Abstract: A balun structure and an electronic device. The balun structure includes: a dielectric substrate; a first grounding conductive layer, a first transmission line, a second transmission line, and a third transmission line, wherein at least one coupling structure is connected in series between a first end and a second end of the third transmission line. The coupling structure includes a first coupling part and a second coupling part, wherein in the same coupling structure, one end of the first coupling part facing the second coupling part has at least one first branch line, and one end of the second coupling part facing the first coupling part has at least one second branch line; and in the same coupling structure, the first branch line of the first coupling part is in coupling connection with the second branch line of the second coupling part.

Abstract: The present disclosure relates to a backlight module. The backlight module is configured for use in a transparent display device and comprises: an optical splitter; and a light source arranged at a side of the optical splitter and emitting light towards the optical splitter. The optical splitter is configured to split light emitted from the light source into a first light beam and a second light beam, wherein the first light beam is configured for supplying backlight, and the second light beam is configured for illuminating background behind the optical splitter. The present disclosure also relates to a transparent display device, comprising the above described backlight module; as well as an array substrate and a color film substrate arranged in front of the backlight module.
