Keyboard composite electrode module and luminous touch keyboard therewith

A keyboard composite electrode module, comprising:

• a plurality of electrode matrices consecutively arranged along a first direction and a second direction, two of the electrode matrices adjacent in the second direction shifted from and mis-aligned with each other along the second direction, at least two of the electrode matrices mis-aligned in the second direction being identical to each other, each of the electrode matrices comprising:
• a plurality of sections of first electrode strings;
• and
• a plurality of sections of second electrode strings interlaced with the plurality of sections of first electrode strings;
• and
• a light source circuit comprising a plurality of light source wirings and a plurality of light sources disposed on the plurality of light source wirings, the plurality of light sources disposed in the plurality of electrode matrices in a one-to-one manner, and a position of the light source in each of the electrode matrices is correspondingly the same.

A luminous touch keyboard, comprising:

• a keyboard composite electrode module, comprising:
• a plurality of electrode matrices;
• and
• a light source circuit,
• wherein the plurality of electrode matrices correspond to a plurality of key projection zones in a one-to-one manner;
• the plurality of electrode matrices are arranged along a first direction and a second direction;
• at least two of the electrode matrices are mis-aligned in the second direction and identical to each other;
• the electrode matrices comprise a plurality of electrodes arranged with a same electrode gap;
• a size of the electrode in the second direction is a function of a key pitch of the key projection zones, the electrode gap, and a number of rows or columns of the electrodes covered by the key pitch;
• the light source circuit comprises a plurality of light sources disposed in the plurality of electrode matrices in a one-to-one manner;
• a position of the light source in each of the electrode matrices is correspondingly the same.
