Problems solved by technology

[0003] When the flexible circuit board is applied to the display device, it is necessary to use the fixture indenter to bond the flexible circuit board and the display panel, but due to the flatness of the indenter and the surface of the flexible circuit board, and the shape of the indenter, the flexible circuit board will be stressed. Inhomogeneity, local deformation of the optical adhesive layer, causing print marks on the display device, affecting the display effect of the display device

Abstract

The invention discloses a display device and a display device fitting method. The display device comprises: a display module which comprises a flexible display substrate; the flexible display substrate further comprises a first sub-part, a second sub-part and a bending part connecting the first sub-part and the second sub-part; the second sub-part is located on one side, deviating from the light emitting surface of the display module, of the first sub-part; a cover plate which is arranged on one side, deviating from the second sub-part, of the first sub-part, wherein a first adhesive layer isarranged between the cover plate and the first sub-part; a flexible circuit board which is arranged on one side, deviating from the cover plate, of the first sub-part and is connected with the secondsub-part; a rigid plate body which is arranged between the flexible circuit board and the first sub-part, wherein the rigid plate body and the flexible circuit board are at least partially overlappedin the direction perpendicular to the plane where the first sub-part is located. Due to the fact that the rigid plate body is arranged between the flexible circuit board and the first sub-part, the acting force of the pressing head acting on the flexible display panel can be transmitted to the rigid plate body, the acting force is evenly dispersed through the rigid plate body, and the problem thata display module of the display device has impressions is avoided.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display device and a bonding method of the display device. Background technique [0002] FPC (Flexible Printed Circuit, flexible circuit board) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film, with high wiring density and low weight. Light, thin, good bendability. With the development of electronic products to be lighter, thinner, shorter and multi-functional integrated, printed circuit boards are also facing the challenges of high-precision, high-density, and thin-line development. Ultra-thin applications are becoming more and more extensive. It is necessary to realize the communication and interconnection of signals in a limited space, and there are more and more demand scenarios for flexible circuit boards. [0003] When the flexible circuit board is applied to the display device, it is necessary...
