Abstract

The application discloses an OLED display panel, a manufacturing method thereof, and an OLED display. The manufacturing method of the OLED display panel includes: providing a base substrate; forming an anode electrode and a pixel definition layer on the base substrate, and forming the first groove, the second groove and the third groove arranged in an array around the pixel definition layer groove, the pixel definition layer includes a first dam, a second dam and a third dam, the heights of the first dam and the second dam are greater than the height of the third dam, and the first dam is located between the first dam and the second dam Between, the second dam is located between the first groove and the third groove, and the third dam is located between the second groove and the third groove; the organic light-emitting layer is respectively formed in the three grooves by inkjet printing and sequentially forming an electron transport layer and a cathode electrode covering the organic light-emitting layer and the pixel definition layer. Based on this, the present application can prevent ink mixing when inkjet printing is used to prepare the organic light-emitting layer, which is beneficial to improve poor light emission.

Description

technical field [0001] The present application relates to the field of display, in particular to an OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel, a manufacturing method thereof, and an OLED display. Background technique [0002] The inkjet printing process is an important process for preparing OLED display panels. However, due to the different luminescent materials and film thicknesses required for each color of the OLED device and the particularity of the inkjet printing process, the phenomenon of mixing different luminescent materials and inks often occurs. As a result, the OLED display panel suffers from problems such as pixel luminous color shift and color mixing. Contents of the invention [0003] In view of this, the present application provides an OLED display panel, a manufacturing method thereof, and an OLED display to solve the problem of poor luminescence caused by mixing inks of different colors in adjacent pixel regions when ...
