Abstract: The present disclosure relates to the field of display technology, and provides a photographic camera and a display device. The photographic camera includes a photographic unit and a light control structure disposed at a light entrance side of the photographic unit. Specifically, the light control structure includes a first electrode layer and a second electrode layer disposed opposite to each other, as well as an adjustment layer disposed between the first electrode layer and the second electrode layer. The first electrode layer and the second electrode layer are configured to form an electric field for controlling the light transmittance of the adjustment layer when a voltage is applied thereto.

Abstract: A light guide plate, a method of manufacturing a light guide plate, a backlight module, and a display device are disclosed. A reflective layer is provided within the light guide plate, and the reflective layer is located in the path of the parallel incident light for reflecting the parallel incident light so that the parallel incident light exits from the light exit surface. The parallel incident light is an incident light parallel to the light exit surface. Without the a reflective layer, the parallel incident light propagates linearly within the light guide plate and exits from the opposite surface of the light entrance surface. The reflective layer changes the original linear path of the reflective layer and makes the parallel incident light continue to propagate in other directions within the light guide plate.
