[0059] This disclosure will now be described in more detail with reference to the following embodiments. It should be noted that the following description of some embodiments presented herein is for illustrative and descriptive purposes only. It is not exhaustive or limited to the precise forms disclosed.

[0060] Figure 1 This is a schematic diagram showing the structure of the array substrate. (Refer to...) Figure 1 In some embodiments, the array substrate includes a planarization layer PLN, an anode layer ADL on the planarization layer PLN, a pixel defining layer PDL on the side of the anode layer ADL away from the planarization layer PLN, an emissive layer EML on the side of the anode layer ADL away from the planarization layer PLN, an encapsulation layer EN on the side of the emissive layer EML away from the planarization layer PLN, an insulating layer IN on the side of the encapsulation layer EN away from the planarization layer PLN, a touch electrode layer TEL on the side of the insulating layer IN away from the planarization layer PLN, a first coating layer OC1 on the side of the touch electrode layer TEL away from the planarization layer PLN, a color filter CF on the side of the touch electrode layer TEL away from the planarization layer PLN, a black matrix BM on the side of the first coating layer OC1 away from the planarization layer PLN, and a second coating layer OC2 on the side of the color filter CF away from the planarization layer PLN.

[0061] Optionally, the encapsulation layer EN includes an inorganic encapsulation sublayer CTD located on the side of the light-emitting layer EML away from the planarization layer PLN, and an organic encapsulation sublayer TFE located on the side of the inorganic encapsulation sublayer CTD away from the planarization layer PLN.

[0062] Optionally, the color filter CF includes multiple color filter blocks CFB.

[0063] Optionally, the light-emitting layer EML includes multiple light-emitting blocks EMB.

[0064] Optionally, the first coating layer OC1 is made of an organic insulating material. Optionally, the second coating layer OC2 is made of an organic insulating material.

[0065] In some embodiments, the array substrate includes a plurality of light-transmitting regions LTRs spaced apart from each other by non-light-transmitting regions LNTRs. In some embodiments, each of the plurality of light-emitting blocks is at least partially located in a corresponding light-transmitting region of the plurality of light-transmitting regions LTRs. In some embodiments, each of the plurality of color filter blocks CFBs is at least partially located in a corresponding light-transmitting region of the plurality of light-transmitting regions LTRs.

[0066] In some embodiments, the black matrix BM is at least partially located in the non-transparent region LNTR. In some embodiments, the pixel defining layer PDL is at least partially located in the non-transparent region LNTR. In some embodiments, the first coating layer OC1 is at least partially located in the non-transparent region LNTR.

[0067] The inventors of this disclosure discovered that, due to total internal reflection between the high-refractive-index color filter and the low-refractive-index first coating layer, Figure 1 The array substrate depicted in the present disclosure exhibits improved light extraction efficiency at the normal viewing angle. However, the inventors of this disclosure have discovered that the array substrate is prone to black spot defects. Figure 2 Shown in Figure 1 The black spot defects observed in the array substrate depicted in this disclosure. The inventors of this disclosure discovered that this is because... Figure 1 In the array substrate depicted, the color filter CF is in direct contact with the insulating layer IN. The color filter CF is made of organic material, while the insulating layer IN is made of inorganic material. Poor adhesion between the color filter CF and the insulating layer IN can lead to the peeling of the color filter CF and moisture penetration, which can damage the integrity of the array substrate, resulting in visual defects such as black spots and ultimately display failure.

[0068] Therefore, this disclosure particularly provides an array substrate and a display device that substantially eliminates one or more problems caused by the limitations and disadvantages of the prior art. In one aspect, this disclosure provides an array substrate. In some embodiments, the array substrate includes: a planarization layer; a pixel defining layer located on the planarization layer; a light-emitting layer located on the side of the pixel defining layer away from the planarization layer; an insulating layer located on the side of the light-emitting layer away from the planarization layer; an organic material layer located on the side of the insulating layer away from the planarization layer; and a color filter located on the side of the organic material layer away from the planarization layer. Optionally, the organic material layer is in direct contact with the color filter.

Figure 3 In some embodiments, the array substrate includes a planarization layer PLN, an anode layer ADL on the planarization layer PLN, a pixel defining layer PDL on the side of the anode layer ADL away from the planarization layer PLN, an emissive layer EML on the side of the anode layer ADL away from the planarization layer PLN, an encapsulation layer EN on the side of the emissive layer EML away from the planarization layer PLN, an insulating layer IN on the side of the encapsulation layer EN away from the planarization layer PLN, a touch electrode layer TEL on the side of the insulating layer IN away from the planarization layer PLN, a first coating layer OC1 on the side of the touch electrode layer TEL away from the planarization layer PLN, an organic material layer OML on the side of the insulating layer IN away from the planarization layer PLN, a color filter CF on the side of the organic material layer OML away from the planarization layer PLN, a black matrix BM on the side of the first coating layer OC1 away from the planarization layer PLN, and a second coating layer OC2 on the side of the color filter CF away from the planarization layer PLN.

[0075] In some embodiments, the black matrix BM is at least partially located in the non-transparent region LNTR. In some embodiments, the pixel defining layer PDL is at least partially located in the non-transparent region LNTR. In some embodiments, the first coating layer OC1 is at least partially located in the non-transparent region LNTR.

[0076] In some embodiments, the organic material layer OML is in direct contact with the color filter CF and with the insulating layer IN.

[0077] In some embodiments, the orthographic projection of the organic material layer OML on the substrate at least partially overlaps with the orthographic projection of the color filter CF on the substrate.

[0078] The inventors of this disclosure have discovered that an organic material layer (OML) is used as an interlayer to improve adhesion between the color filter (CF) and the insulating layer (IN). This enhanced adhesion reduces the risk of peeling or delamination during reliability testing. The close association of the organic material layer (OML) with the color filter (CF) and the presence of the organic material layer (OML) in multiple light-transmitting areas (LTR) can help reduce unwanted reflections or improve the efficiency of light passing through the color filter (CF).

[0079] In some embodiments, the difference between the refractive index of the organic material layer OML and the refractive index of the color filter CF is within 10% of the refractive index of the color filter CF (e.g., 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%). In one example, the refractive index of the organic material layer OML is in the range of 1.65 to 1.70.

In some embodiments, the refractive index of the first coating layer OC1 is less than the refractive index of the organic material layer OML and less than the refractive index of the color filter CF. In one example, the refractive index of the first coating layer OC1 is in the range of 1.45 to 1.50. In another example, the refractive index of the second coating layer OC2 is in the range of 1.45 to 1.50.

[0080] In one particular example, the organic material layer (OML) comprises organic resin material.

[0081] In some embodiments, the organic material layer OML includes a plurality of organic material blocks OMB. In some embodiments, each organic material block in the plurality of organic material blocks OMB is at least partially located in a corresponding light-transmitting region of a plurality of light-transmitting regions LTR, and at least partially located outside the non-light-transmitting region LNTR.

[0082] In some embodiments, in the non-transparent region LNTR, the array substrate includes a stacked structure comprising a first coating layer OC1, a black matrix BM on the first coating layer OC1, a portion of a color filter CF on the side of the black matrix BM away from the first coating layer OC1, and a second coating layer OC2 on the side of the portion of the color filter CF away from the black matrix BM, arranged sequentially.

[0083] Figure 4This is a plan view of the pixel defining layer, the first coating layer, and corresponding organic material blocks among a plurality of organic material blocks according to some embodiments of this disclosure. (Refer to...) Figure 3 and Figure 4 Regarding each of the multiple light-transmitting regions LTR, the first edge E1 of the orthographic projection of each organic material block in the multiple organic material blocks OMB on the substrate is spaced apart by a first minimum distance d1 from the second edge E2 of the orthographic projection of the pixel defining layer PDL on the substrate, wherein the second edge E2 surrounds at least a portion of the orthographic projection of the corresponding organic material block on the substrate; the second edge E2 is spaced apart by a second minimum distance d2 from the third edge E3 of the orthographic projection of the first coating layer OC1 on the substrate, wherein the third edge E3 surrounds at least a portion of the orthographic projection of the corresponding organic material block on the substrate; and the first edge E1 and the third edge E3 are spaced apart by a third minimum distance d3. Optionally, the first minimum distance d1 ≥ 0, the second minimum distance d2 ≥ 0, and the third minimum distance d3 ≥ 0.

[0084] In one example, the first shortest distance d1 is in the range of 0 to 6 μm. In another example, the second shortest distance d2 is in the range of 0 to 3 μm.

[0085] In one example, the thickness of the organic material layer OML ranges from 0.5 to 1.5 μm.

[0086] In one example, the thickness of the first coating layer OC1 is in the range of 1.5 to 2.5 μm. In another example, the slope angle of the first coating layer OC1 is in the range of 45 degrees to 85 degrees.

[0087] In one example, the thickness of the black matrix BM is in the range of 1 to 2 μm. In another example, the shortest distance between the edge of the black matrix BM and the top edge of the first coating layer OC1 is in the range of 0 to 4 μm.

[0088] In one example, the thickness of the color filter CF is in the range of 2 to 4 μm. In another example, the margin of overlap between the orthographic projection of each color filter block of the color filter CF onto the substrate and the orthographic projection of the first coating layer OC1 onto the substrate is in the range of 0 to 6 μm.

[0089] In one example, the thickness of the second coating layer OC2 is in the range of 3 to 6 μm.
