Abstract

A pixel compensation circuit and an OLED display device are disclosed. Two or more TFTs are controlled by the scanning signal output from the scanning signal line in the same row in the pixel compensation circuit proposed by the present disclosure. Further, the OLED and the storage capacitor are both connected to the reset voltage signal line. So the OLED and the storage capacitor are reset after receiving the reset voltage signal. The size of the pixel structure in the horizontal direction is compressed in the pixel compensation circuit of the present disclosure, thereby providing space for the improvement of the PPI and facilitating the design of the high PPI panel successfully.
