A Sony parece ser a principal interessada em vencer a guerra OLED, com o
lançamento mundial da primeira Televisão OLED, a SonyDrive XEL-1!
A tecnologia OLED (Organic Light Emitting Diode), além de não necessitar de
blacklight, detem taxas de contraste «estupidamente» melhores que qualquer
TV ou LCD, com valores a rondar os 1,000,000:1.
A Sony introduz a sua primeira televisão, com 11 polegadas e uma resolução
de 960 x 540 pixe, sintonizador de TV, 2 speakers de 1Watt, e ainda portas
USB e Ethernet.
A Sony XEL-1 chega a 1 de Dezembro do corrente ano com um preço a rondar os 1740 dólares.
imagine having a high-definition tv that is 80 inches wide and less than a
quarter-inch thick, consumes less power than most tvs on the market
today and can be rolled up when you're not using it. What if you could have
a "heads up" display in your car? How about a display monitor built into your
clothing? These devices may be possible in the near future with the help of a
technology called organic light-emitting diodes (oleds).
oled components
like an led, an oled is a solid-state semiconductor device that is 100 to
500 nanometers thick or about 200 times smaller than a human hair. Oleds
can have either two layers or three layers of organic material; in the latter
design, the third layer helps transport electrons from the cathode to the
emissive layer. In this article, we'll be focusing on the two-layer design.
An oled consists of the following parts:
- substrate (clear plastic, glass, foil) - the substrate supports the oled.
- anode (transparent) - the anode removes electrons (adds electron "holes") when a current flows through the device.
- organic layers - these layers are made of organic molecules or polymers.
- o conducting layer - this layer is made of organic plastic molecules
that transport "holes" from the anode. One conducting polymer used in oleds is polyaniline.
- o emissive layer - this layer is made of organic plastic molecules (different ones from the conducting layer) that transport electrons from the~~ cathode; this is where light is made. One polymer used in the emissive layer is polyfluorene.
* cathode (may or may not be transparent depending on the type of ~~oled) - the cathode injects electrons when a current flows through the device.
