The term set-top box will become a misnomer in the near future, as most displays will be too thin to allow them to place a box on top of the page. As the prices of plasma and LCD displays have dropped and their image quality has improved, they are being seen everywhere at home.
Although they are the darling of the media and generic for displaying flat panels in the minds of many, plasma plane panels are going to have a deadly battle with other technologies for crowns.
OLED panel displays, which have been seen as computer monitors on desktops for years, and common on small flat-panel TVs, are finally growing in size and they are competing with plasmas in the 42 “- 50” size range. The image quality is similar to plasmas; However, LCDs are resistant to burn-in which can affect plasma displays.
Here comes OLED
OLED (Organic. light. OLED (already popular on MP3 players and cell phones) has amazing possibilities – slim TV, flexible display, transparent monitor, white-bulb replacement, and much more.
The LCD works after having a backlight (white light) source and then filters this source to create color. OLEDs, however, work by emitting colored light. It has several advantages. This simplifies and thus allows for the creation of thinner and cheaper displays. This means that LEDs require less power. Suppose that when you have a screen that is completely black (but turned on), the LCD will still need to emit a full white backlight. With OLEDs, there is no energy consumption at this stage! Flexible LED displays and even transparent displays are possible, but it is obviously more challenging than ordinary LCD-like displays.
Although LEDs are promoted as the display technology of the future, they are already in production and in use today. Although creating large panels is still a big challenge, smaller screens (up to 2 “) are already produced in commercial quantities today. There are many MP3 players and cellular phones that use LED displays.
LEDs actually make it possible to create screens that are flexible and/or transparent. The possibilities for such a display are almost endless. Think car windshield-embedded transparent displays, or rolling mobile TVs. The technology is still in its infancy, but companies are already showing sketches of prototypes and designs.
One area that seems most promising for OLED is white light. Many companies are hoping that LEDs will enable very efficient light sources. For today’s high energy consumption, and efficiency gain, white-light research has a lot of meaning, and OLED is seen as one of the best technologies of the future. OLEDs will also enable unimaginable design due to their slim and flexible nature.
Other technologies are also on the horizon. One of the great promises for organic light-emitting diodes is OLED. Developed by Kodak and Pioneer, this technology has been used in car stereo and cell phone displays for years. It is ready for prime time. Philips showed a 13 “unit, the Samsung a 17”, and the Seiko-Epson a 40 “prototype.
The advantages of OLED are many. It actually emits its own light, so it doesn’t need a backlight and has better contrast than a traditional three-dimensional LCD. The OLED panel display has wide viewing angles like plasma displays. Power consumption is very low, less than 1/2 from a conventional LCD display. At a depth of about 2 mm, OLEDs are much thinner than plasma or LCD.
They have a nearly 1000 times faster refresh rate than a traditional themed LCD, so they will be much better for video applications. They have fewer parts than LCD or plasma and can be made using a new inkjet printing process. It promises to keep prices low as the technology is implemented.
Basic construction Two glass plates separated by a vacuum. One plate is coated with phosphor and the other is mounted with an electron emitter. When a voltage of 16 to 18 V is emitted, electrons are emitted. These electrons are accelerated by a high voltage in a ray similar to a CRT display.
CRT display, great color, deep black layer, and visual advantage of SED region for fast speed response. These advantages, combined with the slim form factor, low cost, and small power requirements should be the real winner.
