Abstract: A touch sensor includes a base, first sensing electrode columns (FSECs), and second sensing electrode columns (SSECs). The base includes a sensing region (SR) including a rounded corner (RC), and a non-SR outside the SR. The FSECs extend in a direction on the base, each FSEC among the FSECs including first sensing electrodes (FSEs), each FSE among the FSEs including sub-electrodes. The SSECs are alternately disposed with the FSECs on the base, each SSEC among the SSECs including second sensing electrodes (SSEs). Sub-electrodes of one of adjacent FSEs among the FSEs are electrically connected to respective sub-electrodes of another of the adjacent FSEs. A sub-electrode closest to the RC among the sub-electrodes includes a rounded edge (RE) corresponding to the RC. A SSE closest to the RC among the SSEs includes a RE corresponding to the RC, and a protrusion part protruding toward the sub-electrode including the RE.

Abstract: A display device includes a display panel including pixels. A display driver provides a data signal to the display panel. A sensor overlaps the display panel. A sensor driver transmits a driving signal to the sensor and receives sensing signals corresponding to the driving signal from the sensor. The display driver and the sensor driver share a signal line and are connected to a memory through the signal line. The display driver and the sensor driver are interconnected through a flag signal line. The sensor driver outputs a flag signal to the flag signal line to inform the display driver that the sensor driver desires to access the memory.
