Latest Patents
Yi-Jiun Chen's latest patents include innovative designs for electroluminescent devices and display pixel structures. One of his notable inventions is a highly effective and scalable OLED display pixel structure. This design embeds the OLED within a three-dimensional reflective concave structure, which is selectively filled with a high-index filler material. This configuration maximizes the internal generation of photons, redirecting confined light for improved out-coupling. The result is a high light extraction efficiency approaching 80%, along with excellent viewing characteristics. This scalable and wavelength-insensitive scheme can be applied to all red, green, and blue pixel OLEDs in high-resolution full-color displays.
Another significant patent involves an electroluminescent device that features a nanostructured composite electrode. This device comprises functional layers and a top electrode, with the nanostructured composite electrode consisting of a first layer with a nanostructure and a second layer. Both layers are transparent and conducting, with specific refractive indexes that enhance the device's performance. The design ensures that the feature pits and intervals of the nanostructure are optimized for the emitted light, further improving the device's efficiency.
