal Display (LCD) and Light Emitting Diode (LED) mobile displays, plus they’re also faster, and the colours are more natural.

AMOLED is short for Active-Matrix Organic Light Emitting Diode (AM-OLED) and, as it says in the description, it’s a type of LED. The display is built up of four layers: a cathode layer, an emissive polymer layer, a conducting polymer layer and an anode layer, and when a current is passed through the layers, the polymer layers give off light.

However unlike conventional LED screen technologies, AMOLED displays do not require a back light, which is the part of a normal mobile display that uses the most power. Hence, AMOLED displays use a fraction of the energy of existing technologies.

Additionally, AMOLED displays are created by depositing organic compounds on a flexible plastic base (substrate) rather than the conventional silicon substrate. The advantage of using plastic is that the amoled display is thin, lightweight and rugged, unlike silicon which many mobile users know to their cost, is brittle, and easily broken.

One of the future uses for AMOLED is in foldable or roll-away displays. Those futuristic roll-up displays that we keep seeing on sci-fi films like Minority Report are just around the corner. The display engineers are working on them right now, and at some point in the next 5-10 years they will be appearing on your mobile phone.

Nokia 5250 Full Touch music phone will Rock soon

Nokia set rumours flying a couple of weeks ago when pictures of an as-yet unreleased device were inadvertently uploaded to the Ovi Store. Well, now it’s officially launched – the Nokia 5250 is a touchscreen, music-centric device aimed anyone seeking a modern, multipurpose mobile that also offers great value for money. Read on for pictures and specs.

The device comes with a music player on the home screen and tracks can be downloaded from Ovi Music or your own collection. There’s 51MB of memory on board, but audiophiles can expand this to up to 16GB with a microSD memory card – enough space for 4000 songs. The device also offers an FM radio. Topping off its musical credentials, the 5250 comes with a free copy of the acclaimed Guitar Hero 5 Mobile: this is a phone that invites you to rock out while you’re on the move. The Nokia 5250 will ship with the all-you-can-eat music offering, Ovi Music Unlimited, in selected territories.

This is a highly sociable phone. Also on the home screen, you’ll find your favourite contacts and there’s easy access to Facebook, MySpace and the rest. You can also log-in to multiple email accounts such as Ovi Mail, Gmail and Yahoo! Mail, as well as instant messenger accounts from all the usual suspects. Extra applications can, of course, be added using the Ovi Store.

Battery life is also excellent. The device will last up to 18 days in standby or up to seven hours talktime. If you stick to music, then it can play for 24 hours without stopping.

The 5250 runs the Symbian^1 operating system and offers GSM/EDGE communications over four bands and GPRS for data. It has a 2.8-inch TFT screen with a 16:9 apect ratio and a resolution of 640 x 360 pixels. On the back, there’s a 2-megapixel camera, with Ovi Share installed to let you upload your snaps to the Web. Eminently pocketable, the device measures 104mm x 49mm x 14mm.

Before taxes and operator subsidies, the Nokia 5250 will cost just €115 and is expected to ship in the fourth quarter.

Pocketbook announces color touch screen Android powered e-reader and more

Manufacturing upstart PocketBook is clearly still gung ho about e-readers, judging by the five new models it has announced will be released at IFA in September, which include a pair of entry-level ProBook 602 and 902 units, as well as the ProBook 603 and 903 premium units. The 60x designated models sport 6-inch screens, while the 90x models have a bigger 9.7-inch. All models will feature 2GB of internal storage, a Linux-based OS, and include WiFi and Bluetooth connectivity. However, the higher-end versions also gain 3G connectivity and a Wacom touchscreen. More interesting and genre-bending though is the so-called "entertainment model" PocketBook IQ that will be available in three case color options, feature a 7-inch TFT color touchscreen, WiFi, Bluetooth, and will run Android 2.0. Access to PocketBook's own Bookland.net e-book store unfortunately rounds out all the details we know so far, but we'll be sure to find out more once IFA gets going.

ஸ்மார்ட் போன்கள் மூலம் மொழி தடைகளை உடைக்கலாம்!!!
[ வெள்ளிக்கிழமை, 20 ஓகஸ்ட் 2010, 07:53.17 பி.ப GMT ]


ஸ்மார்ட் போன்களிலேயே இயங்கும் real-time மொழிபெயர்ப்பு தொழில்நுட்பத்தை உருவாகியிருக்கிறார்கள். இதைப் பற்றி தான் இந்த பதிவு.
தீவிரவாதத்திற்கு எதிரான போர் என்று அமெரிக்கா ஈராக்கையும், ஆப்கானிஸ்தானையும் பிடித்த பிறகு அந்நாடுகளில் அமெரிக்க படையினருக்கு மொழிப்பிரச்சனை பெரிதாக வளர்ந்தது. சோதனைகளின் போது சைகை மொழியிலேயே பேச வேண்டியிருந்தது. இது மிக பிரச்சனை மிகுந்ததாகவே இருந்தது.
இச்சிக்கலை தீர்ப்பதர்க்க்காகவே TRANSTAC தொழில்நுட்பத்தை உருவாக்கியதாக கூறுகிறது National Institute of Standars and Technology (NIST). TRANSTAC மொழிபெயர்ப்பாளர்களின் தேவையை நீக்குகிறது. ஆங்கிலத்தில் பேசுவதை speech recognition தொழில்நுட்பத்தின் மூலம் புரிந்து கொண்டு txt file ஆக சேமிக்கிறது. பின் இது தேவையான மொழிக்கு மொழிபெயர்ப்பு செய்யப்பட்டு பின் ஒலிக்கிறது. பின்னர் மீண்டும் இதுவே அக்குறிப்பிட்ட மொழியில் இதே போல் மொழிபெயர்க்கப்பட்டு ஆங்கிலத்தில் ஒலிக்கும். பேசும் சொற்றொடரின் நீளத்திற்கு ஏற்ப மொழிப்பெயர்ப்பு வேகம் 2 அல்லது 3 வினாடிகள் வரை எடுத்து கொள்கிறது.
இதற்கு தனிக்கருவி எதுவும் இல்லாமல் ஸ்மார்ட் போன்களிலேயே பயன்படுத்த முடியும் என்பது இதன் சிறப்பு.
