Title:
DISPLAY DEVICE AND DRIVE METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/069560
Kind Code:
A1
Abstract:
Provided is a display device wherein uneven brightness caused by waveform blunting is eliminated. A pixel circuit (10) includes P-channel type TFTs (11-16), an N-channel type TFT (17), capacitors (21, 22), and an organic EL element (23). A scan signal and a scan inversion signal are provided, respectively, to a current scan line (Gi) that controls a TFT (12) and a scan inversion line (GIi) that controls a TFT (17). The scan signal and the scan inversion signal are each provided from the same side, relative to a display unit. When a data write operation has been completed, the TFTs (12, 13, 17) change to the off status, as a result of the potential in the current scan line (Gi) changing to a high level and the potential in the scan inversion line (GIi) changing to a low level. A field through voltage (ΔVf) is generated by the effect of parasitic capacitance connected to a gate control node (Vg).
