Embodiment 1

[0047] figure 1 This is a structural diagram of a display panel provided by an embodiment of the present invention; please refer to figure 1 . This embodiment provides a display panel, which includes a substrate 100, a light-emitting layer 200, an encapsulation layer 300, and a light-shielding unit 420 that are stacked. The light-emitting layer 200 includes a plurality of light-emitting units 210 for emitting light of different colors. In the direction of, the projection of the partial shading unit 420 overlaps the projection of the partial light-emitting unit 210; a convex structure 500 or a concave structure (not shown in the figure), a convex structure 500 or a concave structure is provided on the light exit path of the display panel The refractive index of is greater than the refractive index of the encapsulation layer 300.

[0048] Compared with the prior art, the shading unit 420 in this embodiment can shield more incident light and absorb more reflected light, thereby impr...

Embodiment 2

[0067] Figure 4 This is a structural diagram of a display panel provided by another embodiment of the present invention; please refer to Figure 4 . On the basis of the first embodiment, in the display panel of this embodiment, the encapsulation layer 300 includes a first encapsulation film layer 310, a second encapsulation film layer 320, and a third encapsulation film layer 330 that are stacked, and the protrusion structure 500 includes The first protrusion 510 arranged on the first electrode layer and the second protrusion 520 and the third protrusion 530 arranged on both sides of the second packaging film layer 320; wherein the refractive index of the first protrusion 510 is greater than that of the first protrusion 510. The refractive index of the packaging film layer 310, the refractive index of the second protrusion 520 is greater than or equal to the refractive index of the second packaging film layer 320, and the refractive index of the third protrusion 530 is greater ...

Abstract

The invention provides a display panel and a display device. The display panel comprises a substrate, a light emitting layer, an encapsulation layer, and a light shielding unit which are stacked, wherein the light emitting layer includes a plurality of light emitting units for emitting light of different colors; in the direction perpendicular to the substrate, the projection of a portion of the light shielding unit overlaps the projection of a portion of the light emitting unit; a convex structure or concave structure is disposed on the light-emitting path of the display panel, and has a refractive index greater than the refractive index of the encapsulation layer. The display effect of the display panel is further improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is a current-injection light-emitting display device, which is composed of an anode, an organic light-emitting layer and a cathode in a sandwich structure. After being energized, the holes on the anode and the charge on the cathode combine in the organic light-emitting layer and release energy. The energy makes the organic light-emitting substance molecules in the organic light-emitting layer transition from the ground state to the excited state. The excited state is very unstable. The excited molecule returns to the ground state from the excited state, and luminescence occurs during the radiation transition. The OLED display device includes a metal layer, and the metal layer has a high reflectivity to external ambient light, and the reflected light will affect the display...
