Abstract

An embodiment of the invention provides an OLED display panel and a production method and testing method thereof and relates to the technical field of display. By the production method, circuit scratching during the production of the OLED display panel can be avoided. The OLED display panel comprises an array substrate and an encapsulation cover plate, wherein the array substrate comprises a display area and a peripheral wiring area; the peripheral wiring area comprises circuits arranged at the edge of the array substrate and conductive adhesive strips arranged above the circuits; the conductive adhesive strips extend along the direction of the edge close to the display area; the conductive adhesive strips are conductive in a Z direction and non-conductive on an X plane and a Y plane; the Z direction is vertical to the substrate of the array substrate. The OLED display panel is used for an OLED display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel, a preparation method and a testing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED) display is an organic thin film electroluminescent device, which has the advantages of simple preparation process, low cost, easy formation of flexible structure, and wide viewing angle. Therefore, the display technology of OLEDs has become an important display technology. [0003] The OLED display includes an array substrate and a package substrate, and the array substrate includes a thin film transistor (Thin Film Transistor, TFT for short) and an OLED light-emitting device composed of an anode, an organic material functional layer and a cathode. The organic material functional layer needs to be formed by evaporation process. [0004] In the evaporation process, a mask plate is needed, and the mask plate is easy to scratch the circuit on...
