Abstract: An organic light-emitting diode (OLED) display device and an OLED display apparatus using the same are disclosed. The OLED display device includes a plurality of pixels (16) arranged in an array on a substrate (11), a side surface of a light-emitting layer (13) of the pixels (16) being covered with a first insulating structure (14) having a refractive index less than that of the light-emitting layer (13). The OLED display device has a high light extracting rate.

Abstract: An organic electroluminescent device and a preparation method thereof, and a display device are provided. The organic electroluminescent device comprises a substrate (1), a first electrode (2) formed on the substrate (1), a light-emitting layer (3) formed on one side of the first electrode (2) away from the substrate (1), and a second electrode (4) formed on one side of the light-emitting layer (3) away from the first electrode (2), and only a portion of a projection of the light-emitting layer (3) on the substrate (1) is positioned at an overlapping portion of projections of the first electrode (2) and the second electrode (4) on the substrate (1). The organic electroluminescent device can facilitate realizing a high resolution design of a display screen.

Abstract: A method for repairing an organic light-emitting diode (OLED) display device includes: determining the position of foreign particle (13) in a lamination structure (12); removing the foreign particle (13) and layers over the foreign particle (13) and in a recess region to be formed, so as to form a recess (21) in the lamination structure (12), in which an opening of the recess (21) is towards the external environment; and forming a repair structure (31) in the recess (21), in which the refractive index of the repair structure (31) is less than that of the lamination structure (12). The method overcomes the black spot defect caused by the foreign particle, improves the product yield and avoids the waste of cost.
