Patent ID: 10204555

Abstract:
A pixel circuit and driving method thereof, and a display device can achieve a threshold voltage compensation function, which facilitates reducing the pixel size of AMOLED and achieving high PPI. The pixel circuit comprises a plurality of pixel units arranged in a matrix and each including a sub-pixel unit (b) and a light emitting element (a), the sub-pixel unit (b) including a driving transistor electrically connected with the light emitting element (a), corresponding to each row of pixel units, the pixel circuit further comprises a row sharing unit (c) electrically connected with each pixel unit of the corresponding row via a first connection line; corresponding to each column of pixel units, the pixel circuit further comprises a column sharing unit (d) electrically connected with each pixel unit of the corresponding column via a second connection line; the sub-pixel unit (b), the row sharing unit (c), and the column sharing unit (d) constitute a circuit having a function of compensating for a threshold voltage of the driving transistor in the sub-pixel unit.
