Title:
PIXEL CIRCUIT, DISPLAY DEVICE PROVIDED THEREWITH, AND PIXEL CIRCUIT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/065596
Kind Code:
A1
Abstract:
In a pixel circuit (10), TFTs (12-16) are connected and driven in such a way that a threshold holding capacitor (19) of capacitance value c1 holds a threshold voltage Vth of a TFT (11) which is a driving transistor, and a data holding capacitor (18), which has a capacitance value c2, holds voltages including data potentials Vdata indicating an image to be displayed, and said TFTs are connected in such a way that, during light emission, charge of the data holding capacitor (18) and the threshold holding capacitor (19) is redistributed. By this means, the potential obtained by multiplying the data potential Vdata by c1/(c1+c2) is given to the gate potential of the TFT (11).
