Nokia 447Za Opens More Windows for Less Energy
September 15, 1997
Computerised information becomes visual on the display. Processing of increasingly sophisticated visualised information plays an important role in the works of professional employees and independent specialists as diverse as secretaries, controllers, corporate planners, engineers, accountants and marketing personnel. Nokia’s new 447Za display enables the professional PC user as well as the demanding home user to enjoy the full potential of their IT environment. Thanks to its advanced CRT, this 17-inch display consumes appreciably less power than ordinary 15-inch displays.
The user upgrading an ordinary 15-inch monitor to a Nokia 447Za gets an essentially larger screen. The image resolution of the Nokia 447Za is 1024 x 768, as against 800 x 600 for a standard 15-inch monitor, an increase of over 60 per cent. At the same time, the Nokia 447Za consumes less power than a 100 watt light bulb. A corporate customer with a large number of displays in daily use can save substantial sums of money in the electricity bill by replacement of standard 17-inch displays with the new Nokia displays.
Improved Picture Quality
Higher resolution increases the amount of information displayed on the screen. The increase can be either by way of more accurate graphic information or a larger amount of simultaneously displayed information. The benefits for the user are straightforward. The engineer derives more accurate visual information from his graphs. The secretary prepares a set of slides with greater ease. The controller can work with more windows of financial information.
The Nokia 447Za provides the user with a sharper picture thanks to the feature known as dynamic focus. Dynamic focus adjusts the picture for the difference in the length of the electron beam between points at the centre and at the corners of the picture. As a result, the user can work with a picture that is in focus from corner to corner.
Saves Power and Money
The power savings offered by the Nokia 447Za can be readily quantified. If a corporate customer has one thousand displays in 8-hour-full-time use, replacement of 120W displays with Nokia 447Zas results in an annual power saving of 40 MWh. If the displays to be upgraded consume 140W, the saving is 80 MWh. If the upgrading is from 150 W displays to the Nokia 447Za, the annual power saving amounts to 100 MWh.
The monetary saving depends on the local electricity price. The higher the electricity price, the larger the saving. Electricity is relatively expensive in Germany, with users paying USD 126.1 per MWh. A German corporate customer with one thousand displays in full-time use, saves USD 5040 in upgrading 120W displays to 100W displays. For a 140W to 100W upgrading, the corresponding saving is USD 10 090. For a 150W to 100W upgrading, the saving works out at USD 12 610.
Audio Future Built-In
Built-in audio capabilities come standard with the Nokia 447Za. They comprise a stereo amplifier with two 5 watt loudspeakers and a directional microphone. The built-in speakers and microphone save desk space and eliminate the constant problem of trailing wires.
The audio capabilies come into their own with the demanding home user. They also point to the future of diverse multimedia applications in office and other business environments. Telephone calls can already be routed via the Internet. Software transforming speech into writing already exists. It is safe to predict that speech will play an important part in the development of desktop communication in a world of IT networks.
