Title:
PIXEL UNIT CIRCUIT, PIXEL CIRCUIT, DRIVE METHOD AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/015318
Kind Code:
A1
Abstract:
A pixel unit circuit, a pixel circuit, a drive method and a display apparatus. A pixel unit circuit comprising: a light-emitting element (OLED), of which a first end is connected to a low-level (Vss) input end; a capacitance storage module (11), of which a first end is connected to a direct-current voltage input end (VD); a drive transistor (DTFT) of which a gate electrode is connected to a second end of the capacitance storage module (11), and of which a first end is connected to a second end of the light-emitting element (OLED); a light emission control module (12), of which a control end is connected to a light emission control line (EM), of which a first end is connected to a high-level (Vdd) input end, and of which a second end is connected to a second pole of the drive transistor (DTFT), for controlling, under the control of the light emission control line (EM), whether the second pole of the drive transistor (DTFT) receives a signal from the high-level (Vdd) input end or not; and a charging compensation control module (13), respectively connected to a gate line (Gate), a data line (Data) and the gate electrode of the drive transistor (DTFT), for controlling, under the control of the gate line (Gate), whether the gate electrode of the drive transistor (DTFT) receives a signal from the data line (Data) or not.
