The invention discloses a pixel circuit arrangement structure of an OLED folding screen and a driving method of the pixel circuit arrangement structure. The OLED folding screen comprises at least two non-folding areas and at least one folding area connected with the two adjacent non-folding areas. The compensation circuit in the non-folding area uses an LTPS pixel compensation circuit, and the pixel compensation circuit in the folding area uses an IGZO pixel compensation circuit; and in the same row, the LTPS pixel compensation circuits of all the non-folding areas are connected with the same path of GIP driving signals, and the IGZO pixel compensation circuits of all the folding areas are connected with the other path of GIP driving signals. Through organic combination of the OLED folding screen and an OLED internal compensation circuit, the aging problem of the OLED folding screen is solved by utilizing the characteristics of IGZO and LTPS semiconductors and the arrangement of Pixels. 本发明公开一种OLED折叠屏的像素电路排布结
