Abstract

The invention discloses an OLED structure optimization design method and device and belongs to OLED field. The method includes the following steps: step 1, determining the working wavelength lambda ofOLED, the optical constant of each layer material of OLED, the initial design thickness value of each layer material of OLED and the azimuth of the main axis of anisotropic material in OLED, theta and psi; step 2, establishing the multi-layer stack optical model of OLED based on the parameters identified in step 1 and adjusting the thickness of cathode, cathode finish layer, luminous layer, holetransport layer, hole injection layer, anode and the layer to be optimized in the substrate. The simulation test is conducted to obtain the external coupling efficiency of OLED at different structurethicknesses and determine the maximum structural thickness of external coupling efficiency. The device is used to executive the above method. The method has the advantages of simple principle and easy-to-operate and can realize the simulation optimization calculation of OLED structure dimension.

Description

technical field [0001] The invention belongs to the field of organic light-emitting diodes (OLEDs), and more specifically relates to an OLED structure size optimization design method and equipment, which are suitable for optimizing the design of the OLED structure size to improve its outcoupling efficiency. Background technique [0002] Since the 1960s when Pope and his collaborators performed voltage experiments on single crystal anthracene and discovered the phenomenon of blue photoluminescence (Journal of Chemical Physics, 1963, 38(8): 2042-2043), scientists have gradually begun to pay attention to organic electroluminescence. Research on luminescent materials and devices. Organic electroluminescence refers to the phenomenon that organic materials emit light under the excitation of electric current or electric field, and devices made according to this principle are called organic light emitting diodes (Organic light emitting diode, OLED). [0003] OLED refers to a light-...
