Title:
PIXEL COMPENSATION CIRCUIT, METHOD, AND FLAT DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/128467
Kind Code:
A1
Abstract:
The present invention provides a pixel compensation circuit, method, and flat display device. The pixel compensation circuit comprises first through fourth controllable-switch control terminals connected to first through fourth scan lines, and the first terminal of the first controllable switch is connected to a data line; the first terminal of the second controllable switch is connected to the second terminal of the first controllable switch; the control terminal of a drive switch is connected to the second terminal of the second controllable switch, and the first terminal is connected to the first voltage terminal; the first terminal of the third controllable switch is connected to the second terminal of the first controllable switch, and the second terminal is connected to the first terminal of the drive switch; the second terminal of the first controllable switch is connected to the second terminal of the drive switch via a storage capacitor; the anode of an organic light-emitting diode is connected to the second terminal of the drive switch, and the cathode is grounded; the first terminal of the fourth controllable switch is connected to a second voltage terminal, and the second terminal is connected to the second terminal of the drive switch; thus unstable current of the organic light-emitting diode being caused by a threshold voltage shift is prevented, and uniform brightness of the display is achieved.
