PURPOSE: The sensing circuit of a touch panel and a sensing method for the same are provided to easily acquire accurate coordinates for touched positions and to reduce the influence of external noises. CONSTITUTION: A first sensing line(112) is formed to a first direction in a sensing region. A second sensing line(114) is formed to a second direction which is perpendicular to the first direction. A first sensing electrode(116) and a second sensing electrode(118) are formed in a unit sensing region(104) which is divided by the sensing lines and are in connection with the sensing lines. First switching devices are formed at one each side of the sensing lines and apply a driving voltage to the sensing lines. The switching devices are formed at another each side of the sensing lines and outputs a bias voltage as a sensing signal based on the operation and the touch of the first switching device. |
