Title:
DISPLAY DEVICE AND DRIVE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/073466
Kind Code:
A1
Abstract:
In a pixel circuit (10), TFTs (12, 13) and an organic EL element (15) are provided on a current path connecting a power line (VPk) and an electrode having a common potential (Vcom). The display device (100) simultaneously initializes the pixel circuits (10) of multiple rows, simultaneously detects the threshold values of the pixel circuits (10) of the multiple rows, writes data into the pixel circuits (10) for each row in order, and, during the same period, causes the organic EL element (15) included in the pixel circuits (10) of the multiple rows to emit light. During the period from completion of the threshold value detection to the start of light emission, the TFTs (11, 13) are controlled to be in the OFF state, and a potential (VP_C) approximately equal to the common potential (Vcom) is applied to the power line (VPk). By means of this configuration, leakage current in the TFTs (12, 13) is suppressed, and fluctuation is avoided in the node potential in the pixel circuit (10) during the waiting period.
