Patent ID: 8654088

Claim:
A display comprising: first and second substrates disposed opposite each other; a display section having a plurality of pixels in a region where the first substrate and the second substrate are disposed opposite each other, each of the plurality of pixels having a first electrode and a second electrode; a switch in the region where the first substrate and the second substrate are disposed opposite each other, the switch having two electrodes placed in electrical communication by a pressure from outside the display to close the switch, one of the two electrodes of the switch connected to a data line; a detecting section configured to compare a signal from the switch with a reference signal to determine whether the switch is closed or not before writing data to a pixel of the display section through the data line, the signal obtained through the data line; and a precharge section configured to apply a precharge potential to a data line connected to one of the electrodes of the switch before writing data to the pixel of the display section through the data line, wherein, one of the electrodes of the switch is connected to (i) the first electrode of the pixel of the display section, and (ii) the data line through the first electrode, the other electrode of the switch is connected to the second electrode of the pixel, and the precharge potential is applied to the data line, the signal from the switch is compared to the reference signal, and the data is written to the pixel of the display section in this order.
