Problems solved by technology

[0004] However, with the above solution, the incident light with the same color as the filter layer can still pass through the filter layer, so there will still be some reflected light that cannot be filtered out

Embodiment 1

[0053] figure 1 A schematic structural diagram of a display panel provided for an embodiment of the present invention; please refer to figure 1. This embodiment provides a display panel, including a laminated substrate 100, a light-emitting layer 200, an encapsulation layer 300, and a filter layer 400. The light-emitting layer 200 includes a plurality of light-emitting units 210 for emitting light of different colors, and the filter layer 400 It includes a plurality of filter units 410 that only allow light of a single color to pass through. The plurality of filter units 410 correspond to the plurality of light-emitting units 210 one-to-one, and the light-emitting color of the light-emitting unit 210 is related to the color of light that the corresponding filter unit 410 allows to pass through. The colors are the same; a light shielding unit 420 is also provided between adjacent two filter units 410, and the light shielding unit 420 includes a first light shielding portion 42...

Embodiment 2

[0066] image 3 A schematic structural diagram of a display panel provided for another embodiment of the present invention; please refer to image 3 . On the basis of the first embodiment above, in the display panel of this embodiment, the encapsulation layer 300 includes multiple encapsulation film layers stacked, and at least one encapsulation film layer is provided with a first light shielding portion 421 .

[0067] In this embodiment, the packaging film layer may be a rigid film layer, a flexible film layer, or a mixed film layer of rigid and flexible laminates.

[0068] Such as image 3 As shown, in an optional 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, wherein the first encapsulation film layer 310 and the third encapsulation film layer Layer 330 may be a flexible film layer, and second encapsulating film layer 320 may be a rigid film layer. In ...

Embodiment 3

[0074] Figure 4 A schematic structural diagram of a display panel provided for another embodiment of the present invention; please refer to Figure 4 . On the basis of the first embodiment above, in the display panel of this embodiment, the first light shielding portion 421 and the second light shielding portion 422 are integrally formed.

[0075] In this embodiment, the first light-shielding part 421 and the second light-shielding part 422 are provided as an integrated structure, which can reduce the process steps. After the encapsulation layer 300 is manufactured, it can be formed on the encapsulation layer by etching to accommodate the first light-shielding part 421. The accommodating cavity, and the first light-shielding portion 421 and the second light-shielding portion 422 are produced by one printing and coating, so that the fabrication of the light-shielding unit 420 is more convenient.

[0076] Further, in a plane parallel to the substrate 100 , the cross-sectional...

Abstract

The present invention provides a display panel and a display device. The display panel includes a stacked substrate, a light emitting layer, a packaging layer and a filter layer. The light emitting layer includes a plurality of light emitting units for emitting light of different colors. The filter layer includes a plurality of A filter unit that only allows light of a single color to pass through. Multiple filter units correspond to multiple light-emitting units, and the light-emitting color of the light-emitting unit is the same as the color that the corresponding filter unit allows to pass through the light; two adjacent A light shielding unit is further provided between the light filtering units, and the light shielding unit includes a first light shielding portion disposed inside the encapsulation layer and a second light shielding portion disposed outside the encapsulation layer. In this embodiment, the height of the light-shielding unit in the direction perpendicular to the substrate is increased, thereby further improving the absorption efficiency of reflected light and improving the display effect of the display panel.

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] An organic light-emitting diode (Organic Light-Emitting Diode; OLED) is a current-injection light-emitting display device, which consists of an anode, an organic light-emitting layer and a cathode in a sandwich structure. After electrification, the hole on the anode and the charge of the cathode combine in the organic light-emitting layer and release energy, which 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, and the excited molecules return to the ground state from the excited state, and luminescence occurs in the process of radiative transition. The OLED display device includes a metal layer (for example, the metal layer can be a cathode, or a reflective layer between t...
