DISPLAY DEVICE AND METHOD FOR DRIVING THEREOF

摘要

A display device is provided. The display device comprises: a scanning driving unit for forwarding a plurality of scanning signals to a plurality of scanning lines; a data driving unit for forwarding a plurality of data signals to a plurality of data lines; a selection driving unit for forwarding a plurality of selection signals to a plurality of selection signal lines; a sensor driving unit for receiving a plurality of output signals through the data lines; and a plurality of pixels individually connected to the scanning lines, the data lines, and the selection signal lines. Each of the pixels includes: an organic light emitting diode connected between a first power source and a second power source; a first transistor for forwarding a driving current in accordance with the data line to the organic light emitting diode; a second transistor for connecting a gate electrode of the first transistor to the data line in response to the scanning signal; a first capacitor connected between the first power source and the gate electrode of the first transistor; a light receiving element connected to a third power source; a second capacitor connected between the light receiving element and a fourth power source; a third transistor whose gate electrode is connected to the selection signal line and connected between the data line and a first electrode of the second capacitor; and a fourth transistor whose gate electrode is connected to the first electrode of the second capacitor and connected between the fourth power source and the third transistor.
