All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the application. In the present application, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used to generally refer to the upper and lower positions of the device in actual use or operation, and specifically the orientation of the drawing figures; while "inner" and "outer" are for the outline of the device.
The embodiment of the application provides a flexible display device and electronic equipment. The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 1, fig. 1 is a schematic diagram of a first structure of a flexible display device according to an embodiment of the application. The flexible display device 100 includes a flexible display module 101, an adjustment structure 102, and a buffer structure 103. The flexible display module 101 has a curved state and a flattened state. The adjustment structure 102 is arranged below the flexible display module 101. When the flexible display module 101 is in a bending state, the adjusting structure 102 is curled, and the adjusting structure 102 has a first rigidity. When the flexible display module 101 is in the flattened state, the adjusting structure 102 is arranged in a flattened state, and the adjusting structure 102 has a second rigidity. Wherein the first stiffness is less than the second stiffness. The buffer structure 103 is disposed on a side of the adjusting structure 102 away from the flexible display module 101, and at least covers a surface of the adjusting structure 102 away from the flexible display module 101.
The first stiffness is smaller than the second stiffness, and it is understood that the adjustment structure 102 has flexibility and curls with the flexible display module 101 when the flexible display module 101 is in a bending state. When the flexible display module 101 is in the flattened state, the rigidity of the adjusting structure 102 is increased for supporting the flexible display module 101.
It should be noted that, when the flexible display module 101 is in the curled state, the adjusting structure 102 has flexibility, i.e., the first stiffness approaches zero. When the flexible display module 101 is in the flattened state, the adjustment structure 102 has a rigidity, i.e., the second rigidity approaches infinity.
The flexible display device 100 further comprises a support structure 104, an adhesive layer 105 and an optical structure 106. The specific assembly of the support structure 104 and the adhesive layer 105 will be described in detail below.
The optical structure 106 includes a polarizer, and may further include one or more of a diffusion film, a quantum dot film, a light guiding film, a reflective film, or a brightness enhancing film. The diffusion film can be used for improving optical taste and improving adsorption phenomenon of the film and the polarizer under the panel. The quantum dot film can be used for exciting red and green quantum dots by a blue light-emitting diode, so that full-color display is achieved. The light guide film is used for guiding out the light source on the backlight and converting the point light source of the light emitting diode into a surface light source. The reflective film is used for controlling the reflection and refraction of light, so that the light path is controllable, and the brightness of the display panel is more uniform. The brightness enhancement film is used to improve the overall backlight system luminous efficiency.
The flexible display device 100 provided by the embodiment of the application comprises a flexible display module 101, an adjusting structure 102 and a buffer structure 103. The adjusting structure 102 enables the flexible display module 101 to keep the flatness of the flexible display module 101 without external force, and the curling of the flexible display module 101 is not affected. Since the flexible display device 100 is in the rolled and unrolled state, the adjustment structure 102 also has two states with different rigidities. Therefore, many complicated rotating mechanisms, motors, and the like can be omitted, thereby simplifying the structure of the flexible display device 100 and reducing the cost. In addition, a buffer structure 103 is arranged below the adjusting structure 102, and can buffer when the rigidity of the adjusting structure 102 changes, so as to protect the flexible display module 101.
Optionally, the adjusting structure 102 includes a receiving portion 1021 and an adjusting portion 1022. The adjusting portion 1022 is accommodated in the accommodation portion 1021. The adjusting portion 1022 has a first rigidity when the flexible display module 101 is in a bent state. The adjusting portion 1022 has a second rigidity when the flexible display module 101 is in the flattened state. Specifically, the adjusting portion 1022 may be a solid-liquid conversion material or a gas.
The solid-liquid conversion regulating material may be converted from a liquid to a solid under certain conditions. For example, magnetorheological fluid is contained within a containing structure. The magneto-rheological fluid (Magnetorheological Fluid) is a novel fluid with controllable fluidity. Exhibits Newtonian fluid behavior of low viscosity in the absence of an external magnetic field. The guest-han fluid exhibits high viscosity and low fluidity when a magnetic field is applied. In popular terms, when no magnetic field exists outside, the magnetorheological fluid has crimping property and can be bent along with the bending of the flexible display module 101; when an external magnetic field is applied, the magnetorheological fluid has supporting property and can be used for supporting the flexible display module 101 in a flattened state.
The magnetic particles in the magnetorheological fluid can be subjected to surface modification, so that the compatibility and the dispersibility of polar magnetic metals and nonpolar carrier fluid are improved. Commonly used stabilizers are surfactants and coupling agents. Alternatively, nanoparticles or nanowires are added to the magnetorheological fluid. By adjusting the composition and the collocation of the disperse phase, the structural form of the microstructure of the flux linkage under the action of the magnetic field is improved, so that the purpose of improving the magneto-rheological effect is achieved.
Therefore, the magnetorheological effect of the magnetorheological fluid can be adjusted, so that the solid-liquid conversion adjusting structure has better adjustability, and meets the supportability requirements of different flexible display devices 100.
Specifically, an electric field may be applied to the magnetorheological fluid through electrodes within the flexible display module 101. For example, a potential difference is formed by using the trace in the flexible display module 101, so as to form a horizontal electric field to change the state of the magnetorheological fluid. Alternatively, electrodes are formed on both sides of the flexible display device 100, and a vertical electric field is formed by forming a potential difference between the electrodes, so as to change the state of the magnetorheological fluid.
Optionally, referring to fig. 1 and fig. 2, fig. 2 is a schematic structural diagram of an adjusting structure in a flexible display device according to an embodiment of the application. The accommodation portion 1021 is an airbag 1021a, and the adjustment portion 1022 is a gas 1022a. The adjustment structure 102 further includes an air duct 1023, an air valve 1024, and an air pump 1025. The airbag 1021a is disposed under the flexible display module 101. The air pump 1025 is disposed within the flexible display module 101. Since the flexible display module 101 is not shown in fig. 2, the position of the air pump 1025 is only schematic. The air duct 1023 is disposed below the flexible display module 101 and connects the air pump 1025 and the air bag 1021a. The air valve 1024 is disposed between the air duct 1023 and the air pump 1025.
Since the flexible display device 100 needs to realize a curling function, the flexibility of the flexible display device 100 is great. And thus the rigidity of the flexible display device 100 in a flat state cannot be ensured. By providing the airbag 1021a, the flexibility of the flexible display module 101 is achieved in a state of being out of air. When the flexible display module 101 needs to be stretched, the air pump 1025 is used for supplying air, the air valve 1024 is opened, the air duct 1023 is conducted, so that the air bag 1021a is filled with air, and the flexible display module 101 is driven to restore flatness. In addition, since the air is supplied into the air bag 1021a through the air pump 1025, the air bag 1021a has high rigidity, and can support the flexible display module 101.
Alternatively, the airbag 1021a is in a bar shape, and the airbag 1021a is disposed along a bending direction of the flexible display module. The airbag 1021a is disposed along the bending direction of the flexible display module 101. The airbag 1021a is arranged in a strip shape and along the bending direction of the flexible display module 101, so that the airbag 1021a has better support in the flattened state of the flexible display module 101.
Specifically, the length of the airbag 1021a may be less than or equal to the length of the flexible display module 101. That is, the airbag 1021a may be a length of one bar as shown in fig. 1 and 2 that covers the flexible display module 101. Providing a long length of the airbag 1021a can better simplify the device structure of the flexible display device 100 and reduce the thickness of the flexible display device 100.
Alternatively, the balloon 1021a may be a shorter strip. The plurality of the air bags 1021a are alternately arranged on the flexible display module 101 along the bending direction of the flexible display module 101. Providing a plurality of the staggered airbags 1021a may increase the thickness uniformity of the flexible display device 100.
Wherein the thickness of the bladder 1021a is between 0.3 mm and 2 mm. Specifically, the thickness of the bladder 1021a may be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm. It is understood that the thickness of the bladder 1021a may be other values between 0.3 mm and 2 mm. The thickness of the airbag 1021a may be adaptively designed according to the size, thickness, and weight of the flexible display module 101. Since the larger the thickness of the airbag 1021a is, the better the support thereof is, the larger the second rigidity is. Therefore, when the flexible display module 101 requires a support of higher strength in the flattened state, the thickness of the airbag 1021a should be increased.
Optionally, the balloon 1021a is provided with one. One airbag 1021a is disposed at the center axis of the flexible display module 101. When the airbag 1021a is provided as one, the airbag 1021a can be provided at the center axis of the flexible display module 101 to achieve a better supporting effect. Providing only one airbag 1021a can greatly simplify the structure of the flexible display device 100.
Alternatively, the airbag 1021a is provided with two. Two airbags 1021a are provided on both sides of the flexible display module 101. Two airbags 1021a are provided on both sides of the flexible display module 101, and the flexible display module 101 can be supported most effectively with the simplest structure of the support module 102. It is understood that two airbags 1021a may be provided on both sides near the end of the flexible display module 101 as shown in fig. 1 and 2. Further, two airbags 1021a may be symmetrically disposed on both sides of the flexible display module 101.
Note that, the embodiment of the present application is described taking one airbag 1021a and two airbags 1021a as examples. In practical applications, a plurality of the airbags 1021a may be provided on the flexible display module 101, and the number of the airbags 1021a may be adjusted according to the size of the flexible display device 100.
Alternatively, the gas 1022a may be an inert gas. In particular, one or more combinations of helium, argon, and neon may be employed. The inert gas is safer, and the inert gas can prevent gas leakage from affecting the flexible display module 101.
Optionally, a plurality of air holes H are provided on the air duct 1023. The air hole H communicates the air duct 1023 with the airbag 1021a. Further, the plurality of air holes H may be uniformly distributed on the air duct 1023. The provision of the gas holes H makes it possible to make the gas-guide tube 1023 more uniform and faster for the gas to be supplied into the airbag 1021a. Thus, when the flexible display module 101 is changed from the bent state to the flattened state, the flexible display module 101 can be supported more quickly.
Optionally, the pore size of the air hole H is between 0.2 mm and 1 mm. Specifically, the pore diameter of the air hole H may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm. If the pore diameter of the air hole H is too small, the air bag 1021a cannot be inflated rapidly; if the pore diameter of the air hole H is too large, the inflation speed may not be controlled, and the airbag 1021a may not be uniformly inflated at the time of inflation.
The air duct 1023 is used for inflating and deflating the air bag 1021a. Optionally, the air duct 1023 is laid on the side of the airbag 1021a remote from the flexible display module 101. Alternatively, when the area of the airbag 1021a is small, for example, provided in a long strip shape, the air duct 1023 may be provided between the airbags 1021a. Such a design may increase the contact area between the airway 1023 and the bladder 1021a, thereby allowing for more uniform and rapid inflation and deflation. In addition, the air duct 1023 is disposed between the airbags 1021a, which can reduce the thickness of the flexible display device 100, and make the flexible display device 100 lighter and thinner, and thus more flexible.
Optionally, the air duct 1023 has an aperture of 0.2 mm to 2 mm. Specifically, the aperture of airway 1023 may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm. The aperture of the air duct 1023 is not too small, otherwise the inflation speed may be too slow, and good support cannot be provided in time when the flexible display module 101 is flat; or too slow in deflation, affecting bending of the flexible display module 101. The aperture of airway 1023 is preferably not too large. If the aperture of the air duct 1023 is too large, this may cause uneven inflation, causing the air duct 1023 to expand locally.
Referring to fig. 3, fig. 3 is a schematic diagram of a second structure of the flexible display device according to the embodiment of the application. Fig. 3 shows a schematic view of the flexible display device 100 in a bent state. The flexible display device 100 further includes a rotation shaft 107. The rotating shaft 107 may be a hollow rotating shaft, and the rotating shaft 107 may be sleeved on the periphery of the flexible display device 100. The rotation shaft 107 may be in driving connection with a motor to drive the flexible display module 101 to curl or unfold. An air pump 1025 may be provided in the rotation shaft 107 and connected to the airbag 1021a through an air duct 1023. This saves space.
In addition, the flexible display module 101 may be driven to curl or spread by a single-side motor. The motor and the air pump 1025 can be connected with the driving circuit board of the flexible display module 101, and the motor and the air pump 1025 are synchronously driven by the driving circuit board to work, so that the air pump 1025 and the driving electrode work cooperatively, and the flexible display module 101 is in a better curled and unfolded state.
Optionally, referring to fig. 1 and fig. 4, fig. 4 is a schematic view of a third structure of a flexible display device according to an embodiment of the application. Fig. 4 shows a schematic structure of the flexible display device after the airbag 1021a is inflated. The buffer structure 103 includes a buffer protection layer 1031 and a mesh protection layer 1032. The buffer protection layer 1031 is disposed on a side of the adjustment structure 102 away from the flexible display module 101, and covers the adjustment structure 102. The mesh protection layer 1032 is covered to the adjustment structure 102 by a side of the buffer protection layer 1031 remote from the adjustment structure 102.
The buffer protection layer 1031 is made of a glue material. The buffer protection layer 1031 is used to protect the adjusting structure 102, for example, the buffer protection layer 1031 may protect the air duct 1023. The cushion protection layer 1031 is made of a plastic material, so that the air duct 1023 is tightly attached to the airbag 1021a without detachment. When the air duct 1023 is used for conveying air, the buffer protection layer 1031 can keep the air duct 1023 flat, so that the air duct 1023 is prevented from being extruded in the curling process, and the problem of unsmooth ventilation is further avoided.
Alternatively, the buffer protection layer 1031 may use OCA (Optically Clear Adhesive) optical cement, glass cement or other adhesive materials. When OCA optical cement is adopted for surface connection, the strength is higher. Therefore, the OCA optical cement can ensure the connection stability. In addition, the OCA lamination can make the product surface smoother, avoid the problem of uneven thickness, and then can avoid the influence on the curling and unfolding of the flexible display device 100.
Wherein the mesh protection layer 1032 is a mesh structure. The mesh protection layer 1032 encloses the buffer protection layer 1031, the airway 1023, and the balloon 1021a. During inflation, the airbag 1021a can be prevented from being ruptured by local inflation. Also, the provision of the mesh protection layer 1032 can control the thickness of the airbag 1021a.
Optionally, with continued reference to fig. 1, the flexible display device 100 further includes a support structure 104. The support structure 104 is arranged below the flexible display module 101. The adjustment structure 102 is arranged at a side of the support structure 104 remote from the flexible display module 101.
Optionally, the support structure 104 includes a first support film 1041 and a second support film 1042. The first support film 1041 is disposed under the flexible display module 101. The second support film 1042 is disposed on a side of the first support film 1041 away from the flexible display module 101. The second support film 1042 has a hollow pattern 1042a thereon.
Optionally, the thickness of the second support film 1042 is between 0.02 millimeters and 0.5 millimeters. Specifically, the thickness of the second support film 1042 may be 0.02 mm, 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm. Setting the second support film 1042 to an appropriate thickness can ensure flatness of the screen and protect the back of the screen from other components, thereby improving the bending life of the flexible display module 101.
Optionally, referring to fig. 5, fig. 5 is a schematic partial structure of a second support film in the flexible display device according to an embodiment of the application. The second support film 1042 has a hollow pattern 1042a thereon. Since the second support film 1042 is usually made of a metal material, in order to ensure the flatness of the second support film 1042 and prevent the second support film 1042 from warping, the elastic modulus of the second support film 1042 can be reduced by etching and hollowing, so that the flexible display module 101 can be curled or folded according to the design.
Optionally, the hollowed pattern 1042a is a plurality of bar-shaped through holes arranged at intervals, and the distance D1 between the bar-shaped through holes is between 0.2 mm and 2 mm. The width D2 of the strip-shaped through holes is between 0.2 mm and 1 mm. Specifically, the spacing D1 between the bar-shaped through holes may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2 mm. The width D2 of the bar-shaped through holes may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm. The space D1 and the width D2 between the bar-shaped through holes can jointly define the hollowed-out area and the hollowed-out degree of the hollowed-out pattern 1042a. The second support film 1042 needs to be provided with a hollowed-out pattern 1042a at a proper hollowed-out degree. If the hollow-out degree is too large, the flexible display module 101 cannot be well supported. If the hollow-out degree is too small, the flexible display module 101 cannot be better flexible, and further the curling or folding of the flexible display module is affected. Specifically, the size of the hollowed-out pattern 1042a can be adaptively designed according to the size of the flexible display module 101 and the curl radius of the flexible display module 101, which is not particularly limited in the present application.
Optionally, an adhesive layer 105 is further provided between the first support film 1041 and the second support film 1042. The adhesive layer 105 is used to connect the first support film 1041 and the second support film 1042. The adhesive layer 105 may be made of OCA optical cement, glass cement or other adhesive materials. When OCA optical cement is adopted for surface connection, the strength is higher. Therefore, the OCA optical cement can ensure the connection stability. In addition, the OCA lamination can make the product surface smoother, avoid the problem of uneven thickness, and then can avoid the influence on the curling and unfolding of the flexible display device 100.
Correspondingly, the embodiment of the application also provides electronic equipment. Referring to fig. 6, fig. 6 is a schematic structural diagram of an electronic device according to an embodiment of the application. The electronic device 1000 includes a flexible display device 100 and a package structure 200. The flexible display device 100 is any one of the above flexible display devices 100, and the package structure 200 is disposed on the flexible display device 100.
The electronic device 1000 provided by the embodiment of the application comprises a flexible display device 100. The flexible display device 100 includes a flexible display module, an adjustment structure, and a buffer structure. The adjusting structure enables the flexible display module to keep the flatness of the flexible display module without external force and does not influence the curling of the flexible display module. Since the flexible display device is in the rolled and unfolded state, the adjustment structure also has two states with different rigidities. Therefore, many complicated rotating mechanisms, motors, and the like can be omitted, thereby simplifying the structure of the flexible display device and reducing the cost.
