Description

[0001] This application is a divisional application of Chinese Invention Patent Application No. 202010430749.5, entitled "Display Device, Display Panel, Display Cover and Manufacturing Method Thereof", filed on May 20, 2020. Technical Field

[0002] This disclosure relates to the field of display technology, and more specifically, to a display cover, a method for manufacturing the display cover, a display panel, and a display device. Background Technology

[0003] With the increasing demand for portable display devices, flexible display technology has become one of the most competitive display technologies. A major advantage of flexible display technology is its foldability, which allows for an increase in display area without increasing the size of the display device, making it highly portable.

[0004] Currently, foldable display products are gaining an increasingly large market share. These products rely on OLED display devices and can achieve both rollability and foldability. Foldable products require a folding radius of 3mm or even 1mm. Such folding conditions place high demands not only on the folding resistance of the light-emitting devices themselves but also on the folding performance of the display cover and other components.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] According to one aspect of this disclosure, a display cover is provided, the display cover comprising: Ultra-thin glass layer; A first thermoplastic material layer is disposed on one side of the ultrathin glass layer; A flexible polymer layer is disposed on the side of the first thermoplastic material layer opposite to the ultrathin glass layer; and A hardened layer is disposed on the side of the flexible polymer layer opposite to the first thermoplastic material layer.

[0027] This example embodiment first provides a display cover, such as Figure 1 As shown, the display cover includes: an ultra-thin glass layer 10, a first thermoplastic material layer 20, a flexible polymer layer 30, and a hardening layer 40. The first thermoplastic material layer 20 is disposed on one side of the ultra-thin glass layer 10, the flexible polymer layer 30 is disposed on the side of the first thermoplastic material layer 20 away from the ultra-thin glass layer 10, and the hardening layer 40 is disposed on the side of the flexible polymer layer 30 away from the first thermoplastic material layer 20.

[0028] The display cover plate provided in this disclosure has a flexible polymer layer 30 that is composited with an ultra-thin glass layer 10 through a first thermoplastic material layer 20, which effectively improves the pencil hardness and impact resistance of the display cover plate. In addition, traditional display covers plate will undergo permanent deformation under high temperature and high humidity conditions, making it impossible for them to return to a flat state. The structure provided in this disclosure, since the ultra-thin glass layer 10 is an inorganic material, has good resilience. Even under high temperature and high humidity conditions, the display cover plate can return to a relatively flat state, which improves the foldability, durability and reliability of the display cover plate.

[0029] Specifically, the ultrathin glass layer 10 is formed of ultrathin glass (UTG). The thickness of the ultrathin glass can be 30μm-150μm, for example, 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which are not listed here. Preferably, the thickness of the ultrathin glass is 50μm-100μm. The width and length of the ultrathin glass layer 10 are designed according to actual needs, and the thickness of the ultrathin glass layer 10 can also be less than 30μm or greater than 150μm; this disclosure does not impose any limitations on this. The ultrathin glass is formed of inorganic materials. By using ultrathin glass made of inorganic materials, the display cover can recover to a relatively flat state even under high temperature and high humidity conditions.

[0030] For example, the material of the first thermoplastic material layer 20 includes at least one selected from polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyoxymethylene (POM), polycarbonate (PC), polyamide (PA), acrylic plastics (CAEMP), thermoplastic polyimide (TPI), thermoplastic polyurethane (TPU), and thermoplastic vulcanizate (TPV). Preferably, the first thermoplastic material layer 20 is made of thermoplastic polyimide (TPI) or thermoplastic polyurethane (TPU). The first thermoplastic material layer 20 can cover microcracks on the surface of the ultra-thin glass, thereby improving the impact resistance and hardness of the display cover.

[0031] The thickness of the first thermoplastic material layer 20 can be 30μm-150μm, such as 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which will not be listed here. Preferably, the thickness of the first thermoplastic material layer 20 is 50μm-100μm. The width and length of the first thermoplastic material layer 20 are designed according to actual needs. The thickness of the first thermoplastic material layer 20 can also be less than 30μm or greater than 150μm. The width, length and thickness of the first thermoplastic material layer 20 and the ultrathin glass can be the same or different. This disclosure does not limit this. Preferably, the width and length of the first thermoplastic material layer 20 are the same as those of the ultrathin glass, that is, the first thermoplastic material layer 20 and the ultrathin glass can completely overlap in the orthographic projection of the preset reference plane. The first thermoplastic material layer 20 forms a complete cover on one side surface of the ultrathin glass layer 10, thereby completely covering the microcracks on the surface of the ultrathin glass and further improving the impact resistance and hardness of the display cover.

[0032] For example, the flexible polymer layer 30 can be formed from transparent polyimide (CPI) to create a CPI organic film layer. Alternatively, transparent polyamic acid (CPAA) can be modified using inorganic rigid powder nano-SiO2 to obtain a modified CPI organic film layer. This can improve the hardness of the flexible polymer layer 30 while maintaining its flexibility. The first thermoplastic material layer 20 has a flexible polymer thin layer above it and an ultra-thin glass below, enabling the display cover to have excellent hardness, folding performance, impact resistance, and good resilience, thus improving the reliability of the display cover.

[0033] The thickness of the flexible polymer layer 30 can be 30μm-150μm, such as 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which are not listed here. Preferably, the thickness of the first thermoplastic material layer 20 is 50μm-100μm. Of course, the thickness of the flexible polymer layer 30 can also be less than 30μm or greater than 150μm, which is not limited here. Preferably, the width and length of the flexible polymer layer 30 and the first thermoplastic material layer 20 are the same, that is, the orthographic projection of the flexible polymer layer 30 and the first thermoplastic material layer 20 on the ultrathin glass layer 10 completely overlaps. The flexible polymer layer 30 forms a complete coverage of one side surface of the first thermoplastic material layer 20, which further improves the folding performance, impact resistance and resilience of the display cover.

[0034] For example, a hardened layer 40 (HC) can be formed by coating the flexible polymer layer 30 on the side opposite to the first thermoplastic material layer 20. The substrate material for forming the hardened layer 40 is at least one of polyester resin (PET), polymethyl methacrylate (PMMA), cellulose triacetate (TAC), polycyclic olefin (COP), and polyimide (PI).

[0035] The thickness of the hardened layer 40 can be 2μm-20μm, such as 2μm, 5μm, 10μm, 13μm, 17μm, 20μm, etc., which are not listed here. Preferably, the thickness of the hardened layer 40 is 5μm-10μm; of course, the thickness of the hardened layer 40 can also be less than 2μm or greater than 20μm, which is not limited here. Preferably, the width and length of the hardened layer 40 and the flexible polymer layer 30 are the same, that is, the hardened layer 40 and the flexible polymer layer 30 completely overlap in their orthographic projection on the ultrathin glass layer 10, and the hardened layer 40 completely covers one side of the surface of the flexible polymer layer 30, further improving the folding performance, impact resistance and resilience of the display cover.

[0036] like Figure 2As shown, the display cover also includes a second thermoplastic material layer 50. The second thermoplastic material layer 50 is disposed on the side of the ultra-thin glass layer 10 opposite to the first thermoplastic material layer 20. By cooperating with the first thermoplastic material layer 20, the second thermoplastic material layer 50 forms a cover over the upper and lower sides of the ultra-thin glass, which can cover the micro-cracks on the surface of the ultra-thin glass, thereby further improving the impact resistance, resilience, and hardness of the display cover.

[0037] For example, the material of the second thermoplastic material layer 50 includes at least one selected from polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyoxymethylene (POM), polycarbonate (PC), polyamide (PA), acrylic plastics (CAEMP), thermoplastic polyimide (TPI), thermoplastic polyurethane (TPU), and thermoplastic vulcanizate (TPV). Preferably, the second thermoplastic material layer 50 is made of thermoplastic polyimide (TPI) or thermoplastic polyurethane (TPU) material.

[0038] The thickness of the second thermoplastic material layer 50 can be 30μm-150μm, such as 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which will not be listed here. Preferably, the thickness of the second thermoplastic material layer 50 is 50μm-100μm. The width and length of the second thermoplastic material layer 50 are designed according to actual needs. The size and thickness of the second thermoplastic material layer 50 can also be less than 30μm or greater than 150μm. The width, length and thickness of the second thermoplastic material layer 50 and the ultrathin glass layer 10 can be the same or different. This disclosure does not limit this. Preferably, the second thermoplastic material layer 50 has the same width and length as the ultrathin glass layer 10, meaning that the orthographic projections of the second thermoplastic material layer 50 and the ultrathin glass layer 10 on a preset reference plane completely overlap. The second thermoplastic material layer 50 completely covers the other surface of the ultrathin glass layer 10, thereby completely covering microcracks on the surface of the ultrathin glass layer 10 and further improving the impact resistance and hardness of the display cover. Furthermore, the material, thickness, length, and width of the second thermoplastic material layer 50 and the first thermoplastic material layer 20 may be the same or different, and this disclosure does not impose any limitations in this regard.

[0039] The following are embodiments of the method disclosed herein, which can be used to manufacture embodiments of the apparatus disclosed herein. For details not disclosed in the embodiments of the method disclosed herein, please refer to the embodiments of the apparatus disclosed herein.

[0040] This disclosure also provides a method for manufacturing a display cover, such as... Figure 3 As shown, the manufacturing method includes: Step S100: Provide a flexible polymer layer; Step S200: A first thermoplastic material layer is formed on one side of the flexible polymer layer; Step S300: A hardened layer is formed on the side of the flexible polymer layer opposite to the first thermoplastic material layer; Step S400: An ultrathin glass layer is formed on the side of the first thermoplastic material layer away from the flexible polymer layer.

[0041] The manufacturing method of the display cover provided in this disclosure, wherein the flexible polymer layer is composited with the ultra-thin glass layer through a first thermoplastic material layer, effectively improves the pencil hardness and impact resistance of the display cover. In addition, traditional display covers will undergo permanent deformation under high temperature and high humidity conditions, making it impossible for them to return to a flat state. The manufacturing method provided in this disclosure uses an inorganic material for the ultra-thin glass layer, which has good resilience. Even under high temperature and high humidity conditions, the display cover can return to a relatively flat state, improving the foldability, durability and reliability of the display cover.

[0042] The following will further explain each step of the manufacturing method of the cover plate in this example embodiment.

[0043] In step S100, a flexible polymer layer is provided.

[0044] Specifically, such as Figure 1 As shown, a flexible polymer layer 30 is provided. The flexible polymer layer 30 can be formed from transparent polyimide (CPI) to form a CPI organic film layer. Simultaneously, the transparent polyamic acid (CPAA) can be modified using inorganic rigid powder nano-SiO2 to obtain a modified CPI organic film layer. This can improve the hardness of the flexible polymer layer 30 while maintaining its flexibility. The thickness of the flexible polymer layer 30 can be 30μm-150μm, for example, 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which are not listed here.

[0049] Specifically, such as Figure 1 As shown, a hardened layer 40 can be formed on the side of the flexible polymer layer 30 away from the first thermoplastic material layer 20 by processes such as coating. The substrate material for forming the hardened layer 40 is at least one of polyester resin (PET), polymethyl methacrylate (PMMA), cellulose triacetate (TAC), polycyclic olefin (COP), and polyimide (PI).

[0050] The thickness of the hardened layer 40 can be 2μm-20μm, such as 2μm, 5μm, 10μm, 13μm, 17μm, 20μm, etc., which will not be listed here. Preferably, the thickness of the hardened layer 40 is 5μm-10μm. Of course, the thickness of the hardened layer 40 can also be less than 2μm or greater than 20μm, which is not limited here.

[0051] In step S400, an ultrathin glass layer is formed on the side of the first thermoplastic material layer away from the flexible polymer layer.

[0052] Specifically, such as Figure 1As shown, the ultrathin glass layer 10 is laminated to the side of the first thermoplastic material layer 20 away from the flexible polymer layer 30 by means of hot pressing or other methods. The ultrathin glass layer 10 is formed of ultrathin glass (UTG). The thickness of the ultrathin glass can be 30μm-150μm, for example, 30μm, 50μm, 70μm, 90μm, 100μm, 130μm, 150μm, etc., which are not listed here. Preferably, the thickness of the ultrathin glass is 50μm-100μm. The width and length of the ultrathin glass are designed according to actual needs, and the thickness of the ultrathin glass can also be less than 30μm or greater than 150μm; this disclosure does not impose any limitations on this. The ultrathin glass is formed of inorganic materials. By using ultrathin glass made of inorganic materials, the display cover can recover to a relatively flat state even under high temperature and high humidity conditions.

[0053] For example, in step S400, an ultrathin glass layer is formed on the side of the first thermoplastic material layer opposite to the flexible polymer layer, such as... Figure 4 As shown, it includes: Step S410: Provide an ultra-thin glass layer.

[0054] Specifically, such as Figure 2 As shown, an ultrathin glass layer 10 is provided, which is formed of ultrathin glass (UTG).

The ultrathin glass is formed of inorganic materials. By using ultrathin glass made of inorganic materials, the display cover can recover to a relatively flat state even under high temperature and high humidity conditions.

[0055] Step S420: Form a second thermoplastic material layer on one side of the ultrathin glass layer.

[0056] Specifically, such as Figure 2As shown, a second thermoplastic material layer 50 can be formed on one side of the ultrathin glass layer 10 by means of hot pressing or the like.
