Document Type and Number:
WIPO Patent Application WO/2021/081957
Kind Code:
A1
Abstract:
The present application relates to the technical field of display, and disclosed are a display panel, a preparation method therefor, and a display device. The display panel comprises: a rigid base substrate; a flexible insulating layer, comprising a first part and a second part, wherein the first part is disposed on the base substrate, and the second part extends beyond a side edge of the base substrate; and an integrated circuit chip and a flexible circuit board, which are separately bonded and connected to the second part of the flexible insulating layer. The bezel of the display panel may be designed to be very narrow. Specifically, the bezel may be narrower than the bezels of COF and COG. Moreover, compared to a COF packaging scheme, the display panel provided in the present application may be achieved only by using a COG bonding process and a simple flexible deposition process, and the process is simple and very practical. In addition, the display panel provided in the present application may be applied to both rigid OLEDs and LCDs, which may improve the competitiveness of rigid panels in the full-screen era.
