Abstract: A pixel arrangement structure for a display device. The pixel arrangement structure may comprise a first pixel and a second pixel. The first pixel and the second pixel are alternately in a row direction and a column direction. The first pixel and the second pixel each comprise a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel, the second sub-pixel, and the third sub-pixel in the first pixel form a triangular distribution. The first sub-pixel, the second sub-pixel, and the third sub-pixel in the second pixel form an inverted triangular distribution relative to the triangular distribution in the first pixel. The second sub-pixel and the third sub-pixel in each of the first pixel and the second pixel are located on substantially the same row.

Abstract: A top-emitting organic electroluminescent display panel, a manufacturing method, and a display device. The top-emitting organic electroluminescent display panel comprises: a substrate, a layer of white organic light emitting diodes and a thin film encapsulation layer arranged on the substrate in sequence. The thin film encapsulation layer comprises at least two inorganic thin film layers and at least one organic thin film layer. At least one organic thin film layer is a color filter layer, the color filter layer being arranged between the at least two inorganic thin film layers. Since one of the organic thin film layers in the thin film encapsulation layer is a color filter layer, the color filter layer does not have to be arranged above the thin film encapsulation layer separately, thus reducing the number of film lavers, simplifying the film layer structure, reducing manufacturing costs, and improving the luminous efficiency and the display effect.
