Title:
OLED PIXEL CIRCUIT AND DRIVE METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/157613
Kind Code:
A1
Abstract:
Provided are an OLED pixel circuit and a drive method therefor, and a display apparatus. The OLED pixel circuit comprises: an initialization sub-circuit (10), which is respectively connected to a drive sub-circuit (40), a first signal end (S1), a first voltage end (V1) and an initial voltage end (Vinit), and is used for initializing the drive sub-circuit (40); a data writing and compensation sub-circuit (20), which is respectively connected to the drive sub-circuit (40), a scanning signal end (S3) and a data voltage end (Vdata), and is used for compensating for a threshold voltage of the drive sub-circuit (40); the drive sub-circuit (40), which is further connected to a light-emitting control sub-circuit (30) and the first voltage end (V1), and is used for driving a light-emitting sub-circuit (50) to emit light after obtaining the compensation for the threshold voltage; and the light-emitting control sub-circuit (30), which is further connected to the light-emitting sub-circuit (50), an enable signal end (EM), a second voltage end (V2), a second signal end (S2) and a third voltage end (V3), and is used for enabling the light-emitting sub-circuit (50) to be turned on or turned off under the control of the enable signal end (EM), the second voltage end (V2), the second signal end (S2) and the third voltage end (V3).
