Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.

The embodiment of the application provides a flexible display device and electronic equipment. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Referring to fig. 1, fig. 1 is a schematic view illustrating a first structure of a flexible display device according to an embodiment of the present disclosure. 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 bent state and a flattened state. The adjusting structure 102 is disposed below the flexible display module 101. When the flexible display module 101 is in a bent state, the adjusting structure 102 is arranged in a curled state, and the adjusting structure 102 has a first stiffness. When the flexible display module 101 is in a flat state, the adjusting structure 102 is arranged in a flat state, and the adjusting structure 102 has a second stiffness. 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 side surface of the adjusting structure 102 away from the flexible display module 101.

For the first stiffness being smaller than the second stiffness, it can be understood that when the flexible display module 101 is in a bending state, the adjusting structure 102 has flexibility and curls with the flexible display module 101. When the flexible display module 101 is in the flat 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 rolled state, the adjusting structure 102 has flexibility, i.e., the first stiffness approaches zero. When the flexible display module 101 is in the flat state, the adjusting structure 102 has 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 diffuser film, a quantum dot film, a light directing film, a reflective film, or a brightness enhancing film. The diffusion film can be used for improving the optical quality and the adsorption phenomenon between 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 a light source on the backlight and converting a point light source of the light emitting diode into a surface light source. The reflecting film is used for controlling the reflection and refraction of light rays, so that the path of the light rays is controllable, and the brightness of the display panel is more uniform. Brightness enhancement films are used to improve the luminous efficiency of the overall backlight system.

The flexible display device 100 provided in the embodiment of the present application includes a flexible display module 101, an adjustment structure 102, and a buffer structure 103. The adjusting structure 102 enables the flexible display module 101 to maintain the flatness of the flexible display module 101 without an external force, and does not affect the curling of the flexible display module 101. Since the flexible display device 100 is in the rolled and unrolled state, the adjustment structure 102 also has two states with different stiffness. Therefore, many complicated rotating mechanisms and designs of motors and the like can be omitted, thereby simplifying the structure of the flexible display device 100 and reducing the cost. In addition, a buffering structure 103 is arranged below the adjusting structure 102, so that buffering can be performed when the rigidity of the adjusting structure 102 changes, and the flexible display module 101 is protected.

Optionally, the adjusting structure 102 includes an accommodating portion 1021 and an adjusting portion 1022. The adjustment portion 1022 is housed in the housing portion 1021. When the flexible display module 101 is in a bending state, the adjusting portion 1022 has a first stiffness. When the flexible display module 101 is in the flattened state, the adjusting portion 1022 has a second stiffness. Specifically, the adjustment part 1022 may be a solid-liquid conversion material or a gas.

The solid-liquid conversion regulating material can be converted from a liquid to a solid under specific conditions. For example, a magnetorheological fluid is contained within the containment structure. Magnetorheological fluids (Magnetorheological fluids) are novel fluids with controlled flow. Exhibit low viscosity newtonian fluid behavior in the absence of an external magnetic field. Presents a high viscosity, low flow bingham fluid upon application of a magnetic field. In a popular way, when no magnetic field exists outside, the magnetorheological fluid has the crimpability 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 a supporting property, and can be used for supporting the flexible display module 101 in a flat state.

Wherein, the magnetic particles in the magnetorheological fluid can be subjected to surface modification, thereby improving the compatibility and the dispersibility of the polar magnetic metal and the non-polar carrier liquid. Commonly used stabilizers are surfactants and coupling agents. Or, nano particles or nano wires are added into the magnetorheological fluid. By adjusting the composition and collocation of the dispersed phase, the structural form of the microstructure of the magnetic chain under the action of a magnetic field is improved, so that the aim of improving the magneto-rheological effect is fulfilled.

Therefore, the magnetorheological effect of the magnetorheological fluid can be adjusted, so that the solid-liquid conversion adjusting structure has better adjustability and is suitable for the support requirements of different flexible display devices 100.

Specifically, an electric field may be applied to the magnetorheological fluid by electrodes within the flexible display module 101. For example, the lines in the flexible display module 101 form a potential difference, and further form a horizontal electric field to change the state of the magnetorheological fluid. Alternatively, electrodes are fabricated on both sides of the flexible display device 100, and a vertical electric field is formed by forming a potential difference to 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 present disclosure. The accommodating portion 1021 is an airbag 1021a, and the regulating portion 1022 is a gas 1022 a. The adjustment mechanism 102 further includes an airway 1023, an air valve 1024, and an air pump 1025. The air bag 1021a is arranged below the flexible display module 101. The air pump 1025 is disposed inside 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 illustrated. The air duct 1023 is arranged below the flexible display module 101 and is connected with the air pump 1025 and the air bag 1021 a. The air valve 1024 is disposed between the air guide tube 1023 and the air pump 1025.

Since the flexible display device 100 needs to perform the function of curling, 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 secured. By providing the air bag 1021a, the flexibility of the flexible display module 101 is achieved in a deflated state. 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, the air bag 1021a is filled with air, and the flexible display module 101 is driven to recover the flatness. In addition, the air is supplied to the air bag 1021a through the air pump 1025, so that the air bag 1021a has higher rigidity and can support the flexible display module 101.

Optionally, the air bag 1021a is in a strip shape, and the air bag 1021a is arranged along the bending direction of the flexible display module. The air bag 1021a is arranged along the bending direction of the flexible display module 101. The air bag 1021a is arranged to be long-strip-shaped and arranged along the bending direction of the flexible display module 101, so that the air bag 1021a has better support performance in the flattening state of the flexible display module 101.

Specifically, the length of the air bag 1021a may be less than or equal to the length of the flexible display module 101. That is, the air bag 1021a may be as shown in fig. 1 and fig. 2, and one strip may cover the flexible display module 101. The arrangement of the long air bag 1021a can simplify the structure of the flexible display device 100 and reduce the thickness of the flexible display device 100.

Alternatively, the air cell 1021a may be a shorter strip. The air bags 1021a are arranged on the flexible display module 101 in a staggered manner along the bending direction of the flexible display module 101. Providing a plurality of staggered air cells 1021a may increase the thickness uniformity of the flexible display device 100.

Wherein, the thickness of the air bag 1021a is between 0.3 mm and 2 mm. Specifically, the thickness of the air bag 1021a can 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 air bladder 1021a may also be other values between 0.3 mm and 2 mm. The thickness of the air bag 1021a can be adaptively designed according to the size, thickness and weight of the flexible display module 101. Since the greater the thickness of the air bag 1021a, the better its support, the greater the second rigidity. Therefore, when the flexible display module 101 requires a higher strength support in the flattened state, the thickness of the air bag 1021a should be increased.

Alternatively, one air bag 1021a is provided. An air bag 1021a is arranged at the central axis of the flexible display module 101. When the air bags 1021a are arranged in one, better supporting effect can be obtained by arranging the air bags 1021a at the middle axis of the flexible display module 101. The provision of only one air bag 1021a can greatly simplify the structure of the flexible display device 100.

Alternatively, two air bags 1021a are provided. The two air bags 1021a are arranged on two sides of the flexible display module 101. The two air bags 1021a are arranged on two sides of the flexible display module 101, so that the flexible display module 101 can be supported most effectively by using the simplest structure of the supporting module 102. It is understood that two air bags 1021a may be disposed at both sides near the end of the flexible display module 101 as shown in fig. 1 and 2. Further, the two air bags 1021a can be symmetrically arranged on two sides of the flexible display module 101.

It should be noted that the present embodiment is described by taking one air bag 1021a and two air bags 1021a as an example. In practical applications, a plurality of air bags 1021a may be disposed on the flexible display module 101, and the number of the air bags 1021a may be adjusted according to the size of the flexible display device 100.

Alternatively, the gas 1022a may be an inert gas. Specifically, one or a combination of more of helium, argon, and neon may be used. Inert gas is safer, adopts inert gas can prevent that gas leakage from producing the influence to flexible display module 101.

Optionally, the air duct 1023 is provided with a plurality of air holes H. The air hole H communicates the air duct 1023 and the air bag 1021 a. Further, a plurality of air holes H may be uniformly distributed on the air guide tube 1023. The air holes H can make the air duct 1023 deliver air in the air bag 1021a more uniformly and quickly. Thereby when flexible display module assembly 101 is by the state of buckling to the state change of flattening, can be faster support flexible display module assembly 101.

Optionally, the pore diameter 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 aperture of the air hole H is too small, the air bag 1021a cannot be inflated quickly; if the diameter of the air hole H is too large, the possible inflation speed cannot be controlled, and the air bag 1021a cannot be uniformly inflated during inflation.

The air duct 1023 is used for inflating and deflating the air bag 1021 a. Optionally, the air duct 1023 is laid on the side of the air bag 1021a away from the flexible display module 101. Alternatively, when the balloon 1021a is small in area, for example, arranged in a long strip shape, the airway tube 1023 may be arranged between the balloons 1021 a. Such a design may increase the contact area between the airway 1023 and the balloon 1021a, thereby allowing more uniform and rapid inflation and deflation. In addition, the air duct 1023 is arranged between the air bags 1021a, so that the thickness of the flexible display device 100 can be reduced, the flexible display device 100 is lighter and thinner, and the flexible display device is easier to bend.

Optionally, the aperture of the air duct 1023 is between 0.2 mm and 2 mm. Specifically, the aperture of the airway tube 1023 can 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 the flexible display module 101 cannot provide good support in time when being flat; or too slow in deflation, which affects the bending of the flexible display module 101. The aperture of the air duct 1023 should not be too large. If the aperture of airway tube 1023 is too large, this may result in uneven inflation, causing the airway tube 1023 to partially expand.

Referring to fig. 3, fig. 3 is a schematic view of a second structure of a flexible display device according to an embodiment of the present disclosure. Fig. 3 shows a schematic view of the flexible display device 100 in a bent state. The flexible display device 100 further comprises a rotation axis 107. The shaft 107 may be a hollow shaft, and the shaft 107 may be disposed around the flexible display device 100. The rotation shaft 107 can be in transmission connection with a motor to drive the flexible display module 101 to roll or unroll. The air pump 1025 can be disposed inside the shaft 107 and connected to the balloon 1021a through the air tube 1023. This saves space.

In addition, the flexible display module 101 can be driven to roll or unroll by a single-side motor. The motor and the air pump 1025 can be connected with a driving circuit board of the flexible display module 101, and the driving circuit board is adopted to synchronously drive the motor and the air pump 1025 to work, so that the air pump 1025 and the driving electrode work in a coordinated mode, and the flexible display module 101 can be better curled and unfolded.

Optionally, referring to fig. 1 and fig. 4, fig. 4 is a schematic structural diagram of a third flexible display device according to an embodiment of the present disclosure. Fig. 4 shows a schematic configuration of the flexible display device after the air cell 1021a is inflated. Wherein the buffer structure 103 comprises a buffer protection layer 1031 and a grid protection layer 1032. The buffer protection layer 1031 is disposed on a side of the adjusting structure 102 away from the flexible display module 101, and covers the adjusting structure 102. The mesh protective layer 1032 is covered to the adjusting structure 102 by the buffer protective layer 1031 on the side away from the adjusting structure 102.

The buffer protection layer 1031 is made of a rubber material. The cushioning protective layer 1031 is used to protect the regulating structure 102, for example, the cushioning protective layer 1031 may protect the airway tube 1023. The cushion protection layer 1031 is made of a rubber material, so that the air duct 1023 can be tightly attached to the air bag 1021a and cannot be separated. When the air duct 1023 is used for conveying gas, the buffer protection layer 1031 can enable the air duct 1023 to be kept flat, and the problem that the air duct 1023 is extruded in the curling process and then unsmooth ventilation is avoided.

Optionally, the buffer protection layer 1031 may adopt oca (optical Clear adhesive) optical glue, glass glue or other adhesive material. When the OCA optical cement is used for surface connection, the strength is higher. Therefore, the OCA optical cement can ensure the connection stability. In addition, the OCA laminating can make the product surface more level and smooth, avoids the problem of uneven thickness, and then can avoid the influence of curling and unfolding the flexible display device 100.

Wherein the mesh protection layer 1032 is a mesh structure. The mesh protective layer 1032 covers the cushion protective layer 1031, the airway tube 1023 and the balloon 1021 a. During inflation, the airbag 1021a is prevented from rupturing due to local expansion. Also, providing the mesh protective layer 1032 can control the thickness of the air bag 1021 a.

Optionally, with continued reference to fig. 1, the flexible display device 100 further includes a support structure 104. The support structure 104 is disposed under the flexible display module 101. The adjusting structure 102 is disposed on a side of the supporting structure 104 away from the flexible display module 101.

Optionally, the support structure 104 includes a first support membrane 1041 and a second support membrane 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 supporting film 1042 has a hollow pattern 1042 a.

Optionally, the thickness of the second support film 1042 is between 0.02 mm and 0.5 mm. 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. The second support film 1042 with a proper thickness can ensure the flatness of the screen and protect the back of the screen from being damaged by 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 diagram of a second support film in a flexible display device according to an embodiment of the present disclosure. The second supporting film 1042 has a hollow pattern 1042 a. Since the second supporting film 1042 is usually made of a metal material, in order to ensure the flatness of the second supporting film 1042 and prevent the second supporting film 1042 from warping, the elastic modulus of the second supporting film 1042 can be reduced by etching and hollowing out, so that the flexible display module 101 can be curled or folded according to the design.

Optionally, the hollow-out pattern 1042a is a plurality of strip-shaped through holes arranged at intervals, and a distance D1 between the strip-shaped through holes is between 0.2 mm and 2 mm. The width D2 of the strip-shaped through hole is between 0.2 mm and 1 mm. Specifically, the distance D1 between the strip-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 strip-shaped via 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 distance D1 and the width D2 between the bar-shaped through holes can jointly define the hollow area and hollow degree of the hollow pattern 1042 a. The second support film 1042 needs to design the hollow pattern 1042a with a suitable hollow degree. If the hollow degree is too large, the flexible display module 101 cannot be supported well. If the hollow degree is too small, the flexible display module 101 cannot have good flexibility, and the flexible display module is affected to be curled or folded. Specifically, the specification and size of the hollow-out pattern 1042a can be adaptively designed according to the size of the flexible display module 101 and the curling radius of the flexible display module 101, which is not specifically limited in this application.

Optionally, an adhesive layer 105 is further disposed 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 material. When the OCA optical cement is used for surface connection, the strength is higher. Therefore, the OCA optical cement can ensure the connection stability. In addition, the OCA laminating can make the product surface more level and smooth, avoids the problem of uneven thickness, and then can avoid the influence of curling and unfolding the flexible display device 100.

Correspondingly, the embodiment of the application also provides the electronic equipment. Referring to fig. 6, fig. 6 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 1000 comprises the flexible display apparatus 100 and the encapsulation structure 200. The flexible display device 100 is the flexible display device 100 described in any of the above, and the encapsulation structure 200 is disposed on the flexible display device 100.

The electronic device 1000 provided by the embodiment of the application comprises the flexible display device 100. The flexible display device 100 includes a flexible display module, an adjustment structure, and a buffer structure. The structure is adjusted to make flexible display module can keep the planarization of flexible display module, do not influence flexible display module again and curl under the condition of not with the help of external force. The adjustment structure also has two states with different stiffness due to the flexible display device in the rolled and unrolled state.
