Abstract

The invention provides an OLED display panel and a manufacturing method thereof. The OLED display panel comprises a TFT assembly, an auxiliary electrode, an anode, a lap joint electrode, a metal layer, an organic matter layer, an organic light-emitting layer and a cathode. The lap joint electrode is connected with the auxiliary electrode, and the organic light-emitting layer and the cathode are connected with the auxiliary electrode; and the metal layer and the organic matter layer have undercut structures.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Display panels, such as Organic Light-Emitting Diode (OLED for short), have attracted great attention from academia and industry because of their great development potential in the direction of solid-state lighting and flat panel display. OLED has many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide temperature range, flexible display and large-area full-color display, etc., and is recognized by the industry. It is the display device with the most development potential. [0003] Large-sized OLED panels will produce different IR voltage drops (IR Drop) at different positions due to the large resistance of the cathode during operation, resulting in uneven brightness of the OL...
