摘要： 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.

摘要： Embodiments of the present disclosure provide an array substrate and a manufacturing method thereof, and a display device. The array substrate includes a base substrate, a first electrode pattern, a second electrode pattern, and an active layer pattern disposed on the base substrate, a first electrode protection pattern coating the first electrode pattern, and a second electrode protection pattern coating the second electrode pattern. The active layer pattern is disposed between the first electrode pattern and the second electrode pattern. The first electrode protection pattern and the second electrode protection pattern are connected to two sides of the active layer pattern, respectively. The problem that, the active layer pattern cannot be connected to the first electrode pattern and the second electrode pattern due to the surface oxidation, when the first electrode pattern and the second electrode pattern adopt material with low resistance characteristic, is avoided, thus increasing the product yield.
