Monitors of the future

First flat screen technology was Liquid Crystal Display technology (LCD), then plasma, then Surface-conduction Electron-emitter (SED) and now Organic Light Emitting Diodes (OLED).

Kodak 1987 discovered electronic devices produced by placing a series of organic thin films between two electrodes - OLED.

" In 1987, they reported OLED materials that became the foundation for OLED displays produced today. The first color “discovered” in this early OLED research was green. Kodak has since improved the purity and brightness of color.
Organic light emitting diode (OLED) technology uses substances that emit red, green, blue or white light. Without any other source of illumination, OLED materials present bright, clear video and images that are easy to see at almost any angle."

Diodes themselves emit light, so there is no need for backlight. OLED TV are much thinner than LCDs and plasma TVs. They react faster to changes in signal than do plasma or LCDs. That makes them much better for full-motion video. Because no backlight is needed that means lower power consumption and one less component. They use a flexible substrate, they are lighter in weight and they are more durable. Also they can operate in a much greater temperature range what makes them ideal for hostile environments.
