Abstract

The invention provides an organic light-emitting display panel, a preparation method and a display device thereof, which relate to the field of display technology and are used for avoiding the problem of poor display effect caused by current crosstalk. Wherein, the organic light-emitting display panel includes: an anode and a cathode arranged oppositely, and an organic functional layer arranged between the anode and the cathode; wherein, the organic functional layer includes at least one microcavity adjustment layer, the The microcavity adjustment layer is a hole injection layer added with a P-type dopant or an electron injection transport layer added with an N-type dopant; the microcavity adjustment layer includes at least three microcavity adjustment units of different colors, and the three The microcavity adjustment units of different colors are arranged at intervals and have different thicknesses. The organic light emitting display panel is suitable for a display device.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel, a preparation method and a display device thereof. 【Background technique】 [0002] Organic Light-Emitting Diodes (Organic Light-Emitting Diode, OLED) are widely used in display devices due to their characteristics such as self-illumination, wide viewing angle, and short response time. [0003] Organic light-emitting display devices on the market are divided into two types: normal positive OLEDs and inverted OLEDs. In positive OLEDs, the reflective anode is in contact with the substrate. On the contrary, in inverted OLEDs, the reflective anode is in contact with the substrate. In the positive OLED, during the migration process of hole carriers, since the hole injection layer is shared between the light-emitting layers of different colors, the hole carriers will migrate laterally in this layer, thereby forming current crosstalk, resulting...
