An OLED TV screen uses a new display technology called OLED (Organic Light Emitting Diodes). OLED televisions are brighter, more efficient, thinner and feature better refresh rates and contrast than either LCD or Plasma.
A little bit about the technology
OLEDs are made by placing thin films of organic (carbon based) materials between two conductors. When electrical current is applied, a bright light is emitted. The OLED materials emit light and do not require a backlight (unlike LCDs). Each pixel is a small light-emitting diode, in fact. OLED TV panels offers several advantages over LCDs:
- Faster refresh rate, better contrast and better color reproduction
- Thickness: the LG’s EL9500 for example is just 1.7mm thick. We’ve seen prototypes of OLED televisions that are merely 0.3mm thick!
- Better viewing angle – almost 180 degrees
- Greener: OLEDs draw less power, and contain no bad metals
- OLED panels can potentially be made flexible and/or transparent…
LG’s 55″ OLED TV
In December 2011 LG officially announced their first real OLED TV, the 55″ 55EM9700. In January 2013 LG announced that the TV is now on offer in Korea (for the small price of 11 million Won, or about $10,000). This is a Full-HD panel that features 100,000,000:1 contrast ratio and fast response time (1,000 times faster than LCD according to LG). The panel is only 4mm thick, and weighs just 3.5Kg.
LG’s TV is based on LG Display’s Oxide-TFT white-OLED with color filters (WOLED, or WRGB, more on this below) OLED panel. LG are quite excited of this new TV – they call it calling it the “Ultimate Display” and they say that this is the “most transformational moment” in the TV industry since the introduction of the color TV 60 years ago.
