AI Technical Summary

Technical Problem

Existing e-ink reflective display devices suffer from structural design issues such as unstable baffles and insufficient aperture ratio, which affect the display effect.

Method used

The design employs a combination of a first baffle with a smaller cross-sectional area and a second baffle with a larger cross-sectional area along the thickness direction of the display panel. The first baffle is located close to the display side, and the switching between bright and dark states is achieved by controlling the movement of the display particles. The aperture ratio is also improved by combining a reflective structure.

Benefits of technology

The aperture ratio and stability of the display panel have been improved, enhancing the display effect and enabling efficient bright and dark display.

Abstract

A display panel (10) and a display device (100), the display panel (10) comprising: a first substrate (1) and a second substrate (2) opposite to each other in the thickness direction of the display panel (10), and a separation barrier wall (3). The first substrate (1) is located on the display side, and the second substrate (2) is located on the non-display side; the separation barrier wall (3) is arranged between the first substrate (1) and the second substrate (2), and defines a cavity of a display unit, and the cavity is filled with a liquid material for display; the separation barrier wall (3) comprises a first barrier wall (31) and a second barrier wall (32) arranged in the thickness direction of the display panel (10) and connected to each other, the first barrier wall (31) is close to the display side, and the second barrier wall (32) is close to the non-display side; the area of the cross section of the first barrier wall (31) is smaller than the area of the cross section of the second barrier wall (32), and the cross section is perpendicular to the thickness direction of the display panel (10).
