However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention.

Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.
[0036] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the display panel and display device of the present invention. In the description of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
[0037] To better understand this invention, the following is combined with... Figures 1 to 5 The display panel and display device according to embodiments of the present invention will be described in detail.
[0038] Please see Figure 1 According to an embodiment of the present invention, a display panel 100 is provided, including a substrate 10, a cover plate 20, and a first support portion 30. The substrate 10 includes a substrate 11, a light-emitting layer 12, and a functional layer 13. The light-emitting layer 12 is disposed on the substrate 11, and the functional layer 13 is disposed on the side of the light-emitting layer 12 away from the substrate 11. The cover plate 20 is disposed on the side of the functional layer 13 away from the substrate 11. The first support portion 30 is disposed between the substrate 11 and the cover plate 20, and the cover plate 20 is connected to the substrate 11 through the first support portion 30. The first support portion 30, the substrate 11, and the cover plate 20 together form a sealed cavity, and the light-emitting layer 12 and the functional layer 13 are located in the sealed cavity.
[0039] In this embodiment, the display panel 100 can be a rigid screen. Optionally, the cover plate 20 can be made of glass, typically chemically strengthened glass, which covers the substrate 10 and can encapsulate and protect the entire display panel 100.
[0040] Optionally, the substrate 10 can be an OLED display. Since the display panel 100 is a rigid screen, the substrate 11 in the substrate 10 can also be a glass substrate as a support, so that the light-emitting layer 12 and the functional layer 13 are disposed on the substrate 11.
[0041] In the current technology, the encapsulation of rigid screens often involves placing a layer of rigid glass on the light-emitting layer 12. This glass can encapsulate the light-emitting layer 12, thereby isolating it from the water and oxygen environment in the external environment. The glass is then used to form a box with the bottom substrate 11, and the light-emitting layer 12 is placed in the box.
[0042] In this embodiment, the encapsulation glass increases the thickness of the entire display panel 100, which is not conducive to the overall thin and light design. Therefore, in this embodiment, the encapsulation glass is removed, and the top cover plate 20 and the bottom substrate 11 are used directly as support to form a sealed cavity, that is, a box. Thus, the glass part that is removed can reduce the thickness.
[0043] Specifically, a first support portion 30 is provided between the cover plate 20 and the substrate 11. The first support portion 30 directly connects the cover plate 20 and the substrate 11. Due to its reinforcing effect, the cover plate 20 also has the functions of support and encapsulation. The first support portion 30 supports the two and together encloses them to form a sealed cavity. The light-emitting layer 12 and the functional layer 13 are then placed in it, which can effectively isolate the film layers and play the role of encapsulation and protection.
[0044] In other words, in this embodiment, the two pieces of glass required for the box assembly are changed from the encapsulation glass and the substrate 11 to the cover plate 20 and the substrate 11. The first support part 30 directly supports the cover plate 20 and the substrate 11. The elimination of the encapsulation glass can reduce the overall thickness and achieve a thinner and lighter screen design.
[0045] This invention provides a display panel 100. A first support portion 30 is provided between a cover plate 20 at the top of the panel and a substrate 11 at the bottom of the substrate 10. The first support portion 30, the cover plate 20, and the substrate 11 together form a sealed cavity structure, essentially creating a single enclosure. This eliminates the need for a portion of the film layer originally required for enclosure between the cover plate 20 and the substrate 11, reducing the thickness of that corresponding film layer and enabling direct enclosure of the cover plate 20 and the substrate 11. This results in a reduction in the overall thickness of the display panel 100. Simultaneously, the light-emitting layer 12 and the functional layer 13 of the substrate 10 are disposed within the sealed cavity. While properly encapsulating them within the sealed cavity, the overall functionality of the display panel 100 is not lost. Ultimately, while ensuring normal display operation, the overall thickness of the module is reduced, facilitating a thinner and lighter design for the display panel 100.
[0046] As an optional embodiment, please refer to Figure 1 The functional layer 13 includes a flexible encapsulation layer 1, which is disposed on the surface of the light-emitting layer 12 away from the substrate 11.
[0047] The functional layer 13 is disposed on the light-emitting layer 12. The functional layer 13 can have different functions, thereby adjusting the light emission of the light-emitting layer 12. For example, in this embodiment, the functional layer 13 is set as a flexible encapsulation layer 1, and the flexible encapsulation layer 1 is covered on the light-emitting layer 12 to achieve the encapsulation effect.
[0048] In this embodiment, after the rigid glass encapsulation is removed, in order to ensure the encapsulation effect of the light-emitting layer 12, a flexible encapsulation layer 1 can be set on the light-emitting layer 12. The flexible encapsulation layer 1 is also applicable to the rigid screen body, thereby further improving the encapsulation effect of the light-emitting layer 12 on the basis of the cover plate 20 encapsulation. The flexible encapsulation layer 1 effectively blocks impurities such as water vapor in the external environment from entering the light-emitting layer 12.
[0049] Optionally, the light-emitting layer 12 includes a plurality of spaced light-emitting units 12a. The orthographic projection of the flexible encapsulation layer 1 on the substrate 11 covers at least a plurality of light-emitting units 12a. The flexible encapsulation layer 1 mainly encapsulates the light-emitting units 12a in the light-emitting layer 12, which can protect the electrodes and driving circuits and other components therein.
[0050] Optionally, the flexible encapsulation layer 1 includes stacked and alternately distributed inorganic and organic encapsulation layers. The inorganic encapsulation layer can be formed on the light-emitting layer 12 by chemical vapor deposition and can be made of rigid materials such as silicon nitride or silicon oxide. The organic encapsulation layer can be formed by inkjet printing to form a stacked structure with the inorganic encapsulation layer, ensuring the overall encapsulation effect of the flexible encapsulation layer 1.
[0051] Optionally, the flexible encapsulation layer 1 includes a first inorganic layer 1a, an organic layer 1b, and a second inorganic layer 1c stacked together. The first inorganic layer 1a is disposed on the surface of the light-emitting layer 12 facing away from the substrate 11, and the organic layer 1b is disposed between the first inorganic layer 1a and the second inorganic layer 1c. This embodiment uses a three-layer encapsulation as an example for illustration. The number and material of the encapsulation layers can also be adjusted according to actual encapsulation requirements, and this application is not limited in this regard.
[0052] This invention provides a display panel 100. By setting the functional layer 13 as a flexible encapsulation layer 1, the light-emitting layer 12 is encapsulated by the flexible encapsulation layer 1, which eliminates the need for rigid glass encapsulation. Together with the cover plate 20, the flexible encapsulation layer 100 performs the encapsulation function, thereby improving the encapsulation capability of the light-emitting layer 12 and achieving a better encapsulation effect. Furthermore, it forms an encapsulation protection for the light-emitting unit 12a, ensuring the safety performance of the screen.
[0053] As an optional embodiment, please refer to Figure 2 The functional layer 13 includes a touch layer 2, which is disposed on the surface of the flexible encapsulation layer 1 opposite to the light-emitting layer 12.
[0054] Optionally, the functional layer 13 also includes a touch layer 2, which is disposed on the flexible encapsulation layer 1, thereby enabling the screen to have touch functionality. The touch layer 2 is formed by patterning metal to create touch electrodes.
[0055] Optionally, the touch layer 2 is disposed on the surface of the second inorganic layer 1c facing away from the organic layer 1b. When the flexible encapsulation layer 1 forms a three-layer structure from the above-mentioned inorganic and organic components, the touch layer 2 is formed on the top surface of the second inorganic layer 1c, giving it touch functionality. This application does not impose any special limitations on the specific structure and placement of the touch layer 2.
[0056] This invention provides a display panel 100. By setting a touch layer 2 in the functional layer 13 and placing the touch layer 2 on top of the flexible encapsulation layer 1, the display panel 100 not only has better encapsulation performance but also has touch functionality.
[0057] As an optional embodiment, please refer to Figure 3 The functional layer 13 includes a polarizing layer 3, which is disposed on the surface of the touch layer 2 away from the flexible encapsulation layer 1, and is located between the touch layer 2 and the cover plate 20.
[0058] In this embodiment, in order to make the light emitted by the light-emitting layer 12 have a better display effect, a polarizing layer 3 can be set in the functional layer 13. The polarizing layer 3 is used to process the light emitted by the light-emitting layer 12, thereby improving the display effect.
[0059] Specifically, the polarizing layer 3 can be further disposed on the upper surface of the touch layer 2. At this time, the polarizing layer 3 is located between the touch layer 2 and the cover plate 20 and is located in the sealed cavity, and the polarizing layer 3 can form contact with the cover plate 20.
[0060] Optionally, the orthogonal projection of the polarizing layer 3 onto the substrate 11 covers at least a plurality of light-emitting units 12a, and the polarizing layer 3 is configured to regulate the emitted light from the light-emitting units 12a. Considering that the polarizing layer 3 mainly processes the emitted light from the light-emitting units 12a, it is necessary to ensure that the polarizing layer 3 can cover multiple light-emitting units 12a in order to simultaneously regulate the emitted light from multiple light-emitting units 12a.
[0061] Optionally, the polarizing layer 3 is deposited on the surface of the touch layer 2 away from the flexible encapsulation layer 1. In other words, in this embodiment, the polarizing layer 3 can be deposited onto the upper surface of the touch layer 2 by COE deposition process to form a polarizing film structure, thereby avoiding the need to attach a polarizing film structure on the top surface.
[0062] Therefore, it can be seen that the polarizing layer 3 formed by vapor deposition can further reduce the thickness of the film layer compared with the bonding of polarizing film, while having the same polarization effect. At the same time, the polarizing layer 3 formed by vapor deposition can also reduce the use of optical adhesive, saving the thickness of the optical adhesive, which is conducive to further thinning of the overall module thickness.
[0063] It is understandable that, in order to polarize the light emitted from the light-emitting layer 12, the polarizing layer 3 can also be placed outside the sealed cavity, that is, placed on the top surface of the cover plate 20 through a bonding process. This can also process the light emitted from the light-emitting layer 12. This application does not make any special limitation on the specific placement of the polarizing layer 3, as long as it can play a role in processing the light.
[0064] This invention provides a display panel 100, which improves the light emission effect by further setting a polarizing layer 3 on the touch layer 2 and using the characteristics of the polarizing layer 3 to process the emitted light, thereby further reducing the overall thickness of the display panel 100.
[0065] As an optional embodiment, please refer to Figure 4 and Figure 5 The substrate 10 includes a display area AA and a border area NA that is at least partially surrounding the display area AA. A first support portion 30 is disposed between the substrate 11 and the cover plate 20 at the border area NA.
[0066] Since the first support portion 30 needs to be placed between the cover plate 20 and the substrate 11, in order to avoid the first support portion 30 from obstructing the display of the substrate 10, in this embodiment the first support portion 30 is placed at the border area NA of the substrate 10, thereby reducing the overall thickness of the display panel 100 under the premise of normal display.
[0067] Optionally, the first support portion 30, projected onto the substrate 11, forms a closed annular structure and surrounds the functional layer 13. This allows the first support portion 30 to form a complete closed-loop structure, ensuring that the sealing cavity between the cover plate 20 and the substrate 11 remains sealed, thus improving the encapsulation performance of the internal light-emitting layer 12 and the functional layer 13. Simultaneously, the annular first support portion 30 is located precisely at the border area NA of the substrate 10, surrounding the display area AA, thereby avoiding any impact on the normal display of the display area AA. Furthermore, the annular first support portion 30 has a larger support area, improving the structural stability between the cover plate 20 and the substrate 11.
[0068] This application does not impose any special limitations on the specific structure and position of the first support part 30, as long as it can be stably supported between the cover plate 20 and the substrate 11 and does not obstruct the normal display of the display area AA.
[0069] This invention provides a display panel 100, in which a first support portion 30 is disposed at the border area NA of the substrate 10 to surround the display area AA, thereby avoiding any impact on the normal display of the display area AA while being stably supported between the cover plate 20 and the substrate 11, and having higher structural stability.
[0070] As an optional embodiment, please refer to Figure 4 The display panel 100 also includes a second support portion 40, which is disposed on the display area AA of the substrate 10. One end of the second support portion 40 is connected to the substrate 10 and the other end is connected to the cover plate 20.
[0071] To further improve the stability of the connection structure between the cover plate 20 and the substrate 11, a second support portion 40 is provided at the display area AA of the substrate 10 in this embodiment. That is, the first support portion 30 can be used to support the cover plate 20 and the substrate 11 at the frame area NA, while the second support portion 40 can be used to support the cover plate 20 and the substrate 11 at the display area AA. Thus, the support portion is used to support the cover plate 20 and the substrate 11 at various positions.
[0072] It should be noted that even if the second support part 40 is set at the display area AA, the second support part 40 should not block the display of the display area AA. In other words, the second support part 40 needs to be set away from the light-emitting unit 12a of the light-emitting layer 12 in order to ensure normal light emission effect.
[0073] Optionally, there are multiple second support portions 40, which are arranged at intervals to provide more stable support at the display area AA. The second support portions 40 can be columnar structures. Specifically, the second support portions 40 support the display area AA between the substrate 10 and the cover plate 20. The second support portions 40 can abut against different film layers in the substrate 10. This application does not limit this.
[0074] This invention provides a display panel 100, in which a second support portion 40 is provided at the display area AA of the substrate 10 to support the cover plate 20, thereby providing support for both the border area NA and the display area AA between the cover plate 20 and the substrate 11, increasing the contact area between the support portion and the cover plate 20, providing more stable support for the cover plate 20, and making the display panel 100 as a whole have better structural stability.
[0075] As an optional embodiment, please refer to Figure 4 The light-emitting layer 12 includes a plurality of light-emitting units 12a, a pixel limiting portion 12b and a pixel opening formed therebetween, the light-emitting units 12a being disposed in the pixel opening, and the second support portion 40 being disposed on the side of the pixel limiting portion 12b away from the substrate 11.
[0076] Since the light-emitting layer 12 of the substrate 10 has a plurality of light-emitting units 12a, and each light-emitting unit 12a is disposed in a pixel opening formed by the pixel limiting portion 12b, when the second support portion 40 is disposed at the display area AA of the substrate 10, the second support portion 40 can be disposed on the pixel limiting portion 12b, so that one end of it abuts against the pixel limiting portion 12b and the other end abuts against the cover plate 20, thereby completing the supporting function of the second support portion 40 at the display area AA.
[0077] Optionally, the second support portion 40 can be a support pillar structure at the display area AA, or it can be an integral structure with the pixel limiting portion 12b. Specifically, it can be integrally formed by deposition and etching processes. In this case, the pixel limiting portion 12b and the second support portion 40 use the same material, but this application does not limit this.
[0078] This invention provides a display panel 100. By providing a second support portion 40 on the top surface of the pixel limiting portion 12b to abut against the cover plate 20, the second support portion 40 is positioned between the cover plate 20 and the substrate 10. At the same time, the second support portion 40 avoids the light-shielding effect of the light-emitting unit 12a. While ensuring the support strength, it has a better display effect.
[0079] As an optional embodiment, the first support portion 30 includes optical adhesive or black molten adhesive.
[0080] Optionally, the first support portion 30 can be made of optical adhesive material. In this case, the first support portion 30 can be formed between the cover plate 20 and the substrate 11 by photolithography. Alternatively, the first support portion 30 can be formed into a molten adhesive structure by hot melting, so that it adheres between the cover plate 20 and the substrate 11 to form a support. This application does not impose any special limitations on the specific forming process and material of the first support portion 30, as long as it can stably connect and support between the cover plate 20 and the substrate 11.
[0081] This invention provides a display panel 100. By setting the first support portion 30 to the structure of optical adhesive or molten adhesive, the connection strength between the cover plate 20 and the substrate 11 is ensured, and the process molding is also facilitated, ultimately ensuring the stability of the overall structure.
[0082] As an optional embodiment, the overall thickness of the display panel 100 ranges from 1.0mm to 1.5mm, wherein the thickness of the first support portion 30 ranges from 9μm to 10μm.
[0083] By eliminating the original rigid encapsulation glass and directly connecting the cover plate 20 to the substrate 11 through the first support portion 30, the overall thickness of the display panel 100 is significantly reduced, ultimately enabling the overall thickness of the display panel 100 to be between 1.0mm and 1.5mm, which also depends on the thickness of the cover plate 20.
[0084] Meanwhile, the forming size of the first support portion 30 between the cover plate 20 and the substrate 11 can be 9μm-10μm, thereby enabling the overall thickness of the display panel 100 in this embodiment to be reduced by about 0.56mm compared to the thickness of the display panel 100 in the prior art, thus achieving a thinner design for the display panel 100.
[0085] This invention provides a display panel 100. By controlling the thickness of the display panel 100 and the first support portion 30 within the aforementioned range, the display panel 100 is made thinner, making it more in line with the requirements for a thinner and lighter display panel 100 and better meeting the user's needs.
[0086] According to an embodiment of the present invention, a display device is provided, including the display panel 100 as described above.
[0087] This invention provides a display panel and a display device. By setting a first support portion between the cover plate at the top of the module and the substrate at the bottom of the substrate, the first support portion, together with the cover plate and the substrate, forms a sealed cavity structure, i.e., an integral cell. This eliminates the need for a portion of the film layer originally required for cell formation between the cover plate and the substrate, reducing the thickness of the corresponding film layer and achieving direct cell formation between the cover plate and the substrate, thus reducing the overall thickness of the display panel. Simultaneously, by placing the light-emitting layer and functional layer of the substrate within the sealed cavity, while appropriately encapsulating them using the sealed cavity, the overall functionality of the display panel is not lost. Ultimately, while ensuring normal display operation, the overall thickness of the module is reduced, facilitating the design of a thinner and lighter display panel.
[0088] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
