PIXEL UNIT CIRCUIT, DRIVE METHOD, PIXEL CIRCUIT AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/024887
Kind Code:
A1
Abstract:
A pixel unit circuit, a drive method, a pixel circuit and a display apparatus. The pixel unit circuit comprises a light-emitting element (EL), a drive transistor (DTFT), a data write-in circuit (11) and a storage capacitor circuit (12). The data write-in circuit (11) is respectively connected to a data line (Data), a gate line (Gate) and a gate electrode of the drive transistor (DTFT), for controlling, under the control of the gate line (Gate), the conduction or disconnection of the connection between the data line and the gate electrode of the drive transistor (DTFT); a first end of the storage capacitor circuit (12) is connected to the gate electrode of the drive transistor (DTFT), and a second end of the storage capacitor circuit (12) is connected to a reference voltage input end (Vref); and a second end of the light-emitting element (EL) is connected to a low level input end (VSS).
