Problems solved by technology

The conventional F-P optical microcavity structure requires two reflective mirrors, and generally adopts a metal-metal structure. Therefore, the total optical path of the microcavity of the F-P optical microcavity structure is limited by the thickness and refractive index of the organic film layer in the OLED display panel. The optical path is short, and it is difficult for industry insiders to increase the total optical path of the microcavity by adjusting the organic film layer in the OLED display panel

Abstract

The invention discloses an OLED display panel, comprising: a substrate; a photochromic layer formed on one side of the substrate, including a photochromic material that changes from transparent to opaque under light excitation; a transparent anode formed on the The other side of the substrate; a light-emitting layer formed on the side of the transparent anode away from the substrate, the light emitted by the light-emitting layer includes wavelengths used to excite the photochromic material; and a semi-transparent cathode formed on the The side of the luminescent layer away from the transparent anode. The OLED display panel of the present invention has a longer total light path of the microcavity. The invention also discloses a preparation method of the OLED display panel.

Description

technical field [0001] The invention relates to the technical field of OLED display panels, in particular to an OLED display panel and a method for preparing the OLED display panel. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel is a new type of display technology developed in the middle of the 20th century. With many advantages such as wide temperature range, low power consumption, low cost, strong shock resistance and flexible display, it will become the main force of the next generation of flat panel display. Its superior performance and huge market potential have attracted many manufacturers and scientific research institutions all over the world to invest in the production and research and development of OLED display panels. [0003] However, due to vibration braiding and inhomogeneous broadening effects, whether it is an organic small molecule or a polymer luminescent material, its spectral half-width is o...
