[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] In the related art, flexible display screens have significant advantages over traditional display screens. First of all, flexible display screens have the advantages of low power consumption, small size, and excellent picture quality. Due to the adoption of new materials and technologies, flexible display screens can greatly reduce energy consumption, thereby extending the battery life of devices, and can be applied in multiple fields, thus enhancing the user experience. Moreover, flexible display screens are smaller and thinner, capable of significantly reducing the thickness and weight of devices, and improving the portability of devices. At the same time, due to the adoption of advanced display technologies such as OLED (organic light-emitting diode), flexible display screens perform excellently in terms of picture quality, with higher contrast, richer colors, and faster response times, providing an excellent visual experience. Secondly, flexible display screens can be bent, which provides possibilities for a variety of innovative application scenarios. Flexible display screens can be freely folded or bent according to user needs, thereby switching between multiple display forms. This flexibility enables flexible display screens to be widely used in various scenarios, greatly enhancing the human-computer interaction of devices, and thus improving the user experience. However, although flexible display screens have multiple technical advantages, in the actual use process of users, the bending operation of flexible display screens is not convenient and smooth, affecting people's use experience. Exemplarily, although flexible display screens have the ability to switch between multiple forms, the thickness of flexible display screens is relatively thin, and users need to be more cautious during actual operation. That is, in order to avoid improper operation, users need to be extra careful when folding and unfolding flexible display screens, and try their best to prevent damage to the flexible screen caused by improper operation. This undoubtedly makes users feel inconvenient when using flexible screens. At the same time, although flexible display screens can be bent, there is usually a limit to the minimum bending radius. If users bend the screen excessively beyond the design limit of its materials and structure, the screen may be damaged, which may cause irreversible damage to the device inadvertently for users, and thus affect the user experience.

[0037] Based on this, a first aspect of the present disclosure provides a display device, referring to Figures 1 to 6As shown, the display device includes: a flexible display component 1, a mounting frame 2 and a driving component 3, wherein the flexible display component 1 has an unfolded state and a bent state. When the user uses it, the flexible screen can be bent or unfolded according to the user's own usage habits and viewing state. The mounting frame 2 has a mounting portion 203 for connecting the flexible display component 1 and a supporting portion 204 for supporting the flexible display component 1 in a bent state, that is, one end of the flexible display component 1 along its own length direction is connected to the mounting portion 203 of the mounting frame 2. When the flexible display component 1 is in the unfolded state, the end away from the mounting portion 203 is located above the supporting portion 204, and there is a gap between the back side of the flexible display component 1 and the upper surface of the supporting portion 204. When the flexible display component 1 is in the bent state, the back side of the flexible display component 1 is attached to the supporting portion 204 of the mounting frame 2, and then the flexible display component 1 in the bent state is supported by the supporting portion 204, so that the flexible display component 1 maintains a stable structure in the bent state to avoid deformation or damage caused by external pressure or its own weight. The support portion 204 can effectively disperse external forces and provide reliable mechanical support, thereby ensuring that the display component can still work normally after bending without affecting the display effect; the driving component 3 is arranged on the mounting frame 2 and the driving end of the driving component 3 is connected to the back side of the flexible display component 1, so that the flexible display component 1 switches from the unfolded state to the bent state or from the bent state to the unfolded state.

[0038] In some embodiments, the driving component 3 includes an airbag and an air pump connected to the airbag, the airbag has a connecting portion connected to the flexible display component 1, the amount of gas in the airbag can be controlled by the air pump, when the airbag is filled with gas, the flexible display component 1 is in an expanded state, when the air pump evacuates the gas in the airbag, the flexible display component 1 is in a bent state, and a through groove 202 for accommodating the airbag and the air pump is provided on the mounting frame 2, so that when the flexible display component 1 is in a bent state, the back side of the flexible display component 1 can fit against the supporting portion 204 of the mounting frame 2.

[0039] In some embodiments, the outer surface profile of the support portion 204 should match the bending radius of the flexible display component 1, so that the flexible display component 1 in a bent state can better fit the support portion 204, providing good support for the flexible display component 1 in the bent state, thereby effectively preventing local stress concentration, avoiding permanent creases or damage to the flexible display component 1, extending the service life of the flexible display component 1, and enhancing the user experience.

[0040] Through the above technical solution, the driving component 3 enables the flexible display component 1 to conveniently and flexibly switch between the unfolded state and the bent state, improving the flexibility of the flexible display component 1, enabling it to adjust its form according to different scenario requirements, meeting the diverse usage methods of users, and thus giving users a better sense of usage experience; in the unfolded state, the flexible display component 1 can provide a larger and more complete display area, which is suitable for scenarios such as watching videos and multitasking, while in the bent state, the flexible display component 1 can be bent into a smaller form, enhancing the aesthetics of the display device. Moreover, the support portion 204 of the mounting frame 2 provides mechanical support in the bent state of the flexible display component 1, enabling the bent flexible display component 1 to remain stable, and improving the reliability of the flexible display component 1 in the bent state.

[0041] The driving component 3 is connected to the back side of the flexible display component 1 to achieve automatic form switching of the flexible display component 1, effectively reducing the complexity of manual operation by the user. The folding or unfolding of the flexible display component 1 can be completed through button or touch operations, greatly enhancing the user experience. At the same time, the driving component 3 can precisely control the unfolding speed of the flexible display component 1 to ensure that each form switch is smooth and seamless, avoiding sudden or stuck situations that may occur during manual operation.

[0042] Through the control of the support portion 204 of the mounting frame 2 and the driving component 3, the flexible display component 1 realizes stable switching between the bent and unfolded states, improving the flexibility, operation convenience, and service life of the display device, and can provide users with a more comfortable and smooth usage experience.

[0043] In some embodiments, referring to Figure 1 and Figure 4 as shown, the flexible display component 1 includes an anti-reflection film layer 101, a cover plate layer 102, a polarizing layer 103, a display layer 104, a protective layer 105, and a support layer 106 that are sequentially stacked. Any two adjacent layers among the anti-reflection film layer 101, the cover plate layer 102, the polarizing layer 103, the display layer 104, the protective layer 105, and the support layer 106 are connected by an adhesive layer;

[0044] The anti-reflection film layer 101 includes a 3A film, and the base material of the 3A film is PET (polyethylene terephthalate), which is used to reduce the reflectivity of the module surface, that is, to reduce the amount of light reflected from the surface of the display layer 104 back into the user's eyes by ambient light (such as sunlight and indoor lighting);

[0045] Among them, the PET material has good optical transparency, which can enable the light source of the display screen to be transmitted to the outside more efficiently, ensuring the clarity of the display effect. At the same time, the PET material has high mechanical strength, which can withstand the wear and stretching in daily use, ensuring the long service life of the 3A film.

[0046] The cover layer 102 includes a glass cover plate, which has the properties of high hardness, scratch resistance, and impact resistance, and can ensure the good flatness of the flexible display component 1.

[0047] The polarizer layer 103 is a circular polarizer, which is composed of a linear polarizer and a quarter-wave plate. Among them, the linear polarizer is responsible for converting the incident light into linearly polarized light, playing the role of controlling and filtering light; the quarter-wave plate is responsible for converting the linearly polarized light into circularly polarized light, so that the circular polarizer plays an anti-reflection role in the flexible display component 1.

[0048] The display layer 104 includes an OLED (organic light-emitting diode) screen, which is responsible for image display. The OLED screen has the self-luminous characteristic, which can provide higher contrast, fast response time, and wider viewing angle.

[0049] The protective layer 105 includes a back protective film (Bottom Film). The base material of the back protective film is PET material. The back protective film is used to protect the back of the display layer 104, help fix the OLED screen and other components, and also play a protective role such as dust prevention, moisture prevention, and scratch prevention.

[0050] The support layer 106 includes a metal support sheet. A support sheet made of stainless steel can be selected, which is located at the bottom of the display module and provides strong mechanical support for the whole structure.

[0051] In some embodiments, refer to Figure 3As shown, the adhesive layer includes a first adhesive layer 4 and a second adhesive layer 5. A first adhesive layer 4 is provided between the anti-reflection film layer 101 and the cover plate layer 102, a first adhesive layer 4 is provided between the cover plate layer 102 and the polarizer layer 103, a second adhesive layer 5 is provided between the polarizer layer 103 and the display layer 104, a second adhesive layer 5 is provided between the display layer 104 and the protective layer 105, and a first adhesive layer 4 is provided between the protective layer 105 and the support layer 106. Among them, the first adhesive layer 4 can be made of OCA glue (optical clear adhesive). OCA glue is a highly transparent adhesive material, specifically used for bonding optical components in displays, such as glass, polarizers, display screens, etc., to ensure that light can pass through without obstruction and does not affect the display effect. At the same time, OCA glue has very good transparency and anti-bubble properties, and is suitable for laminated structures that require strict control of optical properties; the second adhesive layer 5 can be made of PSA glue (pressure-sensitive adhesive). PSA glue can achieve adhesion by applying pressure, without additional heat or chemical reactions. PSA exhibits different moduli under different temperature conditions and can adapt to different bonding requirements of the flexible display component 1 in hot and cold environments.

[0062] In some embodiments, referring to Figure 4 andFigure 5 As shown, it also includes a support block 6, wherein the support block 6 is fixedly connected to the side of the support layer 106 away from the protective layer 105. When the flexible display component 1 is in a bent state, the end face of the support block 6 away from the support layer 106 is in contact with the outer wall of the support portion 204. At this time, the support block 6 plays the role of a gasket, that is, the support block 6 can effectively avoid the support block 6 directly contacting the outer wall of the support portion 204, and plays the role of an isolation layer, effectively avoiding the support layer 106 directly contacting the outer wall of the support portion 204, and effectively preventing friction and wear caused by direct contact, thereby protecting the integrity of the flexible display component 1 and avoiding structural damage after long-term use or multiple bending. At the same time, the support block 6, as a gasket, can provide a certain buffering effect.

[0063] In some embodiments, reference Figure 4 and Figure 5 As shown, two groups of support blocks 6 are arranged at intervals along the width direction of the support layer 106, and the number of support blocks 6 in each group is multiple, and the multiple support blocks 6 in each group are arranged at equal intervals along the length direction of the support layer 106, wherein the multiple support blocks 6 are arranged at intervals in the length direction and width direction of the support layer 106, which can provide more comprehensive support for the flexible display component 1, thereby improving the overall stability in the bent state, and the arrangement of multiple support blocks 6 can make each support block 6 bear less force, thereby reducing the wear rate of a single support block 6, and further reducing the replacement frequency of the support blocks 6.

[0064] In some embodiments, reference Figures 4 to 6 As shown, the edge profile of the support block 6 is trapezoidal, and the interval between two adjacent support blocks 6 gradually increases along the height direction of the support block 6, that is, when the flexible display component 1 switches from the unfolded state to the bent state through the driving component 3, in order to prevent the flexible display component 1 from being over-folded (the bending radius exceeds R400mm), resulting in damage to the flexible display component 1, a plurality of support blocks 6 can be used for bending limit, so as to prevent the flexible display component 1 from being over-folded (the bending radius exceeds R400mm). When the flexible display component 1 switches from the unfolded state to the bent state through the driving component 3, the interval between two adjacent support blocks 6 gradually decreases. When the flexible display component 1 is in the bent state, the side wall surfaces between the two adjacent support blocks 6 abut against each other, and the abutment between the support blocks 6 can prevent the flexible display component 1 from being over-folded.

[0065] In some embodiments, reference Figure 5As shown in the figure, the installation frame 2 has a storage cavity 201 for storing the driving component 3. A through groove 202 is provided on the support portion 204 for the driving end of the driving component 3 to extend out of the storage cavity 201. During the process of the flexible display component 1 switching from the bent state to the unfolded state through the driving component 3, the driving end of the driving component 3 gradually extends out of the storage cavity 201 through the through groove 202. Similarly, during the process of the flexible display component 1 switching from the unfolded state to the bent state through the driving component 3, the driving end of the driving component 3 gradually retracts into the storage cavity 201 through the through groove 202. When the flexible display component 1 is in the bent state, refer to Figure 1 As shown in the figure, the flexible display component 1 covers above the through groove 202 to block the through groove 202, making the display device more beautiful and tidy.

[0066] In some embodiments, refer to Figure 5 As shown in the figure, the driving component 3 includes a first driver 301 and a second driver 302. A connecting plate 3021 for connecting the output rotating shaft of the first driver 301 is provided on the second driver 302. The driving end is configured as the output push rod 3022 of the second driver 302. An articulated ear plate 7 for connecting the output push rod 3022 is provided on the side of the support layer 106 away from the protective layer 105. Among them, the articulated ear plate 7 is arranged at one end far from the installation portion 203. The first driver 301 is a rotary motor, and the second driver 302 is a telescopic motor. The output shaft of this telescopic motor is the output push rod 3022. The output rotating shaft of the first driver 301 is connected to the connecting plate 3021 provided on the second driver 302, so that the output rotating shaft of the first driver 301 can drive the second driver 302 to rotate. Because the output push rod 3022 of the second driver 302 is connected to the support layer 106 through the articulated ear plate 7, at this time, under the coordinated action of the first driver 301 and the second driver 302, the flexible display component 1 can be driven to switch states, that is, the output rotating shaft of the first driver 301 can change the rotation angle of the second driver 302, and the second driver 302 can change the telescopic amount of the output push rod 3022. By correctly matching the rotation angle and the telescopic amount, during the process of the flexible display component 1 switching from the unfolded state to the bent state through the driving component 3, the connection part between the output push rod 3022 and the support layer 106 presents an involute motion trajectory, thereby realizing the state switching of the flexible display component 1.

[0067] In some embodiments, refer to Figure 7 As shown in the figure, in order to accurately control the rotation angle of the first driver 301 and the telescopic amount of the second driver 302, the calculation method of the corresponding telescopic amount at different rotation angles;

[0068] The calculation method specifically refers to:

[0069]

[0070] Among them, the reference Figure 7 shows that the length of the flexible display component 1 participating in the bending deformation (when the flexible display component 1 is in the bent state, the part of the flexible display component 1 located at the support part 204) is L (L = L1 + L2), where the bending starting point coordinates are (x0, y0), and the coordinates of the end point of the screen bending are (x i , y i ). During the bending process, the length of the bent part of the flexible display component 1 is L1, and the length of the unbent part of the flexible display component 1 is L2. The initial inclination angle of the flexible display component 1 is θ, the rotation angle is α, and the inclination angle of the flexible display component 1 after rotation is L a is the length of the line connecting the starting point and the end point of the bent part of the flexible display component 1, and L b is the length of the line connecting the tangent line of the end point of the flexible display component 1 and the Y-axis.
