Novel In-organic Electroluminescence Panel Using Field Building-In Technique
Inorganic Electroluminescence (IEL) is a display technology originally developed in 1938. IEL devices consist of many parts: substrate, bottom/upper electrode, dielectric, and phosphor. The primary IEL mechanism is the interaction of a high electrical field and the energy transfer of electron ionization. IEL technique offer many advantages, such as self-luminescence, wide viewing angle, wide operation temperature range, low power consumption, flexibility, and ease of handling. As a result, IEL is well-suited to advanced products such as electronic paper, commercial billboards, and next generation displays. However, low brightness is the major disadvantage of IEL devices. This study proposes and develops a practical new method of increasing the brightness of IEL. A novel IEL device can be achieved by coating with IEL structure with a film with a Field Build-In effect, called J-film, that can be produced by corona charge method. Experimental results show that the Field Build-in effect can actually increase the IEL brightness from 321nits to 404nits at the same power consumption.
