Abstract: The present invention relates to a touch panel with a discharging function, which comprises a scanning bus, a sensing bus, a control unit, and a discharging circuit. The scanning bus is used for scanning a touch frame. The sensing bus interleaves with the scanning bus, and senses at least a touched location on the touch frame. The control unit is coupled to the scanning bus and the sensing bus 20′ for controlling them. The discharging circuit is coupled to the sensing bus or/and the scanning bus, and is controlled by the control unit for releasing the charges at the touched location or/and on the relevant path between the touched location and the buses. Thereby, by using a discharging circuit for releasing charges on the parasitic capacitor, the parasitic capacitance effect is avoided. Hence, the sensing accuracy of the touch panel is increased.

Abstract: The present application provides a display driving circuit and a method for testing drivers thereof, which is applied to a control circuit for testing a first and a second driver connected in series. The control circuit transmits an enable signal, a first voltage level, and a second voltage level to the first driver for comparing a first returned voltage level and a second returned voltage level of the first driver with a first preset parameter and a second preset parameter. When the first returned voltage level is not equal to the first preset parameter or the second returned voltage level is not equal to the second preset parameter, the control circuit stops testing. Thereby, by using the voltage levels transmitted between the control circuit and the drivers, built-in self-tests may be performed, which simplifies the self-tests of the display driving circuit and no external testing device is required.
