About Inorganic EL

Inorganic EL refers to a device that uses zinc sulfide or other inorganic material as the phosphor material and that emits light by utilizing the electro-luminescence phenomenon.
Inorganic EL is used in display devices. Another type of display device that uses EL in a similar way is organic EL, which is in widespread use. Organic EL is vastly different from inorganic EL in that the former uses an organic compound as the phosphor material while the latter uses an inorganic compound.
It has been considered difficult to realize color display with inorganic EL when compared to organic EL, and an appropriate blue material needed to enable both high luminance and long service life has not been found for a long time. For these reasons, the development of inorganic EL color display devices has not been advanced as much as that of organic EL counterparts. Now, as the development is moving forward with appropriate materials in hand, it is expected to be possible to realize inorganic EL display devices that are superior to organic EL counterparts in terms of the screen size and service life.

■ Surface-emitting display that allows the same amount of light to be received from across the light-emitting face
■ Light that is easy on the human eyes (only visible light rays present)
■ Flexible design is possible; the color can be selected freely.
■ Low power consumption design
■ Resistant to shock and vibration
■ No heat generation
■ Emits light even at extremely low temperatures.
■ Thin and lightweight
■ Specially shaped EL sheets can be produced in small lots.
■ 3D-EL shaping is also possible.
■ Made in Japan
