What are OLED Televisions?
Monday, March 8th, 2010Going green, or being sustainable seem to be trendy names these days as the society has done everything to change products so that they’ll have a more environment friendly appeal. Today there are electric cars, solar panel housing, and recycling centers for all types of materials (cardboard, paper, aluminum, and electronics) and with all this green hysteria it appears that technology has put another strong green foot forward with the development of OLED or electronic light emitting diode television screens. No the OLED isn’t a new surging brand market name, but a type of television screen that in a few years will strongly compete with the common LCD, liquid crystal displays and plasma television screens.
So what is OLED and how does it work?
Well, OLED works with a series of electroluminescent layers composed of a film of organic compounds which are placed between two electrical conductors. Electrical current is applied to the conductors and a bright light is emitted from the film.
What are the advantages of an OLED television compared to an LCD television?
The first advantage of an OLED television is that unlike LCD televisions it does not have a backlight. This means that an OLED television can have deeper black levels and be thinner and much lighter. Some screens measure to be 3mm thick which is a futuristic contrast to the clunky big LCD screen televisions. OLED televisions also have a faster refresh rate, better contrast and better color reproduction. OLEDs have higher natural contrast ratios because they use cold cathode fluorescent lamps. The greater artificial contrast ratio is measured in primarily dark conditioned settings. Another advantage of OLED televisions is the viewing angle. An OLED has an almost 190 degree viewing angle as the color pixels don’t seem to shift with the viewers position to the screen.
One of the biggest advantages of an OLED television is the decrease in power consumption. The OLED is a green friendly innovation which consumes no light and therefore doesn’t need to power a backlight. They also contain no bad metals in order to be produced. They’re organic illuminating machines, which continue to challenge the future of television screen technology. With OLED it might not be a surprise to see flexible and transparent screens which can be rolled up to make a circle and appear almost invisible when not in use. What appears to be a bare wall can transform into a mega big screen entertainment center with the click of a switch.
OLED screens are already being used for commercial products such as cell phone screens, digital audio players, car radios and digital cameras but it is just a matter of time before this green technology explodes on the scene for the general television consumer. What a world it will be when OLED television screens are used for anything from a family television set, to a portable visual screen for a tee shirt. With OLED television technology going green will become more and more of an increasing trend due to the visual capabilities accompanied by innovative environmental practice.
