Abstract
A front light guide module disposed on a reflective display includes a light guide plate, a light source module, and a composite light path adjustment layer. The light source module includes a flexible circuit board and a plurality of light-emitting diodes. The light-emitting diodes are disposed on an opaque reflective surface of the flexible circuit board. A vertical distance from a top surface of each of the light-emitting diodes to the flexible circuit board is smaller than or equal to a vertical distance from a top surface of the light guide plate to the flexible circuit board. The composite light path adjustment layer includes a reflective layer and a light-shielding layer. An average brightness of the front light guide module on the reflective display is larger than 120 cd/m, with a brightness uniformity that is larger than 80%.
