ERA OF OLED

 OLED stands for organic light emitting diode. It is a flat light emitting technology made by placing a series of organic thin films between two conductors. When electrical current is applied , a bright light is emitted . OLED display offer improved image quality - better contrast , higher brightness , fuller viewing angle , a wider colour range and much faster refresh rates.

About OLED

• Organic light emitting diode is a newer display technology for mobiles and monitors . It consists of  an organic layer sandwiched between two conducting sheets ( an anode and a cathode) with a glass plate at the top and bottom.
• The carbon based organic material emits electro-luminescent light when electricity is applied across the two conducting sheets.
• The panel is much thinner as it does not require backlight filters. OLEDs are superior in their colour reproduction, fast response times , higher brightness  and extremely light weight designs.

Features

• OLESDs are made of organic materials.
• The pixel of an OLED is self illuminating.
• OLEDs are expensive though OLED prices are dropping significantly .
• OLED feature a wider viewing angle than LED.
• With OLED panels the colours do not get washed out when viewers watch from different angles.
• OLED technology offers the ability to develop lighter and thinner display.
• OLED are more energy efficient.

Uses 

• Lighting applications ; OLED lighting has the illumination of higher quality , varied panel shapes , and better - diffused light sources .
• Mobile phones ; In mobile phones AMOLED technology is used in screens which has better colour contrast.
• Television sets 
• Fashion industry ; The automotive sector, production of cameras and video games.

OLED has come a long way and is expected to be mainstream display technology in the future.

How ever research is still required to address some drawbacks of  the technology.
