Abstract

A display module is provided including a display panel and an integrated circuit unit. The display panel is curved into a curved shape around a curvature axis and has a curved side, wherein the side also curves around the curvature axis. The integrated circuit unit is formed as a long stripe shape and has a first long side extending along an extending direction of the integrated circuit unit. The integrated circuit unit is directly or indirectly connected to the side, and the first long side extends along the extending direction of the curvature axis. Since the extending direction of the integrated circuit unit is aligned with the curvature axis, the integrated circuit unit will not be easily affected by the curvature of the display panel.

Claims
