New technology, new questions. Time to get things right!
One of the newest lighting technology is Organic LED. This new type of lighting does have several benefits and unique features. It is used already in many products and we will see OLED more and more in the coming future. Nowadays, there are two types in the market: OLED and AMOLED. What are these and what are the differences?
What is OLED and AMOLED?
OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic extremely thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and so are thinner and more efficient than LCD displays(which do require a white backlight). AMOLED is a little bit different, but the extremely thin sizes and the basic idea is the same. AMOLED stands for Active-Matrix Organic Emitting Diode.
How does OLED works?
OLED works by passing electricity through micrometer layers of organic semiconductors sandwiched between two electrodes. The electric current travels from the positive to the negative electrode through the organic film, causing the film to emit light. Using different materials in the film causes the OLED to emit light of a different color. To protect the organic layers, the OLED is completely sealed between two glass plates.
Benefits OLED:
- OLEDs offer a unique lighting aesthetic, being 2mm thin
- Light emission is even across the device and from all viewing angles
- The colour is usually an off-white and there are limited shapes available
- The operational lifetime is 5,000 to 20,000 hours depending on how they are driven
