Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, specifically to a display panel. Background Technology
[0002] In Organic Light-Emitting Diode (OLED) display panels, polarizers are typically included, but their low light transmittance leads to poor display performance. To improve light transmittance, color filters are currently used to replace traditional polarizers. Color filters typically include light-shielding sections. The light-shielding sections on the non-display areas are usually formed across the entire surface. Because these sections are made of organic photoresist, they easily absorb moisture. Therefore, when external moisture enters the non-display areas, under high temperatures, the black matrix layer can easily peel off from other layers in the OLED display panel, creating bubbles. This allows moisture to easily penetrate from the non-display areas into the display area's film structure, causing abnormalities in the display area's film structure and resulting in poor OLED display performance.

The color filter layer 500 includes a light-shielding portion 510, a blocking portion 520, and a color resist portion 530. The light-shielding portion 510 includes a first opening 512 disposed in the display area 11 and corresponding to the light-emitting pixels, and a second opening 511 disposed in the non-display area 12; the color resist portion 530 is disposed at least at the first opening 512, and the blocking portion 520 is disposed at least at the second opening 511. Specifically, the color filter layer 500 includes a light-shielding portion 510, a color resist portion 530, a blocking portion 520, and a coating 540. The light-shielding portion 510 is disposed on the side of the second inorganic layer 430 away from the substrate 100. The light-shielding portion 510 is located in the display area 11 and the non-display area 12. The light-shielding portion 510 has a second opening 511 and a first opening 512. Both the second opening 511 and the first opening 512 penetrate the light-shielding portion 510 to expose the second inorganic layer 430.

The first color resist, the second color resist, and the third color resist are all disposed at intervals.

[0041] In one embodiment, the first color resist is a red color resist. The second color resist is a green color resist. The third color resist is a blue color resist. Optionally, the first color resist can also be a green color resist. The second color resist can also be a blue color resist. The third color resist can also be a red color resist. Other colors can also be used, and there are no limitations here. In this embodiment, the first color resist is a red color resist, the second color resist is a green color resist, and the third color resist is a blue color resist, as an example for explanation.
[0042] In the prior art, the light-shielding portion on one side of the non-display area is usually provided as a whole. Because the light-shielding portion is an organic photoresist, it is easy to absorb water. Therefore, when external moisture invades the non-display area, under the action of high temperature, the light-shielding portion can easily peel off from other film layers in the display panel, thereby generating bubbles. This allows moisture to easily invade the film layer structure in the display area from the non-display area, causing abnormalities in the film layer structure in the display area, resulting in poor display effect of the display panel. In this application, by opening a second opening 511 in the light-shielding portion 510 of the non-display area 12 and placing a blocking portion 520 in the second opening 511, the blocking portion 520 blocks or obstructs the light-shielding portion 510, making it a whole-surface provision. This reduces the risk of moisture invading from the side of the non-display area 12 into the display area 11, thereby ensuring the performance of the film layer structure in the display area 11 and thus ensuring the display effect of the display panel 10.
[0043] Please continue reading. Figure 1 and Figure 2 In one embodiment, the blocking portion 520 has multiple parts. Each pair of adjacent blocking portions 520 is spaced apart or in contact, so that the non-display area 12 has multiple blocking interfaces, thereby further reducing the risk of moisture intruding from the side of the non-display area 12 into the display area 11.
[0044] Please continue reading. Figure 1 and Figure 2 In one embodiment, the water vapor blocking performance of the blocking part 520 is greater than that of the light blocking part 510.
[0045] In this application, since the moisture blocking performance of the blocking part 520 is greater than that of the light blocking part 510, the risk of moisture intrusion from the non-display area 12 into the display area 11 is further reduced.
[0046] Please continue reading. Figure 1 and Figure 2 In one embodiment, the blocking portion 520 is made of the same material as the color resist portion, that is, both the blocking portion 520 and the color resist portion 530 are formed of the same material. The material of the color resist portion 530 is formed of a mixture containing phenolic resin, wherein the mixture containing phenolic resin contains pigment.
[0047] In this application, both the blocking portion 520 and the color resist portion 530 are formed using the same material, allowing them to be formed simultaneously. This simplifies the manufacturing process of the display panel 10, shortens the production cycle, and reduces costs. Simultaneously, because the mixture containing phenolic resin has a water-absorbing effect, external moisture is absorbed by the blocking portion on the non-display area 12, preventing external moisture from entering the display area 11 from the non-display area 12 and reducing the erosion of the film layer in the display area 11 by moisture.
[0048] Please continue reading. Figure 1 and Figure 2 In one embodiment, the blocking portion 520 includes at least one first portion 521. The first portion 521 is disposed in a second opening 511. The material of the first portion 521 is the same as the material of the first color resist.
[0049] In this application, a first portion 521 is provided in a second opening 511, forming a three-layer barrier interface on the non-display area 12 to block moisture. The three-layer barrier interface consists of the first portion 521 and the black portions on both sides of the first portion 521. That is, there is a "layer-by-layer barrier" between the non-display area 12 and the display area 11, thereby further reducing the risk of moisture intruding into the display area 11 from the sides of the non-display area 12. Since the material of the first portion 521 is the same as the material of the first color resist, the first portion 521 is formed simultaneously with the first color resist, thereby simplifying the manufacturing process of the display panel 10.
[0050] Please continue reading. Figure 1 and Figure 2 In one embodiment, the blocking portion 520 further includes at least one second portion 522. The second portion 522 is disposed in a second opening 511. The second portion 522 is on the same layer as the first portion 521 and is spaced apart. The material of the second portion 522 is the same as the material of the second color resist.
[0051] In this application, by providing a second portion 522 on top of the first portion 521, more barrier interfaces with different moisture-blocking properties are formed on the non-display area 12, reducing the risk of moisture intrusion from the non-display area 12 into the display area 11. This ensures the performance of the film structure within the display area 11, thereby guaranteeing the performance of the display panel 10. Since the material of the second portion 522 is the same as that of the second color resist, the second portion 522 is formed simultaneously with the second color resist, simplifying the manufacturing process of the display panel 10.
[0052] Please continue reading. Figure 1 and Figure 2 In one embodiment, the first portion 521 is located on the side of the second portion 522 away from the display area 11. The water vapor blocking performance of the first portion 521 is greater than that of the second portion 522.
[0053] In this application, because the water vapor blocking performance of the first section 521 is greater than that of the second section 522, most of the external water vapor is absorbed by the first section 521, and only a small portion of water vapor will pass through the first section 521 and approach the second section. Since the second section 522 is provided between the first section 521 and the display area 11, that small portion of water vapor can be blocked outside the display area 11, reducing the risk of water vapor intrusion into the film layer in the display area 11, thereby further ensuring the performance of the display panel 10.
[0054] Please continue reading. Figure 1 and Figure 2 In one embodiment, the blocking portion 520 further includes at least one third portion 523. The third portion 523 is disposed in a second opening 511. The third portion 523 is disposed on the same layer as the second portion 522 and the first portion 521, and is spaced apart from them. The material of the third portion 523 is the same as the material of the third color resist.
[0055] In this application, by adding a third portion 523 on top of the first portion 521 and the second portion 522, more barrier interfaces with different moisture-blocking properties are formed on the non-display area 12. This reduces the risk of moisture intrusion from the non-display area 12 into the display area 11, thereby ensuring the performance of the film structure within the display area 11 and thus guaranteeing the performance of the display panel 10. Since the material of the third portion 523 is the same as that of the third color resist, the third portion 523 and the third color resist can be formed simultaneously, simplifying the manufacturing process.
[0056] Please continue reading. Figure 1 and Figure 2 In one embodiment, the second portion 522 is located between the first portion 521 and the third portion 523. The first portion 521 is located on the side of the second portion 522 away from the display area 11. The moisture-blocking performance of the first portion 521 is greater than that of the second portion 522. The moisture-blocking performance of the second portion 522 is greater than that of the third portion 523.
[0057] In this application, the water vapor blocking performance of the first section 521 is set to be greater than that of the second section 522, and the water vapor blocking performance of the second section 522 is set to be greater than that of the third section 523. This ensures that most of the external water vapor is blocked or absorbed by the first section 521 and the second section, and only a small portion of water vapor will pass through the first section 521 and the second section and move closer to the third section. Since the third section 523 is provided between the second section 522 and the display area 11, that small portion of water vapor can be blocked outside the display area 11, reducing the risk of water vapor intrusion into the film layer in the display area 11, thereby further ensuring the performance of the display panel 10.
[0058] Please continue reading. Figure 1 and Figure 2 In one embodiment, the first portion 521 is composed of a plurality of connected first protective portions 521a. The second portion 522 is composed of a plurality of connected second protective portions 522a. The third portion 523 is composed of a plurality of connected third protective portions 523a.
[0059] In this application, the first part 521 is configured to be composed of multiple connected first protection parts 521a, the second part 522 is configured to be composed of multiple connected second protection parts 522a, and the third part 523 is configured to be composed of multiple connected third protection parts 523a, so that multiple blocking interfaces are formed in the non-display area 12, improving the performance of blocking moisture, while reducing the etching precision requirements, thereby reducing costs.
[0060] Please continue reading. Figure 1 and Figure 2 In one embodiment, non-display areas 12 are provided around the display area 11, that is, the display panel 10 has four non-display areas 12. Each non-display area 12 is provided with a light-shielding part 510 and a blocking part 520 provided in the light-shielding part 510.
[0061] In this application, by providing blocking portions 520 on the non-display areas 12 surrounding the display area 11, the blocking portions 520 can block the water vapor around the display area 11, reduce the risk of external water vapor entering the display area 11 from the non-display areas 12, ensure the performance of the film structure in the display area 11, and thus ensure the performance of the display panel 10.
[0062] It should be noted that the structures in this application can be removed as needed, such as removing the encapsulation layer 400, planarization layer 140, or interlayer dielectric layer 130, etc.
[0063] In another embodiment, the material of the blocking portion 520 includes a water-absorbing material, and the material of the blocking portion 520 is selected from at least one of silicon nitride, silicon oxide, water-based polyurethane, and aluminum polysulfate. In this application, because silicon nitride, silicon oxide, water-based polyurethane, and aluminum polysulfate are low-cost, using these materials to form the blocking portion 520 can prevent external moisture from invading into the display area 11 from the non-display area 12 side, which can further reduce the risk of moisture invading into the display area 11 from the non-display area 12, thereby further ensuring the display effect of the display panel 10.
[0064] Please see Figure 3 and Figure 4 It should be noted that the second structure differs from the first structure in that:
[0065] The first section 521 is composed of a plurality of spaced-apart first protective parts 521a. The second section 522 is composed of a plurality of spaced-apart second protective parts 522a. The third section 523 is composed of a plurality of spaced-apart third protective parts 523a. Each first protective part 521a is at least partially offset from every two adjacent second protective parts 522a. Each second protective part 522a is at least partially offset from every two adjacent third protective parts 523a, and each third protective part 523a corresponds to a first protective part 521a.
[0066] In this application, the first section 521, the second section 522, and the third section 523 are all formed by multiple spaced protective sections, and each first protective section 521a is at least partially offset from each pair of adjacent second protective sections 522a, and each second protective section 522a is at least partially offset from each pair of adjacent third protective sections 523a. At the same time, each third protective section 523a is correspondingly arranged with a first protective section 521a, so that multiple blocking interfaces for blocking water vapor are formed on the non-display area 12, which not only blocks water vapor but also reduces costs.
[0067] Please see Figure 5 and Figure 6 It should be noted that the third structure differs from the first structure in that:
[0068] The blocking portion 520 also includes at least one second portion 522, which is in contact with a first portion 521 and is disposed in the same layer in a second opening 511. The second portion 522 and the first portion 521 are made of different materials.
[0069] In this application, by having a second portion 522 in contact with a first portion 521 and disposed in the same layer in a second opening 511, the risk of external moisture intruding into the display area 11 from the side of the non-display area 12 is reduced. At the same time, the etching precision requirement of the second opening 511 is reduced, thereby reducing costs and ensuring the performance of the display panel 10.
[0070] In one embodiment, the width of a second opening with one portion is smaller than the width of a second opening with multiple portions. Specifically, when a first portion 521 or a second portion 522 is provided in a second opening 511, the second opening 511 has a first width; when a first portion 521 and a second portion 522 are provided in a second opening 511, the second opening 511 has a second width. The second width is greater than the first width. That is, the more portions are provided in a second opening 511, the wider the second opening 511 will be as the number of portions increases.
[0071] In this application, the width of a second opening with one portion is set to be smaller than the width of a second opening with multiple portions, so that external moisture needs to travel a longer path when entering the display area 11, thereby further reducing the risk of external moisture intruding from the non-display area 12 into the display area 11.
[0072] In another embodiment, the width of a second opening with one portion is equal to the width of a second opening with multiple portions. Specifically, when a first portion 521 or a second portion 522 is provided in a second opening 511, the second opening 511 has a first width; when a first portion 521 and a second portion 522 are provided in a second opening 511, the second opening 511 has a second width. The second width is equal to the first width.
[0073] In this application, the width of a second opening with one portion and the width of a second opening with multiple portions are set to be equal, so that the blocking part 520 can further reduce the risk of external moisture intruding from the non-display area 12 into the display area 11, while simplifying the process of forming the second opening 511 and shortening the production cycle.
[0074] Please continue reading. Figure 5 and Figure 6 In one embodiment, the blocking portion 520 further includes at least one third portion 523, which is in contact with a second portion 522 and a first portion 521 and is disposed in the same layer in a second opening 511. The second portion 522 is disposed between the third portion 523 and the first portion 521. The materials of the third portion 523, the second portion 522 and the first portion 521 are all different.
[0075] In this application, by setting the first part 521, the second part 522 and the third part 523 in a second opening 511, the risk of external moisture intruding from the non-display area 12 into the display area 11 can be further reduced. At the same time, the etching accuracy requirement of the second opening 511 is reduced, thereby reducing costs and ensuring the performance of the display panel 10.
[0076] In one embodiment, the width of a second opening with one portion is smaller than the width of a second opening with multiple portions. Specifically, when a first portion 521, a second portion 522, or a third portion 523 is provided in a second opening 511, the second opening 511 has a first width; when a first portion 521, a second portion 522, and a third portion 523 are provided in a second opening 511, the second opening 511 has a third width. The third width is greater than the first width. That is, the more portions are provided in a second opening 511, the wider the second opening 511 will be as the number of portions increases.
[0077] In this application, the width of a second opening with one portion is set to be smaller than the width of a second opening with multiple portions, so that external moisture needs to travel a longer path when entering the display area 11, thereby further reducing the risk of external moisture intruding from the non-display area 12 into the display area 11.
[0078] In another embodiment, the width of a second opening with one portion is equal to the width of a second opening with multiple portions. Specifically, when a first portion 521 or a second portion 522 is provided in a second opening 511, the second opening 511 has a first width; when a first portion 521, a second portion 522, and a third portion 523 are provided in a second opening 511, the second opening 511 has a third width. The third width is equal to the first width.
[0079] In this application, the width of a second opening with one portion and the width of a second opening with multiple portions are set to be equal, so that the blocking portion 520 can further reduce the risk of external moisture intruding from the non-display area 12 into the display area 11, while simplifying the process of forming the second opening 511 and shortening the production cycle.
[0080] Please see Figure 7 and Figure 8 It should be noted that the fourth structure differs from the first structure in that:
[0081] Please continue reading. Figure 7 and Figure 8 In the display area 11, the color resist portion 530 covers the light-shielding portion 510, so that two adjacent color resist portions 530 are in contact or overlap.
[0082] In this application, since the light-shielding part 510 has a high reflectivity of light, the color resist part 530 is set to cover the light-shielding part 510. This can prevent external light from shining on the light-shielding part 510, thereby reducing the reflectivity of light. At the same time, it can prevent the color resist part 530 from reacting with the light-shielding part 510 due to contact, thereby reducing the adhesion of the color resist part 530 and reducing the risk of the color resist part 530 peeling off, thus ensuring the display effect of the display panel 10.
[0083] It should be noted that the color resist portion 530 located in the display area 11 in the plan view is in contact or overlapping. The color resist portion 530 is drawn according to the area through which light from the light-emitting structure layer 200 can pass. Therefore, from the plan view, the color resist portion 530 located in the display area 11 does not appear to be in contact or overlapping, but this does not mean that they are not in contact.
[0084] The application discloses a display panel 10, which includes a display area 11 and at least one non-display area 12 disposed on one side of the display area 11. The display panel 10 includes an array substrate 100, a light-emitting structure layer 200, and a color filter layer 500. The light-emitting structure layer 200 is disposed on one side of the array substrate 100. The light-emitting structure layer 200 includes a plurality of light-emitting pixels disposed in the display area 11. The color filter layer 500 is disposed on the side of the light-emitting structure layer 200 away from the array substrate 100. The color filter layer 500 includes a light-shielding portion 510, a blocking portion 520, and a color resist portion 530. The light-shielding portion 510 includes a first opening 512 disposed in the display area 11 and corresponding to the light-emitting pixels, and a second opening 511 disposed in the non-display area 12; the color resist portion 530 is at least disposed at the first opening 512. In this application, in the non-display area 12, by providing a blocking part 520 in the light-shielding part 510, the light-shielding part 510 is not provided on the entire surface. Due to the blocking effect of the blocking part 520, water vapor can be blocked in the non-display area 12, reducing the risk of water vapor entering the display area 11 from the side of the non-display area 12. This reduces the risk of water vapor intrusion into the film layer in the display area 11, thereby ensuring the performance of the display panel 10.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
