Flexible display device and manufacturing method

Abstract

The present invention provides a flexible display device, including a display area and a bending area connecting the display area, and the flexible display device also includes a flexible display panel, a touch panel, a first barrier plate, and a first protective adhesive layer; wherein A second protective adhesive layer is also provided on the display area and near the edge of the bending area, and the second protective adhesive layer is located on the lower surface of the flexible display panel. The present invention also provides a method for preparing a flexible display device, which coats an adhesive material on the lower edge of the protective adhesive layer in the bending area, reducing the position of the flexible display panel along the thinner protective adhesive layer when it is bent. The risk of circuit breakage caused by dead folds further improves the reliability of the flexible display panel after bending.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display device and a preparation method. Background technique [0002] With the development of society and the continuous improvement of human needs for material life, today's display technology is moving towards narrow borders, high contrast, high resolution, full-color display, low power consumption, high reliability, long life, and thin and light The direction of the field is moving rapidly, and the research on flexible display technology is also constantly improving and deepening. Flexible display panels can be used in many fields by virtue of their bendability, such as rollable display devices, flexible wearable devices, and foldable displays. At present, in the prior art, in the process of preparing a flexible display device, before bending the flexible display panel, a layer of protective adhesive layer is first applied to the corresponding bending area on the...

Problems solved by technology

[0004] The present invention provides a flexible display device and a preparation method, which can apply adhesive material on the joint surface of the lower edge barrier plate of the protective adhesive layer in the bending area and the flexible display panel to compensate for the thinner protective adhesive layer at the lower edge of the bending area In order to solve the problem of the existing flexible display device and its preparation method, when the glue is coated on the bending area of ​​the flexible display panel, the glue at the edge will rely on the self-overflow coating of the glue to produce an uncontrollable slope, resulting in The glue on the edge is thinner, which further makes the flexible display panel bend in the bending area, and the bending along the thinner protective glue layer produces dead folds, which causes line breakage, and further causes the technical problem of abnormal quality of the flexible display device
