    摘要： A key structure including a carrier, a keycap, a lifting member, and an elastic member is provided. The carrier includes a carrier body and multiple positioning hooks. The carrier body has multiple vias, and the positioning hooks are respectively disposed corresponding to the vias. Orthographic projection of each of the positioning hooks falls in the corresponding via. Each of the positioning hooks includes a first positioning portion and a second positioning portion respectively connected to two inner wall surfaces in the corresponding via. The keycap is disposed above the carrier body. The lifting member is disposed between the carrier body and the keycap. One end of the lifting member is connected to the keycap, and an other end of the lifting member is connected to the positioning hooks. The elastic member is disposed between the carrier body and the keycap.

    摘要： A keyboard includes a backlight module, a base plate, a membrane circuit disposed on the base plate, and a plurality of key structures disposed on the membrane circuit. The backlight module includes a light source, a reflective layer, a light guide layer, and a shielding layer. The light source is disposed corresponding to the light guide layer. The light guide layer is located between the shielding layer and the reflective layer. The light guide layer has a through-hole. The shielding layer and the reflective layer are in contact with each other in the through-hole of the light guide layer. The base plate is disposed on the shielding layer. The base plate has a positioning portion disposed corresponding to the through-hole of the light guide layer, which protrudes toward the reflective layer or the membrane circuit.

    摘要： A display device is provided. The display device includes a substrate, a first optical unit, a first light-emitting unit, a second optical unit, a second light-emitting unit, and a light-blocking unit. The first optical unit is disposed on the substrate and includes a first coating layer and a first light guide layer. A light-emitting region of the first light-emitting unit corresponds in position to a first light incident surface of the first light guide layer. The second optical unit is disposed on the first optical unit and includes a second coating layer and a second light guide layer. A light-emitting region of the second light-emitting unit corresponds in position to a second light incident surface of the second light guide layer. The light-blocking unit separates the first light incident surface and the second light incident surface.
