Abstract: A keyboard device includes M driving circuits DC(1)˜DC(M), N transition circuits TC(1)˜TC(N), a control module, M column signal lines C(1)˜C(M), N row signal lines R(1)˜R(N) and M*N key units KU(1,1)˜KU(M,N). The control module performs a scanning process to sequentially scan the M column signal lines C(1)˜C(M) in M scan cycles scan(1)˜scan(M). If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.

Abstract: A backlit keyboard includes a keyboard module having a plurality of key units and a light guide module including a light guide plate, a metal layer, and an insulation layer. The light guide plate has a light-exit surface and a bottom surface. The metal layer has an upper surface and a lower surface, wherein the upper surface is attached to the bottom surface of the light guide plate. When light is incident onto the upper surface of the metal layer, the light will be reflected back into the light guide plate. When electromagnetic wave reaches the lower surface of the metal layer, the metal layer will shield the electromagnetic wave from propagating. The insulation layer substantially covers the lower surface of the metal layer, wherein at least one ground window is formed in the insulation layer to expose the metal layer.

Abstract: A light emission module and a light guide plate and a manufacturing method thereof are provided. The light guide plate is configured to guide the light received and has a first lateral surface and a tongue extending from the first lateral surface toward a light source. The tongue has a flat end surface that faces or engages with the light source. The light guide plate receives the light emitted from the light source by the flat end surface, so as to reduce or eliminate the gap between the light source and the light guide plate. Therefore, the loss of light energy during the light traveling in air is effectively reduced, and the intensity of light received by the light guide plate from the light source meets expectation, improving the lighting effect of the light emission module.

Abstract: The keyswitch structure uses two linkages form as V-shaped to support a keycap when the keycap is moved up and down. A first linkage and a second linkage are coupled with each other and also coupled with a support on a base respectively in a line contacting way, thereby forming a first axis, a second axis, and a third axis. The third axis is located between the first axis and the second axis. As the keycap is pressed to move downward, the keycap brings the two linkages and the support of the base to have relative rotation movement. Due to the geometric feature between the three axes, part of the linkages between the axes or the support of the base may be caused to slightly deform to provide a resilient restoring force that can move the keycap upward to a position not being pressed.

Abstract: A keyswitch includes a cap, a board, first and second support members rotatably connected to the cap and the board, a seesaw member, and a magnetic member. The seesaw member movably supports at least one of the cap and the first and second support members. The magnetic member is disposed on the board corresponding to the seesaw member. When the cap is pressed, the at least one of the cap and the first and second support members drives the seesaw member to raise and the cap moves from a non-pressed position to a pressed position. When the cap is released, a magnetic attraction force between the magnetic member and the seesaw member drives the seesaw member to raise for lifting the at least one of the cap and the first and second support members, so as to move the cap back to the non-pressed position.
