[0036] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0037] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] The application of display devices has penetrated into all aspects of people's life and production, such as smartphones used in daily life, display screens used in meetings, large display screens used in concerts, etc. In order to further enrich the types of display products and meet people's growing application needs, a display panel 1 with a structure is provided. Figure 1 and 2 As shown, it includes a glass substrate 11 , an MLED light emitting layer 12 , a driving layer 13 , a first black photoresist layer 14 , a second black photoresist layer 15 , a first touch layer 16 , a second touch layer 17 and a sealing layer 18 .

[0040] The glass substrate 11 is a carrier in the display panel 1, and provides bearing support for other structural layers (e.g., the MLED light emitting layer 12, the driving layer 13, the first black photoresist layer 14, the second black photoresist layer 15, the first touch layer 16, the second touch layer 17, and the sealing layer 18, etc.). In one example, the glass substrate 11 can be an alkali-containing glass substrate 11 or an alkali-free glass substrate 11.

[0041] The MLED light-emitting layer 12 emits light under driving, which serves as the basis for display. Specifically, the MLED light-emitting layer 12 includes a plurality of pixels. For example, the pixels include red sub-pixels, green sub-pixels, and blue sub-pixels. The driving layer 13 is used to drive the MLED light-emitting layer 12 to emit light, and the driving layer 13 includes at least a TFT (Thin Film Transistor) matrix. The black photoresist layer is used to block part or all of the light emitted by the MLED light-emitting layer 12. For example, the black photoresist layer is made of a black resin material. The touch layer is used to realize the touch function. For example, the touch layer can be divided into an external touch and an integrated touch. The external touch is set on the outer surface of the display panel 1. For example, infrared touch is a kind of external touch, that is, an infrared detection network is formed on the surface of the display panel 1, and the touch operation is realized by changing the infrared on the contact. For another example, capacitive touch is a kind of external touch, that is, a transparent thin film conductor layer is plated on the surface of the display panel 1, and the touch operation is realized by changing the capacitance of the contact. The sealant layer 18 plays a physical protective role. For example, the sealant layer 18 can be made of Frit (glass powder) material. Integrated touch means that the touch layer and the drive layer 13 are simultaneously prepared on the glass substrate 11 through the panel process and integrated into a structural layer, that is, the integrated structural layer includes both touch function and drive function.

[0042] The structure of the display panel 1 of this embodiment is as follows: the first black photoresist layer 14, the driving layer 13, the MLED light-emitting layer 12, the sealing layer 18 and the second black photoresist layer 15 are sequentially stacked and formed on the first end surface of the glass substrate 11. In other words, the first black photoresist layer 14 is formed on the first end surface of the glass substrate 11, the driving layer 13 is formed on the first black photoresist layer 14, the MLED light-emitting layer 12 is formed on the driving layer 13, the sealing layer 18 is formed on the MLED light-emitting layer 12, and the second black photoresist layer 15 is formed on the sealing layer 18. Then, the second touch layer 17 is formed on the second end surface of the glass substrate 11.

[0043] In order to realize double-sided display through a layer of MLED light-emitting layer 12, the first black photoresist layer 14 is a black photoresist layer with a corresponding hollow structure, which is used to shield the light of the first part of the pixels on the MLED light-emitting layer 12, and let the light emitted by the second part of the pixels on the MLED light-emitting layer 12 pass through when emitting light, so as to form the first display surface of the display panel 1. It should be noted that in order to ensure the display effect, the first part of the pixels and the second part of the pixels are evenly distributed, for example, in each row of pixels, the first part of the pixels and the second part of the pixels are alternately arranged in sequence, and in each column of pixels, the first part of the pixels and the second part of the pixels are alternately arranged in sequence. In one example, the number of pixels in the first part of the pixels is equal to the number of pixels in the second part of the pixels. A second touch layer 17 is formed on the second end of the glass substrate 11, and the second touch layer 17 is used to realize the touch operation on the first display surface. In one example, the second touch layer is attached to the second end surface of the glass substrate to realize that the second touch layer is formed on the second end surface of the glass substrate. In this example, the second touch layer 17 is an external touch layer, for example, the second touch layer 17 is an infrared touch layer or a capacitive touch layer. In another example, the second touch layer is integrated on the second end surface of the glass substrate, so that the second touch layer is formed on the second end surface of the glass substrate. In this example, the second touch layer is an integrated touch layer.

[0044] Similarly, the second black photoresist layer 15 is a black photoresist layer with a corresponding hollow structure, which is used to shield the light of the second part of the pixels on the MLED light-emitting layer 12, and allow the light emitted by the first part of the pixels on the MLED light-emitting layer 12 to pass through when emitting light, so as to form a second display surface of the display panel 1; a second touch layer 17 is formed on the second end of the glass substrate 11, and the first touch layer 16 is used to implement a touch operation on the second display surface. In one example, as Figure 1 As shown, the first touch layer 16 is an external touch layer. In this example, the first touch layer 16 is formed on the second black photoresist layer 15. The external touch layer is an infrared touch layer or a capacitive touch layer. In another example, Figure 2 As shown, the first touch layer 16 is an integrated touch layer. In this example, the first touch layer 16 is integrated on the driving layer 13 .

[0045] The display panel 1 of each of the above-mentioned embodiments has a first black photoresist layer 14, a driving layer 13, an MLED light-emitting layer 12, a sealing layer 18, and a second black photoresist layer 15 stacked in sequence on the first end surface of the glass substrate 11, and a second touch layer 17 is formed on the second end surface of the glass substrate 11. The first black photoresist layer 14 shields the light emitted by the first part of the pixels on the MLED light-emitting layer 12 when emitting light, and allows the light emitted by the second part of the pixels when emitting light to pass through, so as to form the first display surface of the display panel 1, and the touch operation on the first display surface is realized through the second touch layer 17. The second black photoresist layer 15 shields the light emitted by the second part of the pixels on the MLED light-emitting layer 12 when emitting light, and allows the light emitted by the first part of the pixels when emitting light to pass through, so as to form the second display surface of the display panel 1, and the touch operation on the second display surface is realized through the first touch layer 16, thereby providing a display panel 1 capable of double-sided display and double-sided touch. In addition, the display panel 1 of the present application adopts the MLED light-emitting layer to reduce the thickness of the display panel 1.

[0046] Based on the same inventive concept of the above embodiments, another display panel 1 is provided. Figure 3 and 4 As shown, it includes a glass substrate 11, a first MLED light-emitting layer 121, a second MLED light-emitting layer 122, a first driving layer 131, a second driving layer 132, a first black photoresist layer 14, a second black photoresist layer 15, a first touch layer 16, a second touch layer 17, a first sealing layer 181 and a second sealing layer 182.

[0047] The glass substrate 11 is a support carrier in the display panel 1, and provides bearing support for other structural layers (for example, the first MLED light-emitting layer 121, the second MLED light-emitting layer 122, the first driving layer 131, the second driving layer 132, the first black photoresist layer 14, the second black photoresist layer 15, the first touch layer 16, the second touch layer 17, the first sealing layer 181 and the second sealing layer 182, etc.). In one example, the glass substrate 11 can be an alkali-containing glass substrate 11 or an alkali-free glass substrate 11.

[0048] The MLED light-emitting layer is driven to emit light, which serves as the basis for display. The MLED light-emitting layer includes a plurality of pixels arranged according to certain regulations. For example, the pixels include red sub-pixels, green sub-pixels, blue sub-pixels, and white sub-pixels. The driving layer is used to drive the MLED light-emitting layer to emit light. The driving layer includes at least a TFT (Thin Film Transistor) matrix. For example, the driving layer can also inherit the touch function. The black photoresist layer is used to block part or all of the light emitted by the MLED light-emitting layer. For example, the black photoresist layer is made of chromium or black resin material. The touch layer is used to realize the touch function. For example, the touch layer can be divided into an external touch and an integrated touch. Among them, the external touch is set on the outer surface of the display panel 1. For example, infrared touch is a kind of external touch, that is, an infrared detection network is formed on the surface of the display panel 1, and the touch operation is realized by changing the infrared on the contact. For another example, capacitive touch is a kind of external touch, that is, a transparent thin film conductor layer is plated on the surface of the display panel 1, and the touch operation is realized by changing the capacitance of the contact. The sealant layer 18 plays a role in physical protection. Integrated touch control means that the touch layer and the drive layer are simultaneously prepared on the glass substrate 11 through a panel process and integrated into a structural layer, that is, the integrated structural layer includes both touch function and drive function.

[0049] The structure of the display panel 1 of this embodiment is as follows: the first black photoresist layer 14, the first driving layer 131, the first MLED light-emitting layer 121 and the first sealing layer 181 are sequentially stacked and formed on the first end surface of the glass substrate 11 to form the first display surface of the display panel 1. In other words, the first black photoresist layer 14 is formed on the first end surface of the glass substrate 11, the first driving layer 131 is formed on the first black photoresist layer 14, the first MLED light-emitting layer 121 is formed on the first driving layer 131, and the first sealing layer 181 is formed on the first MLED light-emitting layer 121.

[0050] The second black photoresist layer 15, the second driving layer 132, the second MLED light emitting layer 122, the second sealing layer 182 and the second touch layer 17 are sequentially stacked on the second end surface of the glass substrate 11 to form the second display surface of the display panel 1. In other words, the second black photoresist layer 15 is formed on the second end surface of the glass substrate 11, the second driving layer 132 is formed on the second black photoresist layer 15, the second MLED light emitting layer 122 is formed on the second driving layer 132, and the second sealing layer 182 is formed on the second MLED light emitting layer 122.

[0051] The display panel 1 in this embodiment is formed by two MLED light-emitting layers to form a first display surface and a second display surface of the display panel 1. The first touch layer 16 is used to implement a touch operation on the first display surface. Figure 3As shown, the first touch layer 16 is an external touch layer. In this example, the first touch layer 16 is formed on the first sealing layer 181. The external touch layer can be an infrared touch layer or a capacitive touch layer. Figure 4 As shown, the first touch layer 16 is an integrated touch layer. In this example, the first touch layer 16 is integrated on the first drive layer 131. The second touch layer 17 is used to implement touch operation on the second display surface. Figure 3 As shown, the second touch layer 17 is an external touch layer. In this example, the second touch layer 17 is formed on the second sealing layer 182. The external touch layer can be an infrared touch layer or a capacitive touch layer. Figure 4 As shown, the second touch layer 17 is an integrated touch layer. In this example, the second touch layer 17 is integrated on the second driving layer 132 .

[0052] The display panel 1 of the above embodiment includes a first black photoresist layer 14, a first driving layer 131, a first MLED light-emitting layer 121 and a first sealing layer 181 which are sequentially stacked on the first end surface of the glass substrate 11 to form the first display surface of the display panel 1. A second black photoresist layer 15, a second driving layer 132, a second MLED light-emitting layer 122, a second sealing layer 182 and a second touch layer 17 are sequentially stacked on the second end surface of the glass substrate 11 to form the second display surface of the display panel 1. The touch operation on the first display surface is realized by the first touch layer 16; the touch operation on the second display surface is realized by the second touch layer 17, thereby providing a display panel capable of double-sided display and double-sided touch. In addition, the display panel of the present application uses an MLED light-emitting layer to reduce the thickness of the display panel.

[0053] The display panel 1 in the above embodiment is applied to a product to provide a display device, including a controller and the display panel 1 as described above; the controller is connected to the first touch layer 16 and the second touch layer 17 of the display panel 1 .

[0054] It should be noted that the display panel 1 in this embodiment is the same as the display panel 1 in each embodiment of the display panel 1 of the present application. For details, please refer to the various embodiments of the display panel of the present application, and no further details will be given here.

[0055] In one example, the first touch layer 16 and the second touch layer 17 may share a controller. In another embodiment, the first touch layer 16 and the second touch layer 17 each use a controller, that is, the controller includes a first controller and a second controller; the first controller is connected to the first touch layer 16 of the display panel 1; and the first controller is connected to the second touch layer 17 of the display panel 1.

[0056] The display device provided in the present application has the functions of double-sided display and double-sided touch, and has a small thickness, which improves the utilization rate of space, expands the display boundary, enriches the types of display products, and improves the user's usage needs in more scenarios.

[0057] The display panel 1 in the above embodiment is applied to a product, such as Figure 5 As shown, a display splicing wall 2 is provided, comprising a plurality of display panels 1 as described above.

[0058] It should be noted that the display panel 1 in this embodiment is the same as the display panel 1 in each embodiment of the display panel 1 of the present application. For details, please refer to the various embodiments of the display panel of the present application, and no further details will be given here.

[0059] The display panels 1 are spliced ​​together according to a preset display shape. For example, the preset display shape is a rectangle, a square, a cylinder, and the like. After splicing and forming, the splicing wall 2 has the functions of double-sided display and double-sided touch. Among them, the first touch layers 16 of the display panels 1 in the splicing wall 2 are on the same side, and the first touch layers 16 of the display panels 1 can be independent of each other, that is, the touch functions of the display surfaces corresponding to the first touch layers 16 of the display panels 1 are opposite. In addition, the touch function of each display panel 1 can also be shared, that is, the first touch layers 16 of each display panel 1 are integrated into a whole, which is equivalent to covering one side of the display surface of the entire splicing wall 2 with a whole touch layer, and the display surface of the splicing wall 2 shares the touch function.

[0060] Similarly, the second touch layers 17 of the display panels 1 in the splicing wall 2 are on the same side, and the second touch layers 17 of the display panels 1 can be independent of each other, that is, the touch functions of the display surfaces corresponding to the second touch layers 17 of the display panels 1 are opposite. In addition, the touch functions of the display panels 1 can also be shared, that is, the second touch layers 17 of the display panels 1 are integrated into a whole, which is equivalent to covering the other side of the display surface of the splicing wall 2 with a whole touch layer, and the display surface of the splicing wall 2 shares the touch function.

[0061] The display splicing wall 2 provided in the present application has the functions of double-sided display and double-sided touch, and has a small thickness, which improves the utilization rate of space, expands the display boundary, enriches the types of display products, and improves the user's usage needs in more scenarios.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
