Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display device and its control method. Background Technology

[0002] Early vehicles typically used mechanical switches on their multi-function steering wheels to interact with the vehicle's infotainment system and control related electronic systems. This resulted in a lack of intelligent information display capabilities, failing to meet the needs of drivers and passengers for convenient operation of driving information and related intelligent driving assistance functions. To address these issues, the central control screen in vehicles has been enhanced with intelligent display functionality, allowing drivers to interact with the vehicle through the screen's intelligent display system. Currently, most automotive displays use LCD (Liquid Crystal Display) screens. LCD display technology is relatively mature and meets the requirements of in-vehicle testing conditions. Simultaneously, new demands have been placed on automotive displays, such as thinner and lighter designs, higher contrast ratios, and wider color gamuts. OLED (Organic Light-Emitting Diode) displays, with their wide color gamut, high contrast ratios, energy efficiency, and foldability, have become one of the most competitive technologies in next-generation display devices. Their applications are widespread, including smart wearable devices, and therefore, OLED displays are gradually entering the automotive display field.

[0003] However, in current technology, vehicle center console screens are mostly flat displays, such as LCD or flat OLED screens. These rigid screens typically have a fixed, non-adjustable angle. Furthermore, due to the presence of the steering wheel and other components, the center console screen is usually positioned relatively far from the driver, requiring the driver to turn their head to operate it. This causes the driver's gaze to wander off the road while the vehicle is in motion, affecting driving safety. In bright environments, such as during daytime driving, ambient light and interior glare result in low screen contrast, hindering the driver's ability to see the displayed content and compromising driving safety. While existing technologies utilize head-up displays (HUDs) to project vehicle information onto the windshield or within two meters of the driver's direct line of sight to improve safety, these systems are complex and expensive. While clearer in low light conditions, strong light necessitates increasing the brightness of the display devices to achieve sufficient contrast, significantly increasing power consumption.

[0004] Therefore, providing a display device and its control method that can automatically adjust the screen rotation and angle according to the user's location, thereby improving user safety and display contrast, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a display device and its control method to solve the problems of low safety of existing displays used in the field of vehicle display and poor contrast under special environments, which affects the viewing effect.

[0006] This invention discloses a display device, comprising: a flexible display module and a support, wherein the flexible display module includes a supporting back plate located on one side of the backlight surface of the flexible display module; the flexible display module also includes a plurality of sensor components; wherein the support is fixed to the supporting back plate by a universal joint, one end of the universal joint is fixed to the supporting back plate, and the other end of the universal joint is fixed to the support, and the sensor components are electrically connected to the universal joint through a first motor assembly; and / or, the supporting back plate includes a hinge assembly, and the sensor components are electrically connected to the hinge assembly through a second motor assembly.

[0007] Based on the same inventive concept, the present invention also discloses a control method for a display device, which is applied to the aforementioned display device; the control method includes: a sensor sensing the location of the user; a first motor assembly controlling the rotation of a universal structure so that the light-emitting surface of the flexible display module faces the user; and / or, a second motor assembly controlling the bending of a hinge assembly to adjust the curvature of the flexible display module.

[0008] Compared with the prior art, the display device and control method provided by the present invention achieve at least the following beneficial effects:

[0009] The display device provided by this invention includes a flexible display module and a support. The flexible display module includes a supporting back plate disposed on one side of the backlight surface of the flexible display module. The supporting back plate provides support for the flexible display panel, allowing the user to view the display image from the light-emitting side of the flexible display module. This invention incorporates sensors electrically connected to a universal joint via a first motor assembly. Feedback information sensed by the sensors, such as user position feedback or sound feedback, is transmitted to the first motor assembly. The first motor assembly calculates and transmits kinetic energy to the universal joint, causing it to change its direction. This, in turn, controls the direction of the supporting back plate, thereby changing the direction of the flexible display module and ensuring that the light-emitting surface of the flexible display module faces the user as much as possible, achieving a better viewing angle for the user. And / or, the present invention sets the sensor to be electrically connected to the hinge assembly via the second motor assembly. The feedback information sensed by the sensor, such as the user's position feedback, sound feedback, etc., is transmitted to the second motor assembly. After the second motor assembly calculates and transmits the kinetic energy to the hinge assembly, it causes the hinge assembly to change its curvature, such as changing from a planar shape to a curved shape, or from a curved shape with a smaller curvature to a curved shape with a larger curvature, thereby controlling the curvature of the support back plate to change the curvature of the flexible display module. By setting the light-emitting surface of the flexible display module to a curved shape, the light-emitting surface of the flexible display module is made to face the user as much as possible, achieving a better viewing angle for the user. The display device of this invention can be applied to the central control screen area of ​​an in-vehicle display system. Even if the display device is far from the driver's position, the light-emitting surface of the flexible display module can be adjusted to face the driver at a better angle by controlling the first motor assembly and the universal joint, and the second motor assembly and the hinge assembly, according to the driver's position. This allows the driver to view the display screen of the flexible display module without turning their head during human-vehicle interaction, enabling screen operation when needed. This also prevents the driver's gaze from leaving the driving direction while the vehicle is in motion, further improving driving safety. Furthermore, after the flexible display module's light-emitting surface is oriented towards the user under the control of the universal joint, the hinge assembly can control the light-emitting surface of the flexible display module to have different degrees of curvature. Within the user's viewing range, this effectively blocks ambient light, improving the contrast when viewing the display device and thus allowing the user to achieve the best possible viewing experience and increasing user satisfaction.

[0010] Of course, any product implementing this invention need not necessarily achieve all of the technical effects described above at the same time.

Figure 9 yes Figure 8 A schematic diagram of the electrical connection structure between the sensor and the hinge assembly. Figure 10 yes Figure 8 and Figure 9 The diagram shown illustrates the effect of the display device being used in an in-vehicle display system (it should be understood that this diagram is for the purpose of clearly illustrating the structure of this embodiment). Figure 1 The display device 000 provided in this embodiment includes: a flexible display module 10 and a bracket 20. The flexible display module 10 includes a support back plate 101, which is located on one side of the backlight surface 10B of the flexible display module 10. The flexible display module 10 also includes a plurality of sensor devices 102.

[0066] The bracket 20 is fixed to the support back plate 101 via a universal joint 30. One end of the universal joint 30 is fixed to the support back plate 101, and the other end is fixed to the bracket 20. The sensor 102 is electrically connected to the universal joint 30 via a first motor assembly 401 (e.g., Figures 2-3 (as shown); and / or,

[0067] The support backplate 101 includes a hinge assembly 1011, and the sensor 102 is electrically connected to the hinge assembly 1011 via a second motor assembly 402 (e.g., Figure 5 and Figure 6 (As shown).

[0068] Specifically, the display device 000 provided in this embodiment includes a flexible display module 10 and a bracket 20. The flexible display module 10 is a flexible display screen. For example, the flexible display module 10 may include a supporting back plate 101. Optionally, the flexible display module 10 may also include a flexible display panel 103. The supporting back plate 101 is disposed on one side of the backlight surface 10B of the flexible display module 10. The supporting back plate 101 is used to provide support for the flexible display panel 103. The light-emitting surface 10A of the flexible display module 10 is the light-emitting surface of the flexible display panel 103. The flexible display panel 103 can be an organic light-emitting diode display panel. Users can view the display screen on the side of the light-emitting surface 10A of the flexible display module 10.

[0069] like Figure 1 , Figure 2 , Figure 3As shown, on one side of the backlight surface 10B of the flexible display module 10, one end of a universal structure 30 is fixed to the supporting back plate 101, and the other end of the universal structure 30 is fixed to the bracket 20. The bracket 20 is fixed to the supporting back plate 101 through the universal structure 30. The rotation of the supporting back plate 101 can be controlled through the universal structure 30, thereby controlling the rotation of the flexible display module 10. The display device 000 in this embodiment can be a display device for an in-vehicle display system. The display device 000 provided in this embodiment can be installed in the central control screen area of ​​the in-vehicle display system through the bracket 20. Optionally, the universal structure 30 in this embodiment can be a universal joint or a robotic arm structure. The universal joint or robotic arm can rotate in one direction or in multiple directions. This embodiment does not limit this, as long as the universal structure 30 is fixed to the supporting back plate 101 and the rotation of the supporting back plate 101 can be controlled through the universal structure 30. The flexible display module 10 of this embodiment also includes a plurality of sensor elements 102. The plurality of sensor elements 102 can be all disposed in the non-display area of ​​the flexible display module 10, or the plurality of sensor elements 102 can be partially disposed on one side of the backlight surface 10B of the flexible display module 10, or they can be disposed in other positions, etc. This embodiment does not limit this, as long as the plurality of sensor elements 102 included in the flexible display module 10 do not affect the display effect on the light-emitting surface 10A side of the flexible display module 10, and do not affect the sensing effect of the sensor elements 102.

[0070] In this embodiment, the sensor 102 is electrically connected to the universal structure 30 via the first motor assembly 401. Feedback information sensed by the sensor 102, such as user position feedback and sound feedback, is transmitted to the first motor assembly 401. The first motor assembly 401 calculates and transmits kinetic energy to the universal structure 30, causing the universal structure 30 to change its direction. By controlling the universal structure 30 through the first motor assembly 401, the rotation of the supporting backplate 101 is controlled, thereby changing the rotation of the flexible display module 10. This ensures that the light-emitting surface 10A of the flexible display module 10 faces the user as much as possible, achieving a better viewing angle for the user. Figure 4 As shown, when the display device 000 is applied to the central control screen area J1 of the vehicle display system, even if the display device 000 is far from the driver M, it can still be directed towards the driver M via the control of the first motor assembly 401 and the universal structure 30, based on the driver M's location. (e.g., ...) Figure 4The diagram shows the effect of the light-emitting surface 10A of the flexible display module 10 facing the driver M after the first motor assembly 401 controls the universal structure 30 to rotate. Thus, when interacting with the vehicle, the driver can view the display screen of the light-emitting surface 10A of the flexible display module 10 without turning his head. When necessary, the driver can operate the screen. During vehicle operation, the driver's eyes can be kept away from the driving direction, which helps to improve driving safety.

[0071] Optionally, the first motor assembly 401 can be installed on one side of the backlight surface 10B of the flexible display module 10 (not shown in the attached diagram), or the first motor assembly 401 can also be installed inside the bracket 20 (e.g., Figure 2 As shown, in order to avoid affecting the light emission effect of the display device 000, it is only necessary to ensure that the first motor assembly 401 is electrically connected to the sensor 102 and the universal structure 30 respectively.

[0072] Or, such as Figure 1 , Figure 5 and Figure 6 As shown, the flexible display module 10 of this embodiment may include a hinge assembly 1011 disposed within a support back plate 101. The hinge assembly 1011 may include multiple hinges, and each hinge may include multiple links. It is understood that this embodiment does not limit the structure of the hinge assembly 1011, as long as the hinge assembly 1011 is disposed within the support back plate 101, the bending degree of the support back plate 101 can be changed by bending the hinge assembly 1011, thereby changing the bending degree of the entire flexible display module 10. The display device 000 of this embodiment can be a display device for an in-vehicle display system. The display device 000 provided in this embodiment can be installed in the central control screen area of ​​the in-vehicle display system through the bracket 20. The flexible display module 10 of this embodiment also includes a plurality of sensor elements 102. The plurality of sensor elements 102 can be all disposed in the non-display area of ​​the flexible display module 10, or the plurality of sensor elements 102 can be partially disposed on one side of the backlight surface 10B of the flexible display module 10, or they can be disposed in other positions, etc. This embodiment does not limit this, as long as the plurality of sensor elements 102 included in the flexible display module 10 do not affect the display effect on the light-emitting surface 10A side of the flexible display module 10, and do not affect the sensing effect of the sensor elements 102.

[0073] In this embodiment, the sensor 102 is electrically connected to the hinge assembly 1011 via the second motor assembly 402. Feedback information sensed by the sensor 102, such as user position feedback and sound feedback, is transmitted to the second motor assembly 402. The second motor assembly 402 calculates the kinetic energy transmitted to the hinge assembly 1011, causing the hinge assembly 1011 to change its curvature, such as from a planar shape to a curved surface, or from a surface with less curvature to a surface with greater curvature. This allows the second motor assembly 402 to control the hinge assembly 1011, thereby controlling the curvature of the support back plate 101 and changing the curvature of the flexible display module 10. By setting the light-emitting surface 10A of the flexible display module 10 to a curved shape, the light-emitting surface 10A of the flexible display module 10 is made to face the user as much as possible, achieving a better viewing angle for the user. Figure 7 As shown, when the display device 000 is applied to the central control screen area J1 of the vehicle display system, even if the display device 000 is far from the driver M, it can still be adjusted according to the driver M's location by controlling the second motor assembly 402 and the hinge assembly 1011 to make the light-emitting surface 10A of the flexible display module 10 curved and facing the driver M (e.g., ...). Figure 7 The diagram shows the effect of the light-emitting surface 10A of the flexible display module 10 facing the driver M after the second motor assembly 402 controls the hinge assembly 1011 to bend. This allows the driver to view the display screen of the light-emitting surface 10A of the flexible display module 10 without turning their head during human-vehicle interaction, and to perform screen operations when needed. This also prevents the driver's eyes from leaving the driving direction during vehicle operation, which helps improve driving safety.

[0074] Optionally, the second motor assembly 402 can be installed on one side of the backlight surface 10B of the flexible display module 10 (not shown in the attached diagram), or the second motor assembly 402 can also be installed inside the bracket 20 (e.g., Figure 5 As shown, in order to avoid affecting the light emission effect of the display device 000, it is only necessary to ensure that the second motor assembly 402 is electrically connected to the sensor 102 and the hinge assembly 1011 respectively.

[0075] Or, such as Figure 1 , Figure 8 and Figure 9As shown, on one side of the backlight surface 10B of the flexible display module 10, one end of a universal structure 30 is fixed to the support back plate 101, and the other end of the universal structure 30 is fixed to the bracket 20. The bracket 20 is fixed to the support back plate 101 through the universal structure 30. The universal structure 30 can be used to control the rotation of the support back plate 101, thereby controlling the rotation of the flexible display module 10. At the same time, a hinge assembly 1011 can also be provided inside the support back plate 101. The hinge assembly 1011 can include multiple hinges, and each hinge can include multiple links. It is understood that the structure of the hinge assembly 1011 is not limited in this embodiment. It is only required that when the hinge assembly 1011 is provided inside the support back plate 101, the bending degree of the support back plate 101 can be changed by the bending of the hinge assembly 1011, thereby changing the bending degree of the entire flexible display module 10. The display device 000 in this embodiment can be a display device for an in-vehicle display system. The display device 000 provided in this embodiment can be installed in the central control screen area of ​​the in-vehicle display system via the bracket 20. Optionally, the universal structure 30 in this embodiment can be a universal joint or a robotic arm structure. The universal joint or robotic arm can rotate in one direction or in multiple directions. This embodiment does not limit this, as long as the universal structure 30 is fixed to the support back plate 101, the rotation of the support back plate 101 can be controlled through the universal structure 30. The flexible display module 10 of this embodiment also includes a plurality of sensor elements 102. The plurality of sensor elements 102 can be all disposed in the non-display area of ​​the flexible display module 10, or the plurality of sensor elements 102 can be partially disposed on one side of the backlight surface 10B of the flexible display module 10, or they can be disposed in other positions, etc. This embodiment does not limit this, as long as the plurality of sensor elements 102 included in the flexible display module 10 do not affect the display effect on the light-emitting surface 10A side of the flexible display module 10, and do not affect the sensing effect of the sensor elements 102.

[0076] In this embodiment, sensor 102 is electrically connected to the universal joint 30 via a first motor assembly 401, and also electrically connected to the hinge assembly 1011 via a second motor assembly 402. Feedback information sensed by sensor 102, such as user position feedback and voice feedback, is transmitted to the first motor assembly 401. The first motor assembly 401 calculates and transmits the kinetic energy to the universal joint 30, causing the universal joint 30 to change its direction. Thus, the first motor assembly 401 controls the universal joint 30, thereby controlling the direction of the support backplate 101, and consequently changing the direction of the flexible display module 10. Simultaneously, the feedback information sensed by sensor 102, such as user position feedback and voice feedback, also... The energy can be transmitted to the second motor assembly 402. After calculating and transmitting the kinetic energy to the hinge assembly 1011, the second motor assembly 402 causes the hinge assembly 1011 to change its curvature, such as changing from a planar shape to a curved shape, or from a curved surface with less curvature to a curved surface with greater curvature. This allows the second motor assembly 402 to control the hinge assembly 1011, thereby further controlling the curvature of the support backplate 101 while the orientation of the light-emitting surface 10A of the flexible display module 10 changes. This changes the curvature of the flexible display module 10, and by setting the light-emitting surface 10A of the flexible display module 10 to a curved shape, the light-emitting surface 10A of the flexible display module 10 is further oriented towards the user, achieving a better viewing angle for the user. Figure 9 As shown, when the display device 000 is applied to the central control screen area J1 of the vehicle display system, even if the display device 000 is far from the driver M, it can still adjust the light-emitting surface 10A of the flexible display module 10 to face the driver M at a better angle by controlling the first motor assembly 401 and the universal structure 30, the second motor assembly 402 and the hinge assembly 1011 according to the driver M's position. Thus, when interacting with the vehicle, the driver can see the display screen of the light-emitting surface 10A of the flexible display module 10 without turning his head, and perform screen operations when needed. During vehicle operation, the driver's eyes can be kept away from the driving direction, which is conducive to further improving driving safety. Furthermore, when the flexible display module 10 faces the user with its light-emitting surface 10A under the control of the omnidirectional structure 30, the hinge assembly 1011 controls the light-emitting surface 10A of the flexible display module 10 to be curved at different degrees. This can also block ambient light within the user's viewing range, which helps to improve the contrast when the user views the display device 000, thereby helping the user achieve the best viewing effect and improve user satisfaction. In addition, the structure of this embodiment is simple and does not require the setting of a high-cost and high-power head-up display system, which helps to save costs.

In specific implementations, the flexible display module 10 may include not only the flexible display panel 103 and the supporting back plate 101, but also other functional structures. For details, please refer to the structure of the flexible display screen in related technologies. This embodiment will not elaborate further here.

The positions of the first region P1 and the second region P2 are different. Further optionally, the first region P1 can be understood as the original orientation region of the display device 000 in its original state, that is, when the omnidirectional structure 30 has not received a rotation command. The second region P2 can be understood as the region that the sensor device 102 in the display device 000 senses the user's position and the omnidirectional structure 30 faces after receiving a rotation command.

Figure 13 Taking the first surface 101A as a plane as an example, the second surface 101B can be a curved surface with a greater degree of curvature than the first surface 101A. The curvatures, i.e., the degrees of curvatures, of the first surface 101A and the second surface 101B are different. Further optionally, the support back plate 101 in the form of the first surface 101A can be understood as the original state of the display device 000 when the hinge assembly 1011 has not received a bending command, and the support back plate 101 in the form of the second surface 101B can be understood as the state after the sensor 102 in the display device 000 senses the user's position and the hinge assembly 1011 receives a bending command and changes its curvature.

[0081] Optional, such as Figure 1 , Figures 8-10 , Figure 15 and Figure 16 As shown, Figure 15 yes Figure 7 and Figure 8 The diagram shown is a structural schematic of the display device in its first operating mode. Figure 16 yes Figure 7 and Figure 8 The diagram shown illustrates the structure of the display device in its second operating mode. In this embodiment, the display device 000 includes a first operating mode and a second operating mode; as shown... Figure 15 As shown, in the first working mode, the omnidirectional structure 30 controls the light-emitting surface 10A of the flexible display module 10 to rotate to the first region P1, and the hinge assembly 1011 controls the supporting back plate 101 to present the first surface 101A, as shown. Figure 16As shown, in the second working mode, the omnidirectional structure 30 controls the light-emitting surface 10A of the flexible display module 10 to turn to the second region P2, and the hinge assembly 1011 controls the supporting back plate 101 to present the second surface 101B. The positions of the first region P1 and the second region P2 are different, and the curvatures of the first surface 101A and the second surface 101B are different. Further optionally, the first region P1 can be understood as the original orientation region of the display device 000 in its original state, that is, when the omnidirectional structure 30 has not received a rotation command, and the supporting back plate 101 presenting the first surface 101A is the original orientation region of the display device 000 in its original state, that is, when the hinge assembly 1011... The original state when no bending command is received, the second area P2 can be understood as the area where the sensor 102 in the display device 000 senses the user's position, the area where the universal structure 30 faces after receiving the rotation command, the second surface 101B of the support back plate 101 is the state after the sensor 102 in the display device 000 senses the user's position, and the state after the hinge assembly 1011 further bends and changes its curvature after receiving the bending command, so that the universal structure 30 and the hinge assembly 1011 can jointly adjust to achieve the best screen viewing angle for the user, thereby improving the safety of use and the display effect.

[0082] In some alternative embodiments, please refer to the references. Figure 1 , Figure 5 , Figure 6 and Figure 17 , Figure 17 yes Figure 5 A schematic diagram of the planar structure of the supporting back plate (it should be understood that this diagram is for the purpose of clearly illustrating the structure of this embodiment). Figure 17 (Transparency fill has been applied). In this embodiment, the hinge assembly 1011 includes multiple hinges 10111 arranged along the first direction X. The hinges 10111 include multiple links 10111A that are interconnected in the second direction Y. The second direction Y is the extension direction of the central axis around which the hinge assembly 1011 bends, and the first direction X intersects with the second direction Y. Figure 17 The example below illustrates this by taking the first direction X and the second direction Y as being perpendicular to each other.

[0083] This embodiment explains that the hinge assembly 1011 included in the support back plate 101 of the display device 000 can be configured such that the hinge assembly 1011 includes multiple hinges 10111 arranged along the first direction X. The multiple hinges 10111 arranged along the first direction X can be connected to each other through the connecting part 1011L. Each hinge 10111 can be provided with multiple links 10111A that are connected to each other in the second direction Y. When the hinge assembly 1011 needs to bend around the central axis when bending in the second direction Y, the connecting part 1011L can be controlled by the second motor assembly 402 to drive the two adjacent hinges 10111 to form different angles, thereby causing the hinge assembly 1011 to bend around the central axis when bending in the second direction Y, thus realizing the bending control of the support back plate 101.

[0084] Optional, please refer to the reference. Figure 1 , Figure 5 , Figure 6 and Figure 18 , Figure 18 yes Figure 5 Another planar structural diagram of the supporting back plate (it should be understood that this diagram is for the purpose of clearly illustrating the structure of this embodiment). Figure 18 (Transparency filling is performed in the middle). In this embodiment, the orthographic projection of the hinge assembly 1011 on the light-emitting surface 10A of the flexible display module 10 can cover the entire area where the flexible display module 10 is located. That is, the curvature of the flexible display module 10 can be controlled by the hinge assembly 1011. Not only in the middle area of ​​the flexible display module 10, but also on both sides of the flexible display module 10 in the first direction X, the curvature can be changed by the hinge assembly 1011 to flexibly control the bending of both sides of the flexible display module 10 in the first direction X, which is beneficial to ensure the all-round bending of the flexible display module 10.

[0085] It is understood that this embodiment does not elaborate on the specific connection structure of the hinge assembly 1011 in the display device 000. In specific implementation, it can be understood based on the hinge structure that can change the curvature of the flexible display module in related technologies.

[0086] It should be noted that the above-described embodiments of this example... Figures 5-10 The diagram only illustrates one bending state of the support back plate 101 controlled by the hinge assembly 1011. In actual implementation, the support back plate 101 drives the flexible display module 10 to bend and exhibit structures with different bending curvatures, including but not limited to this, such as... Figure 19 As shown, Figure 19 yes Figure 8 and Figure 9The diagram shows another example of the display device applied to an in-vehicle display system. The hinge assembly 1011 can also control only the edge region of the flexible display module 10 on the side away from the driver M in the first direction X to create a shading effect on that side, which is beneficial for privacy protection; or as... Figure 20 As shown, Figure 20 yes Figure 8 and Figure 9 The diagram shows another effect of the display device applied to an in-vehicle display system. The hinge assembly 1011 can also control the flexible display module 10 to bend on both sides of the edge region in the first direction X, so as to form a blocking effect on the ambient light when the driver M views the light-emitting surface 10A of the flexible display module 10, which is beneficial to improving the display contrast.

[0087] In some alternative embodiments, please refer to the references. Figure 1 , Figure 2 , Figure 4 and Figure 21 , Figure 21 yes Figure 2 A schematic diagram of another electrical connection structure between the sensor and the universal structure. In this embodiment, the multiple sensor 102 include a sound recognition sensor 1021. The sound recognition sensor 1021 identifies the target area P0 where the user (such as driver M) is located. The universal structure 30 controls the light-emitting surface 10A of the flexible display module 10 to turn towards the target area P0.

[0088] Optionally, the multiple sensor devices 102 may also include a face recognition sensor 1022 or an eye recognition sensor 1023; in the target area P0, the face recognition sensor 1022 or the eye recognition sensor 1023 identifies the first position P01 of the user (such as driver M), and the omnidirectional structure 30 controls the turning of the light-emitting surface 10A of the flexible display module 10 to the first position P01. It can be understood that the target area P0 includes the first position P01, and the target area P0 can be understood as... Figure 12 The second region P2 in the diagram refers to the region where the user is located.

[0089] This embodiment explains that among the multiple sensor components 102 included in the flexible display module 10, there may be a voice recognition sensor 1021, a face recognition sensor 1022, or an eye recognition sensor 1023. During the operation of the display device 000, when the user needs to perform human-computer interaction, the user (such as driver M) can be identified in the target area P0 by the voice recognition sensor 1021. The first motor assembly 401 controls the light-emitting surface 10A of the flexible display module 10 to first turn towards the target area P0 through the universal structure 30, which helps to reduce the light emission surface 10A of the flexible display module 10. The power consumption of the display device 000 is then used; then the face recognition sensor 1022 or the eye recognition sensor 1023 is activated, and in the target area P0, the face recognition sensor 1022 or the eye recognition sensor 1023 identifies the accurate first position P01 of the user (such as the driver M). The first motor assembly 401 then controls the light-emitting surface 10A of the flexible display module 10 to turn to the first position P01 through the universal structure 30. This helps to reduce power consumption while accurately sensing the first position P01 of the user, which helps to improve the accuracy of screen turning.

[0090] It is understood that in this embodiment, the sound recognition sensor 1021, which includes multiple sensors 102, can receive sound sources through a microphone and use methods such as human-like binaural sound source localization, time-difference-based sound source localization, and sound pressure amplitude ratio-based localization (the above various sound source localization methods can be understood by referring to the descriptions in related technologies, which will not be elaborated here in this embodiment) to sense the target area P0 where the user is located; the face recognition sensor 1022 or eye recognition sensor 1023, which includes multiple sensors 102, can be a camera, such as an infrared camera, which can track heat sources and identify the first position P01 where the face or eyes are located, so as to accurately sense the user's position and facilitate the accurate turning of the light-emitting surface 10A of the flexible display module 10. In this embodiment, the type of use of the sound recognition sensor 1021, face recognition sensor 1022, or eye recognition sensor 1023 is not specifically limited. In specific implementation, it can be selected and set according to actual needs.

[0091] In some alternative embodiments, please refer to the references. Figure 1 , Figure 8 , Figure 10 , Figure 13 , Figure 14 and Figure 22 , Figure 22 yes Figure 8 A schematic diagram of another electrical connection structure between the sensor and the hinge assembly. In this embodiment, the plurality of sensor 102 includes an ambient brightness recognition sensor 1024.

[0092] Ambient light sensor 1024 detects that the ambient light is below a first threshold, and hinge assembly 1011 controls the support back plate 101 to be planar (e.g., Figure 13 (as shown);

[0093] Ambient light sensor 1024 detects that the ambient light intensity is higher than a first threshold, and hinge assembly 1011 controls the support back plate 101 to be curved (e.g., Figure 14 (As shown).

[0094] This embodiment explains that among the multiple sensors 102 included in the flexible display module 10, there may be an ambient light recognition sensor 1024. When the ambient light recognition sensor 1024 detects that the ambient light brightness is lower than a first threshold (it can be understood that the first threshold can be a preset ambient light brightness value of the display device 000; when the measured ambient light brightness is higher than the first threshold, it may cause the display contrast to be too low, affecting the viewing effect), the hinge assembly 1011 controls the support back plate 101 to be planar. That is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is lower than the preset first threshold, it is not enough to affect the display contrast and viewing effect. At this time, the hinge assembly 1011 does not move, and there is no need for the hinge assembly 1011 to control the surface curvature of the support back plate 101 to change, so it can be in its original planar state (e.g., Figure 13 (As shown). When the ambient light recognition sensor 1024 detects that the ambient light brightness is higher than the first threshold, the hinge assembly 1011 controls the support back plate 101 to be curved. That is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is higher than the preset first threshold, which may cause the display contrast to be too low and affect the viewing effect, the hinge assembly 1011 can control the surface curvature of the support back plate 101 to change, so that the support back plate 101 drives the light-emitting surface 10A of the flexible display module 10 to be curved (as shown). Figure 14 As shown, the light-emitting surface 10A of the curved flexible display module 10 can block ambient light and improve the display contrast, thus providing viewers with a better viewing experience.

[0095] Optional, please refer to the reference. Figure 1 , Figure 8 , Figure 10 and Figure 22In this embodiment, the ambient light sensor 1024 can detect ambient light brightness after determining the user's first position P01. That is, during the operation of the display device 000, when the user needs to perform human-computer interaction, the sound recognition sensor 1021 can first identify the target area P0 where the user (such as driver M) is located. The omnidirectional structure 30 controls the light-emitting surface 10A of the flexible display module 10 to first turn towards the target area P0. Then, the face recognition sensor 1022 or the eye recognition sensor 1023 is activated, and the light is emitted in the target area P0. In the process, the face recognition sensor 1022 or the eye recognition sensor 1023 identifies the accurate first position P01 of the user (such as the driver M). The first motor assembly 401 then controls the light-emitting surface 10A of the flexible display module 10 to turn to the first position P01 through the universal structure 30. Then, the ambient light sensor 1024 is activated to identify the ambient light brightness. If necessary, the curvature is changed through the hinge assembly 1011 to block the ambient light. This helps to reduce power consumption, improve the accuracy of screen turning, and ensure the user's viewing experience.

[0096] It is understood that the ambient brightness recognition sensor 1024 included in the multiple sensors 102 in this embodiment can be a light sensor to sense the brightness value of the environment. This embodiment does not specifically limit the type of ambient brightness recognition sensor 1024. In specific implementation, it can be selected and set according to actual needs.

[0097] In some alternative embodiments, please refer to the references. Figure 23 and Figure 24 , Figure 23 This is a schematic diagram of another planar structure of the display device provided in an embodiment of the present invention. Figure 24 yes Figure 23 A side view of a display device (it is understood that this is for the purpose of clearly illustrating the structure of this embodiment). Figure 23 (Transparency filling is performed in the middle). In this embodiment, multiple sensor devices 102 are disposed on one side of the light-emitting surface 10A of the flexible display module 10, and multiple sensor devices 102 are located in the non-display area NA of the flexible display module 10.

[0098] This embodiment explains that the multiple sensor elements 102 included in the flexible display module 10 can be disposed on one side of the light-emitting surface 10A of the flexible display module 10. When the multiple sensor elements 102 include a face recognition sensor 1022, an eye recognition sensor 1023, or an ambient brightness recognition sensor 1024, they can be unobstructed by the structure of the flexible display module 10 itself, which helps to ensure the sensing effect of the sensor elements 102. Furthermore, when the multiple sensor elements 102 are disposed on one side of the light-emitting surface 10A of the flexible display module 10, the multiple sensor elements 102 can be located in the non-display area NA of the flexible display module 10, which can prevent the placement of the sensor elements 102 in the flexible display module 10 from affecting the normal display of the display area AA of the flexible display module 10, thereby improving the user's viewing experience satisfaction.

[0099] It is understood that in this embodiment Figure 23 and Figure 24 This example uses four sensor elements 102 as an example. In actual implementation, the number of sensor elements 102 may include, but is not limited to, this number and can be set according to the actual sensing requirements of the display device 000. Figure 23 and Figure 24 This example illustrates the situation by using multiple sensor devices 102 located in the corner of the non-display area NA of the flexible display module 10 as an example, in order to avoid the scanning drive circuit, test circuit and other structures that may be included in the non-display area NA. In actual implementation, the placement of the sensor devices 102 includes, but is not limited to, this example. They can also be placed in other non-display area NA positions of the flexible display module 10, as long as the sensing function is guaranteed and the driving display function of the flexible display module 10 itself is not affected. This embodiment does not limit this.

[0100] In some alternative embodiments, please refer to the references. Figure 25 and Figure 26 , Figure 25 This is a schematic diagram of another planar structure of the display device provided in an embodiment of the present invention. Figure 26 yes Figure 25 A side view of a display device (it is understood that this is for the purpose of clearly illustrating the structure of this embodiment). Figure 25 (Transparency filling is applied in the middle). In this embodiment, the multiple sensor devices 102 include a first sensor device 1021 and a second sensor device 1022. The first sensor device 1021 includes any one or more of a sound recognition sensor and an ambient brightness recognition sensor. The second sensor device 1022 includes any one or more of a face recognition sensor and an eye recognition sensor.

[0101] The first sensor 1021 is disposed on one side of the backlight surface 10B of the flexible display module 10 or at the edge 10L of the flexible display module 10; the second sensor 1022 is disposed on one side of the light-emitting surface 10A of the flexible display module 10.

[0102] This embodiment explains that the multiple sensor elements 102 included in the flexible display module 10 can be partially disposed on one side of the light-emitting surface 10A of the flexible display module 10, and partially disposed on the non-light-emitting surface of the flexible display module 10. Specifically, the multiple sensor elements 102 can include a first sensor element 1021 and a second sensor element 1022. The first sensor element 1021 can be any one or more of a sound recognition sensor and an ambient brightness recognition sensor, and the second sensor element 1022 can be any one or more of a face recognition sensor and an eye recognition sensor. Therefore, the second sensor element 1022 that needs to collect user face or eye information can be disposed on one side of the light-emitting surface 10A of the flexible display module 10 (i.e., the side facing the user), so that on the light-emitting surface 10A of the flexible display module 10... The second sensor 1022 on one side of the flexible display module 10 can promptly and accurately sense the user's position. Other first sensors 1021, such as sound recognition sensors and ambient brightness recognition sensors, which do not require collecting information about the user's face or eyes, can be set on the backlight surface 10B of the flexible display module 10 or at the edge 10L of the flexible display module 10 (which can be understood as the side edge of the flexible display module 10). This allows the sound recognition sensor to sense the user's sound source location and the ambient brightness recognition sensor to sense the brightness of the display device 000 in the environment in which it is used. It also avoids having too many sensors 102 on the light-emitting surface 10A of the flexible display module 10, which would affect the light emission display effect. Furthermore, it provides more layout space for the non-display area NA of the flexible display module 10, saving the area of ​​the bezel area.

[0103] In some alternative embodiments, please refer to the references. Figure 17 , Figure 18 , Figure 27 and Figure 28 , Figure 27 This is a schematic diagram of another planar structure of the display device provided in an embodiment of the present invention. Figure 28 yes Figure 27 The image shown is a rendering of a display device used in an in-vehicle display system. Figure 29 yes Figure 27 The diagram shown illustrates another possible application of the display device in an in-vehicle display system (it is understood that this diagram is used to clearly illustrate the structure of this embodiment). Figure 27 Transparency fill was applied to the middle. Figure 28 and Figure 29 The display device shown in the diagram can also be understood. Figure 27(Top side view of the display device in the figure) In this embodiment, along the first direction X, the flexible display module 10 includes a main display area 10Z and an edge area 10Y located on at least one side of the main display area 10Z; wherein, the first direction X intersects or is perpendicular to the extension direction of the central axis around which the hinge assembly 1011 bends (i.e., the second direction Y shown in the figure).

[0104] Under the control of the hinge assembly 1011, the curvature of at least one edge area 10Y of the flexible display module 10 is greater than or equal to the curvature of the main display area 10Z of the flexible display module 10.

[0105] This embodiment explains that the display device 000, under the control of the hinge assembly 1011, can cause the support back plate 101 to bend, thereby causing the curvature of at least one edge area 10Y of the flexible display module 10 to be greater than or equal to the curvature of the main display area 10Z. The main display area 10Z and the edge area 10Y of the flexible display module 10 are arranged in the first direction X, with the edge area 10Y located on at least one side of the main display area 10Z. When the illustrated display device is applied to the central control screen area of ​​an in-vehicle display system, the curvature of the flexible display module 10 of at least one edge area 10Y in the first direction X can be equal to the curvature of the flexible display module 10 of the main display area 10Z (e.g., ...). Figure 28 As shown), the edge area 10Y has the same degree of curvature as the main display area 10Z. In this case, the edge area 10Y of the flexible display module 10 in the display device 000 does not block ambient light. Optionally, the display device 000 includes a display area AA and a non-display area NA surrounding the display area AA. In this case, the edge area 10Y in this embodiment can also be displayed, that is, the edge area 10Y can be used as the display area AA. When the edge area 10Y does not block ambient light, it can be used together with the main display area 10Z as the display area AA of the flexible display module 10, which is beneficial to expanding the display area of ​​the display device 000. Or, as Figure 27 and Figure 29 As shown, through the control of the hinge assembly 1011, the curvature of the flexible display module 10 in at least one edge region 10Y in the first direction X can also be made greater than the curvature of the flexible display module 10 in the main display region 10Z (e.g., Figure 29 As shown in the diagram, the edge region 10Y has a large degree of bending, which serves to block ambient light and also protects privacy after the flexible display module 10 in the edge region 10Y is bent. Optionally, the display device 000 includes a display area AA and a non-display area NA surrounding the display area AA, with the edge region 10Y located in the non-display area NA. In this embodiment, the edge region 10Y can be the non-display area NA of the flexible display module 10, thus avoiding the impact of the large bending degree of the edge region 10Y on the display effect.

[0106] Optional, such as Figure 27 and Figure 29 As shown, the edge area 10Y includes a bending area 10Y1 and a light-shielding area 10Y2 located on the side of the bending area 10Y1 away from the main display area 10Z. The light-shielding area 10Y2 is located on one side of the light-emitting surface of the main display area 10Z. When the hinge assembly 1011 drives the flexible display module 10 to bend in the bending area 10Y1, the light-shielding area 10Y2 bends to the side of the light-emitting surface of the main display area 10Z through the bending of the bending area 10Y1. Optionally, after bending, the angle between the flexible display module 10 of the main display area 10Z and the flexible display module 10 of the light-shielding area 10Y2 can be between 80° and 100°. The light-shielding area 10Y2 can block the light from the main display area 10Z over a wide viewing angle range, better blocking the viewing angle of people in other positions and ambient light interference, thus playing a good role in blocking ambient light and protecting privacy.

[0107] It is understood that the flexible display module 10 within the edge region 10Y of this embodiment can be used as a display in one case and as a non-display in another. This embodiment does not elaborate on the specific display control method for the edge region 10Y. The flexible display module 10 within the edge region 10Y can include sub-pixels that can emit light under the drive of a drive signal. When the flexible display module 10 within the edge region 10Y is used as a display, the sub-pixels can be driven to emit light normally. When the flexible display module 10 within the edge region 10Y is used as a non-display, no drive signal is provided to the sub-pixels in this range. The sub-pixels within the edge region 10Y can be used as virtual sub-pixels to realize that the flexible display module 10 within the edge region 10Y does not display an image, but only plays a role in blocking ambient light and protecting privacy, and also helps to reduce the power consumption of the module.

Figure 30Transparency fill was applied to the middle. Figure 33 and Figure 34 The display device shown in the diagram can also be understood. Figure 30 (Top side view of the display device in the image). In this embodiment, the display device 000 also includes a scroll 50. Along the first direction X, the display device 000 includes an extended portion 01 and a non-extended portion 02 disposed adjacently. The extended portion 01 is located in the edge region 10Y. The non-extended portion 02 includes a winding end 02A, which is located on the side of the non-extended portion 02 away from the extended portion 01.

[0109] The winding end 02A is fixed to the reel 50, and at least a portion of the non-extended portion 02 is wound on the reel 50;

[0110] The scroll 50 is electrically connected to the third motor assembly 403, which is electrically connected to at least one sensor element 102. Optionally, the third motor assembly 403 can be mounted on one side of the backlight surface 10B of the flexible display module 10 (not shown in the figure), or it can be mounted on the end of the scroll 50 (not shown in the figure), or it can be mounted inside the bracket 20 (e.g., Figure 31 As shown, in order to avoid affecting the light emission effect of the display device 000, it is only necessary to ensure that the third motor assembly 403 is electrically connected to the sensor 102 and the scroll 50 respectively.

[0111] This embodiment explains that the flexible display module 10 included in the display device 000 can be a rollable screen. Specifically, the display device 000 includes a scroll 50, and includes an extension portion 01 and a non-extension portion 02 adjacently arranged in a first direction X. The first direction X can be understood as a direction perpendicular to the extension direction of the central axis around which the hinge assembly 1011 bends (i.e., the second direction Y shown in the figure). The extension portion 01 is located in the edge region 10Y of the flexible display module 10, and the non-extension portion 02 can be understood as a region in the first direction X away from the edge region 10Y. The winding end 02A of the non-extension portion 02 is located away from the extension portion 01. On one side, and fixed to the scroll 50, the winding end 02A of the non-extended portion 02 is fixed to the scroll 50 so that at least part of the non-extended portion 02 is wound on the scroll 50. The number of turns of the non-extended portion 02 wound on the scroll 50 can be changed by rotating the scroll 50, thereby controlling the extension portion 01 of the display device 000 to extend. Through the bending engagement of the hinge assembly 1011, when the ambient light detected by the sensor 102 is not high, the hinge assembly 1011 can control the junction between the extended portion 01 and the non-extended portion 02 to remain flat or have a small degree of bending. The structure between the extended portion 01 and the non-extended portion 02 can still be flat or similarly flat (e.g., Figure 33As shown), at this time, the extended portion 01 and the non-extended portion 02 located in the edge area 10Y can both be used as display areas. Optionally, such as Figures 30-32 , Figure 33 As shown, the display device 000 includes a first state at this time. In the first state, both the extended portion 01 and the non-extended portion 02 serve as the display area AA of the display device 000, which is beneficial for expanding the display area of ​​the display device 000. When the ambient light intensity sensed by the sensor 102 is high, the hinge assembly 1011 can control the bending of the junction between the extended portion 01 and the non-extended portion 02, forming an angle between the extended portion 01 and the non-extended portion 02 (e.g., Figure 34 As shown), the extension 01 can also form a brim-like shielding structure in the edge area 10Y to block ambient light and protect privacy. Optionally, such as Figures 30-32 , Figure 34 As shown, the display device 000 includes a second state at this time. In the second state, the non-extended portion 02 serves as the display area AA of the display device 000, the extended portion 01 serves as the non-display area NA of the display device 000, and the extended portion 01 located in the edge area 10Y can be used as a non-display area.

[0112] It should be noted that when the flexible display module 10 in this embodiment is a rollable screen including a scroll 50, the extension range of the extended portion 01 can be controlled by controlling the number of turns of the non-extended portion 02 on the scroll 50. When the user does not need to protect privacy or block ambient light, the number of turns on the scroll 50 can be greater, and the extended portion 01 does not need to extend or bend. However, when the user needs to protect privacy and block the wide-viewing-angle light of the flexible display module 10 or block ambient light, the number of turns on the scroll 50 can be reduced, allowing more of the non-extended portion 02 to be released from the scroll 50, the extended portion 01 to extend a larger range, and the extended portion 01 to bend under the control of the hinge assembly 1011, thus blocking the wide-viewing-angle light of the light-emitting surface of the flexible display module 10 and blocking ambient light. After the extension part 01 changes from a non-extended state to an extended state that acts as a shield, the area of ​​the display area of ​​the flexible display module 10 can be understood as unchanged before and after the change. Only the position of the display area on the flexible display module 10 changes. That is, the more the extension part 01 extends, the closer the position of the display area on the flexible display module 10 moves to the winding end 02A of the non-extended part 02.

[0113] It is understood that when the display device 000 of this embodiment is applied to the central control screen area J1 of the vehicle display system, it can be used as follows: Figure 34 As shown, the extension 01 forms a bent brim-like shielding structure on the side away from the driver M (i.e., the right side of the central control screen area J1) to block ambient light from non-driver positions and to block the view of people other than the driver, thus protecting the privacy of the driver M, i.e., the user.

[0114] Or in some other alternative embodiments, such as Figure 35 As shown, Figure 35 yes Figure 31 and Figure 32 The diagram shown illustrates another application of the display device in an in-vehicle display system. Figure 35 This can be understood as... Figure 34 The flexible display module 10 in the figure is rotated counterclockwise by the universal structure 30 to obtain a side view, so that the extension 01 is rotated to the top of the central control screen area to block the ambient light passing through the windshield. Specifically, when the display device 000 is applied to the central control screen area of ​​the vehicle display system, the direction of the universal structure 30 can be changed by the first motor assembly 401, so that the bent extension 01 is rotated to the top of the central control screen area J1 (which can be understood as...). Figure 34 The flexible display module 10 rotates via the universal structure 30, causing the extension 01 to rotate to the top of the central control screen area J1, and the side where the scroll 50 is located to rotate to the bottom of the central control screen area J1, as shown. Figure 35 As shown, ambient light is blocked at the top of the central control screen area J1 (e.g., Figure 35 The sunlight shown in the diagram serves to enhance display contrast and improve display quality when the driver M views the display screen of the flexible display module 10 in excessively bright ambient light.

[0115] Optional, such as Figure 36 As shown, Figure 36 yes Figure 31The diagram illustrates another electrical connection structure between the sensor components and the universal joint 30, hinge assembly, and scroll 50. Multiple sensor components 102 include a voice recognition sensor 1021, a face recognition sensor 1022, or an eye recognition sensor 1023. These sensors are electrically connected to the universal joint 30 via a first motor assembly 401. The sensor components 102 also include an ambient light recognition sensor 1024, which is electrically connected to the hinge assembly 1011 via a second motor assembly 402. In this embodiment, the third motor assembly 403, electrically connected to the scroll 50, can be a rotary motor. The rotary motor can also be electrically connected to the ambient light recognition sensor 1024. When the ambient light recognition sensor detects an ambient light level below a certain threshold... The first threshold (understandably, the first threshold can be the ambient light brightness value preset by the display device 000. When the measured ambient light brightness is higher than the first threshold, it may cause the display contrast to be too low, affecting the viewing effect). The rotary motor can control the number of turns of the non-extended portion 02 wound by the scroll 50 to be more. In conjunction with the hinge assembly 1011, the support back plate 101 is controlled to be in a planar or similar planar shape. That is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is lower than the preset first threshold, it will not affect the display contrast and viewing effect. At this time, the hinge assembly 1011 does not move. There is no need for the hinge assembly 1011 to control the surface curvature of the support back plate 101 to change at the junction of the extended portion 01 and the non-extended portion 02. It can be in the original planar or similar planar shape. When the ambient light recognition sensor 1024 detects that the ambient light brightness is higher than a first threshold, the rotary motor can control the number of turns of the non-extended portion 02 wound by the scroll 50 to reduce the number of turns, so that more of the non-extended portion 02 can extend from the scroll. The hinge assembly 1011 controls the surface curvature of the support back plate 101 at the junction of the extended portion 01 and the non-extended portion 02. That is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is higher than the preset first threshold, which may cause the display contrast to be too low and affect the viewing effect, the hinge assembly 1011 can be used to control the junction of the extended portion 01 and the non-extended portion 02 to be bent, so that the support back plate 101 drives the flexible display module 10 to be bent at the junction of the extended portion 01 and the non-extended portion 02. More of the non-extended portion 02 can be extended for display by rotating the scroll 50. The bent extended portion 02 can block the ambient light, improve the display contrast, provide a better viewing effect for the viewer, and also protect privacy.

[0116] Optional, such as Figure 33As shown, in this embodiment, when the ambient light intensity sensed by the sensor 102 is not high, the hinge assembly 1011 controls the junction between the extended portion 01 and the non-extended portion 02 to be not bent or to a small degree of bending. The extended portion 01 and the non-extended portion 02 can still be a flat or similarly flat structure. This allows the display device 000 in the first state to have an angle α formed between the extended portion 01 and the non-extended portion 02 controlled by the hinge assembly 1011, where 150°≤α≤180°. This enables both the extended portion 01 and the non-extended portion 02 to be used as the display area AA of the display device 000 in the first state, which is beneficial for expanding the display area of ​​the display device 000.

[0117] Optional, such as Figure 34 As shown, in this embodiment, when the ambient light brightness sensed by the sensor 102 is high, the hinge assembly 1011 controls the junction of the extended portion 01 and the non-extended portion 02 to have a large bend (the extended portion 01 and the non-extended portion 02 form an angle). This allows the display device 000 in the second state to have an angle β formed between the extended portion 01 and the non-extended portion 02 controlled by the hinge assembly 1011, where 80°≤β≤100°. This enables the extended portion 01 to form a brim-like shielding structure in the edge area 10Y of the second state, which shields ambient light and protects privacy.

[0118] In some optional implementations, please refer to the reference. Figures 30-36 and Figure 37 , Figure 37 yes Figure 31 and Figure 32 The diagram shown illustrates another possible application of the display device in an in-vehicle display system (it is understood that this diagram is used to clearly illustrate the structure of this embodiment). Figure 37 The display device shown in the diagram can also be understood. Figure 30 (Top side view of the display device in the image). In this embodiment, the display device 000 is in a second state, as shown in the image. Figure 34 As shown, the ambient light intensity sensed by the ambient light recognition sensor 1024 is A1, and the width of the extension 01 is B1; Figure 37 As shown, the ambient light brightness sensed by the ambient light recognition sensor 1024 is A2, and the width of the extension 01 is B2; wherein, A2 > A1, B2 > B1.

[0119] This embodiment explains that the width of the extension 01 located in the edge region 10Y can change with the ambient light brightness. When the ambient light brightness measured by the ambient light recognition sensor 1024 is higher than a preset first threshold, which may cause the display contrast to be too low and affect the viewing effect, if the ambient light brightness sensed by the ambient light recognition sensor 1024 is A1, the corresponding third motor assembly 403 can control the number of turns of the non-extension 02 wound on the scroll 50 to be more, so that the width of the extension 01 that plays the role of blocking ambient light is B1. If the ambient light brightness sensed by the ambient light recognition sensor 1024 is A2, A2>A1, that is, the ambient light brightness becomes stronger, then... The corresponding third motor assembly 403 can control the number of turns of the non-extended portion 02 wound on the scroll 50 to be less, so that more of the non-extended portion 02 can be wound outside the scroll 50. As a result, the area of ​​the extended portion 01 at the end away from the non-extended portion 02 can extend further. That is, the width of the extended portion 01 is B2, B2>B1. This means that the stronger the ambient light detected by the ambient light recognition sensor 1024, the wider the width of the extended portion 01 that plays a blocking role. This allows for greater blocking of light from the large viewing angle range of the flexible display module 10 emitting light surface of the non-extended portion 02, and greater blocking of the viewing angle and ambient light interference of people in other positions, thus playing a better role in blocking ambient light and protecting privacy.

[0120] In some alternative embodiments, please refer to the references. Figures 1-10 , Figure 38 , Figure 38 This is a flowchart of a control method for a display device provided in an embodiment of the present invention. The control method for the display device provided in this embodiment can be the display device 000 in the above embodiments; the control method of this embodiment includes:

[0121] Sensor 102 senses the user's location;

[0122] The first motor assembly 401 controls the rotation of the universal structure 30, so that the light-emitting surface 10A of the flexible display module 10 faces the user; and / or,

[0123] The second motor assembly 402 controls the hinge assembly 1011 to bend, adjusting the curvature of the flexible display module 10.

[0124] This embodiment explains how the control method for the display device can be used to control the above-mentioned... Figure 1 , Figure 2 , Figure 3The display device shown has a sensor 102 that senses the user's position, and a first motor assembly 401 that controls the rotation of the omnidirectional structure 30. The light-emitting surface 10A of the flexible display module 10 faces the user. Feedback information sensed by the sensor 102, such as the user's position feedback and sound feedback, is transmitted to the first motor assembly 401. The first motor assembly 401 calculates and transmits kinetic energy to the omnidirectional structure 30, causing the omnidirectional structure 30 to change its direction. The first motor assembly 401 controls the omnidirectional structure 30, thereby controlling the direction of the supporting back plate 101, which in turn changes the direction of the flexible display module 10. This ensures that the light-emitting surface 10A of the flexible display module 10 faces the user as much as possible, achieving a better viewing angle for the user. When the display device 000 is applied to the central control screen area of ​​the vehicle display system, even if the display device 000 is far from the driver's position, the light-emitting surface 10A of the flexible display module 10 can be turned toward the driver in a timely manner by controlling the first motor assembly 401 and the universal structure 30 according to the driver's position. Thus, when interacting with the vehicle, the driver can see the display screen of the light-emitting surface 10A of the flexible display module 10 without turning his head. When necessary, the driver can operate the screen. During the vehicle's operation, the driver's eyes can be kept away from the driving direction, which is conducive to improving driving safety.

[0125] This embodiment explains that the control method for the display device can also be used to control the above-mentioned... Figure 4 , Figure 5 , Figure 6The display device shown includes a sensor 102 that senses the user's position, and a second motor assembly 402 that controls the hinge assembly 1011 to bend, adjusting the curvature of the flexible display module 10. Feedback information sensed by the sensor 102, such as user position feedback and sound feedback, is transmitted to the second motor assembly 402. The second motor assembly 402 calculates the kinetic energy transmitted to the hinge assembly 1011, causing the hinge assembly 1011 to change its degree of curvature, such as changing from a planar shape to a curved shape, or from a curved shape with a smaller curvature to a curved shape with a larger curvature. The second motor assembly 402 controls the hinge assembly 1011, thereby controlling the degree of curvature of the support back plate 101, thus changing the degree of curvature of the flexible display module 10. By setting the light-emitting surface 10A of the flexible display module 10 to a curved shape, the light-emitting surface 10A of the flexible display module 10 is made to face the user as much as possible, achieving a better viewing angle for the user. When the display device 000 is applied to the central control screen area of ​​the vehicle display system, even if the display device 000 is far from the driver's position, it can be controlled by the second motor assembly 402 and the hinge assembly 1011 to make the light-emitting surface 10A of the flexible display module 10 curved and facing the driver in a timely manner according to the driver's position. Thus, when interacting with the vehicle, the driver can see the display screen of the light-emitting surface 10A of the flexible display module 10 without turning his head. When necessary, the driver can operate the screen. During the vehicle's operation, the driver's eyes can be kept away from the driving direction, which helps to improve driving safety.

[0126] This embodiment explains that the control method for the display device can also be used to control the above-mentioned... Figure 7 , Figure 8 , Figure 9The display device shown includes a sensor 102 that senses the user's position, a first motor assembly 401 that controls the rotation of the omnidirectional structure 30 so that the light-emitting surface 10A of the flexible display module 10 faces the user, and a second motor assembly 402 that controls the hinge assembly 1011 to bend, adjusting the curvature of the flexible display module 10. Feedback information sensed by the sensor 102, such as user position feedback and sound feedback, is transmitted to the first motor assembly 401. The first motor assembly 401 calculates and transmits kinetic energy to the omnidirectional structure 30, causing the omnidirectional structure 30 to change its direction. By controlling the omnidirectional structure 30 through the first motor assembly 401, the rotation of the support backplate 101 is controlled, thereby changing the rotation of the flexible display module 10. Simultaneously, the feedback information sensed by the sensor 102... Information such as user position feedback and sound feedback can also be transmitted to the second motor assembly 402. After the second motor assembly 402 calculates and transmits the kinetic energy to the hinge assembly 1011, it causes the hinge assembly 1011 to change its curvature, such as changing from a planar shape to a curved shape, or from a curved shape with a smaller curvature to a curved shape with a larger curvature. In order to control the hinge assembly 1011 through the second motor assembly 402, while the direction of the light-emitting surface 10A of the flexible display module 10 changes, the curvature of the support back plate 101 is further controlled to change the curvature of the flexible display module 10. By setting the light-emitting surface 10A of the flexible display module 10 to a curved shape, the light-emitting surface 10A of the flexible display module 10 is further turned towards the user, so as to achieve a better viewing angle for the user. When the display device 000 is applied to the central control screen area of ​​the vehicle display system, even if the display device 000 is far from the driver's position, the light-emitting surface 10A of the flexible display module 10 can be directed to face the driver at a better angle through the control of the first motor assembly 401 and the universal structure 30, the second motor assembly 402 and the hinge assembly 1011, which is conducive to further improving driving safety. It can also block the ambient light within the user's viewing range, which is conducive to improving the contrast when the user views the display device 000, and thus helps the user achieve the best viewing effect.

[0127] Optional, such as Figures 1-4 , Figure 11 , Figure 12 , Figure 39 As shown, Figure 39This is another flowchart of a control method for a display device provided in this embodiment of the invention. In this control method, sensor 102 senses the user's location; first motor assembly 401 controls the rotation of omnidirectional structure 30, so that the light-emitting surface 10A of flexible display module 10 faces the user. This includes: the omnidirectional structure 30 controls the light-emitting surface 10A of flexible display module 10 to initially rotate towards the first region P1; after the sensor senses the user's location in the second region P2, the omnidirectional structure 30 controls the light-emitting surface 10A of flexible display module 10 to rotate towards the second region P2. The positions of the first region P1 and the second region P2 are different. Optionally, the first region P1 can be understood as the original orientation region of display device 000 in its initial state, i.e., when omnidirectional structure 30 has not received a rotation command; the second region P2 can be understood as the region that the sensor 102 in display device 000 senses the user's location, and the omnidirectional structure 30 faces after receiving a rotation command.

[0128] Optional, such as Figures 1-4 , Figure 21 , Figure 40 As shown, Figure 40 This is another flowchart of the control method for the display device provided in this embodiment of the invention. In the control method for the display device provided in this embodiment, the plurality of sensor devices 102 of the display device 000 include at least a face recognition sensor 1022 and a voice recognition sensor 1021.

[0129] The voice recognition sensor 1021 senses the target area P0 where the user is located. Within the target area P0, the face recognition sensor 1022 is activated to determine the first position P01 where the user's face is located. The omnidirectional structure 30 controls the light-emitting surface 10A of the flexible display module 10 to turn to the first position P01.

[0130] This embodiment explains the specific process of sensor 102 sensing the user's location in the control method of the display device. This process may include: among the multiple sensor 102s included in the flexible display module 10, there may be a voice recognition sensor 1021 and a face recognition sensor 1022. During the control of the display device 000, when the user needs to interact with the computer, the voice recognition sensor 1021 can first identify the target area P0 where the user is located. The first motor assembly 401 controls the light-emitting surface 10A of the flexible display module 10 to first turn towards the target area P0 via the universal structure 30, which helps reduce the power consumption of the display device 000. Then, the face recognition sensor 1022 or the eye recognition sensor 1023 is activated. In the target area P0, the face recognition sensor 1022 identifies the accurate first position P01 where the user is located. The first motor assembly 401 then controls the light-emitting surface 10A of the flexible display module 10 to turn towards the first position P01 via the universal structure 30. This helps reduce power consumption while accurately sensing the first position P01 where the user is located, thus improving the accuracy of screen turning.

[0131] Optional, such as Figure 1 , Figures 5-7 , Figure 13 , Figure 14 , Figure 41 As shown, Figure 41 This is another flowchart of a control method for a display device provided in this embodiment of the invention. In this control method, sensor 102 senses the user's position; second motor assembly 402 controls hinge assembly 1011 to bend, adjusting the curvature of flexible display module 10, including:

[0132] The hinge assembly 1011 controls the support back plate 101 to be in its original state as a first surface 101A. The sensor 102 senses the user's position. The hinge assembly 1011 controls the support back plate 101 to be in a second surface 101B, such that the curvature of the second surface 101B is greater than the curvature of the first surface 101A.

[0133] This embodiment explains the specific process by which the sensor 102 senses the user's location in the control method of the display device. It may include: the hinge assembly 1011 controls the original state of the support back plate 101 to be a first surface 101A, which can be a plane or a curved surface; the sensor 102 senses the user's location; the hinge assembly 1011 controls the support back plate 101 to be a second surface 101B, which can be a curved surface with a greater degree of curvature than the first surface 101A; the curvature of the first surface 101A and the degree of curvature of the second surface 101B are different. The first surface 101A of the support back plate 101 can be understood as the original state of the display device 000 when the hinge assembly 1011 has not received a bending command. The second surface 101B of the support back plate 101 can be understood as the state after the sensor 102 in the display device 000 senses the user's position and the hinge assembly 1011 receives a bending command and bends to change its curvature, so that the adjustment of the hinge assembly 1011 can achieve the best screen viewing angle for the user, thereby improving the safety of use and the display effect.

[0134] Optionally, the multiple sensors 102 of the display device 000 include an ambient light recognition sensor 1024; the ambient light recognition sensor 1024 recognizes that the ambient light brightness is lower than a first threshold (understandably, the first threshold can be a preset ambient light brightness value of the display device 000; when the measured ambient light brightness is higher than the first threshold, it may cause the display contrast to be too low, affecting the viewing effect), and the hinge assembly 1011 controls the support back plate 101 to have a first surface 101A. The first surface 101A is planar, that is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is lower than the preset first threshold, it is not enough to affect the display contrast and viewing effect. At this time, the hinge assembly 1011 does not move, and there is no need for the hinge assembly 1011 to control it. The surface curvature of the support back plate 101 is changed; the ambient light recognition sensor 1024 recognizes that the ambient light brightness is higher than a first threshold, and the hinge assembly 1011 controls the support back plate 101 to form a second surface 101B. The second surface 101B is curved. That is, when the ambient light brightness measured by the ambient light recognition sensor 1024 is higher than the preset first threshold, which may cause the display contrast to be too low and affect the viewing effect, the surface curvature of the support back plate 101 can be changed by the hinge assembly 1011, so that the support back plate 101 drives the light-emitting surface 10A of the flexible display module 10 to be curved. The curved light-emitting surface 10A of the flexible display module 10 can block the ambient light and improve the display contrast, so that the viewer can get a better viewing effect.

[0135] In some alternative embodiments, please refer to the references. Figure 22 , Figure 27 , Figure 29 , Figure 42 and Figure 43 , Figure 42 yes Figure 27 The diagram shown illustrates another application of the display device in an in-vehicle display system. Figure 43 This is another flowchart of the control method for a display device provided in this embodiment of the invention. In the control method for a display device provided in this embodiment, the flexible display module 10 includes an intermediate area (the intermediate area can be understood as...). Figure 27 The main display area 10Z in the middle area and the edge areas 10Y located on opposite sides of the middle area;

[0136] Under the control of the hinge assembly 1011, the curvature of at least one edge region 10Y of the flexible display module 10 includes at least a first level (e.g., Figure 29 (as shown) and second gear (as shown) Figure 42 As shown), the curvature of the flexible display module 10 in the edge area 10Y under the first gear is greater than the curvature of the flexible display module 10 in the edge area 10Y under the second gear.

[0137] Sensor device 102 includes at least an ambient light recognition sensor 1024;

[0138] If the ambient light brightness sensed by the ambient light recognition sensor 1024 is C1, then the hinge assembly 1011 controls the curvature of the flexible display module 10 in the edge area 10Y to be in the first position.

[0139] If the ambient light brightness sensed by the ambient light recognition sensor 1024 is C2, then the hinge assembly 1011 controls the curvature of the flexible display module 10 in the edge area 10Y to be in the second position; where C1 > C2.

[0140] This embodiment explains the control method of the display device, in which the curvature of the edge area 10Y of the flexible display module 10 can be set to change with the change of ambient light brightness. That is, under the control of the hinge assembly 1011, the curvature of at least one edge area 10Y of the flexible display module 10 includes at least two different levels: a first level and a second level. Specifically, if the ambient light brightness sensed by the ambient light recognition sensor 1024 is C1, then the hinge assembly 1011 controls the curvature of the edge area 10Y of the flexible display module 10 at the first level. If the ambient light brightness sensed by the ambient light recognition sensor 1024 is C2, and C2 is less than C1, the ambient light brightness is weaker, then the hinge assembly 1011 controls the curvature of the edge area 10Y of the flexible display module 10 at the second level, and the degree of bending is smaller. The brighter the environment, the greater the curvature of the edge area 10Y and the greater the degree of bending, which can make the edge area 10Y block the ambient light as much as possible and improve the display contrast.

Figures 1-4 , Figure 44 and Figure 45 , Figure 44 yes Figure 2 and Figure 3 The diagram shown illustrates another application of the display device in an in-vehicle display system. Figure 45 This is another flowchart of the control method for the display device provided in this embodiment of the invention. In the control method for the display device provided in this embodiment, the operating modes of the control display device 000 include at least a safety mode and a usage mode; in the safety mode, the flexible display module 10 does not work; or, the first motor assembly 401 controls the rotation of the universal structure, so that the light-emitting surface of the flexible display module is away from the user, such as... Figure 44 The driver M is shown in the diagram; as shown in the diagram. Figure 4 As shown, in the usage mode, the first motor assembly 401 controls the rotation of the universal structure 30 so that the light-emitting surface 10A of the flexible display module 10 faces the user.

[0142] This embodiment explains that the control method for the display device can control the operating modes of the display device 000, including at least a safety mode and a usage mode. The safety mode can be understood as a non-use mode or a driver anti-interference mode. In the safety mode, the flexible display module 10 can remain inactive regardless of the orientation of its light-emitting surface 10A; or, even if the light-emitting surface 10A of the flexible display module 10 is performing display operations such as playing music or providing a viewing experience for users other than the driver, the first motor assembly 401 controls the rotation of the universal structure, causing the light-emitting surface of the flexible display module to face away from the user. Figure 44 The driver M, as illustrated in the diagram, can avoid the flexible display module 10 affecting the driver M, thus contributing to driving safety. Optionally, the driver M, located in the driver's seat, can select the display device 000 to enter a safety mode via voice control or button presses. This allows the driver to control the light-emitting surface 10A of the flexible display module 10 away from the driver's field of vision or to turn off the flexible display module 10, thus improving driving safety. The usage mode can be understood as a mode where the user needs to interact with the flexible display module 10. In this mode, the first motor assembly 401 can control the rotation of the universal structure 30, so that the light-emitting surface 10A of the flexible display module 10 faces the user. The light-emitting surface 10A of the flexible display module 10 is as close as possible to the user's, such as the driver M's, field of vision, allowing the user to conveniently operate the light-emitting surface 10A of the flexible display module 10 without having to turn their head to divert their driving attention.

[0143] In some alternative embodiments, please refer to the references. Figure 1 , Figures 8-10 , Figure 46 , Figure 46This is another flowchart of a control method for a display device provided in an embodiment of the present invention. In the control method for a display device provided in this embodiment, the operating modes of the control display device 000 include at least a security mode and a usage mode; wherein, the usage mode further includes a privacy mode.

[0144] In privacy mode, the second motor assembly 402 controls the hinge assembly 1011 to bend, adjusting the curvature of the flexible display module 10 so that the light-emitting surface 10A of the flexible display module 10 faces only the user.

[0145] This embodiment explains the control method for the display device. The operating modes of the display device 000 include at least a safety mode and a usage mode. The usage mode can be understood as the mode in which the user needs to interact with the flexible display module 10. In this mode, the first motor assembly 401 can control the rotation of the universal structure 30 so that the light-emitting surface 10A of the flexible display module 10 faces the user. The light-emitting surface 10A of the flexible display module 10 is as close as possible to the user's, such as the driver M's, field of vision. This allows the user to conveniently operate the light-emitting surface 10A of the flexible display module 10 without having to turn their head to divert their driving attention. Furthermore, this usage mode can also include a privacy mode. In privacy mode, after the sensor 102 senses the user's location, the hinge assembly 1011 receives a bending command and further bends to change its curvature. The second motor assembly 402 can further control the bending of the hinge assembly 1011 to adjust the curvature of the flexible display module 10, so that the light-emitting surface 10A of the flexible display module 10 faces only the user. Through the joint adjustment of the universal structure 30 and the hinge assembly 1011, the optimal screen viewing angle for the user is achieved, which better improves the safety of use and the display effect. It can also improve privacy by making the light-emitting surface 10A of the flexible display module 10 face only the user.

[0146] As can be seen from the above embodiments, the display device and control method provided by the present invention achieve at least the following beneficial effects:

[0147] The display device provided by this invention includes a flexible display module and a support. The flexible display module includes a supporting back plate disposed on one side of the backlight surface of the flexible display module. The supporting back plate provides support for the flexible display panel, allowing the user to view the display image from the light-emitting side of the flexible display module. This invention incorporates sensors electrically connected to a universal joint via a first motor assembly. Feedback information sensed by the sensors, such as user position feedback or sound feedback, is transmitted to the first motor assembly. The first motor assembly calculates and transmits kinetic energy to the universal joint, causing it to change its direction. This, in turn, controls the direction of the supporting back plate, thereby changing the direction of the flexible display module and ensuring that the light-emitting surface of the flexible display module faces the user as much as possible, achieving a better viewing angle for the user. And / or, the present invention sets the sensor to be electrically connected to the hinge assembly via the second motor assembly. The feedback information sensed by the sensor, such as the user's position feedback, sound feedback, etc., is transmitted to the second motor assembly. After the second motor assembly calculates and transmits the kinetic energy to the hinge assembly, it causes the hinge assembly to change its curvature, such as changing from a planar shape to a curved shape, or from a curved shape with a smaller curvature to a curved shape with a larger curvature, thereby controlling the curvature of the support back plate to change the curvature of the flexible display module. By setting the light-emitting surface of the flexible display module to a curved shape, the light-emitting surface of the flexible display module is made to face the user as much as possible, achieving a better viewing angle for the user. The display device of this invention can be applied to the central control screen area of ​​an in-vehicle display system. Even if the display device is far from the driver's position, the light-emitting surface of the flexible display module can be adjusted to face the driver at a better angle by controlling the first motor assembly and the universal joint, and the second motor assembly and the hinge assembly, according to the driver's position. This allows the driver to view the display screen of the flexible display module without turning their head during human-vehicle interaction, enabling screen operation when needed. This also prevents the driver's gaze from leaving the driving direction while the vehicle is in motion, further improving driving safety. Furthermore, after the flexible display module's light-emitting surface is oriented towards the user under the control of the universal joint, the hinge assembly can control the light-emitting surface of the flexible display module to have different degrees of curvature. Within the user's viewing range, this effectively blocks ambient light, improving the contrast when viewing the display device and thus allowing the user to achieve the best possible viewing experience and increasing user satisfaction.
