Lcd Versus Led Hdtv Which Can be Improved

Producers like to industry their HDTV models as either LCD or LED models. The fact in the matter is both kinds of televisions use the identical technology, but there are differences major enough to create them various classifications. During the holidays and nicely into January, buyers acquire televisions and should have the facts necessary to buy the kind of tv to meet their desires. Following is often a comparison and contrast of LED and LCD HDTVs.

The important part of LCD technologies, liquid crystal diode, is existing in each models. Nonetheless, there are subtle variations among the 2. LCD televisions are likely to have darker pictures due to gentle becoming blocked from the LCD panel. LED, however, makes use of back-lighting alongside the edges from the screen to assist brighten those darker places, thereby generating a brighter and improved quality image. Lately one manufacturer built in an solution to turn off the back-lighting, although scientific studies display picture quality was improved with this function on.

Aside from the above-mentioned variations in back-lighting, there truly are not any important differences among the LCD HDTV and LED HDTV designs. Both televisions have great picture top quality together with superior color displays. With that said, it must be pointed out that LED televisions with RGB color lights or perhaps a colour wheel to impact the back lights, LCD models are a little edged out from the LED’s technologies within this area.

Viewing angles on both varieties of televisions will differ based on the thickness of the glass used for the display screen. Each LCD and LED designs have been identified to transform this location of manufacturing specs usually, so it is not a significant level of comparison among the two kinds of televisions. You’ll find other qualities apart from this one to base an correct, degree comparison on.

A further point of comparison among the two sorts of televisions is video playback and gaming attributes. Every tv does present a mode for the online gamer that helps make it convenient to hook in almost any sort of playing program. Also, each designs are whilst far as playback and picture refresh rate. Even though LED televisions don’t have considerably of the item history over the open up market, it has been revealed that LED again lights have a tendency to last longer, theoretically generating them the much better tv. CFL phosphorescent back-lighting does tend to be additional unstable and will degrade at a faster price.

In conclusion, while both models appear to become pretty even in all locations, LED will a little bit edge out the LCD designs in longevity.

4 Major Labels Preparing New Digital Album Format

Four of the major labels in music industry are teaming up to lock horns with Apple Computers, in a bid to achieve commercial success and resuscitate the industry. Sony Music, Universal, Warner, and EMI are working on a new format for music albums, called CMX, in an attempt to compete with the forthcoming Cocktail Project, to be launched soon by Apple. Files created in either of these formats will contain not only music, but also artwork, lyrics, videos, and liner notes, all within a single file. If either of these formats catches on in the market, one can expect to bid goodbye to popular formats prevalent now, including WAV, M4A, and yes, even MP3.

According to news published in the Times, CMX format developed by the 4 major labels was rejected by Apple straightway. Soon afterward, Apple started to work on an in-house alternative, monikered Cocktail. It is unclear how the two formats will differ according to functionality. The only difference will probably be in ownership of the formats.

A representative from one of the four labels told the Times, “Apple at first told us that they were not interested, but now they have decided to do their own, in case ours catches on. Ours will be a file that you click on, it opens and it would have a brand new look, with a launch page and all the different options. When you click on it you’re not just going to get the 10 tracks, you’re going to get the artwork, the video and mobile products.”

However, all this effort by the labels may go in vain, if the CMX format is not compatible with iTunes, which is still the default music software for iPhones, iPods, and Apple Macintosh Computers. Apple is more concerned with keeping sales of hardware up, while the labels undoubtedly have boosting sales of music albums as their target. Apple is rumored to be all set to launch a new tablet PC this fall, which will also ship pre-installed with iTunes.

The four labels plan to release CMX file (which is so far just a working title for the new format) in November. It will be “soft launched”, that is, released on an experimental basis, with just a few releases. An industry source commented, “We are not going out in force. What you are going to see are a couple of releases thrown out there to see what people like. We are working with the retailers now.”

With the Coming of iPhone 5 iPhone 4 Still Attractive

Till now, Apple has not announced any relevant information about iPhone5 in adavance. In fact, it doesn’t mean Apple will delay the release time of iPhone5. Maybe they are making full use of the last time to add more feature to iPhone 5, and keep it for a time in suspense. In any case, while the major manufacturers have recently introduced their new products, under such pressure, Apple would never like a rat in a hole. We firmly believe that iPhone 5 is approaching. Of course, with the coming of iPhone 5, the further price cuts for the forth generation of Apple is the general trends of cell phone lcd screens. According to the latest news, the latest quotation of 16G Apple iPhone4 Hong Kong version of is only 4580RMB. If you want, just cosider buy it.

In case of its performance, Apple iPhone4 is equipped with A4 processor clocked at 1GHz, behind which is embedded 5-megapixel camera, support for 720p video recording and cell phone signal jammer. There are also integrated Bluetooth, GPS, WIFI, SyncML and other functions to support electronic compass and accelerometer applications, etc. It is very easy to operate and user-friendly.

Compared with Apple iPhone 3GS, iPhone4 has changed dramatically in its appearance and become more fashionable; The thickness of its body is only 9.3 mm, using a 3.5-inch IPS LCD screen with the resolution of 940 ?? 640 pixels, and increased four times pixels compared to the old resolution of 480??320 pixels, quite clear and vivid display. In case of its hardware, it is equipped with 1GHz processor and 512MB memory, run faster, more efficient and can support iOS 4 system.

The price bubble of Apple iPhone 4 blew out. Apple’s prices have dropped back the normal price for the being time. I firmly believe that there is not so much room for the price cut of iPhone 4 before the release of iPhone 5. Just like the same case, even now there is still many people to choose iPhone 3GS, which has quite high performance cost ratio. So you could cosider purchasing your ideal iPhone at present.

Apple iPhone4 has become increasingly popular around the world. And the full version of iPhone 4 start to cut down the price. However, I believe that many Apple users have been waiting for the arrival of the Five generation of iPhone, and iPhone 4 is not so attractive.

Nokia Mobile Wallet Service to go Pan-india by 2012

JOINING THE fray of introducing the mobile wallet service after popular mobile service provider Airtel, is Nokia. The mobile handset manufacturing company, which in terms of saleability, is the largest in India, is now contemplating to extend its services throughout the sub-continent by early next year.

Speaking on the sidelines of the launch of Nokia X1-01 and Nokia C 2-00 in the Andhra Pradesh market, officials said that by 2012, it (Nokia mobile wallet) will become a pan-India product. The focused market is semi-urban and rural markets and also below-average income urban markets.

Currently, the Nokia mobile wallet facility is available in Delhi NCR, Chennai and Pune and has forged an alliance with the Union Bank of India and Yes Bank. However, the company is in process to get in talks with other major banks, which have got a pan-India presence.

The Nokia mobile wallet features come embedded with the Nokia X1-01 and the C 2-00 mobile phones, and interestingly is the only brand in the market that provides this facility with its partner banks. So far, it is just mobile service provider companies such as Airtel, Vodafone and Reliance that has initiated this service.

However, the service will be categorised into two categories. Customers who do not have sufficient identity proof will be categorised under the no-frill account in, which the daily transaction limit will be specified apart from having maximum cash limit. Under the no-frills account, in compliance with the RBI guidelines, the customer will get a limit of Rs. 50,000 maximum, and daily transaction limit of Rs. 5,000.

Beyond The Basics Of Thin Film Deposition Control By Quartz Crystal Monitor

Thin Film Deposition is a vacuum technology for applying coatings of pure materials to the surface of various objects. The coatings, also called films, are usually in the thickness range of angstroms to microns and can be a single material, or can be multiple materials in a layered structure. Physical Vapor Deposition (PVD) is a common class of techniques for this and includes Evaporation from a heated source. This paper discusses principles of Thin Film Deposition thickness and rate control by use of quartz crystal monitoring. In particular it will go beyond the basics into topics including co-deposition and multi crystal systems for PVD by Evaporation.

The key concept behind this type of measurement and control is that an oscillator crystal can be suitably mounted inside the vacuum chamber so that it receives deposition in real time and is affected by it in a measurable way. Specifically the oscillation frequency will drop as the crystal’s mass is increased by the material being deposited on it. To complete the measurement system, an electronic instrument continuously reads the frequency and performs appropriate mathematical functions to convert that frequency data to Thin Film Deposition thickness data, both instantaneous rate and cumulated thickness.

Such sensors and instruments are readily commercially available, including in various integrated models that not only read and display the rate and thickness data, but also provide outputs for Thin Film Deposition system control functions. Features vary by model, and you need to be sure to get one that has the features you require, but many can handle multiple independent crystal oscillators and some can also control multiple simultaneous sources.

The most common Thin Film Deposition systems have only a single source operating at one time, although such things as a multi pocket E Beam sources can have several different materials available for sequential selection and usage to make a multi layer film. And with only one material being evaporated at any moment, there is usually only a single crystal sensor, although it may be special type of sensor head that holds more than one crystal so a spare is ready if one fails during the run. But there can be times when it is necessary or desirable to position multiple crystal sensors around the chamber and average their signals for better control.

A good example of this would be a material that sublimates rather than melts – like dry ice, it just goes from solid to vapor inside the vacuum chamber without becoming liquid. Especially with larger size pieces of source material, such as chunks of silicon oxide, and an E Beam sweeping across them, there can be significant directivity to the vapor stream and it can change from moment to moment. Since the substrate holder normally rotates during the deposition, the substrates themselves can still come out reasonably uniformly coated as this vapor directivity is averaged out. But a single crystal in a single fixed location only sees the vapor at that point and does not get the benefit of averaging.

And this crystal is, in effect, “driving the bus”. When it thinks the proper thickness has been achieved, it will close the shutter and stop the Thin Film Deposition process, and the substrates have little likelihood of having achieved the same average thickness. So run-to-run repeatability can be very poor and quite frustrating. The solution to this problem is to have several crystals mounted in different location and take signals from all of them and average them out for the control function. There are controller models that can do this.

Even a single crystal has details to attend to, such as calibrating its thickness readings. It can, of course, only “see” the Thin Film Deposition that lands directly on itself, which is not what a user wants to know or to control. The user wants to know what is on the substrates, so physical measurements need to be made to compare to the crystal reading and a calibration factor (normally called “tooling” factor) needs to be calculated, programmed into the instrument, and then verified. With multiple crystals, this needs to be done for each of them, and there may also be the option of “weighting” them so that one sensor is counted on more heavily than another.

Although not nearly as common as single material layers, it is also possible to perform co-deposition where two sources are simultaneously operated to create a blended layer of two materials. There are inevitably some tradeoffs being made in such a system. You can have, for example, two E Beam guns in a chamber, but they cannot both occupy the exact same physical space. They cannot both be in the “perfect” position in the center of the chamber, and that becomes a Thin Film Deposition equipment design consideration. But, for co-deposition control, each source needs to have its own crystal sensor, and, ideally, neither sensor should be able to “see” the other source. If it did, there would be cross talk between the two and loss of control accuracy.

So the sensor mounting should include any necessary physical shielding on the sensor heads so that each has a good clear line of sight to its intended source but no line of sight to the other source. You also generally want to have some shielding between the sources themselves to avoid material cross contamination, and for E Beams, you also need to avoid magnetic interference between guns. But those source aspects are not really part of this paper and will not be discussed further

Once you have all of this taken care of, a suitable chamber with two sources and a suitable crystal control system with the right capability, co-deposition has some important considerations in terms of film programming. Although it is conceivable a user might want to do some unusual layer blending of material A and material B, the most common case is a simple ratio such as 50:50 or whatever through the entire layer, and we will discuss that case.

It is quite possible that the pre-conditioning phase will be different for the two materials, different ramp and soak settings. But remember, if you want both source shutters to open simultaneously in order to have co-deposition at the start of the layer, the duration of the pre-conditioning phase does need to be the same for both. The power levels can be different – no problem. But the total time needs to be the same or one shutter will open before the other and your film will begin in single material mode rather than co-deposition.

You also need to know what you really want your thin film material ratio to be including whether it is thickness based or mass based. The crystal controller is normally all thickness based, so if you want mass instead you need to take that into consideration. And you need to maintain the same rate ratio throughout the process as the final thickness ratio, or the shutters will not close together at the end and the co-deposition will cease when one closes.

Regardless of process type, though, single layer, multi layer, or co-deposition, there is always the potential for a crystal failure during a Thin Film Deposition run. Some models of sensor head hold one or more “spare” crystals and can automatically switch to a new crystal if one fails during the run (if the function is also supported by the controller). Otherwise, there are usually a couple of basic choices that can be made in the controller’s program: abort or complete the layer in “time-power” mode.

What this means is that the controller would take the last known data point – what was the power drive level and the deposition rate and the cumulated thickness at the moment the crystal failed – and just blindly maintain that same power drive for however much longer it would take at that same assumed constant deposition rate to reach the programmed final thickness and then close the shutter. If the power and rate have been fairly stable, this can work well. If they have been unstable, varying wildly, it is a real gamble

It is, of course, a user choice, and various factors should be considered such as whether stopping (aborting) at this point would necessarily mean scrapping all the substrates. In that case, it might be better to take a chance on “time-power” rescuing them.

There are many more aspects of quartz crystal monitoring and control of Thin Film Deposition, and instrument user manuals can provide a great deal of additional information. But quartz crystal control is a highly useful PVD technology and we hope the information presented here will be of help.
