Claim 0:
1. An OLED display panel, comprising:
a flat display area and an edge curved-surface display area; wherein the edge curved-surface display area is provided with an optical film layer, and the optical film layer is configured to reduce a light intensity of emergent light with a preset color in the edge curved-surface display area;
a light-emitting unit; and
an encapsulation layer,
wherein the encapsulation layer is disposed on a side of the light-emitting unit close to a light-emitting surface of the OLED display panel and the optical film layer is disposed on a side of the encapsulation layer away from the light-emitting unit, and
wherein the optical film layer comprises a reflection enhancing film; subsequent to an entrance of an incident light into the reflection enhancing film, a propagation distance d of the incident light in the reflection enhancing film satisfies a following formula: 2nd=(2k+1)λ/2, to increase a reflectivity of light with a wavelength of λ, where k=0, 1, 2 . . . , n is a refractive index of the reflection enhancing film.
