Problems solved by technology
Since the protective layer 14 covering the PPA mark 13 will reduce the contact area between the conductive electrode 15 and the cathode 12, which will affect the contact between the cathode wire 11 and the cathode 12, and increase the resistance drop of the cathode voltage, so how to increase the conductive electrode 15 The contact area with the cathode 12, thereby reducing the resistance voltage drop of the cathode voltage is a problem to be solved urgently by those skilled in the art

Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] The general inventive concept of this application is: based on the backplane process, the cathode wire needs to be connected to the cathode through the conductive electrode, and the protective layer covered on the PPA mark in the PPA mark area will affect the contact between the conductive electrode and the cathode. The area of the protective layer covering the PPA mark is smaller than the area of the PPA mark area, so that the conductive electrode a...

Description
technical field [0001] The present invention relates to the field of display technology, in particular to an organic electroluminescence (English name: Organic Light Emitting Diode, English abbreviation: OLED) display panel and an organic electroluminescence display. Background technique [0002] With the development of OLED display panels in the direction of high resolution and narrow borders, OLED display panels have higher and higher requirements on the resistance drop of cathode voltage (the voltage drop caused by cathode resistance). [0003] The contact effect between the cathode wire and the cathode layer, which transmits the cathode voltage to the cathode, has a very important influence on the resistance drop of the cathode voltage. Usually, in the backplane process, the cathode wire is in contact with the conductive electrode on the same layer as the anode layer, and the conductive electrode is in contact with the cathode. When transmitting the cathode voltage to th...
