  • Publication number: 20210292883
    Abstract: A method for controlling stretching of a mask includes: obtaining actual position information of at least one opening of the mask; determining an actual offset of each opening according to actual position information of the opening and preset position information of a light-emitting region of a sub-pixel corresponding to the opening; determining whether the actual offset of the opening is less than or equal to a theoretical maximum offset of the opening; and in response to determining that the actual offset of the opening is less than or equal to the theoretical maximum offset of the opening, generating a first end command for ending a process of stretching the mask.

  • Publication number: 20210288297
    Abstract: A display substrate, a method and a device for manufacturing the display substrate, and a display device are provided. The method includes shielding a to-be-cut region of a to-be-evaporated substrate with a shielding member and evaporating a common layer material onto the to-be-evaporated substrate to form a common layer of the display substrate. The display substrate includes the to-be-cut region and a display region surrounding the to-be-cut region, and the common layer material is deposited onto the display region rather than the to-be-cut region.

  • Publication number: 20210280644
    Abstract: A pixel layout structure includes a plurality of first sub-pixels, a plurality of second sub-pixels, and a plurality of third sub-pixel, which are arranged as a plurality of first repeat units, each including a first sub-pixel and a second sub-pixel, and further as a plurality of second repeat units, each including a third sub-pixel and a second sub-pixel. The first repeat units and the second repeat units are alternately arranged along a first direction and a second direction intersecting with it. The second sub-pixels are arranged in a matrix along the first direction and the second direction. Every four second sub-pixels surround one first sub-pixel or one third sub-pixel, and the first sub-pixels and the third sub-pixels are alternately arranged in the first direction and the second direction.

  • Patent number: 11081530
    Abstract: A pixel arrangement structure, a display panel, a mask component, and an evaporation apparatus are provided. The pixel arrangement structure includes a plurality of sub-pixels arranged in a row direction and a column direction. The plurality of sub-pixels are divided into a plurality of rows of sub-pixel groups. Each of rows of sub-pixel groups include at least two rows of the sub-pixels, and include a plurality of repeating units arranged in sequence, and each of the repeating units includes at least two sub-pixel groups of different colors. Each of the sub-pixel groups includes at least two sub-pixels of a same color that are located in at least two rows and are adjacently arranged, and sub-pixels adjacent to each other and having different colors, which are located in sub-pixel groups of different colors, constitute one pixel.
