Flexible organic LED technology
Design of OLED
Organic LED technology works almost the same as previous LED technology. Traditional LED technology used n-type and p-type semiconductors to project light. Organic LED uses organic molecules to produce electron pules. The OLED is made of six different layers . There is a protective glass or plastic layer. Which is called the seal and substrate layers. Between them there is the cathode (negative terminal). And the anode (negative terminal). Lastly, in-between of those two layers are the emissive layer (light is produced to cathode) and conductive layer (light produced to anode).
How does it work?
By supplying it with voltage to the anode and cathode. The cathode receives electrons and the anode loses electrons. This equally exchanged electrons between the anode and cathode causes negative and positive to be formed in the layers. There are positive holes and negative electrons that combine each other to emit energy (which is the light we see). A process called recombination. This happens every second when the OLED is feed with continuous electricity. The colors of the device is made by colored filters in the plastic layers of the device. If there where enough of these filters, they can have the same effect as pixels on a computer monitor. Giving hi-resolution colored pictures.
The advantages/disadvantage of OLEDs
- They are thinner then LCDs.
- They are lighter and flexible then LCDs.
- They are brighter and no back-lighting, consuming less power then LCDs.
- Are 200 times faster then LCDs, can handle fast moving pictures such as TV or computer games.
- Produce truer colors and black.
- \Lower cost in future pricing, because of their simplicity to make.
- A disadvantage of it now is their life span by usage.
- Another would be it is sensitive to water.
- And that it be challenging the cellphone for marketing.
How would this be a benefactor to the gaming industry?
It could probability run small games that where previously only available to cellphones or small gaming devices at better resolutions. Make it even more bigger then the cellphone because it is lighter and wearable. Make new interactive ways for the player to play the games with motion detection tech. And that it is more interesting to use then a cellphone. Maybe the device will create games that will center around the heath of the user with exercising or aiding outdoor sports such as paint ball. Such as the map of the paint ball grounds and kill/hits from enemies. Or transitional tag.https://www.youtube.com/watch?v=iu6lJJbJs_M
