#WhatIs : What is an OLED Display?

OLED (Organic Light Emitting Diodes) 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.
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)

OLEDs are not just thin and efficient – they can also be made flexible (even rollable) and transparent.

The future – flexible and transparent OLED displays                                                                                     OLEDs can be used to create flexible and transparent displays. This is pretty exciting as it opens up a whole world of possibilities:Curved OLED displays, placed on non-flat surfaces,Wearable OLEDs,Transparent OLEDs embedded in windows ,OLEDs in car windshields, New designs for lamps and many more we cannot even imagine today.

Where can I find OLED displays today?
OLEDs are used today in mobile phones, digital cameras, VR headsets, tablets, laptops and TVs. Samsung is the clear leader in OLED production for mobile devices, and the company uses OLEDs in all of their flagship devices – such as the Galaxy S6, the Note 5 and the very latest Tablet Pro S.

 

 

 

Other companies, including Apple, Motorola, Dell, Sony, Microsoft, LG and Lenovo are also using OLEDs in some of their mobile devices. OLEDs are used in mobile devices today because they are thin, efficient and bright. OLEDs carry a price premium over LCDs, but companies are using these displays more and more as performance increases and prices decrease. Here’s our list of products and gadgets with an OLED display.

OLED disadvantages

OLEDs have limited lifetime (like any display, really), that was quite a problem a few years ago. But there has been constant progress, and today this is almost a non-issue. Today OLEDs last long enough to be used in mobile devices and TVs.
OLEDs can also be problematic in direct sunlight, because of their emmissive nature. But companies are working to make it better, and newer AMOLEDs (such as Samsung’s Super AMOLED and Super AMOLED Plus and Nokia’s CBD displays) are quite good in that respect – some even consider them superior to LCDs.
Can OLEDs produce white lighting?
Yes, OLEDs actually make for a great light source. OLEDs offer diffuse area lighting and can be flexible, efficient, light, thin, transparent, color-tunable and more. OLEDs will probably be used in completely new lighting designs.
