Flat Panel Displays - Beyond Plasma

The term set-top box will become something of a misnomer in the near future, as most displays will become too thin to allow a box to placed on top of them. As the price of plasma & LCD displays has plummeted and their image quality has improved, they are popping up in homes everywhere.

Although they are the darlings of the media and the generic for flat panel display in the minds of many, plasmas are about to be in a serious fight with other technologies for the flat panel crown.

LCD displays, seen on the desktop for years as computer monitors, and commonplace in smaller flat panel TVs, are finally increasing in size to the point they are becoming a rival to plasmas in the 42" 50 size range. Picture quality is similar to plasmas; however LCDs are immune to the burn-in that can affect plasma displays. This burn-in occurs when plasma units are used to display static images such as video game screens and stock or sports tickers.

Plasmas generally have an edge in the ability to produce deeper blacks and more saturated colors than LCDs. Plasmas are also better at producing full motion video than LCDs because of the response time of the LCD panels, although this difference is disappearing.

LCD TVs are a bit more expensive than plasmas at 42" and larger sizes, but they should last a while longer. Plasma displays should last 20,000 25,000 hours and LCDs should give 30,000+ hours of useful life. However, the latest generation of plasma displays from NEC, LG & others is claimed to have a 60,000 hour life. If that is an industry trend, the traditional lifespan advantage held by LCDs may soon disappear. This comes at a time when Sony and other major consumer electronics manufacturers are either abandoning plasma or reducing their plasma offerings. Others, such as Panasonic, Fujitsu and Pioneer are firmly commited to Plasma technology.

Currently Sony has a 42", NEC a 40", Sharp a 45", and Samsung a 40" LCD TV or display. Samsung also has the big one, a 46" that started shipping in early September of 2004. The Samsung 46" was the first consumer LCD video display to have a 1080 line native resolution. This allows it to display 1080p native when that format arrives for HDTV. The Samsung has been joined by Sony, Toshiba and others, to endow the mid 40" size category with some pretty solid LCD offerings. The largest consumer LCD TVs or monitors are the Sharp 65" and Sony showed a prototype 82" LCD from their Bravia line at the 2006 CES in Las Vegas.

Other technologies are on the horizon as well. One that has shown great promise is OLED, for Organic Light Emitting Diode. Developed by Kodak and Pioneer, this technology has been used for a few years in car stereo and cell phone displays. It's just about ready for prime time. Philips has shown a 13" unit, Samsung a 17", and Seiko-Epson has shown a 40" prototype.

OLEDs advantages are many. It actually emits its own light, so it requires no backlight and has better contrast than a traditional LCD. OLED displays have a wide viewing angle like a plasma display. Power usage is very low, less than 1/2 that of a traditional LCD display. At around 2mm deep, OLEDs are much thinner than either a plasma or LCD.

They have a refresh rate about 1,000 times faster than a traditional LCD, so they will be far superior for video applications. They have fewer parts than LCD or plasma and can be manufactured using a novel ink jet printing process. This promises to keep prices low as the technology is implemented. It is expected to see sub 20" displays in stores by 2006 with larger units following one to two years later.

Other promising display technologies on the horizon include SED (Surface-conduction Electron-emitter Display) and carbon Nanotube. SED was developed by Canon, who began research into the technology in 1986. SED is basically the same principle as CRT, however there are important differences. The most important from a consumer standpoint is thickness. An SED display is only an inch or two thick, depending upon screen size.

The basic construction is two glass plates separated by a vacuum. One of the plates is coated with phosphors the other is mounted with electron emitters. Electrons are ejected when a voltage of about 16 to 18 V is applied to the emitters. These electrons are then accelerated by a higher voltage into a beam similar to that in a CRT display.

The visual advantages of SEDs are as for CRT displays, great color, deep black levels and quick motion response. These advantages, combined with the slim form factor, low cost and small power requirement should make for a real winner.

A unit shown by Toshiba at a Japanese trade show in April of 2005 even had its contrast ratio up to an incredible 100,000 to 1 by significantly reducing black luminance. Even if the specs were a bit inflated this would still amount to a fantastic contrast ratio, on the order of 5 times that of a traditional CRT. At one time, Toshiba indicated they would move to this technology for all displays over 40 by 2006. However, after a spectacular demo at 2006 CES by where they indicated a late 2006 debut, both Canon and Toshiba, Toshiba resheduled their release date for SED until mid 2007, ostensibly to allow them to produce lower cost SEDs.

There is another fly in the SED ointment too. On April 21st, 2005 US firm Nano-Proprietary has filed a suit against Canon in the U.S. District Court of the Western District of Texas, alleging that the surface (SED) televisions that Canon plans to release violates a licensing agreement signed 5 years ago between the Japanese giant and Nano-Proprietary.

The pace of change in the home theater and entertainment display market has just kept accelerating. There are some promising technologies around the corner that will allow, as usual, higher performance, lower cost and more compact form factors. As prices for advanced technologies plunge and technology improves, it will make it even easier for the average person to have a fantastic media system almost anywhere in their home.

Five Fundamental Steps To Successful Stock Option Trading

Stock option trading presents the opportunity to potentially make a fortune trading options than almost any other form of online trading in todays market. The level of reduced risk combined with above average leverage allows a skilled option trader the chance to make sizable gains but an aspiring option trader must have a solid understanding about what creates a reliable option trading method to insure long term success at option trading. There are five fundamental steps that any option trader must implement when creating a superior stock option system.

To begin with you must realize the affects of time on the premium of the option you are choosing to trade. There are two parts you must factor when considering time into the stock option trading process. The first part that has to be considered is the time left on an option till expiration. Since stock options have a defined time period of anywhere from 30 days up to three years in some cases then you must be sure to select the proper stock option with enough time on it in order to profit. You must be sure that you purchase the correct option containing enough time on it to insure that time decay doesnt erode your investment away before your position has enough time to be profitable.

This brings us to the second part of the option selection process of trading options successfully is factoring time into your trading system. Trading a particular stock option and knowing the key factors of your option trading system or setup by knowing the average time period of a trade once it has been signaled and entered. For example, if your average holding time for an option trade is five days then you dont want to buy an option with four months of time premium left on it because you would be paying more for the extra time with the options purchase price. Nor would you buy an option with less than 30 days till expiration as time decay would eat away the value of option so rapidly that even if the stock options underlying stock moved favorably in your direction the time decay would be so great you would be too late to capture a gain in the option itself.

The third step to successful stock option trading is comprehending the relationship of volatility between the market, the underlying instrument that the option is based on, and the effect is has on the cost of the option itself. When the stock market as a whole as an index goes thru periods of low volatility or experiences low trading volume then the stocks that make up the market tend to follow general market and also begin to follow suit with periods of low volatility which cause cause the value of stock options to become cheap. However if the general markets volatility begins to spike it causes individual stock option premiums to increase in value as long as the market moves in the traders favor.

The fourth key in successful stock option trading is having a trading method that takes factor these key steps into giving clear entry signals, clear exit signals, a defined system of trade management, and a profit factor greater than your average loss over a series of trades. Understanding all steps of various trade setups is meaningless if you dont have a trading system that guides you through each step of the trade management process. A solid trading stock option system guides you by the hand and details each step while guiding you towards being a consistent winning trader in the markets and being profitable in the end.

The fifth and final step to trading stock options successfully is trading psychology. Traders and there mental makeup are usually complex so it is very important that stock option traders have a sound stock option trading system or method that factors this into their overall approach to trading the markets as well as the discipline to follow their trading methods. You can give two traders the same exact profitable trading system but its very likely that they will experience very different results. The reason for this is usually is because the one that has the ability to remain as detached from his losing trades as well as his winning trades while maintaining the discipline to follow the systems rules no matter the individual trading result will come thru as the most profitable trader in the end which shows us that it comes down to a superior mental process towards trading the markets.

Using these five steps as a foundation to create your own stock option trading system can help you avoid the mistakes of many other stock and option traders. By understanding time decay, factoring an options time into your trading method, how volatility impacts a stock options intrinsic value, what details a winning stock option trading system, and your own trading psychology you now have a the key steps to build your trading career on.
