Abstract:
The present disclosure provides an OLED display panel and a method for fabricating the same and an OLED display apparatus. The OLED display panel includes a light-emitting layer, the light-emitting layer includes white sub-pixels and color sub-pixels, the size of the white sub-pixel is equal to the sum of size of at least two of the color sub-pixels, and the number of the color sub-pixels is less than the number of color-forming primary colors. The OLED display panel further includes a color film, the color film including color blocks matching the color sub-pixels, the color blocks being disposed on a side of the light-emitting layer toward the display side and at positions corresponding to the positions where the white sub-pixels are located.
