Title:
A display module and a guide apparatus
Document Type and Number:
Japanese Patent JP6023775
Kind Code:
B2
Abstract:
A display module (100) is provided. A light source (110) is configured to provide an illumination beam. A light guide plate (120) has a first surface (122), a second surface (124) opposite to the first surface, and an incident surface (126) connecting the first surface and the second surface. The illumination beam enters the light guide plate through the incident surface. A reflective element (130) is connected to the light guide plate and has a plurality of first reflective surfaces (131) 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 (150), and the reflective polarizer filters the modulated beam into an image beam.
