Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a display panel and a display device. Background Technology

[0002] Currently, flat panel displays have advantages such as high image quality, energy saving, small thickness and wide application range, and are widely used in various consumer electronic products such as mobile phones, televisions, laptops, and desktop computers.

[0003] However, the performance and manufacturing process of current display devices need to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a display panel and a display device to improve the performance of the display device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a display panel is provided, comprising a substrate, an isolation structure, a plurality of light-emitting units, and a first encapsulation layer. The isolation structure is disposed on one side of the substrate along its thickness direction and defines a plurality of isolation openings. The light-emitting units are disposed on one side of the substrate along its thickness direction, and are located on the side where the isolation structure is located, with each light-emitting unit disposed in a corresponding isolation opening. The first encapsulation layer is located on the side of the light-emitting units facing away from the substrate, and includes a plurality of encapsulation portions. The orthographic projection of each light-emitting unit on the substrate lies within the orthographic projection of the corresponding encapsulation portion on the substrate. A first direction and a second direction are parallel to the substrate, the first direction is perpendicular to the second direction, and along the first direction, the orthographic projections of every two adjacent encapsulation portions on the substrate overlap.

[0007] With the above technical solution, along the first direction, the orthographic projections of every two adjacent encapsulation portions on the substrate overlap. In this way, each encapsulation portion can overlap with the orthographic projection of at least one adjacent encapsulation portion on the substrate, which can prevent encapsulation portion breakage during the manufacturing process of the display panel and improve encapsulation reliability. Furthermore, improved encapsulation reliability can prevent damage to the light-emitting unit from subsequent etching processes, thus improving the light-emitting effect.

[0077] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0078] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This application provides a display panel 100, which can be an organic light-emitting diode (OLED) display panel 100 or a micro light-emitting diode (Micro LED / μLED) display panel 100.

[0079] The display panel 100 includes a substrate 10, which includes a display area AA and a non-display area NA, with the non-display area NA surrounding at least a portion of the display area AA.

[0080] The display panel 100 also includes a plurality of light-emitting units, which are located along the thickness direction of the substrate 10 (e.g., ...). Figure 3 On one side (in the Z direction), multiple light-emitting units can be fabricated in batches according to the process flow. For example, the multiple light-emitting units may include a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit, which can emit light of different colors. For example, the first light-emitting unit can emit red light, the second light-emitting unit can emit green light, and the third light-emitting unit can emit blue light.

[0081] It is understood that the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit are sequentially vapor-deposited and patterned. That is, when the display panel 100 provided in this application embodiment is manufactured, the first light-emitting unit can be vapor-deposited and patterned first, the second light-emitting unit can be vapor-deposited and patterned second, and the third light-emitting unit can be vapor-deposited and patterned last.

[0082] In some embodiments, the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit can be patterned using a photomask.

[0083] In some embodiments, the display panel 100 further includes a pixel defined layer (PDL) 30 and an isolation structure 40. The isolation structure 40 and the pixel defined layer 30 are disposed on the same side of the substrate 10 along the thickness direction, and the isolation structure 40 is disposed on the side of the pixel defined layer 30 facing away from the substrate 10, defining a plurality of isolation openings. The orthographic projection of the light-emitting unit onto the substrate 10 can be located within the orthographic projection of the corresponding isolation opening onto the substrate 10. Optionally, the pixel defined layer 30 and the isolation structure 40 can be located in the display area AA. It is understood that the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit can be patterned using the isolation structure 40 instead of a photomask. The pixel defined layer 30 has pixel openings located within the isolation openings.

[0084] The multiple isolation openings may include a first isolation opening 401, a second isolation opening 402 and a third isolation opening 403, with the first light-emitting unit corresponding to the first isolation opening 401, the second light-emitting unit corresponding to the second isolation opening 402 and the third light-emitting unit corresponding to the third isolation opening 403.

[0085] The display panel 100 also includes a first electrode layer, a portion of which is located between the pixel definition layer 30 and the substrate 10. The first electrode layer includes a plurality of spaced first electrodes 20, a pixel opening and an isolation opening are connected, a portion of the first electrode 20 is exposed in the pixel opening, and the light-emitting layer 50 can pass through the pixel opening and connect to the first electrode 20.

[0086] It is understood that the first electrode 20 of the light-emitting unit is located on the side of the pixel definition layer 30 facing the substrate 10. The light-emitting unit includes a light-emitting layer 50 and a second electrode 60 located on the side of the light-emitting layer 50 away from the substrate 10. The light-emitting layer 50 and the second electrode 60 of the light-emitting unit are located in the isolation opening, and the light-emitting layer 50 is located between the first electrode 20 and the second electrode 60.

[0087] Optionally, the first electrode 20 can be an anode, and the second electrode 60 can be a cathode.

[0088] It is understood that the light-emitting layer 50 of the first light-emitting unit is the first light-emitting layer 51, the light-emitting layer 50 of the second light-emitting unit is the second light-emitting layer 52, and the light-emitting layer 50 of the third light-emitting unit is the third light-emitting layer 53.

[0089] It should be noted that the composition and preparation of the isolation structure 40 are specified in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, and PCT / CN2024 / 09907. 2. Further descriptions are provided in CN117979755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, and CN117500332A for reference.

[0090] The display panel 100 further includes a first encapsulation layer 70, which is disposed on the side of the pixel definition layer 30 opposite to the substrate 10 and located on the side of the light-emitting unit opposite to the substrate 10. The first encapsulation layer 70 is adjacent to the light-emitting unit. The first encapsulation layer 70 includes a plurality of encapsulation portions, which cover corresponding isolation openings and light-emitting units. In other words, the orthographic projection of the isolation opening on the substrate 10 lies within the orthographic projection of the corresponding encapsulation portion on the substrate 10, and the orthographic projection of the light-emitting unit on the substrate 10 lies within the orthographic projection of the corresponding encapsulation portion on the substrate 10.

[0091] The multiple encapsulation portions may include a first encapsulation portion 71, a second encapsulation portion 72, and a third encapsulation portion 73. The first encapsulation portion 71 corresponds to the first light-emitting unit and is also formed by patterning. The second encapsulation portion 72 corresponds to the second light-emitting unit and is also formed by patterning. The third encapsulation portion 73 corresponds to the third light-emitting unit and is also formed by patterning. Furthermore, the fabrication order of the first encapsulation portion 71, the second encapsulation portion 72, and the third encapsulation portion 73 is consistent with the fabrication order of the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit.

[0092] Please continue reading. Figure 1 , Figure 2 and Figure 3The inventors discovered that the first encapsulation layer 70 is typically used to encapsulate the light-emitting unit after it has been formed, and the multiple encapsulation portions of the first encapsulation layer 70 can encapsulate different light-emitting units. During the manufacturing process of the display panel 100, the encapsulation portions are prone to breakage, especially the edges of the encapsulation portions, which reduces the encapsulation reliability of the first encapsulation layer 70 and affects the performance of the display panel 100 and the display device.

[0093] Please refer to the following: Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 To solve the above-mentioned technical problems, this application provides a display panel 100, in which, along a first direction (e.g., Figure 4 In the X direction), the orthographic projections of every two adjacent package portions on the substrate 10 overlap. The first direction and the second direction (e.g., the X direction) Figure 4 The Y direction in the first direction is parallel to the substrate 10, and the second direction is perpendicular to the third direction. The first direction can be parallel to the scan traces of the display panel or parallel to the data traces of the display panel.

[0094] In this way, each package can overlap with the orthographic projection of at least one adjacent package on the substrate 10, which reduces the risk of damage to the package during the fabrication of the display panel 100 and improves package reliability. Furthermore, the overlap of the orthographic projections of any two adjacent packages arranged along the first direction allows for interaction among the multiple packages arranged along the first direction, improving overall package reliability. In addition, improved package reliability avoids damage to the light-emitting unit caused by subsequent etching processes, thus improving the light-emitting effect.

[0095] Therefore, the display panel 100 provided in this application can improve the performance of the display device.

[0096] It should be noted that "adjacent to two package portions" means that there is at least a portion between the two package portions where there is no light-emitting unit. Furthermore, "package portion corresponds to light-emitting unit" means that the orthographic projection of the light-emitting unit on the substrate 10 lies within the orthographic projection of the package portion on the substrate 10.

[0097] Optionally, along the first direction, the light-emitting units covered by every two adjacent encapsulation portions emit different colors. That is, among the multiple encapsulation portions arranged along the first direction, the light-emitting units corresponding to every two adjacent encapsulation portions emit different colors.

[0098] For example, please see Figure 4 and Figure 5The first encapsulation part 71, the second encapsulation part 72, and the third encapsulation part 73 are arranged alternately along the first direction. The encapsulation parts adjacent to the first encapsulation part 71 are the second encapsulation part 72 and the third encapsulation part 73, the encapsulation parts adjacent to the second encapsulation part 72 are the first encapsulation part 71 and the third encapsulation part 73, and the encapsulation parts adjacent to the third encapsulation part 73 are the first encapsulation part 71 and the second encapsulation part 72.

[0099] For example, please see Figure 6 , Figure 7 , Figure 8 and Figure 9 Along the first direction, each first encapsulation part 71 is adjacent to two second encapsulation parts 72, each third encapsulation part 73 is adjacent to two second encapsulation parts 72, and each second encapsulation part 72 is adjacent to the first encapsulation part 71 and the second encapsulation part 72 respectively.

[0100] Please continue reading. Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, at least two adjacent package portions are spaced apart on the substrate 10 along the second direction by their orthogonal projections. This creates a gap between at least two adjacent package portions, exposing part of the isolation structure 40 and facilitating the processing of the hole area.

[0101] Please continue reading. Figure 4 and Figure 5 For example, along the second direction, the orthographic projections of every two adjacent package portions on the substrate 10 are spaced apart.

[0102] Please continue reading. Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Optionally, along the second direction, the orthographic projections of every two adjacent and covered light-emitting units with the same emitting color on the substrate 10 are spaced apart. It is understood that during the fabrication of the first encapsulation layer 70, encapsulation material is first deposited on the entire surface of the side of the light-emitting unit facing away from the substrate 10, and then the unwanted portions are removed by etching, leaving the encapsulation portion of the first encapsulation layer 70. For example, during the fabrication of the first encapsulation portion 71, the material used to form the first light-emitting unit is first deposited on the entire surface, then the material used to form the first encapsulation portion 71 is deposited on the entire surface, and then the material outside the first isolation opening 401 is etched away, thereby forming the first light-emitting unit and the first encapsulation portion 71. Therefore, in the display panel 100 of this embodiment, the orthographic projections of every two adjacent and covered light-emitting units with the same emitting color on the substrate 10 are spaced apart, facilitating the fabrication of the first encapsulation layer 70.

[0103] Optionally, the orthographic projections of every two first package portions 71 on the substrate 10 are spaced apart. Optionally, the orthographic projections of every two second package portions 72 on the substrate 10 are spaced apart. Optionally, the orthographic projections of every two third package portions 73 on the substrate 10 are spaced apart.

[0104] Please refer to the following: Figure 7 and Figure 9 In some embodiments, along the second direction, the orthographic projections of every two adjacent and covered encapsulation portions with different emitting colors overlap on the substrate 10. It is understood that among the plurality of encapsulation portions arranged along the first direction, the orthographic projections of every two adjacent encapsulation portions overlap on the substrate 10. The overlap of the orthographic projections of two adjacent and covered encapsulation portions with different emitting colors along the second direction on the substrate 10 allows the first encapsulation layer 70 of the display panel 100 to overlap entirely. That is, the orthographic projection of each encapsulation portion on the substrate 10 can directly or indirectly overlap with the orthographic projections of other encapsulation portions on the substrate 10, which is beneficial for improving encapsulation reliability.

[0105] In some embodiments, the first encapsulation layer 70 includes a plurality of encapsulation portion groups arranged along a first direction, and each encapsulation portion group includes a plurality of encapsulation portions arranged along a second direction.

[0106] In this case, the orthographic projection of one of the two adjacent packaging groups on the substrate 10 overlaps with the orthographic projection of at least one of the other packaging groups on the substrate 10.

[0107] Please see Figure 4 , Figure 6 and Figure 7 For example, the orthographic projection of one package portion in one of two adjacent package portion groups onto the substrate 10 overlaps with the orthographic projection of the other package portion onto the substrate 10.

[0113] Similarly, there is a gap between two adjacent packaging parts, which can expose part of the isolation structure 40, making it easier to process the hole area.

The packaging section of the first packaging section group 71 includes one of the first packaging section 71, the second packaging section 72, and the third packaging section 73. The packaging section of the second packaging section group 72 includes the second type of the first packaging section 71, the second packaging section 72, and the third packaging section 73. The packaging section of the third packaging section group 73 includes the third type of the first packaging section 71, the second packaging section 72, and the third packaging section 73.

The orthographic projections of two adjacent packages on the substrate 10 overlap, specifically the orthographic projections of the extensions 701 of two adjacent packages on the substrate 10.

For two adjacent package portions that have an overlapping area in their orthographic projection on the substrate 10, the orthographic projections of the overlapping portions 7011 of the extensions 701 of the two adjacent package portions on the substrate 10 coincide.

[0133] In some embodiments, along the length direction of the line connecting the centers of two adjacent isolation openings, the size of the overlapping portion of the orthographic projections of the extensions 701 of two adjacent encapsulation portions on the substrate 10 is denoted as 'a', and the value of 'a' ranges from 0.5µm to 2µm.
