Abstract
An image pixel includes an organic photodiode, a first electrode connected to a first voltage, and a second electrode connected to a second voltage. The first electrode and the second electrode are disposed on a first surface of the organic photodiode, and a read-out circuit is connected to the first electrode and the second electrode. The read-out circuit provides a first data voltage based on a first charge amount provided from the first electrode to a first data line, and provides a second data voltage based on a second charge amount provided from the second electrode to the first data line.
