Display module and display device

By placing the bending portion of the display panel within the support sheet in OLED foldable flexible electronic devices and designing differentiated bending and non-bending portions, the problem of increased mid-frame width caused by the outward expansion of the support sheet is solved, achieving a high screen-to-body ratio and protection effect for the display module.

AI Technical Summary

Technical Problem

The expansion of the support sheet in OLED foldable flexible electronic devices leads to an increase in the width of the mid-frame area, which reduces the screen-to-body ratio of the display module and the user experience.

Method used

By designing differentiated bent and non-bent portions, the width of the mid-frame area can be reduced and the screen-to-body ratio increased by placing the bent portion of the display panel within the projection of the support plate and aligning the projection of the non-bent portion with the support plate.

Benefits of technology

It achieves protection of the display panel when bent, preventing the film layer from breaking, while reducing the width of the middle frame area, improving the screen ratio of the display module and the user experience.

Abstract

Embodiments of the present application provide a display module and a display device. The display module comprises: a display panel comprising a first non-bending portion, a bending portion and a second non-bending portion connected in sequence, when the bending portion is bent, the first non-bending portion moves towards the second non-bending portion; and a support sheet arranged on the non-light-emitting side of the display panel, the support sheet is a metal support sheet, the projection of the bending portion on the support sheet is located in the support sheet, and the projection of the non-bending portion on the support sheet coincides with the support sheet. The display module can be bent, the support sheet can protect the display panel, and the film layer structure of the display panel can be prevented from being broken. The width of the middle frame area can be reduced, the screen-to-body ratio of the display module can be improved, and the user experience can be improved.
