CAPACITANCE DISTRIBUTION DETECTION METHOD, CAPACITANCE DISTRIBUTION DETECTION CIRCUIT, TOUCH SENSOR SYSTEM, AND INFORMATION INPUT/OUTPUT DEVICE

摘要

A capacitance distribution detection circuit (2) includes a multiplexer (4), a driver (5), and a sense amplifier (6), and the multiplexer (4) switches states between a first connection state in which first signal lines (HL1 to HLM) are connected to the driver (5) and second signal lines (VL1 to VLM) are connected to the sense amplifier (6), and a second connection state in which the first signal lines (HL1 to HLM) are connected to the sense amplifier (6) and the second signal lines (VL1 to VLM) are connected to the driver (5).
