Abstract: The present invention provides an organic light emitting diode (OLED) display array substrate, a manufacturing method of the same OLED structure and a display apparatus. The OLED array substrate includes a plurality of pixels arranged in an array on a base substrate. Further, each pixel comprises a first sub-pixel and a second sub-pixel displaying different colors. Each sub-pixel comprises a light emitting unit and a control circuit. In addition, an orthogonal projection of the light emitting unit of the first sub-pixel on the base substrate overlaps with an orthogonal projection of the control circuit of the second sub-pixel on the base substrate. According to the OLED display structure of the present disclosure, the region occupied by the control circuit of a second sub-pixel is used to set up the light emitting unit of the first sub-pixel. This can increase the display surface area occupied by the light emitting units in each pixel, thus improve the resolution of the display.
