Abstract

The invention provides a display module, a manufacturing method thereof and a display device. The display module comprises a substrate, a display function layer, a supporting layer, a buffer layer and a first bonding layer. The substrate comprises a display section, a bending section and an extension section; the supporting layer is arranged on one side, far away from the display function layer, of the substrate, and comprises a first supporting layer arranged close to the extension section and a second supporting layer arranged on the display section; the buffer layer is arranged on one side, deviating from the substrate, of the second supporting layer; the first bonding layer is arranged between the first supporting layer and the buffer layer; and the distance from one end, far away from the non-display area, of the first bonding layer to the non-display area is larger than or equal to the distance from one end, far away from the non-display area, of the buffer layer to the non-display area. The technical problem that the appearance of a display module product is affected due to the fact that a buffer layer is excessively thinned in order to achieve a narrow frame effect in an existing terminal bending process, so that a bonding layer on the display module is impressed obviously is solved.

Description

technical field [0001] The present application relates to the field of display modules, in particular to a display module, a manufacturing method thereof, and a display device. Background technique [0002] With the development trend of electronic devices gradually pursuing thinner and narrower borders, due to the constraints of flexible circuit boards (FPC, Flexible Printed Circuit) & line driver array substrates (GOA, Gate driver On Array) and other constraints, the display module's lower The binding at the frame restricts the development of the narrow frame of the mobile phone. [0003] At this stage, the market mainly uses the terminal bending process to bend the FPC&GOA wiring to the back of the screen for binding to achieve the narrow border effect. In order to further reduce the width of the frame, when the terminal bending process of the display module is bound, the minimization of the bending radius is pursued, that is, the thickness of the display module is also r...
