Abstract

The invention provides an OLED (organic light-emitting diode) device and a manufacturing method therefor, and a display apparatus. A guided-mode resonance optical filter is formed by the OLED device between a positive electrode and an organic material layer of each sub pixel unit separately; each guided-mode resonance optical filter comprises a lower electrode, a raster layer, a PDLC layer and an upper electrode; and the refractive index of the PDLC layer is controlled by controlling the voltages of the lower electrode and the lower electrode. Therefore, the raster layer is matched with the PDLC layer to form regions with different refractive indexes, so that the guided-mode resonance optical filters can realize adjustable filtration for external light only through the optical waves having wavelengths corresponding to each sub pixel unit; even if under strong light, an OLED display screen can display clear images, and the luminance of the product is not affected.

Description

technical field [0001] The present invention relates to the field of organic electroluminescence devices, in particular to an OLED device, a manufacturing method thereof, and a display device. Background technique [0002] Compared with liquid crystal display devices, organic electroluminescent devices (Organic Light-Emitting Diode, referred to as OLED) have the advantages of high luminous efficiency, low driving voltage, fast response speed, rich colors, ultra-thin and portable, and large viewing angle. It meets people's requirements for the development of modern display technology and has become the focus of attention in the field of flat panel display. [0003] According to the light emitting method, OLEDs are divided into bottom emission OLED (Bottom Organic Light-emitting Device, referred to as BEOLED) and top emission OLED (TOP Organic Light-emitting Device, referred to as TEOLED). The bottom emission OLED structure is to fabricate the OLED on a glass substrate covere...
