The new innovative technology that we found that is taking the old technology and turning it into something new and more economical while making it a better option for customers.  This type of technology is called a field emission display (FED).  A Field emission display is a type of flat-panel display that provides a higher image quality, requires less power, and a wider field-of-view.  The field emission display is a new feature of a hybrid television technology.  The field emission display is going to be ahead of the market because the screens are cheaper to make, as they have fewer total components.  This new technology will help many businesses in different aspects.  The field emission display can help in the medical field for imaging purposes, in the television industry for entertainment purposes, and in the business organizations that use video-conferencing over the Internet. 

 

The field emission display (FED) was designed and innovated by three professors at the Cullen College of Engineering which is based at the University of Houston.  Vincent Donnelly, Demetre Economou, and Paul Ruchhoeft were the main developers who moved the television industry away from the liquid crystal display to the better-quality field emission display.  These three talented professors have been perfecting the technology for four years prior and then filed for the patent in December 2006.  They also hope that the field emission display technology can become commercially available in five to ten years and they look forward to the FED to become a feasible method for large-scale production.  The display will run at 240 frames each second, which is the fastest video display type.  The innovators hope the color quality and richness in flatter screen panels produce more light efficiently.

 

The Field Emission Display is based upon the idea of exciting an emissive phosphor material with accelerated electrons. In the field emission display there is a new television display in which electron emitters, arranged in a grid, are individually controlled by the “cold” cathodes to generate colored light.  This new hardware is closely related to the liquid crystal displays (LCD).  Field emission display has developed a thin film that allows for a display device that is smaller, lighter, and lower powered than cathode-ray tubes (CRTs).  In a cathode-ray tube an electron “gun” shoots electrons at a phosphor-covered screen which creates an image.  The larger the screen, the farther away the gun must be to reach all points on the display.  The film in the FED has a super-high brightness electron emission that will allow use of the same bright phosphor screens already used in television monitors.  The   Field emission does not rely on heating the cathode to boil off electrons.  Cathodes can therefore be packed close together with their supporting electronics without causing the entire display to overheat.  The assembly of cathodes can then be placed close enough to the glass face of the display.  The FED displays have the brightness and image quality of a CRT without any of the distortion or blurriness problem because the display uses a large array of carbon nanotubes.

 

Field emission displays are generally energy efficient since they are electrostatic devices that require no heat or energy when the television is off.  When the television operates, nearly all of the emitted electron energy is dissolute on phosphor bombardment and the creation of emit unfiltered visible light.  The FED television addresses the cost factor that keeps other technologies from mass consumption.  Also, the field emission display can have lower cost for providing both the extremely large area slim television at an affordable cost that will run directly with HDTV revolution.  Analysts predict that the field emission display market will reach over $20 billion by 2010.  The Analysts also feel that if the right technology choices are made then the field emission display will soon be a multi-billion dollar industry.  Although, there are no consumer production FED models available in the United States a few small display panels have been produced in other countries.

 

This new technology will impact business organizations and personal desires by revolutionize the television and display field.  The new technology that FED has created shows potential to ultimately change and create high levels of competition in several instances.  These instances include many television displays that already exist such as: liquid crystal display, high definition display and any television that is not upgraded to those standards.  Also, since there are television displays that have already been discovered, the engineers at Houston University knew what people wanted in a product so they built all the amenities into one.  This is why the field emission display is going to be such a big deal around the world.

 

This new field emission display is going to be very helpful in the medical imaging, meetings over the internet, and anything that a television display would be used.  The medical imaging is great for ultrasounds for expecting parents and the screen on monitors in the emergency room and in everyday doctor’s office.  Also, in business meetings where people are across the United States and people need to be face-to-face to get full understanding of the meeting.  A strong advantage that the field emission display has over other companies that are producing television displays are easy to find.  The FED will soon have a mass production of the display devices, which will set the screens ahead of everyone else.  Also, this screen display has a good mix of what customers want.  It has great non-blurry screen that makes the brightness and image quality a step ahead of the other competitors.  Overall the expansion of field emission display technology can have a major impact on how people conduct business and produce new technology.

 

In Conclusion, the field emissions display will revolutionize the television era greatly.  There are many uses for the flat panel television.  As discussed, hospitals can use them for ultrasounds.  Many people can use of them for everyday routine living.  They could put them in cars, trucks, and even military personnel can use them. People in the business world can even make use of them.  They could possibly use them for videoconferencing, which today, some businesses use the standard phone line to make conference calls.  The use of the new FED may also not be the fact that it is just useful.  People may also want them because of the convenience and energy efficiency of the new technology.  Whatever the use, the new FED technology has become the advanced portrait of what the television should be used for.
