Abstract: A wearable display apparatus includes a reflective light modulator having a front, a light guide plate placed at the front of the light modulator, a plurality of monochromatic light sources of different colors, and an optical assembly. The light guide plate has a first and a second major surface opposite to each other, and a light incidence surface connected with the first and second major surfaces, the light guide plate directing light received at the light incidence surface through the first major surface toward the light modulator. The monochromatic light sources are operable to emit light of different colors in a sequential manner. The optical assembly is arranged adjacent to the light incidence surface of the light guide plate, and is configured to homogenize and distribute the light emitted by each of the monochromatic light sources across the light incidence surface.

Abstract: A display module is provided. A light source is configured to provide an illumination beam. A light guide plate has a first surface, a second surface opposite to the first surface, and an incident surface connecting the first surface and the second surface. The illumination beam enters the light guide plate through the incident surface. A reflective element is connected to the light guide plate and has a plurality of first reflective surfaces inclined with respect to the second surface. A reflective display unit is capable of modulating a polarization state of the illumination beam to form a modulated beam. The second surface is disposed between the reflective display unit and the first surface. The first surface is disposed between the second surface and a reflective polarizer, and the reflective polarizer filters the modulated beam into an image beam.

Abstract: A light source module includes a light-emitting device, a light guide pipe, a wave plate, and a polarizer. The light-emitting device emits a beam. The light guide pipe includes a recessed curved surface, an output surface, a first convex surface, and a second convex surface. The recessed curved surface faces the light-emitting device. The output surface is opposite to the recessed curved surface. The first convex surface connects the recessed curved surface with the output surface. The second convex surface connects the recessed curved surface with the output surface and is opposite to the first convex surface, wherein the beam enters the light guide pipe through the recessed curved surface, and leaves the light guide pipe through the output surface. The wave plate is disposed on a path of the beam from the output surface. The polarizer is disposed on a path of the beam from the wave plate.

Abstract: A front-lit display includes a light source, a coupling lens, a first and a second polarizers, a light guide plate, and a reflective display panel. The light guide plate has a first surface, a second surface, a side surface connecting the first and second surfaces, and light guiding microstructures located between the first and second surfaces. The first polarizer, the coupling lens, and the light source are sequentially disposed at a side of the side surface. Light emitting elements of the light source that emit light beams of different colors are arranged along a first direction instead of a second direction. The first direction is parallel to the side surface and the first surface, and the second direction is parallel to the side surface and perpendicular to the first surface. The coupling lens includes vertical columnar structures arranged along the first direction and respectively extending along the second direction.
