Abstract

The invention provides a foldable display device, a preparation method thereof and a tool, the foldable display device comprises a folding area and non-folding areas located on the two opposite sidesof the folding area, and the foldable display device comprises a flexible display panel and at least one functional layer attached to the flexible display panel through a bonding layer; the foldable display device has a pre-bending state, in the pre-bending state, an included angle between the parts, corresponding to the non-folding areas on the two opposite sides of the folding area, of the foldable display device is larger than 0 degree and smaller than 180 degrees, and the stress of the part, corresponding to the folding area, of the bonding layer is smaller than or equal to a first presetthreshold value. According to the foldable display device, the risk of falling off or stripping between the film layers in the bending process is reduced, and the bending performance of the foldable display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a foldable display device, a manufacturing method thereof, and a jig. Background technique [0002] Flexible organic light emitting diode (Oraganic Light Emitting Diode, OLED) display panels have attracted widespread attention due to their bendability, and one of their most important uses is to be applied to foldable display devices. [0003] At present, when the flexible organic light emitting diode display panel is applied to a foldable display device, because the flexible organic light emitting diode display panel is repeatedly bent or kept bent for a long time during the use of the foldable display device, the flexible organic light emitting diode display panel The part corresponding to the bending area of ​​the foldable display device has a large deformation. Due to the long-term deformation state and the difference in the bending radius of each film layer in the ...
