The OLED device layer 20 includes a plurality of light emitting units for emitting light of different colors, and the light emitting units may specifically include an anode, a cathode, and a light emitting layer disposed between the anode and the cathode. The luminescent layer can be an organic luminescent layer or a quantum dot luminescent layer, or a combination of the organic luminescent layer and the quantum dot luminescent layer. Furthermore, at least one of a hole injection layer, a hole transport layer and an electron blocking layer can be arranged between the anode and the luminescent layer, and at least one of an electron injection layer, an electron transport layer and a hole blocking layer can be arranged between the cathode and the luminescent layer. The structure of the OLED device layer 20 is the same as that of the conventional OLED device, and thus, the description thereof is omitted.
The first inorganic layer 30 is arranged on one side of the OLED device layer 20 departing from the substrate 10, and because the first inorganic layer 30 has high compactness, water vapor and oxygen can be well isolated, and the water vapor and oxygen in the air are prevented from permeating into the OLED device layer 20, so that the water oxygen corrosion resistance of the display panel is improved. Among them, the first inorganic layer 30 may be formed of a transparent ceramic material such as SiNx, SiOx, SiOxNy, etc., and/or may be formed of a transparent metal oxide material such as Al2O3, TiO2, MgO, CrO, etc. The first inorganic layer 30 may be formed by a conventional method including, but not limited to, Ink Jet Printing (IJP), Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD), Atomic Layer Deposition (ALD), and the like, and is not limited thereto.
In the embodiment of the present application, the thickness of the first inorganic layer 30 is in the range of 0.1 to 2 μm.
With continued reference to fig. 1 to 3, the color filter layer 40 is disposed on a side of the first inorganic layer 30 facing away from the OLED device, the color filter layer 40 includes a plurality of color filter units 41 and a black matrix 42, the plurality of color filter units 41 are disposed at intervals, and the black matrix 42 is disposed between adjacent color filter units 41.

It should be noted that the black matrix 42 is also called a black color resistor, and the color filter units 41 are color resistors corresponding to colors, respectively. Color filter layer 40 may be formed by a conventional photolithography process and will not be described in detail herein.
It should be noted that the black matrix 42 can absorb the light emitted from the light emitting units of the OLED device layer 20, and prevent the light emitted from the light emitting units from traveling to the adjacent light emitting units, so as to reduce or prevent color mixing and improve the display quality.
Referring to fig. 2, exemplarily, the red filter units 411, the green filter units 412, and the blue filter units 413 are arranged in a matrix, each row of the red filter units 411, the green filter units 412, and the blue filter units 413 are sequentially arranged from left to right at intervals, each row is a filter unit of the same color, and a black matrix 42 is formed between each two rows and two columns.

Because the color filter unit 41 allows the color of the transmitted light to be consistent with the color of the light emitted by the light emitting unit, when the external environment light enters the interior of the OLED display panel, part of the external environment light is absorbed by the black matrix 42, the rest of the external environment light is filtered by the color filter unit 41 to obtain most of the light, only the rest of the light with single color can be transmitted, and part of the light entering the interior of the OLED display panel loses part of light intensity when being reflected by the interior of the display panel, and when the external environment light passes through the exit again, the reflected light passes through the reabsorption of the black matrix 42 and the refiltering of the color filter unit 41, so that the intensity of the emergent reflected light is further reduced, and the contrast of the OLED display panel and the OLED display device is ensured.
