[0043] The features and exemplary embodiments of various aspects of the application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented when some details in these specific details are not needed. The following description of the embodiments is only to provide a better understanding of the application by illustrating the example of the application.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0045] The inventor has found through research that the existing AMOLED module is mainly composed of a glass cover plate, an adhesive layer and a polarizer layer, a display panel 1, a module support layer, a buffer layer and other film layers. Since the glass cover plate, the adhesive layer and the polarizer layer are thick, the thickness of the module is thick. Based on the analysis of the above problems, the inventor provides a display module and a display device. The display module provided by the present application is thinner and more flexible, which is more conducive to realizing the thinness of the display device and improving the bending performance.

[0046] In order to better understand this application, Figures 1 to 11 The display module and the display device according to the embodiments of the present application are described in detail.

[0047] See also Figures 1 to 3 The embodiment of the present application provides a display module, including a display panel 1 and a functional module 2, wherein the display panel 1 includes a display area DA and a non-display area NA surrounding the display area DA, the display area DA includes sub-pixels 10 of at least three colors; the functional module 2 is arranged on the light-emitting surface side of the display panel 1, and includes a supporting layer, an optical compensation layer 23, a protective layer 24 and a light-blocking layer 25, wherein the optical compensation layer 23 is formed on the side of the supporting layer facing the light-emitting surface of the display panel 1, the optical compensation layer 23 includes a plurality of color-resistance units 230 corresponding to each sub-pixel one by one, and the orthographic projection of each color-resistance unit 230 on the display panel 1 covers the sub-pixel 10 of the corresponding color thereof, the protective layer 24 is formed on the side of the supporting layer away from the display panel 1, and the orthographic projection of the protective layer 24 on the display panel 1 covers the display area DA of the display panel 1; the light-blocking layer 25 is formed between the optical compensation layer 23 and the protective layer 24, and the orthographic projection of the light-blocking layer 25 on the display panel 1 covers the non-display area NA.

[0048] The display module provided by the present application includes a display panel 1 and a functional module 2 arranged on the light-emitting surface of the display panel 1, wherein the display panel 1 includes a display area DA and a non-display area NA, and the functional module 2 includes a supporting layer that plays a supporting role, a protective layer 24 that plays a protective role, an optical compensation layer 23 for compensating the light emitted by the display panel 1, and a light-blocking layer 25 for shielding the non-display area NA, wherein the protective layer 24 is formed on the side of the supporting layer away from the display panel 1, thereby preventing external forces from causing damage to the display panel 1, and the optical compensation layer 23 is formed on the side of the supporting layer facing the display panel 1, and is used to absorb ambient light incident into the display panel 1. The ambient light that has entered the display panel 1 is reflected to form reflected light, and the optical compensation layer 23 can also reduce the amount of reflected light entering the human eye, thereby making the display effect of the display panel 1 better. In the display module provided by the present application, by setting a thinner functional module 2, the overall thickness of the display module is reduced, which helps to achieve lightness and thinness.

[0049] In a possible implementation, Figure 2 As shown, the display panel 1 and the functional module 2 are bonded and fixed by a second bonding layer 27. The second bonding layer 27 is a transparent optical adhesive layer. The thickness of the second bonding layer 27 is 5 μm to 10 μm. Specifically, the thickness of the second bonding layer 27 can be 5 μm, 6 μm, 8 μm, 9 μm, 10 μm, etc., which is not particularly limited in this application.

[0050] In a possible implementation, Figure 3 As shown, the display panel 1 includes a substrate 11 and a red sub-pixel 101, a green sub-pixel 102 and a blue sub-pixel 103 formed on the substrate 11, and the optical compensation layer 23 includes a red color resist unit 231 corresponding to the red sub-pixel 101, a green color resist unit 232 corresponding to the green sub-pixel 102 and a blue color resist unit 233 corresponding to the blue sub-pixel 103.

[0051] In the above-mentioned embodiment, the red color resist unit 231 in the optical compensation layer 23 covers the red sub-pixel 101, the green color resist unit 232 covers the green sub-pixel 102, and the blue color resist unit 233 covers the blue sub-pixel 103, so that when the external light is incident on the display panel 1, it will be filtered by the optical compensation layer 23, and only the red light of the external light incident on the red color resist unit 231 can pass through the red color resist unit 231 to enter the display panel 1, and only the green light of the external light incident on the green color resist unit 232 can pass through the green color resist unit 232 to enter the display panel 1, among the external light directed toward the blue color-resistance unit 233, only the blue light can pass through the blue color-resistance unit 233 and enter the display panel 1, thereby reducing the external light entering the display panel 1, and most of the external light entering the display panel 1 will be lost after propagating in the display panel 1, and a small part of the external light will be reflected and emitted through the optical compensation layer 23. When emitting, each color of light can only be emitted from the color-resistance unit 230 of the same color as the light of the color, thereby reducing the external light entering the display panel 1 and reflecting into the human eye, thereby improving the display effect.

[0052] In a feasible embodiment, the thickness of the optical compensation layer 23 is 2μm to 3μm. Specifically, the thickness of the optical compensation layer 23 can be 2μm, 2.1μm, 2.5μm, 2.6μm, 2.8μm and 3μm, etc., which is not particularly limited in the present application. The optical compensation layer 23 in the present application can be formed by a vapor deposition process, and the optical material is vapor deposited onto one surface of the supporting layer to form an optical compensation layer 23. The optical compensation layer 23 has a thin thickness and a good compensation effect, which helps to reduce the thickness of the display module.

[0053] In the display module of the present application, the support layer may include a single film layer or multiple film layers. Two feasible implementations are listed below:

[0054] A feasible implementation manner is that the support layer includes a first support layer 20, the first support layer 20 includes a main body area and a thinning area, the thinning area is distributed around the main body area, the main body area and the thinning area are connected with a step difference to form a receiving groove 22, and the positive projection of the receiving groove 22 on the display panel 1 covers the non-display area NA, such as Figure 2 As shown, the opening of the receiving groove 22 is located on the side of the first supporting layer 20 facing the display panel 1, or, as shown in Figure 4 As shown, the opening of the accommodating groove 22 is located at a side of the first supporting layer 20 away from the display panel 1 , and the light blocking layer 25 is disposed in the accommodating groove 22 .

[0055] In the above embodiment, if Figure 5 and Figure 6As shown, the supporting layer includes only one first supporting layer 20, and the non-display area NA of the first supporting layer 20 is formed with a receiving groove 22 covering the non-display area NA, and the light blocking layer 25 is formed in the receiving groove 22, so that the light blocking layer 25 can be accommodated in the receiving groove 22, so that the light blocking layer 25 does not affect the overall thickness of the display module, which helps to achieve a thin and light display module.

[0056] In the above embodiment, the light blocking layer 25 supplements the step difference between the main area and the thinned area, so that the first support layer 20 is flush with the light blocking layer 25, thereby facilitating the flattening of subsequent film layers and facilitating the preparation of subsequent film layers.

[0057] In the above embodiment, the material of the first support layer 20 is colorless and transparent polyimide, or it can be one or a composite film of at least two of colorless and transparent polyethylene terephthalate (PET), cycloolefin polymer film (COP), polycarbonate film (PC), and super refractive polyester film (SRF).

[0058] In the above embodiment, the thickness of the first supporting layer 20 is 20 μm to 50 μm. Specifically, the thickness of the first supporting layer 20 can be 20 μm, 21 μm, 22 μm, 25 μm, 30 μm, 35 μm, 41 μm, 48 μm, 50 μm, etc., and the present application does not make any special limitation. The thickness of the first supporting layer 20 should not be too thin to achieve the supporting effect, nor should it be too thick, as too thick will affect the overall thickness of the display module. Selecting the first supporting layer 20 in the above thickness range can achieve the supporting effect while making the display module thin and light.

[0059] Another feasible implementation is that the support layer includes a plurality of second support layers 21 stacked together, and adjacent second support layers 21 are bonded by a transparent first adhesive layer 26. One of the second support layers 21 in the support layer is a accommodating support layer arranged on the same layer as the light-blocking layer 25. The accommodating support layer includes a main body area and a thinning area. The thinning area is distributed around the circumference of the main body area. The main body area and the thinning area are connected with a step to form an accommodating groove 22. The orthographic projection of the accommodating groove 22 on the display panel 1 covers the non-display area NA. The opening of the accommodating groove 22 is located on the side of the accommodating support layer facing the display panel 1, or the opening of the accommodating groove 22 is located on the side of the accommodating support layer away from the display panel 1, and the light-blocking layer 25 is arranged in the accommodating groove 22.

[0060] Specifically, when the support layer includes two stacked second support layers 21, in a feasible implementation manner, the accommodating support layer is located on a side of the support layer close to the display panel 1, such as Figure 7 As shown, the opening of the receiving groove 22 is located on the side of the receiving support layer facing the display panel 1, or Figure 8As shown, the opening of the accommodating groove 22 is located on the side of the accommodating support layer away from the display panel 1, and the light blocking layer 25 is arranged in the accommodating groove 22; in another feasible embodiment, the accommodating support layer is located on the side of the support layer away from the display panel 1, such as Fig. 9 As shown, the opening of the receiving groove 22 is located on the side of the receiving support layer facing the display panel 1, or Fig.10 As shown, the opening of the accommodating groove 22 is located on the side of the accommodating support layer away from the display panel 1 , and the light blocking layer 25 is disposed in the accommodating groove 22 .

[0061] In the above embodiment, the supporting layer includes a plurality of stacked second supporting layers 21, and adjacent second supporting layers 21 are bonded by a transparent first adhesive layer 26 to form a supporting layer to achieve a better supporting effect. One of the second supporting layers 21 is a containing supporting layer, and a non-display area NA of the containing supporting layer is formed with a containing groove 22 covering the non-display area NA, and a light blocking layer 25 is formed in the containing groove 22, so that the light blocking layer 25 can be contained in the containing groove 22, so that the light blocking layer 25 does not affect the overall thickness of the display module, which helps to make the display module lighter and thinner.

[0062] In the above embodiment, the light blocking layer 25 supplements the height difference between the main area and the thinned area of ​​the accommodating support layer, so that the accommodating support layer and the light blocking layer 25 are flush, thereby facilitating the flattening of subsequent film layers and facilitating the preparation of subsequent film layers.

[0063] In the above embodiment, the material of the second supporting layer 21 is colorless and transparent polyimide, or it can be one or a composite film of at least two of colorless and transparent polyethylene terephthalate (PET), cycloolefin polymer film (COP), polycarbonate film (PC), and super refractive polyester film (SRF).

[0064] In the above embodiment, the thickness of the second supporting layer 21 is 10μm to 25μm. Specifically, the thickness of the second supporting layer 21 can be 10μm, 11μm, 12μm, 15μm, 18μm, 20μm, 21μm, 24μm, 25μm, etc., and the present application does not make any special limitation. The thickness of the second supporting layer 21 should not be too thin to achieve the supporting effect, nor should it be too thick, as too thick will affect the overall thickness of the display module. Selecting the second supporting layer 21 with the above thickness range can achieve a good supporting effect after the multiple second supporting layers 21 are bonded by the first bonding layer 26, while achieving the thinness of the display module.

[0065] In the above embodiment, the first bonding layer 26 is a transparent optical adhesive layer, and the thickness of the first bonding layer 26 is 5 μm to 10 μm. Specifically, the thickness of the first bonding layer 26 can be 5 μm, 6 μm, 8 μm, 9 μm, 10 μm, etc. This application does not make any special limitations, and it is only necessary to bond and fix the adjacent second supporting layer 21.

[0066] In a feasible embodiment, the material of the protective layer 24 is acrylic acid, etc. The protective layer 24 is formed on the side of the support layer away from the display panel 1 by a coating process. The film layer is thin and light and has excellent wear resistance and scratch resistance, thereby preventing external forces from scratching the outer surface of the display module (ie, the protective layer 24), thereby avoiding affecting the clarity of the display and preventing poor visual display. The thickness of the protective layer 24 is 3μm to 5μm, specifically 3μm, 4μm or 5μm, etc., and is not particularly limited in this application.

[0067] In a possible implementation, Fig.11 As shown, the display panel 1 further includes white sub-pixels 104 , and the optical compensation layer 23 includes black color resist units 234 corresponding to the white sub-pixels 104 one by one.

[0068] In the above embodiment, the display panel 1 includes a red sub-pixel 101 , a green sub-pixel 102 , a blue sub-pixel 103 and a white sub-pixel 104 , and the white sub-pixel 104 can enhance the brightness of the display module.

[0069] In a possible implementation, Fig.11 As shown, the white sub-pixel 104 is arranged between any two of the adjacent red sub-pixel 101, green sub-pixel 102, blue sub-pixel 103 and white sub-pixel 104, and the optical compensation layer 23 includes a black color-resistance unit 234 covering the white sub-pixel 104. When external light is directed to the black color-resistance unit 234, a large amount of light will be initially absorbed, and the external light entering the display panel 1 will be further absorbed inside the display panel 1. The external light reflected by the inside of the display panel 1 will be absorbed again when it is directed to the black color-resistance unit 234 again, thereby greatly weakening the external light reflected into the human eye, reducing the visual impact of the external light on the user after reflection.

[0070] In the above embodiment, the transmittance of the black optical film layer is 20% to 80%. Specifically, the transmittance of the black optical film layer is 20%, 40%, 42%, 50%, 70%, 75% or 80%, etc., and the present application does not make any special limitation. The black optical film layer selected within the above transmittance range can effectively absorb external light and reflected light after the external light is reflected inside the display panel 1, thereby reducing the visual impact of the external light on the user after reflection. At the same time, the light emitted by the white sub-pixel can be transmitted, which helps to increase the light output intensity of the display panel and improve the display effect.

[0071] The display module provided in the present application further includes a module support layer 3 and a buffer layer 4 located on the side of the display panel 1 away from the light emitting surface, so as to support and protect the display panel 1 and prevent the display panel 1 from being damaged.

[0072] The present application also provides a display device, comprising any display module provided in the above-mentioned embodiments of the present application.

[0073] The above-mentioned display device can be a mobile terminal such as a mobile phone or a tablet computer, or a fixed terminal such as a monitor or a television, and this application does not make any special limitation.

[0074] The above are only specific implementation methods of the present application.
