Abstract: A backlight keyswitch includes a keyswitch body, a board connected to the keyswitch body, a backlight module and a membrane disposed between the keyswitch body and the board. The backlight module is disposed under the board and includes a backlight circuit board, a light-blocking sheet, a first reflecting ink layer, and a light guide plate disposed between the light-blocking sheet and the backlight circuit board. The first reflecting ink layer is formed on the light-blocking sheet and located above the backlight circuit board, for at least partially reflecting light emitted by the backlight circuit board back to an optical microstructure in the light guide plate to prevent center symbols of the keyswitch body from being too bright, such that light can be incident to the keyswitch body via scattering of the optical microstructure to increase brightness of side symbols of the keyswitch body.

Abstract: An illuminated touch key uses a chamfer structure of a light guide panel disposed on a sensing module or a light guide panel adjacent to a sensing module to guide light emitted by a light source to a hollow area of a keycap to emit light, thereby forming an illuminated pattern corresponding to the hollow area. Accordingly, a user can accurately find the location of the illuminated touch key according to the illuminated pattern. Since there is no need to add a light guide structure above the sensing module, the height of the illuminated touch key will not be increased, such that it is conductive to make the illuminated touch key thinner.

Abstract: A touch pad, capable of exhibiting multiple mirror images, includes a circuit board, a touch sensing circuit layer formed on the circuit board, a reflective layer disposed on the touch sensing circuit layer, an enclosed spacer, a light-guiding plate where a pattern region is formed, a partially reflective layer bonded on an upper surface of the light-guiding plate, at least one light-emitting device, and transparent top cover. The light-guiding plate is disposed within the enclosed spacer and is bonded on the reflective layer. The at least one light-emitting device is driven to emit a light into the light-guiding plate from a light-incident face. The incident light is repeatedly reflected between the partially reflective layer and the reflective layer, and finally exits from the partially reflective layer such that a user watches the pattern region and the multiple mirror images associated with the pattern region outside the transparent top cover.

Abstract: An illuminating circuit structure includes a film sheet, an illuminant, a printed baseline layer, and a printed pad layer. The printed baseline layer includes a first baseline segment and a second baseline segment printed on the film sheet, while the printed pad layer includes a first bar pad and a second bar pad. For a first baseline head of the first baseline layer and a first pad head of the first bar pad, one of which extends along a first direction and the other of which extends along a second direction not parallel to the first direction. Therefore, the first baseline segment and the first bar pad achieve electrical connection despite of an existed print shifting. Similarly, a second baseline head of the second baseline layer and a second pad head of the second bar pad also can achieve electrical connection despite of an existed print shifting.
