Sony, Idemitsu to Make OLEDs Together

Facebook X LinkedIn Email
TOKYO, Japan, Nov. 30 -- Idemitsu Kosan Co. Ltd. and Sony Corp. have signed an agreement to jointly develop new organic light-emitting diode (OLED) luminous materials by sharing each other's OLED-related patents. The formal contract is expected to be signed at the end of January.

OLED is a self-luminous display which emits light by running an electric current through organic luminous materials. The organic luminous layer is placed between two glass panels, so no backlight system is required, resulting in a much thinner display. OLED, with its excellent color reproduction capability and high-speed response to moving images, is considered to be the most viable next-generation flat display.

Idemitsu says it developed the world's brightest blue-light organic luminous material in 1997, based on its molecular engineering and organic synthesis technologies. Idemitsu has since continuously been developing new luminous materials for the mid-large size OLEDs and working on new technologies. Sony says it is developing various material and component technologies for the creation of a mid-large size OLED panel.

Glossary
light-emitting diode
An LED, or light emitting diode, is a semiconductor device that emits light when an electric current passes through it. LEDs are widely used in various applications due to their energy efficiency, compact size, and long operational life. The technology behind LEDs is based on the phenomenon of electroluminescence. Key characteristics and features of LEDs include: Electroluminescence: The process by which LEDs emit light is called electroluminescence. It involves the recombination of...
luminous
Pertaining to electromagnetic radiation as perceived by the eye; that is, with the contributions as wavelengths in the visible region weighted according to V(λ), which symbolizes the spectral luminous efficiency.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
