Abstract
There is provided a sensor pixel, including: a first transistor controlled depending on a mode selection voltage supplied to one end thereof; a second transistor including a gate connected to the other end of the first transistor; and a photoconductor connected to one end of the second transistor, wherein the sensor pixel operates in an optical mode when the first transistor is turned on, and the sensor pixel operates in a capacitive mode when the first transistor is turned off.
