摘要： The present invention provides a source driver for use in a TFT-LCD, comprising: a data register, a data latch, a digital-to-analog converter and an output buffer. A first loading pulse is provided to the output buffer, such that the output buffer starts to output the gray-scale voltages of odd output ends to corresponding TFT sources in response to a second edge of the first loading pulse from the second level to the first level, which second edge immediately follows the first edge, and a second loading pulse is provided to the output buffer, such that such that the output buffer starts to output the gray-scale voltages of even output ends to corresponding TFT sources in response to a second edge of the second loading pulse from the second level to the first level, which second edge immediately follows the first edge. At least the second edge of the first loading pulse is not synchronous with the second edge of the second loading pulse. A driving circuit and a driving method are further provided. The source driver, the driving circuit and the driving method can alleviate adverse consequences resulting from too large difference between display data of two adjacent rows.

摘要： An array substrate, a driving method, an organic light emitting display panel and a display device. The array substrate includes a plurality of light emitting devices and pixel circuits connected with the light emitting devices, both located in a display area as well as a plurality of voltage control circuits located in a non-display area, wherein at least two of the pixel circuits in one row share one of the voltage control circuits, so that the structure of each pixel circuit in the display area can be simplified, the area occupied by the pixel circuits in the display area can be reduced, and furthermore, more pixel circuits and light emitting devices can be arranged in the display area to obtain an organic light emitting display panel with a high PPI. Moreover, due to the control of the voltage control circuits over reset control signals, initialization signals are output to first electrodes of driving transistors to control the corresponding light emitting devices to be reset, so that influences of voltages loaded on the light emitting devices during previous-frame light emission on next-frame light emission can be avoided, and furthermore, the phenomenon of residual shadows is relieved.
