[0067] The present invention also proposes a method for preparing an OLED unit, which includes: forming at least two light-emitting units between the first electrode layer and the anode layer, and forming a color filter layer on the surface of the first electrode layer or the second electrode layer; Wherein, the at least two light-emitting units include a first monochrome light-emitting unit; and
[0068] forming the first monochromatic light-emitting unit on the first electrode layer so that it is located in the entire pixel area;
[0069] The other light-emitting units of the at least two light-emitting units are stacked on the first monochrome light-emitting unit, so that the other light-emitting units of the at least two light-emitting units are located in the sub-units corresponding to the first monochrome light-emitting unit. Other sub-pixel areas of the pixel;
[0070] Wherein, the color filter layer is formed in the other sub-pixel area.

The invention discloses an OLED (Organic Light Emitting Diode) unit and a fabrication method thereof, an OLED display panel and an OLED display apparatus. The OLED unit comprises at least two light emitting units, a first electrode layer, a second electrode and a color film layer, wherein the at least two light emitting units are stacked between the first electrode layer and the second electrode layer, the color film layer is formed on the surface of the first electrode layer or the second electrode layer, the at least two light emitting units comprise a first monochromatic light emitting unit, the first monochromatic light emitting unit is arranged on the whole pixel region, and the other light emitting units of the at least two light emitting unit are arranged on the other sub-pixel regions except sub-pixels corresponding to the first monochromatic light emitting unit. With the adoption of the scheme provided by the invention, the fabrication difficulty of an OLED device is reduced, and the power consumption of the OLED display apparatus is also reduced.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED unit and a manufacturing method thereof, an OLED display panel, and an OLED display device. Background technique [0002] At present, the organic layer of an Organic Light Emitting Diode (OLED) device is generally fabricated by vacuum evaporation. For small-sized devices, the sub-pixels of R, G, and B are generally arranged in parallel, such as figure 1 shown. When making this OLED device, first use a high-precision metal mask to vapor-deposit sub-pixels of one color, and then move the high-precision metal mask to a certain position or change a high-precision metal mask to vapor-deposit another color The sub-pixels of the third color are sequentially produced to complete the production of a pixel unit. However, with the improvement of resolution, more pixel units need to be produced on a display screen of the same size, which makes the alignment of high-pr...
