What is the difference between LCD and OLED?
LCD is a display system that uses Liquid crystal liquid to create polarised dots on a sheet of glass in front of a polarised sheet. When a current is passed through the LCD it…s molecules line up and become polarised. When this is at 90 degrees to the polarise sheet it blocks light. A Fluorescent tube behind the sheet produces light which is blocked by the LCD when polarised. This technology uses lots of glass and is definitely NOTsuitable for a flexible display. It also uses a high current and Organic Light emitting diodes were invented when a Japanese scientist was trying to create a super light solar cell. One night he made a mistake and wired the panel up and put voltage through the organic compound he was testing. To his surprise it lit up. OLED displays use this active light generating technology. It has the advantage of being low current and high brightness. It can also be painted onto flexible surfaces to make ultra light weight flexible displays.
