OLED (organic light emitting diode) technology

B. Madhumitha, T. Priyanka

Abstract


Organic light-emitting diodes (OLEDs) have been regarded as one of the most promising technologies for future displays since Kodak's breakthrough in 1987. A variety of materials have been created and enhanced to meet the needs of this application. The structure of the materials varies from one another, as does the process that produces the electroluminescence (fluorescence versus phosphorescence). These materials, when stacked correctly, produce a device with the necessary extended lifetime and excellent efficiency. The center of a display can then be created by combining these red, green, and blue devices into matrices. One of the issues facing the industry is mounting these structures onto a display backplane. The pixel driving circuitry can be modified to work with the OLED, sometimes at the sacrifice of the display's simplicity, while keeping in mind that the manufacturing process needs to be economically feasible.
