Abstract: An interactive white board, a data processing method and device for same are disclosed. The interactive white board includes a touch component, a device processor, a first control unit and multiple first channel modules, where the touch component is configured to generate first touch data and send it to the device processor; the device processor is configured to mark the first touch data according to a current display channel to generate second touch data and send it to the first control unit, where the second touch data includes an identifier corresponding to the current display channel; the first control unit is configured to send the second touch data to a corresponding one of the first channel modules according to the identifier corresponding to the current display channel; and the first channel module is configured to receive the second touch data through the corresponding display channel and make a touch response.

Abstract: A touch panel control circuit and a touch panel. The touch panel control circuit includes a touch transfer module, a main chip and a signal source interface. An input interface (A) of the touch transfer module is configured to be connected to an output interface of a touch input device to receive a first touch coordinate signal form the output interface of the touch input device. A first transmission interface of the touch transfer module is connected to a touch information transmission interface (E) of the main chip. A second transmission interface (B2) of the touch transfer module is connected to the signal source interface.
