Problems solved by technology

[0003] During the bending process of the foldable display device, the flexible circuit board will be bent accordingly, and the flexible circuit board will be subject to a large stress during the bending process. Under the action of this stress, the signal lines inside the flexible circuit board (such as power signal lines) , data signal lines and control signal lines, etc.) may be broken, which will lead to failure of the flexible display panel

Abstract

The invention discloses a display device, relates to the technical field of display, and can reduce the risk of breakage of an internal circuit of a flexible circuit board in the bending process and reduce the risk of display failure of the display device. The display device includes a display panel, a first printed circuit board, a second printed circuit board, and a flexible circuit board, wherein the flexible circuit board comprises a fold part, a first flat part and a second flat part, and the first flat part and the second flat part are located on two sides of the fold part in the first direction respectively and electrically connected with the fold part; at least part of the wrinkle part and the bent part are arranged side by side, and the wrinkle part comprises a plurality of corrugated structures which are sequentially connected in the first direction. In the wrinkle part, the height of the corrugated structure in the middle is greater than that of the corrugated structures at the two ends. The manufacturing method is used for manufacturing the display device.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device. Background technique [0002] With the development of flexible display technology, foldable display products have received more and more attention. A foldable display device includes a flexible display panel and a plurality of circuit boards. The flexible display panel includes a bending portion and a first non-bending portion and a second non-bending portion respectively located on two sides of the bending portion. The plurality of circuit boards includes a first circuit board electrically connected to the first non-bent portion, a second circuit board electrically connected to the second non-bend portion, and a flexible flexible circuit board electrically connected to the first circuit board and the second circuit board. circuit board. [0003] During the bending process of the foldable display device, the flexible circuit board will be bent ...
