Digitally programmable organic light-emitting tetrodes

Limited to the structure of traditional light-emitting devices, electronic devices that can directly convert machine language into human visual information without introducing any back-end circuit are still not easy to achieve. Based on a specially designed three-phase co-planar electrode structure, a new type of three-phase alternating current driven organic light-emitting device with the integration of emission and control functions, full-color tunability and simple device structure is demonstrated in this study. We integrate the light-emitting function of color-tunable light-emitting devices and the switching of three triodes in a single three phase organic light-emitting device. The state control of luminous color and luminance intensity merely requires the introduction of a kind of machine language, that is an easy-to-program 6-bit binary number coded digital signals. The color adjustable area covers 66% of the color triangle of the National Television System Committee. Such simple and easy-to-integrate light-emitting system has great potential applications in the next-generation man-machine interface.
