Patent ID: 7545351

Claim:
A display device comprising: a plurality of data lines for transmitting data signals; a plurality of first scan lines for transmitting selection signals; and a plurality of pixel circuits respectively coupled to the data lines and the first scan lines, wherein at least one of the plurality of pixel circuits comprises: an emission device for displaying an image corresponding to data currents supplied thereto; a first switch for transmitting at least one of the data signals transmitted through the data lines in response to at least one of the selection signals of at least one of the first scan lines; a transistor having a first transistor electrode and a control electrode; a first storage device coupled between the first transistor electrode and the control electrode of the transistor, and for storing a first voltage corresponding to the at least one data signal from the first switch; a second storage device between the control electrode of the transistor and a second scan line for transmitting a first control signal, and for switching the first voltage of the first storage device into a second voltage by coupling with the first storage device when the first control signal is changed into a second level from a first level; and a second switch for transmitting a current outputted from the transistor to the emission device in response to a second control signal, wherein the first control signal is maintained at the first level during a horizontal period.
