Description

Technical Field

[0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background Art

[0002] With the development of OLED (Organic Light Emission Diode) display technology in recent years, new flexible display products and research have received more and more attention. Flexible display screens have the characteristics of being bendable and rollable. By using these characteristics, the display device can be rolled or folded, making it convenient for people to carry and use the display device. The sliding roll design that combines folding and rolling is more advantageous in appearance and practicality.

[0003] Sliding and rolling is another innovative application area of ​​flexible display panels. This form allows consumers to switch the display area of ​​the flexible panel at will according to their needs. This is not only convenient for users to carry it with them, but also provides users with a user experience that is superior to that of folding display panels. It is an important direction for the development of flexible display panels.

[0004] When the sliding flexible display is in the unfolded state and undergoes a whole-machine drop test, since the retraction rate of the casing is greater than the retraction rate of the screen, the casing will exert a greater pulling force on the screen, resulting in poor display or touch function of the screen. Summary of the invention

[0027] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0028] Figure 1-4 An embodiment of the display device of the present invention is shown, which includes a shell, a flexible display screen 20 and a locking mechanism. The display device of the embodiment of the present application can be used in terminal devices such as mobile phones, tablet computers or other portable electronic devices. In this embodiment, a mobile phone is taken as an example for description.

[0029] The housing includes a fixed portion 11, a movable portion 12 and a driving component 13. The movable portion 12 is located on one side of the fixed portion 11, and the two can move relative to each other. One end of the driving component 13 is connected to the fixed portion 11, and the other end is connected to the movable portion 12, so that the driving component 13 can drive the movable portion 12 to move relative to the fixed portion 11. Specifically, in this embodiment, the movable portion 12 is slidably connected to the fixed portion 11, that is, the movable portion 12 can slide relative to the fixed portion 11. For example, a slide rail can be provided on the fixed portion 11, and the movable portion 12 can move along the slide rail to make the movable portion 12 move away from or close to the fixed portion 11. It can be understood that the movement is driven by the driving component 13, that is, the driving component 13 can drive the movable portion 12 to move in a direction away from or close to the fixed portion 11 in response to an external control signal.

[0030] The driving component 13 can drive the moving part 12 to move to the first position and the second position. Figure 1 , 2 When the movable part 12 is in the first position, it is far away from the fixed part 11, and the display device can obtain the largest display area, that is, the display device is in an unfolded state to meet the user's demand for large-screen display. In combination with 3 and 4, when the movable part 12 is in the second position, it is close to the fixed part 11, and the display device can obtain the smallest external size, that is, the display device is in a collapsed state, which is easy to carry.

[0031] In this embodiment, the first position and the second position can be regarded as two extreme positions of the movement of the moving part 124 relative to the fixed part 11. In the first position, the display area of ​​the flexible display screen 20 reaches the maximum state, and under normal circumstances, the moving part 12 can no longer move away from the fixed part 11. In the second position, the display area of ​​the flexible display screen 20 reaches the minimum state, and under normal circumstances, the moving part 12 can no longer move towards the fixed part 11.

[0032] It is understood that, in the embodiments of the present application, the expressions of the first position, the second position, the expanded state, and the contracted state all refer to the relative position of the movable portion 12 and the fixed portion 11. To simplify the expression, expressions such as "the movable portion 12 is in the first position", "at the first position", or "expanded state" refer to the movable portion 12 being in the first position relative to the fixed portion 11, and expressions such as "the movable portion 12 is in the second position", "at the second position", or "contracted state" refer to the movable portion 12 being in the second position relative to the fixed portion 11.

[0033] In this embodiment, when the movable part 12 is in the first position, the width of the display device is greater than the width in the second position, so that the width of the flexible display screen 20 can be changed. Specifically, one end of the flexible display screen 20 is connected to the fixed part 11, and the other end is accommodated in the shell. The middle part of the flexible display screen 20 is wound around the movable part, so that part of the flexible display screen 20 is accommodated in the shell. With the movement of the movable part 12, the display screen 20 accommodated in the shell can be partially unfolded on the movable part 12, or the flexible display screen 20 unfolded on the movable part 12 can be retracted into the shell.

[0034] It is understandable that one end of the flexible display screen 20 accommodated in the housing can be connected to the fixed portion 11 via an elastic element, so that when the movable portion 12 moves toward the fixed portion 11 , the elastic element provides contraction power to the flexible display screen 20 .

[0035] In this embodiment, the driving component 13 includes a motor 131, a screw rod 132, a gear 133 and a connecting rod, wherein the motor 131 is fixed to the fixed part 11, the screw rod 132 is connected to the output shaft of the motor 131, the gear 133 is fixed to the end of the screw rod 132, one end of the connecting rod is sleeved on the screw rod 132, and the other end is connected to the moving part 12. The driving component 13 adopts a threaded transmission structure, and the motor 131 drives the screw rod 132 to rotate, thereby driving the connecting rod to move back and forth, thereby driving the moving part 12 to move, and at the same time, the screw rod 132 drives the gear 133 to rotate, and then the gear 133 drives the movable part to move.

[0036] Specifically, the connecting rod is generally in an L-shaped structure, which includes a crossbar 134 and a vertical rod 135 connected to each other, wherein one end of the vertical rod 135 is sleeved on the screw rod 132, and the vertical rod 135 is arranged perpendicular to the screw rod 132, and one end of the crossbar 134 is connected to the moving part 12, and the crossbar 134 is arranged parallel to the screw rod 132. The screw rod 132 is arranged along the movement direction of the moving part 12, and the rotation of the screw rod 132 drives the vertical rod 135 and the crossbar 134 to move, thereby driving the moving part 12 to move.

[0037] The locking mechanism includes a positioning structure 31 and a movable part 32. The positioning structure 31 is arranged on the driving part 13. The movable part 32 is driven by the driving part 13 to move toward the positioning structure 31 and finally engages with the positioning structure 31. At this time, the movable part 12 is located at the first position. That is to say, through the engagement of the movable part 32 with the positioning structure 31, the positions of the movable part 12 located at the first position and the fixed part 11 are relatively fixed. When the display device is impacted, such as accidentally falling, the locking mechanism can play an effective fixing role, so that the impact force is absorbed by the fixed part 11 and the movable part 12 together, preventing the movable part 12 from being easily moved to the second position due to the impact force, thereby preventing the shell from applying a large pulling force to the flexible display screen 20, resulting in poor display or touch function of the screen, thereby improving the impact resistance of the display device.

[0038] In this embodiment, the positioning structure 31 includes a first boss 311 and a second boss 312 arranged on the cross bar 134. The first boss 311 and the second boss 312 are arranged at an interval, and a accommodating space is formed therebetween. When driven by the driving component 13, the end of the movable component 32 can be moved into the accommodating space, and the two side surfaces of the movable component 32 are respectively abutted against the first boss 311 and the second boss 312, thereby realizing the engagement between the movable component 32 and the positioning structure 31.

[0039] The movable part 32 can be configured as a rack structure slidably connected to the fixed part 11, and the gear 133 is engaged with the rack structure, and the gear 133 can drive the rack structure to move. Specifically, the moving direction of the movable part 32 is perpendicular to the direction of the crossbar 134. Figure 4 In the direction shown, the cross bar 134 moves to the left and the movable component 32 moves downward. When the movable part 12 moves to the first position, the end of the movable component 32 moves between the first boss 311 and the second boss 312, and the movable component 32 engages with the positioning structure 31, so that the movable component 32 fixes the first position of the movable part 12 and the fixed part 11 relatively.

[0040] In this embodiment, a first slide groove 14 is provided on the fixing portion 11, and the rack structure is located in the first slide groove 14. The first slide groove 14 extends in a direction perpendicular to the cross bar 134, so that the rack structure can move along the first slide groove 14, and finally its end moves to between the first boss 311 and the second boss 312, thereby realizing the engagement between the rack structure and the first boss 311 and the second boss 312, that is, the first boss 311, the second boss 312 and the first slide groove 14 can jointly block the movement of the cross bar 134.

[0041] In some embodiments, the movable component 32 can be configured as a swing gear hinged to the fixed portion 11. Through the engagement of the gear 133 with the swing gear, the gear 133 can drive the swing gear to rotate, so that the end of the swing gear can be rotated between the first boss 311 and the second boss 312, thereby realizing the engagement of the movable component 32 with the positioning structure 31, and then the movable component 32 makes the first position of the movable portion 12 and the fixed portion 11 relatively fixed.

[0042] The fixing portion 11 in this embodiment is also provided with a second slide groove 15, in which the cross bar 134 is located. The second slide groove 15 extends in a direction parallel to the screw rod 132, and the cross bar 134 can move along the second slide groove 15 and eventually move to a position engaged with the movable component 32, i.e., the second position. The first slide groove 14 and the second slide groove 15 can ensure smooth movement of the movable component 32 and the connecting rod 13.

[0043] like Figure 5 As shown, the positioning structure 31 also includes a retractable portion, which can shrink and release the movable part 32 so that the movable part 12 moves in a direction close to the fixed part 11. That is to say, when the movable part 12 is about to move from the first position to the second position, the retractable portion shrinks, thereby releasing the movable part 32. Specifically, the first boss 311 is set as a retractable structure to form a retractable portion, that is, the first boss 311 can be retracted into the cross bar 134, so that the cross bar 134 moves to the right, and at the same time, the gear 133 drives the movable part 32 to move upward, so that the movable part 12 moves to the second position. Exemplarily, an electromagnet can be set in the cross bar 134, and when the electromagnet is energized, it attracts the first boss 311 and shrinks the first boss 311 into the cross bar 134. After the electromagnet is powered off, the first boss 311 can be lifted up by a spring to achieve reset. It can be understood that the first boss 311 in the positioning structure 31 is set as a retractable structure, and the second boss 312 is set as a fixed protrusion structure, so that the cross bar 134 can only move toward the right side but not toward the left side, that is, the movable part 12 can only move toward the second position but cannot move in the direction away from the fixed part 11, so as to avoid operational errors.

[0044] In this embodiment, the moving part 12 is provided with a reel 121, and one end of the cross bar 134 is connected to the reel 121, so that the cross bar 134 can drive the moving part 12 to move through the reel 121. The middle part of the flexible display screen 20 is wound on the reel 121. When the moving part 12 moves and the flexible display screen 20 is unfolded or retracted to the moving part 12, the reel 121 contacts the flexible display screen 20, playing a role in guiding the flexible display screen 20.

[0045] The invention also discloses an electronic device, which has the above-mentioned display device and thus has the functional effect of the display device.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
