Abstract

The invention provides a making method of an OLED panel and an OLED panel, wherein the making method of the OLED panel is characterized by making an anode connected with a source cathode of a TFT anda lapping electrode connected with an auxiliary electrode on a TFT substrate; making a plurality of metal salients with cusps on the surfaces in the lapping electrode; after successively forming an electrical transmission layer, an electrical injection layer and a cathode with whole surfaces in the subsequent making process, the positions of the electrical transmission layer and the electrical injection layer corresponding to the cusps of the metal salients are provided with slim film thicknesses; after further applying voltage to the auxiliary electrode and the lapping electrode, the positions of the electrical transmission layer and the electrical injection layer corresponding to the cusps of the metal salients are burnt by the cusps of the metal salients because of big impedance; thereby the cathode is connected with the auxiliary electrode, signals are input by the OLED panel to the cathode via the auxiliary electrode when displaying, and the problem is effectively improved that the OLED panel displays unevenly because of an IR pressure drop of the cathode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an OLED panel and the OLED panel. Background technique [0002] Organic Light Emitting Display (OLED) has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and With many advantages such as large-area full-color display, it is recognized by the industry as a display device with the most potential for development. [0003] According to the driving method, OLED can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor (TFT) matrix addressing. kind. Among them, AMOLED has pixels arranged in an array, belongs to the active display type, has high luminous efficiency, an...
