Abstract

Embodiments of the invention relate to a display panel manufacturing method, a display panel and a display device, and relate to the technical field of display. The main technical scheme is a substrate, wherein the substrate comprises a first surface and a second surface opposite to the first surface. The method comprises the steps of: depositing an array layer on the first surface; depositing a chip on film layer; and setting a connection line on the side surface of the substrate, and respectively connecting two ends of the connection line with the array layer and the chip on film layer. Thearray layer is arranged on the first surface of the substrate and the chip on film layer is arranged on the second surface of the substrate, the second surface is a surface, opposite to the first surface, on the substrate, and the connection line, electrically connected with the array layer and the chip on film layer, is arranged on the side surface of the substrate, so that borderless design of the display panel is realized.

Description

technical field

[0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method for fabricating a display panel, a display panel, and a display device. Background technique

[0002] The display panel mainly includes: an array layer (TFT: Thin Film Transistor) and a chip on film layer (COF: Chip On Film), and the array layer has a display area for displaying. Wherein, the array layer is electrically connected to the driving chip of the chip-on film layer, and the chip-on film layer transmits the signal of the driving chip to the array layer, so that the display area can be displayed.

[0003] Nowadays, consumers pursue simplicity in the appearance of display panels. However, due to the composition of the display panel structure, as well as its overall strength requirements, reliability requirements, optical architecture and other factors, the display panel needs a frame to cover the flip chip on the substrate. thin film l...
