Patent Searching and Data


Title:
PIXEL CIRCUIT, DISPLAY DEVICE PROVIDED THEREWITH, AND DRIVE METHOD OF SAID DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/021159
Kind Code:
A1
Abstract:
Provided is a pixel circuit which can maintain display quality if the mobility of the input transistor is low or even if the select period of the scan lines cannot be sufficiently ensured. This pixel circuit (11) is provided with an organic EL element (OLED), transistors (T1-T3), and a capacitor (C1). The drain terminal of the drive transistor (T1) is connected to a high-level power source (ELVDD), and the source terminal thereof is connected to the anode terminal of the organic EL element (OLED). The gate terminal of the first input transistor (T2) is connected to a scan line (Si), and said first input transistor (T2) is provided between a data line (Dj) and the gate terminal of the drive transistor (T1). The gate terminal of the second input transistor (T3) is connected to a scan line (Si-1) in the (i-1)th row, and said second input transistor (T3) is provided between the data line (Dj) and the gate terminal of the drive transistor (T1). The capacitor is provided between the gate terminal and the source terminal of the drive transistor (T1).
