Abstract
A light guide module includes a light guide element and a light source. The light guide element includes a first light guide layer and a second light guide layer. The second light guide layer is disposed on the first light guide layer. The refractive index of the first light guide layer is greater than the refractive index of the second light guide layer. The light source is disposed in the first light guide layer.
Claims20
A light guide module applied in a reflective display panel, comprising:
- a light guide element comprising a first light guide layer and a second light guide layer, wherein the second light guide layer is disposed on the first light guide layer, and a refractive index of the first light guide layer is greater than a refractive index of the second light guide layer;
- a light source disposed within the first light guide layer, wherein the first light guide layer is closer to the reflective display panel than the second light guide layer;
- and
- a light blocking layer disposed at a side of the light guide element facing away from the reflective display panel.
