OLED TV Display Lighting Infos-News and resources

Eiji Shikoh, an assistant professor at the Japan Advanced Institute of Science and Technology, developed an OLED device that emits circularly polarized light in the visible light range.

It is a basic technology to enable 3D representation on OLED and electronic paper displays. To produce the circularly polarized light in the visible light range, the spin state during the light emission process is controlled by injecting a spin-polarized carrier from the ferromagnetic negative electrode into the emission layer.

The Technology Research Association for Advanced Display Materials (TRADIM) made a TFT LCD panel with a roll-to-roll method using a TFT array and a color filter formed on film substrates.

The panel was made from a 3.5-inch amorphous Si-TFT and a color filter formed on 300 (W) x 50m (L) film substrates.
This technique enabled to produce all the LCD panel components other than oriented film and liquid crystal material by the roll-to-roll method. The LCD panel announced this time used such film substrates and was assembled by the roll-to-roll method.

The Japanese government is backing Sony, Toshiba, Sharp, Matsushita Electric and some other companies in joint research of OLED TV Panels.
