A keyswitch includes a board, a cap, and a support device. The support device is disposed between the board and the cap and includes first and second support members movably connected to the cap and the board. A stopping member is formed on one of the first support member and the cap. An elastic member is formed on the other one of the first support member and the cap. When the cap is not pressed, the stopping member abuts against the elastic member to keep the cap at a non-pressed position. When the cap is pressed to a pressed position, the cap and the first support member slide relatively to make the stopping member deform the elastic member. When the cap is released, the elastic member drives the cap and the first support member to slide relatively, so as to move the cap back to the non-pressed position.

A voltage transformer includes a magnetic core body, a positioning plate, a first coil, and a second coil. The magnetic core body has an accommodation space and a rod portion extending along a Z axis. The positioning plate extends along an X-Y plane and has a first end portion, a second end portion, and a positioning hole. The first end portion has a first A hole; the second end portion has a first B hole; the rod portion penetrates through the positioning hole. The first coil has a first winding portion, a first A wire portion, and a first B wire portion. The first winding portion is accommodated in the accommodation space and extends substantially along the X-Y plane. The rod portion penetrates through the first winding portion. The second coil has a second winding portion and a second wire portion. The second winding portion is accommodated in the accommodation space and extends substantially along the X-Y plane. The rod portion penetrates through the second winding portion. The second wire portion protrudes toward the second end portion out of the magnetic core body. The first A wire portion penetrates through the first A hole and the first B wire portion penetrates through the first B hole.

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.

A backlit keyboard includes a baseplate, a light guide plate, a light source, a reflective layer, and a light mask layer. The light mask layer is disposed between the baseplate and the light guide plate. The edge of the light mask layer forms a U-shaped reflective concave pointing downward and extending around the lateral surface of the light guide plate, and a portion of the lateral surface horizontally projects on the U-shaped reflective concave, thus allowing the U-shaped reflective concave to reflect lights leaving the lateral surface of the light guide plate back to the light guide plate. A backlight module for providing backlights to the backlit keyboard and an assembly method of the backlight module are also provided.

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.

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.
