Capacitive stylus with two transmit electrodes

A capacitive stylus with two transmit electrodes, comprising:

• a circuit board with a circuit thereon;
• a first transmit electrode comprising a conductive nib, a nib holder and a conductive spring, wherein a portion of the conductive nib is in the nib holder, and the conductive spring electrically connects the conductive nib and the nib holder to the circuit;
• a second transmit electrode comprising a second transmit electrode ring and a second transmit electrode line, wherein the second transmit electrode line electrically connects the second transmit electrode ring to the circuit, the second transmit electrode ring surrounds one end of the first transmit electrode opposing to a tip of the conductive nib;
• and
• a first transmit electrode shield, wherein the first transmit electrode shield surrounds the nib holder and is configured to be located between the first transmit electrode and the second transmit electrode, the first transmit electrode shield sheaths the first transmit electrode to shield the first transmit electrode so that only a portion of the first transmit electrode adjacent the tip of the conductive nib exposes and the portion of the first transmit electrode and the second transmit electrode ring is spaced with a distance.
