The cover layer 10 is a hollow structure, and the hollow shape is a character or a pattern to be displayed, so that the light source of the luminescent structure 20 is transmitted out. For example, a "Z" shaped through hole is cut in the cover layer 10 to allow light of the luminescent structure 20 to pass through, thereby displaying a "Z".

The cover layer 10 may be designed to be hollowed out by exposure or etching, or by laser engraving or other processing methods. In one embodiment, the hollow structure is processed by laser engraving. Specifically, the covering layer 10 is engraved with font symbols such as letters, numbers, and chinese character codes, and font symbols corresponding to letters, numbers, and chinese character codes may be directly engraved, or a plurality of through holes may be engraved to form corresponding font symbols such as letters, numbers, and chinese character codes. It is understood that the hole-engraved structure on the cover layer 10 is only required to allow the luminescent structure 20 to show letters, numbers, Chinese character codes and other characters and symbols, and is convenient to use, and is not particularly limited herein.

Referring to fig. 2, the luminescent structure 20 includes a conductive layer 21, a first electrode layer 22, a luminescent layer 23, a dielectric layer 24, a second electrode layer 25 and an insulating layer 26, which are sequentially disposed, where the conductive layer 21 is used for conducting electricity, and in an embodiment, the conductive layer 21 is Indium Tin Oxide (ITO), and the Indium Tin Oxide (ITO) has good conductivity and transparency, and when used as a transparent conductive film, reduces electronic radiation harmful to a human body, ultraviolet radiation and infrared radiation.
