Embodiment Construction

[0044] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a flexible electronic device provided by related technologies. The flexible electronic device may include: a plurality of rigid elements 01 and a plurality of flexible wires 02 arranged in an array. Each rigid element 01 includes at least one TFT. The TFTs of any two adjacent rigid elements 01 are connected by at least one flexible wiring 02. A rigid protective layer 03 is provided on the outside of each rigid element 01. The protective layer 03 can protect the TFT in the rigid element 01.

[0046] Because the part of the flexible wiring 02 wrapped by the rigid protective layer 03 is not easy to deform (that is, the tensile strain rate is small, the tensile stra...

Abstract

The invention discloses a flexible electronic device and a manufacturing method thereof, and a flexible display device, and belongs to the technical field of semiconductors. The flexible electronic device comprises a flexible substrate, wherein the flexible substrate is provided with a plurality of functional element regions arranged at intervals; each functional element region is internally provided with at least one TFT and a rigid protective layer for coating the exterior of the at least one TFT; a plurality of flexible wires are further arranged on the flexible substrate; the TFT in each functional element region is connected with the TFT in the other functional element region through at least one flexible wire, wherein the thickness of the central area of the rigid protective layer arranged in each functional element region is larger than the thickness of the edge area. The thickness of the edge region of the rigid protective layer in the flexible electronic device is small, so that the probability of breakage at the position where the flexible wire is in contact with the outer surface of the rigid protective layer is effectively lowered.

Description

Technical field [0001] The present invention relates to the field of semiconductor technology, in particular to a flexible electronic device, a manufacturing method thereof, and a flexible display device. Background technique [0002] Flexible electronic devices have unique ductility, and the manufacturing cost of the flexible electronic devices is low, and it has broad application prospects in the fields of information, energy, medical treatment and national defense. [0003] The flexible electronic device may include: a plurality of rigid elements arranged in an array and a plurality of flexible traces, each rigid element includes at least one thin film transistor (English: Thin-film transistor; abbreviation: TFT), and any two adjacent rigid elements The TFTs in the device are connected by at least one flexible trace. Since the flexible electronic device is frequently bent during use, in order to avoid damaging the TFT in the rigid element, a rigid protective layer can be provid...
