Abstract

The invention provides an OLED (Organic Light-Emitting Diode) device and a manufacturing method therefor, and a display apparatus. In the OLED device, an optical filter is formed between a positive electrode and an organic material layer of each sub pixel unit separately; each optical filter comprises an optical filter lower electrode, a first reflecting layer, a piezoelectric material layer, a second reflecting layer and an optical filter upper electrode that are laminated in sequence; and the dielectric refractive index of the piezoelectric material layer is controlled by controlling the voltages of the optical filter lower electrode and the optical filter upper electrode. Therefore, the optical filters can realize adjustable filtration for external light only through the optical waves having wavelengths corresponding to the sub pixel units; and in addition, 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 invention relates to the field of organic electroluminescent 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 Light-Emitting Diode (OLED) has the advantages of high luminous efficiency, low driving voltage, fast response speed, rich colors, ultra-thin and portable, and large viewing angle. It has met 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 way of light emission, OLED is 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-emitting OLED structure is to make the OLED on a glass substrate covered with transparent indium tin oxide (Indium Tin Oxides, referred t...
