Abstract: A hybrid stylus communicating with a touch input device according to an embodiment of the present invention may include a conductive tip that forms a capacitance with at least one of a plurality of electrodes in the touch input device, a first mode operation unit that operates with the touch input device based on a predetermined power, a second mode operation unit that operates by using a change in capacitance for at least one of the plurality of electrodes in the touch input device by the conductive tip, a switch configured to connect the conductive tip to the first mode operation unit or the second mode operation unit, a power supply unit that provides the predetermined power to the first mode operation unit, a communication unit that transmits mode conversion information for converting an operation mode of the touch input device to the touch input device, and a controller that checks the remaining amount of the power to control the switch to connect the conductive tip to the first mode operation unit when a remaining amount of the power is greater than or equal to a predetermined threshold value and to control the switch to connect the conductive tip to the second mode operation unit when the remaining amount of the power is less than the predetermined threshold, and controls the communication unit to transmit the mode conversion information to the touch input device.
