Embodiment Construction

[0053] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0054] The present invention is aimed at the existing OLED display panel, because the distance between the light-emitting units is very small, and in the case of low current, the charge released by one of the adjacent two anodes passes through the first common The layer can enter the light-emitting unit corresponding to the other of the two adjacent anodes, so that the a...

Abstract

The present invention provides an OLED display panel and a manufacturing method thereof. The display panel includes: a thin film transistor layer, an anode layer, a pixel definition layer, a first common layer, a light emitting layer, a second common layer, a cathode layer and an isolation layer; The blocking layer is disposed on the pixel definition layer between any two adjacent anodes, and the blocking layer is used to block the charge released by one of the two adjacent anodes from entering the cathode layer A region corresponding to the other of the two adjacent anodes. Beneficial effects: the present invention blocks the charges released by one of the two adjacent anodes from entering into the two adjacent anodes through the first common layer by setting a blocking layer. The light-emitting unit corresponding to the other eliminates the phenomenon of light leakage and improves the display effect of the OLED display panel.

Description

technical field [0001] The invention relates to the technical field of flat panel display manufacturing, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) display has many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and has gradually become the successor. The third generation display technology after liquid crystal display. Compared with LCD (Liquid crystal displays, liquid crystal display), OLED has the advantages of saving power, being thinner, and having a wider viewing angle, which is incomparable to LCD. At present, people have higher and higher requirements for the fineness of the display, that is, the resolution, but the production of high-quality, high-resolution OLED displays still faces many challenges. [0003] The core comp...
