Problems solved by technology

[0004] In the evaporation process, a mask plate is needed, and the mask plate is easy to scratch the circuit on the array substrate located in the peripheral wiring area and close to the edge of the array substrate during the alignment process, resulting in When the panel is performing a lighting test, there is a dark line defect
In addition, when packaging, if metal packaging is used, the edge of the metal film will easily scratch the circuit on the array substrate located in the peripheral wiring area and close to the edge of the array substrate during the alignment process.

Abstract

Embodiments of the present invention provide an OLED display panel and its preparation method and testing method, which relate to the field of display technology and can avoid scratches on circuits during the process of manufacturing the OLED display panel. The OLED display panel includes an array substrate and an encapsulation cover plate, the array substrate includes a display area and a peripheral wiring area; the peripheral wiring area includes a circuit arranged on the edge of the array substrate, and a conductive glue arranged above the circuit strip; the conductive glue extends along the direction of the edge of the adjacent display area; wherein, the conductive glue strip is conductive in the Z direction and non-conductive in the X and Y planes; the Z direction is perpendicular to the array substrate the substrate. For OLED display devices.

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...
