The present invention relates to an AMOLED display device and a pixel driving method thereof. The device comprises a sub-pixel unit array formed on the substrate, wherein each of the sub-pixel unit includes two secondary sub-pixel units arranged side by side and having the same color. For switching transistors in the secondary sub-pixel units of the same column, first ends of which transistors are connected in parallel to the same data line to receive a data signal. One end of each data line is connected through a first control switch unit to a data driving unit, and when the first control switch unit on a data line of odd column is turned on/off, the first control switch unit on a data line of even column is turned off/on, so that the two secondary sub-pixel units arranged side by side and having the same color emit light in an alternate manner in term of different frames of pictures. |

1. An AMOLED display device, comprising a substrate and a sub-pixel unit array formed on the substrate, wherein:
each of the sub-pixel unit includes two secondary sub-pixel units arranged side by side and having the same color, and each secondary sub-pixel unit is correspondingly connected to a scan line and a data line; for switching transistors in the secondary sub-pixel units of the same column, first ends of which switching transistors are connected in parallel to the same data line to receive a data signal output by a data driving unit, and control ends of which are correspondingly connected with their respective scan lines arranged along the scanning direction to receive a scan signal output by a scan driving unit sequentially, and wherein under the action of the scan signal, the data signal is transmitted to a driving transistor in the related secondary sub-pixel unit, so as to drive an organic light emitting diode in the related secondary sub-pixel unit to emit light; and one end of each data line is connected to an output end of the data driving unit through a first control switch unit, and wherein when the first control switch unit on a data line of odd column is turned on/off, the first control switch unit on a data line of even column is turned off/on, so that two secondary sub-pixel units arranged side by side and having the same color emit light in an alternate manner in term of different frames of pictures. |
