[0035] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity of the present invention; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0036] The directional words appearing in the following description are all directions shown in the figures, and do not 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 clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] In order to better understand the present invention, Figures 1 to 5 The display panel and the display device according to the embodiments of the present invention are described in detail.

[0038] See also Figure 1 According to an embodiment of the present invention, a display panel 100 is proposed, 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 arranged on the substrate 11, and the functional layer 13 is arranged on the side of the light-emitting layer 12 away from the substrate 11; the cover plate 20 is arranged on the side of the functional layer 13 away from the substrate 11; the first support portion 30 is arranged 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; wherein the first support portion 30, the substrate 11 and the cover plate 20 together enclose a sealed cavity, and the light-emitting layer 12 and the functional layer 13 are located in the sealed cavity.

[0039] The display panel 100 in this embodiment may be a hard screen body. Optionally, the cover plate 20 may be made of glass, usually chemically strengthened glass, which is covered on the substrate 10 to provide packaging and protection for the display panel 100 as a whole.

[0040] Optionally, the substrate 10 may be an OLED display screen. Since the display panel 100 is a hard screen as a whole, the substrate 11 in the substrate 10 may also use a glass substrate as a support, so that the light-emitting layer 12 and the functional layer 13 are arranged on the substrate 11 .

[0041] In the current prior art, the packaging of the hard screen is often done by setting a layer of hard glass on the light-emitting layer 12. The glass can encapsulate the light-emitting layer 12, thereby isolating the water and oxygen environment in the external environment. The glass is used to form a box with the bottom substrate 11, and then the light-emitting layer 12 is set in the box.

[0042] In this embodiment, the main consideration is that the above-mentioned 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, this layer of encapsulation glass is eliminated, and the top cover plate 20 and the bottom substrate 11 are directly used as support to form a sealed cavity, that is, a box, so that the eliminated glass part can reduce part of the thickness.

[0043] Specifically, a first support portion 30 is provided between the cover plate 20 and the substrate 11, and the cover plate 20 and the substrate 11 are directly connected by the first support portion 30. Due to the reinforcement effect, the cover plate 20 also has supporting and packaging functions. The first support portion 30 is supported between the two and together encloses to form a sealed cavity, and then the light-emitting layer 12, the functional layer 13 and other film layers are arranged therein, which can effectively isolate the film layers and play a role in packaging protection.

[0044] That is to say, in this embodiment, the two pieces of glass required for the box are changed from packaging glass and substrate 11 to cover plate 20 and substrate 11, and the first support part 30 is used to directly support between the cover plate 20 and the substrate 11. The elimination of the packaging glass can reduce the overall thickness, thereby realizing a lightweight design of the screen.

[0045] The embodiment of the present invention provides a display panel 100, which is provided with a first support portion 30 between a cover plate 20 at the top of the panel and a substrate 11 at the bottom of a base plate 10, and the first support portion 30 is used to enclose the cover plate 20 and the substrate 11 together to form a sealed cavity structure, that is, an overall box, thereby eliminating part of the film layer originally required for the box between the cover plate 20 and the substrate 11, reducing the thickness of the film layer corresponding to the part, and realizing the direct boxing of the cover plate 20 and the substrate 11, so that the overall thickness of the display panel 100 can be reduced. At the same time, the light-emitting layer 12 and the functional layer 13 of the substrate 10 are arranged in the sealed cavity, and while the sealed cavity is used to properly encapsulate them, it is also ensured that the overall function of the display panel 100 is not lost. Finally, on the basis of ensuring the normal display of the display panel 100, the thickness of the entire module is reduced, which is conducive to completing the lightweight design of the display panel 100.

[0046] As an alternative embodiment, see Figure 1 The functional layer 13 includes a flexible encapsulation layer 1 , and the flexible encapsulation layer 1 is arranged on a surface of the light emitting layer 12 facing away from the substrate 11 .

[0047] The functional layer 13 is arranged on the light-emitting layer 12. The functional layer 13 can have different functions so as to adjust 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 an encapsulation effect.

[0048] In this embodiment, the main consideration is that after the hard glass packaging is cancelled, in order to ensure the packaging effect of the light-emitting layer 12, a flexible packaging layer 1 can be set on the light-emitting layer 12. The flexible packaging layer 1 is also applicable to the hard screen body, so that on the basis of the cover plate 20 packaging, the packaging effect of the light-emitting layer 12 can be further improved. The flexible packaging 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 light-emitting units 12a arranged at intervals, and the orthographic projection of the flexible encapsulation layer 1 on the substrate 11 covers at least a plurality of the light-emitting units 12a. The flexible encapsulation layer 1 mainly encapsulates the light-emitting units 12a in the light-emitting layer 12, and can protect components such as electrodes and driving circuits therein.

[0050] Optionally, the flexible encapsulation layer 1 includes an inorganic encapsulation layer and an organic encapsulation layer that are stacked and alternately distributed. The inorganic encapsulation layer can be formed on the light-emitting layer 12 by a chemical vapor deposition process, and can be made of some hard 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 to ensure 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 that are stacked, the first inorganic layer 1a is disposed on the surface of the light-emitting layer 12 that is 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 is described by taking the three-layer encapsulation as an example, and the number and material of the encapsulation layers can also be adjusted according to actual encapsulation requirements, which is not limited in this application.

[0052] An embodiment of the present invention provides a display panel 100, which eliminates the hard glass packaging by setting the functional layer 13 as a flexible packaging layer 1, and utilizes the flexible packaging layer 1 to encapsulate the light-emitting layer 12, and plays a packaging role together with the cover plate 20, thereby improving the packaging ability of the light-emitting layer 12, having a better packaging effect, and further forming packaging protection for the light-emitting unit 12a, thereby ensuring the safety performance of the screen.

[0053] As an alternative embodiment, see Figure 2 The functional layer 13 includes a touch layer 2 , and the touch layer 2 is arranged on a surface of the flexible encapsulation layer 1 facing away from the light-emitting layer 12 .

[0054] Optionally, the functional layer 13 further includes a touch layer 2 , which is disposed on the flexible packaging layer 1 , so that the screen has a touch function, and the touch layer 2 is formed by patterning metal to form touch electrodes.

[0055] Optionally, the touch layer 2 is disposed on the surface of the second inorganic layer 1c away from the organic layer 1b. When the flexible encapsulation layer 1 is formed by the above-mentioned inorganic and organic layers to form a three-layer structure, the touch layer 2 is formed on the top surface of the second inorganic layer 1c, so that it has a touch function. The present application does not specifically limit the specific structure and location of the touch layer 2.

[0056] The embodiment of the present invention provides a display panel 100. By disposing a touch layer 2 in the functional layer 13 and disposing the touch layer 2 on the flexible packaging layer 1, the display panel 100 has a touch function on the basis of having better packaging performance.

[0057] As an alternative embodiment, see Figure 3 The functional layer 13 includes a polarizing layer 3 . The polarizing layer 3 is disposed on a surface of the touch layer 2 facing away from the flexible encapsulation layer 1 . The polarizing layer 3 is located between the touch layer 2 and the cover plate 20 .

[0058] In this embodiment, in order to make the light emitted from the light emitting layer 12 have a better display effect, a polarizing layer 3 may be provided in the functional layer 13, and the polarizing layer 3 is used to process the light emitted from the light emitting layer 12, thereby improving the display effect.

[0059] Specifically, the polarizing layer 3 may be further disposed on the upper surface of the touch layer 2 . In this case, the polarizing layer 3 is located between the touch layer 2 and the cover plate 20 and in the sealed cavity. The polarizing layer 3 may be in contact with the cover plate 20 .

[0060] Optionally, the orthographic projection of the polarizing layer 3 on the substrate 11 covers at least a plurality of light-emitting units 12a, and the polarizing layer 3 is configured to adjust the emitted light of the light-emitting unit 12a. Considering that the polarizing layer 3 mainly processes the light emitted by the light-emitting unit 12a, it is necessary to ensure that the polarizing layer 3 can cover the plurality of light-emitting units 12a to simultaneously adjust the light emitted by the plurality of light-emitting units 12a.

[0061] Optionally, the polarizing layer 3 is vapor-deposited on the surface of the touch layer 2 facing away from the flexible encapsulation layer 1. That is, in this embodiment, the polarizing layer 3 can be formed on the upper surface of the touch layer 2 by COE vapor deposition process to form a polarizing film layer structure, thereby avoiding the need to attach a polarizer structure to the top surface.

[0062] It can be seen that the polarizing layer 3 formed by the vapor deposition process can further reduce the thickness of the film layer compared to the lamination of the polarizer, and has the same polarization processing effect. At the same time, the polarizing layer 3 formed by vapor deposition can also reduce the use of optical glue, saving the thickness of the optical glue, which is beneficial to further thinning the thickness of the module as a whole.

[0063] It can be understood that in order to polarize the light emitted by the light-emitting layer 12, the polarizing layer 3 can also be arranged outside the sealed cavity, that is, arranged on the top surface of the cover plate 20 through a bonding process, and the light emitted by the light-emitting layer 12 can also be processed. The present application does not make any special limitation on the specific setting position of the polarizing layer 3, and any position that can play a role in processing light is acceptable.

[0064] The embodiment of the present invention provides a display panel 100 , which further disposes a polarizing layer 3 on the touch layer 2 and processes the light by utilizing the characteristics of the polarizing layer 3 , thereby improving the light emitting effect while further reducing the overall thickness of the display panel 100 .

[0065] As an alternative embodiment, see Figure 4 and Figure 5 The substrate 10 includes a display area AA and a frame area NA at least partially surrounding the display area AA, and the first support portion 30 is disposed between the substrate 11 and the cover plate 20 at the frame area NA.

[0066] Since the first support portion 30 needs to be disposed between the cover plate 20 and the substrate 11, in order to prevent the first support portion 30 from blocking the display of the substrate 10, in this embodiment, the first support portion 30 is disposed at the frame 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 orthographic projection of the first support portion 30 on the substrate 11 is a closed ring structure and is arranged around the functional layer 13, so that the first support portion 30 can form a complete closed loop structure, ensuring that the sealed cavity between the cover plate 20 and the substrate 11 enclosed therewith is always kept airtight, thereby improving the packaging performance of the internal light-emitting layer 12 and the functional layer 13. At the same time, the first support portion 30 of the ring structure is just located at the frame area NA of the substrate 10, and is arranged around the display area AA, thereby avoiding affecting the normal display of the display area AA. In addition, the first support portion 30 of the ring structure has a larger support area, which improves the structural stability between the cover plate 20 and the substrate 11.

[0068] The present application does not impose any special limitation on the specific structure and position of the first support portion 30 , as long as it can be stably supported between the cover plate 20 and the substrate 11 without obstructing the normal display of the display area AA.

[0069] An embodiment of the present invention provides a display panel 100, which avoids affecting the normal display of the display area AA by arranging the first support portion 30 in the frame area NA of the substrate 10 to surround the display area AA, so that it can be stably supported between the cover plate 20 and the substrate 11, while having higher structural stability.

[0070] As an alternative embodiment, see Figure 4 The display panel 100 further includes a second support portion 40 , which is disposed in the display area AA of the substrate 10 , wherein 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] In order to further improve the stability of the connection structure between the cover plate 20 and the substrate 11, in the present embodiment, a second supporting portion 40 is provided at the display area AA of the substrate 10. That is to say, the first supporting portion 30 can be used to support the cover plate 20 and the substrate 11 at the frame area NA, and the second supporting portion 40 can be used to support the cover plate 20 and the substrate 11 at the display area AA, so that support is completed at each position between the cover plate 20 and the substrate 11 by the supporting portion.

[0072] It should be noted that even if the second support portion 40 is disposed at the display area AA, the second support portion 40 cannot block the display of the display area AA. That is, the second support portion 40 needs to be disposed away from the light-emitting unit 12a of the light-emitting layer 12 to ensure a normal light-emitting effect.

[0073] Optionally, the second support portion 40 has multiple second support portions 40, which are arranged at intervals with each other, so that they can be more stably supported at the display area AA position, wherein the second support portion 40 can be a columnar structure. Specifically, the second support portion 40 is supported between the substrate 10 and the cover plate 20 at the display area AA, and the second support portion 40 can abut against different film layer positions in the substrate 10, which is not limited in the present application.

[0074] An embodiment of the present 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, so that the frame area NA and the display area AA between the cover plate 20 and the substrate 11 are both supported by the support portion, thereby increasing the contact area between the support portion and the cover plate 20, forming a more stable support for the cover plate 20, and making the display panel 100 as a whole have better structural stability.

[0075] As an alternative embodiment, see Figure 4 The light-emitting layer 12 includes a plurality of light-emitting units 12a, a pixel defining portion 12b and a pixel opening enclosed therebetween. The light-emitting unit 12a is disposed in the pixel opening, and the second supporting portion 40 is disposed on a side of the pixel defining 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, each light-emitting unit 12a is disposed in a pixel opening formed by a pixel defining portion 12b, when the second supporting portion 40 is disposed at the display area AA of the substrate 10, the second supporting portion 40 can be disposed on the pixel defining portion 12b, so that one end thereof abuts against the pixel defining portion 12b and the other end abuts against the cover plate 20, thereby completing the supporting function of the second supporting portion 40 at the display area AA.

[0077] Optionally, the second support portion 40 can be a support column structure at the display area AA, or it can be an integrated structure with the pixel defining portion 12b. Specifically, it can be integrally formed through deposition and etching processes. At this time, the pixel defining portion 12b and the second support portion 40 use the same material, which is not limited in the present application.

[0078] An embodiment of the present invention provides a display panel 100, which provides a second support portion 40 on the top surface of the pixel defining portion 12b to abut against the cover plate 20, thereby embodying the function of the second support portion 40 supporting between the cover plate 20 and the substrate 10, while avoiding the shading effect of the second support portion 40 on the light-emitting unit 12a, and having a better display effect while ensuring the supporting strength.

[0079] As an optional embodiment, the first supporting portion 30 includes optical glue or black molten glue.

[0080] Optionally, the first support part 30 may be made of optical adhesive material, in which case the first support part 30 may be formed between the cover plate 20 and the substrate 11 by photolithography, or the first support part 30 may be formed into a molten colloid structure by hot melting so that it is bonded between the cover plate 20 and the substrate 11 to form support. The present application does not specifically limit the specific molding process and material of the first support part 30, as long as it can be stably connected and supported between the cover plate 20 and the substrate 11.

[0081] The embodiment of the present invention provides a display panel 100, which, by setting the first support portion 30 as a structure of optical glue or molten colloid, not only ensures the connection strength between the cover plate 20 and the substrate 11, but also facilitates process molding, and ultimately ensures the stability of the overall structure.

[0082] As an optional embodiment, the overall thickness of the display panel 100 is in the range of 1.0 mm to 1.5 mm, wherein the thickness of the first support portion 30 is in the range of 9 μm to 10 μm.

[0083] By removing the original hard 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, and ultimately the overall thickness of the display panel 100 can be between 1.0 mm and 1.5 mm, which also depends on the thickness of the cover plate 20 .

[0084] At the same time, the molding size of the first support portion 30 between the cover plate 20 and the substrate 11 can be 9μm-10μm, so that the overall thickness of the display panel 100 in this embodiment can be reduced by about 0.56mm compared with the thickness of the display panel 100 in the prior art, thereby realizing a thinning design of the display panel 100.

[0085] An embodiment of the present invention provides a display panel 100, which controls the thickness of the display panel 100 and the first support portion 30 within the above range, thereby completing the thinning design of the display panel 100, making it more in line with the requirements for the thinness of the display panel 100 and better meeting the user's usage needs.

[0086] According to an embodiment of the present invention, a display device is provided, including the display panel 100 as described above.

[0087] The embodiment of the present invention provides a display panel and a display device, by setting a first support part between the cover plate at the top of the module and the substrate at the bottom of the base plate, and using the first support part, the cover plate and the substrate to enclose together to form a sealed cavity structure, that is, an overall box, thereby eliminating part of the film layer originally required for the box between the cover plate and the substrate, reducing the thickness of the film layer corresponding to the part, and realizing direct boxing of the cover plate and the substrate, so that the overall thickness of the display panel can be thinned. At the same time, the light-emitting layer and the functional layer of the substrate are set in the sealed cavity, and while using the sealed cavity to properly encapsulate them, it also ensures that the overall function of the display panel is not lost. Finally, on the basis of ensuring the normal display of the display panel, the thickness of the entire module is thinned, which is conducive to completing the lightweight design of the display panel.

[0088] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
