DETAILED DESCRIPTION
[0042] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.
[0043] 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 the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.
[0044] For ease of understanding, the technical terms involved in the embodiments of the present disclosure are first explained and described below.
[0045] Display panel,Display Panel.
[0046] Protective layer, including MLC (Micro-layer-Coating).
[0047] Optical adhesive, also known as OCA (Optically Clear Adhesive), is a special adhesive used to bond transparent optical components (such as display screens, lens groups, etc.). It includes organic silicone, acrylic resin, unsaturated polyester, polyurethane, epoxy resin and other adhesives.
[0048] UFG, Ultra Thin Glass, is ultra-thin flexible glass.
[0049] The support layer has the function of supporting and protecting. It is also called the PW layer, including Plastic Window and Protective Window. It includes PET material or CPI material.
[0050] AR, Anti-Ref lect ion, optical nanofilm.
[0051] In order to better understand the flexible display module of the present disclosure, an electronic device using the flexible display module is described below.
[0052] like Figure 1 and Figure 2 As shown, in some embodiments, an electronic device is provided, including a housing component, a control component and a flexible display module, wherein the flexible display module is communicatively connected with the control component and is respectively mounted on the housing component. Thus, the flexible display module is controlled by the control component to display.
[0053] The flexible display module includes a substrate, a display panel and a light-transmitting plate. The substrate includes a front side and a back side arranged opposite to the front side along the thickness direction of the substrate. The display panel includes a display body, a bending body and a binding body. The display body is arranged on the front side. The bending body is connected to the display body and the binding body respectively, so that the binding body is arranged on the back side. The bending body is provided with a protective layer, and part of the protective layer protrudes from the front side. The light-transmitting plate covers the display body, so that the display body is sandwiched between the light-transmitting plate and the substrate. The light-transmitting plate is provided with an avoidance groove for avoiding the protective layer.
[0054] During the stacking of the flexible display module, the protective layer on the bending body is avoided by avoiding the groove, so that the light-transmitting plate and the display body are more closely attached, and the thickness of the flexible display module can be reduced. The electronic device uses a flexible display module with a smaller thickness, which is conducive to achieving a lighter and thinner electronic device.
[0055] Optionally, the display panel includes an organic light emitting semiconductor (OLED). OLED is a current-type organic light emitting device, which is a phenomenon of luminescence caused by the injection and recombination of carriers, and the luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode of the OLED will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light emitting layer. When the two meet in the light emitting layer, energy excitons are generated, thereby exciting the light emitting molecules to finally produce visible light.
[0056] OLED includes AMOLED (Active-matrix organic light-emitting diode) and PMOLED (Passive-matrix organic light-emitting diode).
[0057] like Figure 2 As shown, in some embodiments, the flexible display module further includes an AR film, and the AR film covers the light-transmitting plate, so that the light-transmitting plate is sandwiched between the display body and the AR film. In this way, the surface reflection of light can be reduced.
[0058] In one embodiment, the AR film can achieve an ultra-low reflectivity effect with a reflectivity of less than 2%.
[0059] like Figure 3 As shown, in some embodiments, the light-transmitting plate includes a first body covering the display body and a second body fixedly connected to the first body along the width direction of the substrate, and an avoidance groove is provided on the second body, and a portion of the protective layer is protruding from the front and embedded in the avoidance groove to be sandwiched between the second body and the substrate. In this way, the display body is covered by the first body to achieve reflection and light transmission of the display body. By providing an avoidance groove on the second body to accommodate and avoid the protective layer, during the bending and binding process of the display panel, part of the bending body is sandwiched between the second body and the substrate, and the first body and the display body are more closely attached, effectively reducing the thickness of the flexible display module.
[0060] Alternatively, if Figure 2 as well as Figure 3 As shown, in some embodiments, the flexible display module further includes a first optical adhesive, which is sandwiched between the first body and the display body. In this way, the first body can be reliably fixed to the display body by using the first optical adhesive without affecting the light transmission effect of the display body.
[0061] like Figure 2as well as Figure 3 As shown, the thickness direction of the substrate is the Z-axis direction, and the width direction of the substrate is the X-axis direction. The thickness direction of the first optical adhesive, the thickness direction of the light-transmitting plate, and the protruding direction of the protective layer are also the Z-axis direction.
[0062] Alternatively, if Figure 3 As shown, in some embodiments, the thickness of the first optical adhesive is H1, the maximum thickness difference between the first body and the second body is H2, and the maximum height of the protective layer protruding from the front is H3. Among them, H1+H2>H3. In this way, it is ensured that the avoidance groove can accommodate the protective layer, and there is a gap between the second body and the protective layer, which will not affect the bending body, and then the second body can be used to protect the bending body, thereby improving the durability of the flexible display module.
[0063] It should be noted that “the maximum thickness difference between the first body and the second body is H2” should be understood in a broad sense, including the depth of the groove to avoid the groove.
[0064] In some embodiments, 25um≤H1≤100um, 30um≤H3≤120um. In this way, the thickness of the first body and the second body can be flexibly designed according to the protruding height of the protective layer and the thickness of the first optical adhesive to ensure that the avoidance groove can accommodate the protective layer.
[0065] Optionally, 30um≤H1≤50um, 35um≤H3≤60um.
[0066] Optionally, H1=25um, H3=30um. Alternatively, H1=30um, H3=35um. Alternatively, H1=50um, H3=60um. Alternatively, H1=100um, H3=120um.
[0067] like Figure 3 As shown, in some embodiments, along the width direction of the substrate, the minimum spacing between the protective layer and the first body is L1, 0.05mm≤L1≤0.15mm. In this way, it is ensured that the avoidance groove can accommodate the protective layer, and there is a gap between the first body and the protective layer, which will not affect the bending body, and the second body can be used to protect the bending body, thereby improving the durability of the flexible display module. Compared with traditional technology, L1 is significantly reduced, which can reduce the space occupied in the length direction of the substrate, and make the edge structure of the flexible display module smaller, which is conducive to increasing the screen-to-body ratio of electronic devices.
[0068] Optionally, 0.08mm≤L1≤0.12mm.
[0069] Optionally, L1 = 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.1mm, 0.11mm, 0.12mm, 0.12mm, 0.13mm, 0.15mm.
[0070] like Figure 4 as well as Figure 5 As shown, in some embodiments, the first body includes a first plane covering the display body, the second body includes a second plane and a transition surface connecting the first plane and the second plane, and the transition surface cooperates with the first plane to form an avoidance groove. The transition surface is in the shape of an arc or an inclined surface. In this way, the first plane and the second plane are connected by the arc-shaped or inclined-shaped transition surface, which can reduce stress concentration, make the light-transmitting plate difficult to fold, and enhance the protective effect of the light-transmitting plate on the display panel.
[0071] like Figures 6 to 8 As shown, in some embodiments, the light-transmitting plate includes a UFG layer, and the avoidance groove is arranged in the UFG layer. The UFG layer has the characteristics of ultra-thinness, bendability and high durability. In this way, by setting the UFG layer to replace the polarizer, the thickness of the display module can be further reduced, and the power consumption of the flexible display module can be greatly improved.
[0072] In some embodiments, the display panel includes a color film and a black matrix integrated layer, and the UFG layer is covered on the color film and the black matrix integrated layer. In this way, when external light enters the screen, the unnecessary light will be absorbed by the black matrix in the color film and the black matrix integrated layer, and the remaining light will be incident through the RGB pixel points in the color film, and then the RGB pixel points will display color and reflect. It can be seen that the color film and the black matrix integrated layer can achieve light reflection and light transmission, so that the flexible display module does not need to be provided with a polarizer. Since the color film and the black matrix integrated layer can be formed by an evaporation process, its overall thickness is much smaller than the thickness of a conventional polarizer, and combined with the UFG layer, it has the characteristics of ultra-thinness, bendability and high durability. Therefore, the flexible display module in the above embodiment has the characteristics of low overall thickness and long service life.
[0073] like Figures 6 to 8 As shown, in some embodiments, the light-transmitting plate includes a support layer disposed outside the UFG layer, and the support layer is disposed away from the avoidance groove. The configuration of the support layer can provide explosion-proof protection for the UFG layer and improve the impact resistance of the light-transmitting plate.
[0074] Optionally, the support layer and the UFG layer are integrally formed, so that the thickness of the light-transmitting plate is smaller, and the thickness of the display screen module can be further reduced.
[0075] Alternatively, if Figure 7 As shown, in some embodiments, the support layer is disposed outside the UFG layer to be away from the display body. In this way, the impact resistance of the light-transmitting plate can be improved.
[0076] Alternatively, if Figure 8As shown, in some embodiments, the support layer is sandwiched between the display body and the UFG layer, so as to improve the impact resistance of the light-transmitting plate.
[0077] Alternatively, if Fig. 9 As shown, in some embodiments, the support layer includes two layers, and a UFG layer is sandwiched therebetween, so that the impact resistance of the light-transmitting plate can be improved.
[0078] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 As shown, in some embodiments, the flexible display module further includes a protective layer, which is attached to the back surface. In this way, the protective layer can buffer the pressure received by the flexible display module and improve the drop resistance of the flexible display module.
[0079] Optionally, in one embodiment, the protective layer includes a foam layer, so that the foam layer can better buffer the impact force.
[0080] In some embodiments, the protective layer further includes a mesh adhesive layer disposed between the foam layer and the back surface and an engineering film disposed between the foam layer and the shielding layer. In this way, the mesh adhesive layer can further buffer the impact force, and the mesh adhesive layer can be used to reliably fix the foam layer to the back surface of the substrate. The provision of the engineering film is also conducive to fixing the shielding layer on the foam layer.
[0081] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 As shown, in some embodiments, the flexible display module further includes a padding block, which is sandwiched between the binding body and the substrate. In this way, the padding block can be used to flexibly adjust the distance between the display body and the binding body in the thickness direction of the substrate, so that the bending body bends smoothly and avoids breaking.
[0082] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 As shown, in some embodiments, the flexible display module further includes a driving chip disposed on the binding body, so that the driving chip can be used to drive the flexible display device to display images.
[0083] Optionally, the binding body includes a printed circuit board, and the driving chip is arranged on the printed circuit board.
[0084] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 As shown, in some embodiments, the flexible display module further includes a transmission member disposed on the binding body. Thus, the transmission member is used to facilitate the communication connection between the flexible display module and other electronic devices (such as a control module, etc.).
[0085] Transmission components include flexible circuit boards, coaxial cables, etc.
[0086] like Figure 8 As shown, in some embodiments, the flexible display module further includes a support plate disposed between the protective layer and the padding block.
[0087] The electronic device may include handheld devices, vehicle-mounted devices, wearable devices, monitoring equipment, cellular phones, smart phones, personal digital assistants (PDA), tablet computers, laptop computers, laptop computers, cameras, video recorders, cameras, smart watches, smart wristbands, vehicle-mounted computers, unmanned aerial vehicles, unmanned ships, unmanned vehicles and other electronic devices with communication functions.
[0088] It can be understood that applying the technology of the present disclosure to tablet devices such as mobile phones and tablet computers is conducive to making the tablet devices lighter and thinner, thereby improving the grip feel and further enhancing the product competitiveness of the electronic devices of the present disclosure.
[0089] See you later Figure 1 As shown, the electronic device includes a foldable mobile phone. By using the flexible display module disclosed in the present invention, a lightweight design of the foldable mobile phone can be realized, so that the foldable mobile phone has a small thickness even after being folded, thereby improving the grip feel.

[0103] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0104] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
