AI Technical Summary

Technical Problem

When existing display modules realize ultra-narrow frames and ultra-thin displays, the reduction in the back film thickness leads to insufficient adhesion, affecting the bending reliability of the display panel, and the concentration of stress at the bent parts may lead to fracture.

Method used

A display module is designed, adopting a structure including a display panel, a back film and a support structure layer. The display panel consists of a first flat portion, a bent portion and a second flat portion. The back film is attached to the side opposite the second flat portion and the first flat portion. The side of the support structure layer facing away from the first flat portion is provided with a receiving groove, and at least part of the back film is located in the receiving groove. Meanwhile, the angle between the second flat portion and the bending direction is greater than 0° and less than or equal to 30° to avoid stress concentration.

Benefits of technology

The ultra-thin and ultra-narrow frame display of the display module is realized, while improving the reliability of use, avoiding the problem of separation of the back film and display panel, and reducing the risk of stress concentration in the bent areas.

Abstract

The utility model relates to a display module and a display device. The display module comprises a display panel, the display panel comprises a first flat unfolding part, a bending part and a second flat unfolding part, the first flat unfolding part is provided with a light emitting side and a backlight side, the backlight side of the first flat unfolding part and the second flat unfolding part are oppositely arranged, and the first flat unfolding part and the second flat unfolding part are connected through the bending part; the back film comprises a first back film, and the first back film is attached to the face, opposite to the first flat part, of the second flat part; the supporting structure layer is arranged on the backlight side of the first flattening part, a containing groove is formed in the face, away from the first flattening part, of the supporting structure layer, the containing groove is located in the edge, close to the bent part, of the supporting structure layer and extends in the first direction, and at least part of the first back film is located in the containing groove; wherein an included angle is formed between the second flattening part and the first direction, the included angle is larger than 0 degree and smaller than or equal to 30 degrees, and the first direction is the direction, pointing to the supporting structure layer, of the bending part. The thickness of the display module is small, and the use reliability is high.
