Abstract

The invention provides an OLED display panel and a display device. The OLED display panel comprises a substrate layer and a display base material layer which are stacked, wherein the display base material layer comprises a switching device layer, an organic light-emitting device layer, a packaging layer and a color film layer which are stacked; a waveguide film locking layer is also arranged between the organic light-emitting device layer and the color film layer; the waveguide film locking layer comprises an inner reflection film layer, and at least one first refraction film layer is arrangedat the side, close to the color film layer, of the inner reflection film layer; at least one second refraction film layer is arranged at the side, close to the organic light-emitting device layer, ofthe inner reflection film layer. The refractive index of the first refraction film layer and the refractive index of the second refraction film layer are both lower than the refractive index of the inner reflection film layer. The waveguide film locking layer changes the propagation direction of lateral light and limits the propagation direction in the inner reflecting film layer by utilizing thetotal reflection principle from light density to light sparseness, and lateral light emission is effectively controlled, so that optical crosstalk among different pixels is solved, the problems of poor viewing angle and color separation are avoided, and the display effect is improved.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular, the present application relates to an OLED display panel and a display device. Background technique [0002] At present, with the rapid development of mobile Internet technology, OLED (Organic Light Emitting Diode, organic electroluminescent diode) display panel has been applied to mobile phones and has been rapidly popularized, and has gradually become popular in the TV industry. [0003] For OLED display panels, in order to ensure a sufficiently large aperture ratio, a top emission structure is usually used. On the TFE (Thin-Film Encapsulation, thin-film encapsulation) top-emitting OLED device, directly form the COE (CF on EL, color filter on the electroluminescent layer) structure of the CF (ColorFilter, color filter) pattern by photolithography It can be applied to flexible OLED products, which can reduce the total thickness of the Panel, thereby improving...
