Developing next-generation low-energy OLED displays

OLED technology: the future of next-generation displays

OLED utilizes the inherent characteristics of organic materials that emit light in the presence of electricity. OLED technology is suitable for televisions and other display panels, and offers a promising next-generation alternative to liquid crystal and plasma displays. OLED displays are very thin and boast excellent color reproduction; however their primary advantage is low power consumption. OLED is widely acclaimed as the future of low-energy displays.

Planar evaporation sources for large-scale display substrates

Organic layer deposition is a key determining process in OLED production that dictates both performance and costs.
Hitachi Zosen has developed an organic layer deposition manufacturing system featuring proprietary planar evaporation source technology that does not require movement of the substrate or evaporation source. This enables efficient organic layer deposition on very large display substrates.
The planar evaporation source technology developed by Hitachi Zosen can be used in production of large displays, which has been a key issue in adapting OLED for televisions.

Electron beam evaporation technology

Electrode layer deposition is used for the following organic layer deposition processes.

Hitachi Zosen has developed an electron beam deposition system designed to enable high-speed deposition of the OLED metal layer without compromising the properties of the under layer.
This electron beam deposition system is expected to promote the development of next-generation OLED lighting products as well as OLED displays and LED devices.

Green IT Project

Hitachi Zosen is part of a Green IT Project sponsored by the New Energy and Industrial Technology Development Organization (NEDO) on the development of next-generation OLED displays. A key aim of the Green IT Project is to significantly reduce the power consumption of display devices, thereby minimizing CO2 emissions and helping to combat global warming.
It is estimated that the average 40-inch LCD or plasma television consumes around 180 W of power. The objective of the Green IT Project is to produce a 40-inch OLED television with power consumption of just 40 W that will achieve a substantial reduction in CO2 emissions.
