Osaka — Sharp Corp. has developed technology to make images more vivid on organic electroluminescent display panels for smartphones and other electronics products, company sources said Friday.
Sharper: A prototype of a new organic electroluminescent display developed by Sharp Corp. is shown Friday in Shinjuku Ward, Tokyo.
The technology involves use of an indium-gallium-zinc oxide semiconductor, a new material Sharp already employs to increase the picture definition on its liquid crystal panels.
The Osaka-based electronics firm has succeeded in applying the material to OEL panels and making their images crisper, according to the sources.
By using OEL, makers can make display panels thinner and more energy efficient than the current LCD panels widely used for smartphones and flat-panel TVs. The OEL technology centers on an organic electronic material that illuminates on voltage variations. The LCD display requires a light source in the back of a screen, while in the OEL panel, organic materials sandwiched by glass sheets themselves illuminate, allowing a thinner, brighter screen.
