OLED HDTV
Definition
We’ve all seen them in Sci-Fi movies: newspapers being read on paper-thin TVs, mini-TVs in people’s clothing, TVs that curve around power poles. If these Sci-Fi visions are going to come true, then it will be accomplished using OLED(Organic Light Emitting Diode) technology.
OLED works by having a positive (anode) layer and a negative (cathode) layer sandwiched between a light producing organic material. When electricity is applied between the cathode and anode, a small controlled current travels through the organic material. The current causes electrons to move from the organic material. These displaced electrons are replaced by “holes” (the opposite of an electron), with light being produced in this process. What color the light is depends on the type of organic material used.
Speculated Upside
- Very thin (millimeters thick)
- Low power
- No backlighting required
- Quick response time to reduce motion blur
- Wide viewing angles
- Transparent OLED screens possible
- Foldable OLED screens possible
Speculated Downside
- Short lifespan
- Low brightness levels
- Availability – don’t expect a commercial HDTV version this decade
