Abstract
A pixel driving circuit and organic light-emitting diode (OLED) display apparatus having the pixel driving circuit is provided. The pixel driving circuit with 6T1C pixel structure effectively compensates the threshold voltage of the driving transistor, which drives the OLED display apparatus, to prevent the current flows through the OLED from being correlated with the threshold voltage of the driving transistor, so that the poor display image caused due to the threshold voltage shifting of the driving transistor is eliminated.
