Abstract

Embodiments of the present disclosure disclose a transparent display apparatus. The transparent display apparatus includes a transparent display module, a light source assembly, a back frame and a front frame. The back frame and the front frame are disposed opposite to each other and are fixed to each other, and an annular accommodation groove is formed between the back frame and the front frame. An edge of the transparent display module is embedded in the accommodation groove, and is fixed to the back frame and the front frame, respectively, and at least a part of a side surface of the transparent display module serves as a light entering surface for the transparent display module displaying a picture. The light source assembly is located in the accommodation groove, and has a luminous element which is just opposite to the light entering surface.

First claim

What is claimed is:
