Abstract:
PROBLEM TO BE SOLVED: To provide a display that reduces the size of switches on a driver IC side and improve a convergence property of a potential variation to a GND potential.SOLUTION: A display comprises: a plurality of driving electrodes COML1 to COMLn for display and touch detection; a driving electrode driver 15 that applies a driving signal to each of the plurality of driving electrodes COML1 to COMLn; and a driving signal selector part 16U and a driving signal selector part 16L that select each of the plurality of driving electrodes COML1 to COMLn to which the driving electrode driver 15 applies the driving signal. On a substrate on which the plurality of driving electrodes COML1 to COMLn are formed, a ground wiring GND is formed to which the driving electrode selected by the driving signal selector part 16U is connected during a touch detection period.SELECTED DRAWING: Figure 8
