Abstract

A light-emitting module includes a light-emitting panel which includes a first rigid substrate, a flexible substrate, a circuit layer, a light-emitting element, and a driver chip. The flexible substrate includes a light-emitting region, a bending region, and an epitaxial region, and the light-emitting region and the epitaxial region are located on two ends of the bending region. The circuit layer includes a first connection terminal located on the epitaxial region and the driver chip is bonded to the first connection terminal. The light-emitting element is located on the light-emitting region, and the light-emitting element emits light toward the first rigid substrate. The flexible substrate is bent in the bending region and the flexible substrate in the epitaxial region is bent to a side of the light-emitting elements facing away from the first rigid substrate. The process difficulty can be reduced and the product yield can be improved.
