Abstract

The invention relates to the technical field of display equipment, and provides an OLED display panel and a manufacturing method thereof. The OLED display panel comprises a display area and a binding area, wherein a substrate module and an OLED module are sequentially stacked on the display area, and the binding area is located on the periphery of the display area. The substrate module comprises at least one group of organic film layers and inorganic film layers which are alternately stacked; an NFC coil which is arranged on an inorganic film layer, wherein the NFC coil corresponds to a pixel matrix pattern of the OLED module and is wound into a square spiral structure, and the lead end of the NFC coil and the lead end of the pixel driving circuit are wired from the display area to the binding area; and a shielding layer which is arranged on one side of the NFC coil, wherein the NFC coil and the OLED module are shielded by the shielding layer. The OLED display panel has a display function and an electromagnetic induction function, meanwhile, the thickness of the module is reduced, manufacturing is easy, the structure is stable, the display function and the electromagnetic induction function do not interfere with each other, and the overall performance of the OLED display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Electronic devices, especially mobile phones and wearable products, usually have additional functions such as NFC (Near Field Communication, near field communication), fingerprint recognition, health monitoring, etc., which bring convenience to people's lives. Users can realize various functions through electronic devices. Features. Among them, NFC technology can realize short-distance point-to-point data transmission. In recent years, with the popularization of near-field communication technologies such as mobile payment, NFC technology has become more and more widely used in portable electronic devices. [0003] However, a traditional NFC antenna occupies a relatively large space inside the electronic device. refer to figure 1 The structure of the NFC antenna installed ins...
