Abstract: A keyboard touch electrode module includes a plurality of same electrode matrices, which are arranged along a lengthwise direction and a widthwise direction and formed by a plurality of series of first electrodes and a plurality of series of second electrodes which interlace with each other. Adjacent two of the electrode matrices in the widthwise direction are mis-aligned. The electrode matrices thereon define a plurality of key projection areas, each of which covers a same key-face electrode pattern. A touch keyboard includes a base, a plurality of keycaps, a plurality of supporting structures connected to and between the base and the keycaps, and the keyboard touch electrode module disposed between the base and the keycaps. The keyboard touch electrode module can senses a non-pressing movement on the keycaps. The keycap can move up and down relative to the base and the keyboard touch electrode module through the corresponding supporting structure.

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.

Abstract: A light-emitting keyswitch includes a board, a lifting mechanism and a cap structure. The cap structure is assembled with the lifting mechanism to be movable upward and downward relative to the board and includes a cap and a light-emitting layer. The light-emitting layer includes first and second pad layers disposed on a lateral contour surface of the cap and spaced from each other, a lower electrode layer, a dielectric layer, an electroluminescent layer, an upper electrode layer and a transparent pattern layer stacked on a top surface of the cap, and an external trace structure. The lower and upper electrode layers are connected to the first and second pad layers respectively. The external trace structure is connected to the first and second pad layers for transmitting power to the upper and lower electrode layers, so as to drive the electroluminescent layer to emit light to the transparent pattern layer.

Abstract: A luminous touch keyboard includes a baseplate, a plurality of keycaps, a plurality of support mechanisms connected between the baseplate and the keycaps, and a keyboard composite electrode module disposed between the baseplate and the keycaps and configured to sense a non-pressing movement over the keycaps and to provide light emitting through the keycaps. The support mechanism supports the keycap to move relative to the baseplate and the keyboard composite electrode module. The keyboard composite electrode module includes a light source circuit and a plurality of electrode matrices arranged along a first direction and a second direction. Two of the electrode matrices adjacent in the second direction are mis-aligned. The light source circuit includes a plurality of light sources disposed in the plurality of electrode matrices in a one-to-one manner, and the position of the light source in the electrode matrix is correspondingly the same.
