摘要： A light source device includes a light guide plate, an optical adhesive, and a light source element. The light guide plate includes a light guide substrate and an enhancement layer. The light guide substrate has a light incident surface, a first surface, and a second surface. The first surface is opposite to the second surface, and the light incident surface extends between the first surface and the second surface. The enhancement layer is disposed on the light guide substrate. A thickness of the enhancement layer is from 1 micrometer to 25 micrometers and a first refractive index of the light guide substrate is greater than a second refractive index of the enhancement layer. The optical adhesive is interposed between the first surface of the light guide substrate and the optical adhesive. The light source element is disposed beside the light incident surface to emit light toward the light incident surface.

摘要： A display device has two flat regions and a bending region located between the two flat regions. The display device includes a reflective display device, a cover structure, and a light guide plate. The cover structure is located above the reflective display device. The light guide plate is located between the reflective display device and the cover structure. The light guide plate has a microstructure, and the microstructure is located on a top surface of the light guide plate close to the cover structure. The microstructure has a plurality of second microstructures located at the bending region, and the sizes of the second microstructures vary along with the distances between the second microstructures and a center position of the light guide plate.

摘要： A lighting module includes a circuit board, a light emitting diode, a light guide plate and a glue material. The light emitting diode is disposed over the circuit board, and the light emitting diode includes a light emitting side surface and a non-light emitting side surface. The light guide plate is substantially parallel to the circuit board, and a portion of the light guide plate is disposed over the circuit board and adjacent to the light emitting side surface of the light emitting diode. The glue material covers and is in contact with the non-light emitting side surface of the light emitting diode and the portion of the light guide plate.
