AI Technical Summary

Technical Problem

Existing rollable display modules cannot simultaneously achieve both the rollability of the support components and the flatness of the display components.

Method used

The support plate is made of one piece. The support plate includes a first support layer close to the display component and a second support layer away from the display component. The spacing and thickness ratio of the first support layer and the second support layer are designed to be within a specific range. Combined with the arrangement of the hollow area, a one-piece support structure is formed.

Benefits of technology

While ensuring the flatness of the display components, the rollability of the support components was improved, the thickness of the support components was reduced, and the rollability and flatness of the display module were enhanced.

Abstract

This disclosure provides a support component, a rollable display module, and a display device, relating to the field of display technology. The support component is used to connect to the backlight side of a display component to support the display component. The support component includes an integrally formed support plate, which includes a first support layer near the display component and a second support layer away from the display component. The first support layer includes a plurality of first support ribs spaced apart along a first direction, and the second support layer includes a plurality of second support ribs spaced apart along the first direction. Both the first and second support ribs extend along a second direction, which intersects the first direction. The spacing between two adjacent first support ribs is a first spacing, and the spacing between two adjacent second support ribs is a second spacing. The ratio of the second spacing to the first spacing is greater than 1 and less than or equal to 20. Furthermore, the ratio of the thickness of the second support layer to the thickness of the first support layer is greater than or equal to 1 and less than or equal to 10.
