Abstract: The present exemplary embodiments relate to a touch display device and a driving method thereof. According to the present exemplary embodiments, when a touch of the user is sensed during a touch sensing period of each frame, the touch force is sensed by being limited to an area determined based on the sensed touch position, thereby efficiently sensing the touch force. In this case, the touch force sensing is repeated for a limited area during the force sensing period of each frame, so that the touch force sensing report rate is improved. Further, the touch force sensing is performed only during the force sensing period of a frame allocated to a limited area so that power consumption according to the touch force sensing is reduced and the precision for sensing a touch force may be maintained.

Abstract: An active stylus pen generates a pen driving signal synchronized with a touchscreen driving signal received from a touchscreen and outputs the pen driving signal to the touchscreen. The active stylus pen includes a pressure sensing unit for sensing pressure when touching the touchscreen to generate writing pressure information and a signal processor for modulating the pen driving signal in response to the signal level of the writing pressure information and outputs the modulated signal as a pen driving signal in which the writing pressure information has been reflected.

Abstract: A touch sensing system comprises a touchscreen with a plurality of touch electrodes, to which a touchscreen driving signal is applied, and a stylus pen that generates a pen driving signal based on the touchscreen driving signal and sends the same to the touchscreen. The stylus pen comprises: an amplifier that amplifies the touchscreen driving signal to generate an amplified signal; a comparator that compares the amplified signal with a preset reference voltage to generate a comparator output signal; and a signal processor that measures the pulse width of the comparator output signal, adjusts an amount of delay based on a measurement, and determines an output timing of the pen driving signal based on an adjusted amount of delay to synchronize the pen driving signal with the touchscreen driving signal.

Abstract: Embodiments of the present disclosure are related to a touch display device, as a portion of a touch routing line is disposed on an area surrounded by a touch electrode line on an active area and is electrically connected to the touch electrode line, the touch routing line can be disposed on the active area while reducing an influence of a noise. Thus, as an additional arrangement of the touch routing line and a free adjustment of a connecting point of the touch routing line become possible without an increase of an area for arranging the touch routing line, a load by the touch routing line and a difference of a sensitivity according to positions of the touch electrode line are reduced and a performance of a touch sensing can be improved.
