摘要

A display device including: a scan driver that transmits scan signals to scan lines; a data driver that data signals to data lines; and a display portion that includes pixels, respectively connected to the corresponding scan lines and corresponding data lines, and displays an image by the pixels that simultaneously emit light according to the corresponding data signals, wherein each of pixels includes: an organic light emitting diode; a first transistor that includes a gate connected to a first node, and is connected between first power and an anode of the organic light emitting diode; a second transistor that includes a gate connected to a corresponding scan line and transmits the corresponding data signal to the first node; and a first capacitor that is connected to the first node, and stores a data voltage according to the data signal.

說明書

The first transistor T11 may include a gate connected to a first node N11, a first end connected to first power ELVDD, and a second end connected to an anode of the organic light emitting diode OLED. The second transistor T12 may include a gate connected to an i-th scan line Si, a first end connected to the first node N11, and a second end connected to the second node N12. The third transistor T3 may include the gate connected to the initialization VINT, a first end connected to the second node N12, and a second end connected to the anode of the organic light emitting diode OLED.

The first capacitor Cst is connected between the initialization power VINT and the first node N11. The second capacitor Cpr is connected between a j-th data line and the second node N12. The organic light emitting diode OLED may emit light as driving current flows from the first transistor T1.

FIG. 6 and FIG. 7 are timing diagrams of an exemplary pixel driving method of a display device including the pixel of FIG. 5.

As shown in FIG. 6 and FIG. 7, the pixel PX-2 shown in FIG. 5 may be driven by substantially the same method as the driving method of the pixel PX-1, shown in FIG. 3, but rather than a common control signal line GC, initialization power VINT is connected to the third transistor T13.
