Abstract:
A display device includes a display region in which a plurality of pixels are arrayed in a row direction and a column direction. Gate lines each configured to supply gate signals to the pixels are aligned in the row direction. Signal lines each configured to supply pixel signals to the pixels are aligned in the column direction. At least one first semiconductor force sensor is provided in the display region. At least one second semiconductor force sensor is provided in a frame region outside the display region. A detection circuit detects force applied to the display region based on a middle-point voltage between the first semiconductor force sensor and the second semiconductor force sensor.
