How to make your own OLED display in several not-so-easy steps

Organic light-emitting diode ( OLED) display technology has long been waiting in the wings as a replacement for screens in everything from smartphones to HDTVs, but its development hasn’t happened as quickly as most people thought.

Kodak produced a digital camera with an OLED screen back in 2003, but problems in scaling up this low-power, high vibrancy display technology mean that mainstream production is still limited to small sizes — the Google Nexus One has a 3.7” OLED screen that doesn’t adversely affect the price, but the 11” Sony XEL-1 OLED TV will set you back almost £3,000.

All of which is a roundabout way of saying that OLED manufacturing is hard — and you can see just what the process consists of, thanks to the University of Wisconsin.

Its Preparation of an Organic Light Emitting Diode page explains how you can make your own OLED pixel using nothing more than water, polyvinyl alcohol, [Ru(bpy)3](BF4)2, GaIn Eutectic, some conductive glass, a cooling fan, some sticky tape, aluminium foil, duct tape, a hole punch, a cotton swab and a hair dryer. So, what are you waiting for?
