1. a display module, is characterized in that, comprising:

  • At least one light source, in order to provide at least one illuminating bundle;

    Light guide plate, have first surface, second surface and at least one incidence surface being connected described first surface and described second surface relative to described first surface, described illuminating bundle enters described light guide plate by described incidence surface;

    Reflecting element, is connected to described light guide plate, and in order to change the direction of propagation at least partially of described illuminating bundle, described reflecting element has multiple first reflecting surfaces tilted relative to described second surface;

    Technology of reflective display, can modulate the polarization state of described illuminating bundle to form modulated light beam, described second surface is arranged between described technology of reflective display and described first surface;

    AndReflection type polarizer, described first surface is arranged between described second surface and described reflection type polarizer, and described modulated filtered light beam is image beam by described reflection type polarizer.
