    Abstract: An array substrate, a display screen and a display device. The array substrate includes a base substrate, a non-transparent first OLED substrate, and a transparent second OLED substrate. The first OLED substrate at least partially surrounds the second OLED substrate. The second OLED substrate includes a first electrode layer located on the base substrate, a light emitting structure layer located on the first electrode layer, and a second electrode layer located on the light emitting structure layer. The first electrode layer includes a plurality of first electrodes. The light emitting structure layer includes a plurality of light emitting structures. A number of the first electrodes is less than a number of the light emitting structures. Each of the first electrodes corresponds to one of the light emitting structures.

    Abstract: A mask plate and an evaporation system. The mask plate includes at least one mask strip. Folding structures are connected to two opposite sides of the at least one mask strip. At least one group of effective evaporation area and transition area located around the effective evaporation areas are arranged on the at least one mask strip. Each folding structure includes a foldable part and a support part connected to each other. The foldable part is connected to the support part and the mask strip. The foldable part and at least part of the support part are sequentially stacked on one side of the two opposite sides of the mask strip, and the foldable part covers at least part of the transition area close to the folding structure of the mask strip.
