System and Method for Scanning Control of a Capacitive Touch Panel
First Claim
1. A system for scanning control of a capacitive touch panel, said device comprising:
- a driving unit, simultaneously driving a partially neighboring of a plurality of first axial conductive strips of said capacitive touch panel, wherein said plurality of first axial conductive strips are parallel to each other; and
a first detecting unit, detecting one of said partially neighboring of first axial conductive strips, said plurality of first axial conductive strips detected by said first detecting unit with the same effect resulted from the decay of said first detecting unit.

Abstract
This invention provides a system for scanning control of a capacitive touch panel. The system includes a driving unit driving a partially neighboring of a plurality of first axial conductive strips of the capacitive touch panel, wherein the plurality of first axial conductive strips are parallel to each other, and a first detecting unit detecting one of the partially neighboring of first axial conductive strips. By doing so, the influence caused by unintended conducting materials can be kept from the touch point detection for the capacitive touch panel, and the electro-magnetic interference of the capacitive touch panel can be also decreased.
