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.

Abstract: A phase shifter includes a signal line and a reference electrode respectively disposed on sides of different ones or both disposed on a same side of a same one of a first base plate and a second base plate proximal to a dielectric layer, and includes a straight unit and a bent unit along an extending direction of the signal line. The signal line includes a first signal sub-line corresponding to the straight unit and a second signal sub-line corresponding to the bent unit, and the reference electrode includes a first reference sub-electrode corresponding to the straight unit and a second reference sub-electrode corresponding to the bent unit. The second signal sub-line and the second reference sub-electrode which correspond to the bent unit are configured to make an impedance of the bent unit match to an impedance of the straight unit and/or an impedance of another adjacent bent unit.
