Abstract: An organic electroluminescent display device and a manufacturing method thereof are disclosed. The organic electroluminescent display device includes a substrate, a first thin film transistor disposed on the substrate, a second thin film transistor disposed on the first thin film transistor, a first light emitting element electrically connected with a drain of the first thin film transistor, wherein the first light emitting element comprises a first electrode, a first light emitting layer and a second electrode which are stacked, a second light emitting element electrically connected with a drain of the second thin film transistor, wherein the second light emitting element is disposed on the second thin film transistor and comprises a third electrode, a second light emitting layer and a fourth electrode, wherein the second light emitting element is configured to emit white light. By forming the second light emitting element on the second thin film transistor, an original non-display region of the organic electroluminescent display device becomes a display region, as a result, an aperture ratio of the organic electroluminescent display device is increased, and the display effect of the organic electroluminescent display device is improved.

Abstract: A mask cleaning apparatus and a mask cleaning method are provided. The mask cleaning method comprises: placing a mask (100) on a stage (20); and ejecting a dry ice particle group including a plurality of dry ice particles (101) toward a surface of the mask (100) at a speed of 340 m/s to 1000 m/s, within a cleaning time, wherein the plurality of dry ice particles (101) impact the surface of the mask (100) so as to remove a contaminant on the surface of the mask. Thereby, the mask cleaning apparatus and the mask cleaning method provided by embodiments of the present disclosure can remove the contaminant on the mask, without increasing a contamination medium and damaging the surface of the mask.

Abstract: The present disclosure provides a pixel arrangement structure, a display panel and a display device. The pixel arrangement structure includes a plurality of first sub-pixels, a plurality of second sub-pixels and a plurality of third sub-pixels. Each pixel includes one first sub-pixel, each second sub-pixel is shared by at least two adjacent pixels and each third sub-pixel is shared by at least two adjacent pixels. A density of the sub-pixels is 1.5 times larger than a density of the pixels in a first direction of a pixel array, and a density of the sub-pixels is 1.5 times larger than a density of the pixels in a second direction of the pixel array. The first direction is different from the second direction.
