Abstract: A lighting keyboard includes a backlight module and two rows of keyswitches. The backlight module includes a lighting board and a shielding sheet. The lighting board includes plural illuminants aligned into two rows to correspond to the two rows of keyswitches. The shielding sheet includes plural first outlet windows and plural first block patterns disposed within the first outlet windows respectively and form a first row pattern collectively. Each of the first block patterns respectively corresponds to one of the illuminant. The shielding sheet includes at least one second outlet window and plural second block patterns respectively disposed within the at least one second outlet window and formed a second row pattern collectively. Each of the plural second block patterns respectively correspond to one of the plural illuminants. A first window length of the entire contour of the plural first outlet windows is as long as a second window length of the at least one second outlet window. And the first row pattern is not identical to the second row pattern, thereby providing consistent contour halos for the two rows of keyswitches.

Abstract: A mute-able input device with keystroke tactile feedback includes: a plurality of keys, each including a tactile structure and a sound-generating structure for respectively generating operational tactile feedback and operating sounds; a plurality of adjusting mechanisms, each including an adjusting portion corresponding to one of the keys; at least one switching unit including an operating portion and a switch member, the operating portion connecting the switch member and the adjusting mechanism, the switch member generating a switching signal involving a mode switching between different tactile modes or different sound modes for one or more keys. When the operating portion moves in response to a force, the switch member is triggered to achieve the mode switching; meanwhile, the adjusting portion moves to interfere with at least one of the tactile structure or the sound-generating structure along with the movement of the operating portion.

Abstract: An optical keyswitch includes a keycap, a support mechanism, and a switch module. The support mechanism is disposed below the keycap and configured to support the keycap moving upward and downward, the support mechanism comprising a first frame and a second frame, the first frame having a sliding end. The switch module includes a circuit board, an emitter, and a receiver, the emitter and the receiver are electrically connected to the circuit board, and the emitter emitting an optical signal to the receiver. When the keycap is pressed, the first frame is driven by the keycap to slide substantially parallel to the circuit board and block the optical signal with the sliding end, so the switch module is triggered to generate a triggering signal.

Abstract: A touch keyboard includes a keyboard touch electrode module and keyswitches arranged along lengthwise and widthwise directions. The keyboard touch electrode module includes plural key electrode matrixes one-to-one corresponding to plural key projection areas for the keyswitches. The key electrode matrixes are arranged along the lengthwise direction and the widthwise direction. At least two key electrode matrixes unaligned in the widthwise direction are identical to each other. The key electrode matrix includes plural electrodes arranged alternately at an electrode interval. A size of the electrode in the widthwise direction is defined by a function of the electrode interval, a key pitch between two widthwise-adjacent ones of the key projection areas, and an electrode row number covered within the key pitch.
