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.
