[0047] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.
[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable 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, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0050] like Figures 1 to 16As shown, this embodiment provides a display device that can be applied to various terminal devices with flexible display requirements (such as mobile phones and tablet computers). The display device includes a flexible display screen 1, a rolling component 2 and a support component 3, and the rolling component 2 is used to roll up the flexible display screen 1. The support component 3 includes a plurality of support members 31 arranged at intervals, and the support members 31 are connected to the flexible display screen 1. Among the two adjacent support members 31, one is provided with a first connecting member 32, and the other is provided with a second connecting member 33. The adjacent first connecting member 32 and the second connecting member 33 are movably connected by a rotating shaft 34, and the adjacent first connecting member 32 and the second connecting member 33 can rotate relative to each other at a preset angle with the rotating shaft 34 as the axis.
[0051] When the flexible display screen 1 is in the unfolded state, the flexible display screen 1 is supported by a plurality of spaced support members 31, so that the flexible display screen 1 is evenly stressed. Since the adjacent first connecting member 32 and the second connecting member 33 are movably connected by the rotating shaft 34, an effective rigid constraint is formed between the two adjacent supporting members 31, and the flexible display screen 1 can be effectively rigidly supported and protected. When the rolling assembly 2 rolls up the flexible display screen 1, since the adjacent first connecting member 32 and the second connecting member 33 can rotate relative to each other at a preset angle with the rotating shaft 34 as the axis, an effective rigid constraint can still be formed between the two adjacent supporting members 31, and the flexible display screen 1 can be continuously and effectively rigidly supported and protected, thereby avoiding the flexible display screen 1 from wrinkling or over-stretching, or even reverse bending, extending the service life of the flexible display screen 1, and improving the user experience. Since the flexible display screen 1 can be extended out of the rolling assembly 2 and rolled into the rolling assembly 2, it is convenient to carry and can also meet the user's flexible display needs of different display areas, thereby improving the user experience.
[0052] Optionally, the rolling assembly 2 includes a fixed frame 21, a movable frame 22 and a reel 23. The movable frame 22 is slidably matched with the fixed frame 21, and the reel 23 is rotatably arranged on the movable frame 22 for rolling up the flexible display screen 1. One end of the flexible display screen 1 is fixedly connected to the fixed frame 21, and the other end is wound on the reel 23. When the rolling assembly 2 rolls up the flexible display screen 1, the reel 23 is rotated forward, and the reel 23 gradually rolls the flexible display screen 1 outside the movable frame 22 into the movable frame 22, and the flexible display screen 1 is rolled up and stored, so as to reduce the display area of the flexible display screen 1, and facilitate one-handed operation or carrying. Since the movable frame 22 is slidably matched with the fixed frame 21, during the rolling process of the flexible display screen 1, the movable frame 22 gradually approaches the fixed frame 21. When a flexible display screen 1 with a larger display area is required, the movable frame 22 is pulled to move the movable frame 22 away from the fixed frame 21, and the reel 23 rotates in the opposite direction, so that the flexible display screen 1 stored in the movable frame 22 gradually emerges from the movable frame 22. In order to realize the automatic reeling action, the reeling assembly 2 may further include a driving motor and a gear set for driving the reel 23 to rotate, and the output end of the driving motor transmits power to the reel 23 through the gear set.
[0053] Optionally, the flexible display screen 1 includes a rollable portion and a non-rollable portion connected to each other, and the support assembly 3 is disposed on the rollable portion. A portion of the rollable portion is wound around the reel 23, at least a portion of the rollable portion can be received in the movable frame 22, and one end of the non-rollable portion away from the rollable portion is fixedly connected to the fixed frame 21. Since the non-rollable portion does not need to be bent, there is no need to provide the support assembly 3 to support the non-rollable portion, thereby reducing the cost of the entire display device and reducing the weight of the entire display device.
[0054] Optionally, one of the adjacent first connecting member 32 and the second connecting member 33 is provided with a first receiving groove 321 and a first limiting groove 322 in communication, and the other is provided with a second receiving groove 331 and a second limiting groove 332 in communication, and the rotating shaft 34 includes a penetration portion 341 that penetrates the first receiving groove 321 and the second receiving groove 331 at the same time, and a limiting portion 342 that is provided on the penetration portion 341 and penetrates the first limiting groove 322 and the second limiting groove 332 at the same time, and the limiting portion 342 can rotate relative to the first limiting groove 322 and / or the second limiting groove 332, so that the adjacent first connecting member 32 and the second connecting member 33 can rotate relative to a preset angle. The limiting portion 342 can be cylindrical, and the first receiving groove 321 and the second receiving groove 331 can be circular accordingly, so as to facilitate the adjacent first connecting member 32 and the second connecting member 33 to rotate relative to each other with the rotating shaft 34 as the axis. In this embodiment, both ends of the first connecting member 32 are provided with a first accommodating groove 321 and a first limiting groove 322, and both ends of the second connecting member 33 are provided with a second accommodating groove 331 and a second limiting groove 332, thereby realizing the connection between any two adjacent supporting members 31, so that the entire supporting assembly 3 is evenly stressed when flattened or bent, and can provide continuous and effective rigid support protection for the flexible display screen 1, avoiding wrinkles or excessive stretching of the flexible display screen 1, or even reverse bending, thereby extending the service life of the flexible display screen 1 and improving the user experience.
[0055] Optionally, the limiting portion 342 is relatively stationary with the first limiting groove 322, and the limiting portion 342 can rotate relative to the second limiting groove 332; or, the limiting portion 342 is relatively stationary with the second limiting groove 332, and the limiting portion 342 can rotate relative to the first limiting groove 322. In this embodiment, the size of the first limiting groove 322 of the first connecting member 32 is the same as the size of the limiting portion 342 of the rotating shaft 34, so that the limiting portion 342 and the first limiting groove 322 cannot move relative to each other, thereby ensuring that the support assembly 3 has a certain rigidity. The size of the second limiting groove 332 of the second connecting member 33 is slightly larger than the size of the limiting portion 342 of the rotating shaft 34, so that the limiting portion 342 and the second limiting groove 332 can move relative to each other within a certain range, thereby ensuring that the support assembly 3 has a certain flexibility. The specific size of the second limiting groove 332 needs to be determined according to the preset angle of relative rotation of the adjacent first connecting member 32 and the second connecting member 33 with the rotating shaft 34 as the axis.
[0056] Optionally, the rotating shaft 34 includes two limiting portions 342, and the two limiting portions 342 are respectively arranged at the radial ends of the penetration portion 341. Two first limiting grooves 322 may be provided, and the two first limiting grooves 322 are symmetrically arranged at the radial ends of the first receiving groove 321, and two second limiting grooves 332 may be provided, and the two second limiting grooves 332 are symmetrically arranged at the radial ends of the second receiving groove 331, so as to achieve the connection of any two adjacent support members 31. In this embodiment, the two limiting portions 342 and the penetration portion 341 are in the shape of a cross shaft as a whole, the two first limiting grooves 322 and the first receiving groove 321 are in the shape of a cross hole as a whole, and the two second limiting grooves 332 and the second receiving groove 331 are in the shape of a cross hole as a whole. The first limiting groove 322 on the first connecting member 32 can extend in the horizontal direction, the first limiting grooves 322 at both ends of the first connecting member 32 are symmetrically arranged, the first limiting grooves 322 at both ends of the first connecting member 32 are flush, the extension direction of the second limiting groove 332 on the second connecting member 33 is inclined at a certain angle to the horizontal direction, the second limiting grooves 332 at both ends of the second connecting member 33 are symmetrically arranged, and the second limiting grooves 332 at both ends of the second connecting member 33 are in an eight-shaped shape.
[0057] To prevent the shaft 34 from being separated from the first connector 32 or the second connector 33, the shaft 34 may further include a stopper connected to the penetration portion 341, and the stopper may be in contact with the first connector 32 or the second connector 33. The stopper may be a limiting structure such as a pin to facilitate assembly.
[0058] Optionally, the first connecting member 32 and the second connecting member 33 respectively include a main body portion and a connecting portion connected to each other, the main body portion of the first connecting member 32 and the main body portion of the adjacent second connecting member 33 are movably connected through a rotating shaft 34, and the connecting portion is connected to the support member 31. In this embodiment, the main body portion of the first connecting member 32 is recorded as the first main body portion 323, the connecting portion of the first connecting member 32 is recorded as the first connecting portion 324, the first receiving groove 321 and the first limiting groove 322 are arranged on the first main body portion 323 of the first connecting member 32. The main body portion of the second connecting member 33 is recorded as the second main body portion 333, the connecting portion of the second connecting member 33 is recorded as the second connecting portion 334, the second receiving groove 331 and the second limiting groove 332 are arranged on the second main body portion 333 of the second connecting member 33. The first connecting portion 324 and the second connecting portion 334 can be integrally formed with the support member 31, or welded into an integral structure. The first main body portion 323 and the first connecting portion 324 can be integrally formed, or welded into an integral structure. The second body portion 333 and the second connection portion 334 may be integrally formed or welded into an integral structure. The first connection member 32 and the second connection member 33 may both be in the shape of a chain link, the first body portion 323 and the second body portion 333 may be in the shape of an oblong, and the first connection portion 324 and the second connection portion 334 may be in the shape of a square. The side surfaces of the first connection member 32 and the second connection member 33 may partially overlap and abut against each other.
[0059] In order to meet the requirements of different terminal devices for the curling degree of the flexible display screen 1, optionally, the preset angle ranges from 1° to 45°. Preferably, the preset angle ranges from 15° to 30°.
[0060] To prevent the support member 31 from scratching the flexible display screen 1, optionally, the support member 31 is made of a flexible material. The support member 31 and the flexible display screen 1 can be fixedly connected by bonding. The support member 31 can be made of the following flexible materials: polyvinyl alcohol (PVA), polyester (PET), polyimide (PI), polyethylene naphthalate (PEN), paper, textile materials, etc. Polyimide materials have the advantages of high temperature resistance, low temperature resistance, chemical resistance and good electrical properties. They are the most promising materials for flexible electronics. However, in addition to the high temperature resistance, the light transmittance, surface roughness and material cost of the flexible substrate are all factors that must be considered in the selection of flexible substrates. Polydimethylsiloxane (PDMS) is also a widely recognized flexible material. Its advantages include easy availability, stable chemical properties, transparency and good thermal stability. Especially under ultraviolet light, the distinct characteristics of the adhesion area and the non-adhesion area make it easy to adhere electronic materials to its surface. Although PET has a low conversion temperature, approximately between 70°C and 80°C, PET is inexpensive and has good light transmittance, making it a very cost-effective material for transparent conductive films.
[0061] It should be noted that the above-mentioned flexible display screen 1 refers to a flexible OLED (Organic Light-Emitting Diode). OLED is very thin and can be mounted on flexible materials such as plastic or metal foil. Using plastic instead of glass will make the display screen more durable and lighter. The flexible OLED panel is concave from top to bottom, and the bending radius can reach 700 mm. OLED uses a plastic substrate instead of a common glass substrate. It uses thin film encapsulation technology and sticks a protective film on the back of the panel to make the panel bendable and not easy to break.
[0062] OLED devices are composed of substrates, cathodes, anodes, hole injection layers (HIL), electron injection layers (EIL), hole transport layers (HTL), electron transport layers (ETL), electron blocking layers (EBL), hole blocking layers (HBL), and light-emitting layers (EML). Among them, the substrate is the basis of the entire device, and all functional layers need to be evaporated onto the substrate of the device; glass is usually used as the substrate of the device, but if a flexible OLED device needs to be made, other materials such as plastics need to be used as the substrate of the device. The anode is connected to the positive electrode of the device's external driving voltage. The holes in the anode will move to the light-emitting layer in the device under the drive of the external driving voltage. The anode needs to have a certain degree of light transmittance when the device is working, so that the light emitted from the inside of the device can be observed by the outside world; the most commonly used material for the anode is ITO.
[0063] The hole injection layer can modify the anode of the device and can smoothly inject holes from the anode into the hole transport layer; the hole transport layer is responsible for transporting holes to the light-emitting layer; the electron blocking layer will block the electrons from the cathode at the interface of the light-emitting layer of the device, increasing the concentration of electrons at the interface of the light-emitting layer of the device; the light-emitting layer is where the electrons and holes of the device recombine to form excitons and then the excitons de-excite to emit light; the hole blocking layer will block the holes from the anode at the interface of the light-emitting layer of the device, thereby increasing the probability of recombination of electrons and holes at the interface of the light-emitting layer of the device and increasing the luminescence efficiency of the device; the electron transport layer is responsible for transferring electrons from the cathode to the light-emitting layer of the device; the electron injection layer plays a role in modifying the cathode and transferring electrons to the electron transport layer; the electrons in the cathode will move to the light-emitting layer of the device under the drive of the device external driving voltage, and then recombine with the holes from the anode in the light-emitting layer.
[0064] Compared with traditional screens, flexible display screens1 have obvious advantages. They are not only thinner and lighter in size, but also consume less power than existing devices, which helps to improve the battery life of the device. At the same time, due to their bendability and flexibility, their durability is much higher than that of previous screens, reducing the probability of accidental damage to the device. The folding screen needs to be folded 200,000 times to remain intact. It is a flexible screen with high flexibility requirements, and the structure of the screen also needs to be designed separately.
[0065] In the display device provided in this embodiment, when the flexible display screen 1 is in the unfolded state, the flexible display screen 1 is supported by a plurality of spaced support members 31, so that the flexible display screen 1 is evenly stressed. Since the adjacent first connecting member 32 and the second connecting member 33 are movably connected by the rotating shaft 34, an effective rigid constraint is formed between the two adjacent supporting members 31, and the flexible display screen 1 can be effectively rigidly supported and protected. When the rolling assembly 2 rolls up the flexible display screen 1, since the adjacent first connecting member 32 and the second connecting member 33 can rotate relative to each other at a preset angle with the rotating shaft 34 as the axis, an effective rigid constraint can still be formed between the two adjacent supporting members 31, and the flexible display screen 1 can be continuously and effectively rigidly supported and protected, and the flexible display screen 1 is prevented from wrinkling or over-stretching, or even reverse bending, thereby extending the service life of the flexible display screen 1 and improving the user experience. Since the flexible display screen 1 can be extended out of the rolling assembly 2 and rolled into the rolling assembly 2, it is convenient to carry and can also meet the user's flexible display needs of different display areas, thereby improving the user experience.
[0066] It should be noted that the display device provided in this embodiment can be applied to terminal devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (PDA), and can also be applied to databases, servers, and service response systems based on terminal artificial intelligence. This embodiment does not impose any restrictions on the specific types of terminal devices.

[0068] As an example but not limitation, when the above-mentioned terminal device is a wearable device, the wearable device can also be a general term for wearable devices that are intelligently designed and developed by applying wearable technology to daily wear, such as gloves and watches equipped with near-field communication modules. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. It is attached to the user and performs payment, authentication and other operations through a pre-bound electronic card. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those with full functions, large sizes, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application functions and need to be used in conjunction with other devices such as smartphones, such as various types of smart watches and smart bracelets with display screens.
[0069] As an example, the terminal device may also communicate with the network and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to Global System of Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.
[0070] This embodiment also provides a terminal device, including the above-mentioned display device, and the terminal device can be a mobile phone, a tablet computer, or other wearable devices. When the flexible display screen 1 is in the unfolded state, the flexible display screen 1 is supported by a plurality of spaced support members 31, so that the flexible display screen 1 is evenly stressed. Since the adjacent first connecting member 32 and the second connecting member 33 are movably connected by the rotating shaft 34, an effective rigid constraint is formed between the two adjacent supporting members 31, and the flexible display screen 1 can be effectively rigidly supported and protected. When the rolling component 2 rolls the flexible display screen 1, since the adjacent first connecting member 32 and the second connecting member 33 can be relatively rotated at a preset angle with the rotating shaft 34 as the axis, an effective rigid constraint can still be formed between the two adjacent supporting members 31, and the flexible display screen 1 can be continuously and effectively rigidly supported and protected, and the flexible display screen 1 is prevented from wrinkling or over-stretching, or even reverse bending, thereby extending the service life of the flexible display screen 1 and improving the user experience. Since the flexible display screen 1 can be extended out of the rolling component 2 and rolled into the rolling component 2, it is convenient to carry and can also meet the user's flexible display requirements of different display areas, thereby improving the user experience. The product is novel, highly recognizable, suitable for a wide range of people and scenarios. The screen rolls up and unfolds smoothly and naturally, is easy to operate, not easy to damage, has a long service life, and provides a good user experience.
[0071] In terms of hardware system, terminal equipment has a central processing unit, memory, input components and output components, that is, terminal equipment is often a microcomputer device with communication function. In addition, terminal equipment can have multiple input methods, such as keyboard, mouse, touch screen, microphone and camera, etc., and the input can be adjusted as needed. At the same time, terminal equipment often has multiple output methods, such as receiver, display screen, etc., which can also be adjusted as needed.
[0072] In terms of software system, terminal devices must have operating systems, such as Windows Mobile, Symbian, Palm, Android, iOS, etc. At the same time, these operating systems are becoming more and more open, and personalized application software developed based on these open operating system platforms is emerging in an endless stream, such as address books, calendars, notepads, calculators, and various games, which meet the needs of personalized users to a great extent.
[0073] In terms of communication capabilities, the terminal equipment has flexible access methods and high-bandwidth communication performance, and can automatically adjust the selected communication method according to the selected service and the environment, so as to facilitate user use. The terminal equipment can support GSM, WCDMA, CDMA2000, TDSCDMA, Wi-Fi and WiMAX, etc., so as to adapt to various standard networks, and support not only voice services, but also various wireless data services.
[0074] In terms of functional use, terminal devices pay more attention to humanization, personalization and multi-function. With the development of computer technology, terminal devices have entered the "people-centered" mode from the "device-centered" mode, integrating embedded computing, control technology, artificial intelligence technology and biometric authentication technology, fully reflecting the people-oriented purpose. Due to the development of software technology, terminal devices can adjust settings according to personal needs and become more personalized. At the same time, the terminal devices themselves integrate a lot of software and hardware, and their functions are becoming more and more powerful.
