Abstract

The invention discloses an organic light emitting diode (OLED) display panel, a preparation method thereof and a display device. The organic light emitting diode display panel comprises a white organic light-emitting diode and a metal color filter of a period nanostructure. By arranging a layer of the metal color filter of the period nanostructure to be integrated with a backlight source of the white organic light-emitting diode, a color OLED display structure can be achieved. Compared with the conventional OLED color display structure, the organic light emitting diode display panel provided by an embodiment of the invention only uses one manufacturing process to form the metal color filter. Compared with that a RGB color film layer by more than once evaporation technology in the prior art, the invention can reduce the mask number, simplify the manufacturing technology of the OLED display panel and reduce the production cost. In addition, the metal color filter of the period nanostructure is used for facilitating development of high-resolution products.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a preparation method thereof and a display device. Background technique [0002] With the advancement of display technology, organic electroluminescent display (OrganicLightEmittingDiode, OLED) is one of the hotspots in the field of flat panel display research today, and more and more active matrix organic light emitting diode (ActiveMatrixOrganicLightEmittingDiode, AMOLED) display panels have entered the market, relatively Compared with the traditional thin film transistor liquid crystal display panel (ThinFilmTransistorLiquidCrystalDisplay, TFTLCD), AMOLED has faster response speed, higher contrast ratio and wider viewing angle. [0003] The structure of the traditional top-emitting OLED display panel is as follows: figure 1 As shown, it mainly includes: flexible substrate 101, switching transistor array 102, RGB color filter laye...
