摘要： An illuminated touch module includes a base sheet, a light-shielding sheet, a light guide plate, a light-emitting element, and a cover plate. The base sheet is disposed on a circuit board and has a light reflection area. The light-shielding sheet is disposed above the base sheet and has a side surface and a notch recessed from the side surface. An opening of the notch is aligned with an edge of the base sheet. The light guide plate is embedded in the notch and located above the light reflection area. The light guide plate has a light guide pattern formed by microstructures and has a light incident surface. The light-emitting element is disposed on the circuit board and has a light outputting surface facing the light incident surface and the light guide pattern. The cover plate covers above the light guide plate and the light-shielding sheet.

摘要： A backlight module includes a glass substrate, a light-outputting sheet, a light guide plate, and a reflective sheet. The light-outputting sheet is disposed under the glass substrate and has a light-outputting region and a light-shielding region. The light-outputting region is disposed corresponding to the glass substrate. The light-shielding region is disposed corresponding to an outer periphery of the glass substrate. The light guide plate is disposed under the light-outputting sheet and has a light guide region and a light mixing region. The light guide region is disposed corresponding to the light-outputting region. The light mixing region is configured to receive light of a light-emitting element and guide the light to the light guide region. The light leaves the light guide region and then sequentially propagates through the light-outputting region and the glass substrate. The reflective sheet is disposed under the light guide plate.

摘要： An illuminated trackpad includes a substrate, a light guide plate disposed under the substrate, a circuit board disposed under the light guide plate, and light-emitting elements disposed on the circuit board. The light guide plate includes light guide units and through holes. Each light guide unit is composed of light guide microstructures and substantially in the shape of a strip or a line. The through holes are respectively arranged on one side of the light guide units. The circuit board has a touch surface and a non-touch surface. The touch surface has a touch area on which sensing electrodes are disposed. The light-emitting elements are respectively accommodated in the through holes. After entering the light guide plate through inner walls of the through holes, the lights emitted by the light-emitting elements are guided upward through the light guide units to pass through the substrate and exit.

摘要： A light-emitting module includes a light-shielding sheet, a light guide plate, a light barrier, a circuit board, and first and second light-emitting elements. The light-shielding sheet includes a first pattern area and a second pattern area. The light guide plate is disposed under the light-shielding sheet and has a microstructure disposed corresponding to the second pattern area. The light barrier is disposed under the light guide plate and has first and second holes. The circuit board is disposed under the light barrier. The first light-emitting element is disposed on the circuit board, enters the first hole, and is configured to emit light toward a bottom surface of the light guide plate. The second light-emitting element is disposed on the circuit board, passes through the second hole, and is configured to emit light toward a side surface of the light guide plate.
