Abstract: The present disclosure provides an optical module and a reflective display apparatus that relate to the technical field of display and may improve the display effects in a dark environment to enhance the contrast of the display apparatus. The optical module includes a light guide plate, a light emitting unit arranged at a lateral side of the light guide plate, and an optical film and a scattering film stacked in sequence on the light guide plate, wherein the optical film is configured to reduce an incident angle of incident light and the scattering film is configured to scatter the incident light, the optical film being arranged between the light guide plate and the scattering film.

Abstract: The present disclosure provides a light source, a backlight module and a display apparatus. The light source includes: a light emitting diode chip; and a fluorescent powder layer arranged to face towards the light emitting diode chip and configured to receive a first light emitted from the light emitting diode chip and to emit a second light with a wavelength different from that of the first light, wherein the light emitting diode chip and the fluorescent powder layer are moveable with respect to each other such that quantity of fluorescent powder in the fluorescent powder layer excited by the light emitted from the light emitting diode chip increases or decreases. In the above solution, the light emitting diode chip and the fluorescent power layer are movable with respect to each other, so as to adjust color temperature of backlight conveniently.

Abstract: A transparent display device, comprising a display panel for transparency display, a base and a system light source; one side edge of the display panel being mounted to the base; the system light source comprising a first light source; wherein the first light source is mounted on a side edge of the display panel away from the base, and/or is mounted to the base and located at the light incident side of the display panel, light emitted from the first light source is irradiated onto the display panel after reflection by an object placed at the light incident side of the display panel to form a spatial light.

Abstract: A light guide plate, a backlight module and a display device both comprising the light guide plate are disclosed. The light guide plate comprises a light emitting surface and multiple side surfaces perpendicular to and connected to the light emitting surface, the side surfaces including at least one first side surface and at least one second side surface. The light guide plate further comprises at least one set of folded surfaces perpendicular to and connected to the light emitting surface. Each set of folded surfaces is connected between a pair of first side surface and second side surface which are adjacent with each other. Each set of folded surfaces includes multiple light incident surfaces which are connected one by one. In the light incident surfaces in same set of folded surfaces, any two adjacent light incident surfaces form an acute angle opened toward inside of the light guide plate.
