OLEDs are organic LEDs. You must have heard this word for food or clothes. In the lighting industry, it means the light panels that make use of organic compounds to emit light. OLEDs are improved version LEDs and are more human and environmentally friendly. LEDs still use inorganic compounds of mercury and phosphorus to emit light under electricity which creates pollution in our environment. There are several layers in it where light is generated, substrates and encapsulated. OLEDs are flexible, thinner, foldable & much more efficient thus have created a revolution in LED technology. The form of lights and panels can be easily moulded with the advancement of this technology.
Components of OLED:
1. Substrate: It is the base material of an OLED which is made of thin translucent glass.
2. Anode: The work of anode is to emit electrons when an electric current is provided to terminals.
3. Organic layer: This layer has conductive polymers made up of carbon or hydrogen molecules.
4. Conductive layer: This layer helps in movement of holes from anode.
5. Emissive layer: Emissive layer helps in transporting electrons from cathode.
6. Cathode: Cathode injects electrons when a potential difference is applied across terminals.
Types of OLEDs panels
- High Brightness White with different CCT
- Saturated Colour Panel
- High Brightness curved bendable panel
- General Lighting: Today the fancy lights are used everywhere be it home, office or commercial shops.
- Signage Lighting: OLEDs flexibility helps in making beautiful & attractive signages.
- Effect Lighting: OLEDs can create magical lighting effects and thus are highly useful at public places like malls, restaurants, discs and pubs. They are also used in shows & events.
- Merchandising Lighting: As we already know that OLEDs can be made flexible, and transparent, and so open the way for new, exciting display applications. We have all seen the stylish curved bendable OLED panels for the display of clothes and other merchandise. With the passage of time, these panels will become more popular.
- Automotive Lighting: Currently, Lexus 2010 RX uses white OLED display. But most of the upcoming high end cars will use OLED technology. It can be used in:
- Dashboard displays: For smooth navigation & for playing audio and video files.
- Internal lighting
- External lighting : which includes tail lights, indicators etc.
- Digital rear-view internal mirrors
Benefits of OLED Technology
- Flexible & Foldable
- Cut all the harmful blue light
- Lower eye strain and fatigue
- Much thinner than normal LEDs (1.4mm to 2.1 mm)
- No Harmful chemicals like mercury & phosphorus
- POE Compatible
- No Photobiological Risk
- Easily Dimmable
- Cool to touch and No UV
- Sustainable mostly glass
- No Flicker No glare
- Naturally diffused & has a full spectrum
Lighting Technology has been revolutionized by LED. With the passage of time we have seen a dramatic improvement in LED Technology. Truly, it has moved beyond the basic illumination.
