A front light module includes a light guide plate, a light source, first waterproof layers, a second waterproof layer, and a third waterproof layer. An edge of the light guide plate has an extending portion. The light source is located on the edge of the light guide plate. There are two first waterproof layers respectively located on a bottom surface and a top surface of the light guide plate. The second waterproof layer has a concave portion. The light source is located between the second waterproof layer and the edge of the light guide plate, and the extending portion of the light guide plate extends into the concave portion of the second waterproof layer. The third waterproof layer is located in the concave portion of the second waterproof layer and surrounds the extending portion of the light guide plate.

Front light module and manufacturing method thereof

A display device includes a display panel, a front light module, and a cover structure. The front light module is located on the display panel. The front light module includes a light guide thin film and a light source. The light guide thin film has a thickness. The light guide thin film includes a top surface and an irregular protrusion structure located on the top surface. The irregular protrusion structure has a stripe feature direction in a plan view, and the irregular protrusion structure has a height difference. The light source is configured to emit a light beam traveling in a direction parallel with the stripe feature direction of the irregular protrusion structure. The cover structure is located on the front light module.

Display device and mounting method of the same

A light source module, including a circuit board, a light-emitting element, a light-guiding plate, a first waterproof layer, a second waterproof layer, and a third waterproof layer, is provided. The light-emitting element is configured on the circuit board. The light-guiding plate includes at least one through hole. The circuit board is configured on a first surface of the light guide plate so that the light-emitting element inserts into the at least one through hole. The first waterproof layer is located on a second surface of the light-guiding plate that is opposite to the first surface, and covers the at least one through hole. The second waterproof layer is located between the first surface and the circuit board. The third waterproof layer is located between the second surface and the first waterproof layer.

Light source module

A front light module includes a light guide plate, a light source and a light guide medium. The light guide plate includes a top surface, a bottom surface opposite to the top surface and a light incident surface adjoining the top surface and the bottom surface. The light source is disposed beside the light incident surface. A top surface of the light source and the top surface of the light guide plate have a first step therebetween. The light guide medium is between the light source and the light incident surface of the light guide plate.

Front light module and display device

A reflective display apparatus including a reflective display panel, a transparent cover plate, and a light source is provided. The transparent cover plate is disposed on one side of the reflective display panel. An air gap exists between the reflective display panel and the transparent cover plate. The light source is disposed between the reflective display panel and the transparent cover plate, and a light emitted by the light source travels towards the air gap before irradiating the transparent cover plate or the reflective display panel.
