Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Referring to fig. 1 to fig. 3, fig. 1 is a top view of an electronic device according to an embodiment of the present disclosure. Fig. 2 is a schematic sectional view taken along a-a in fig. 1. FIG. 3 is a schematic cross-sectional view taken along the line A-A of FIG. 1 according to another embodiment of the present application. The present embodiment provides an electronic device 1 including a reel 10, a flexible screen 20, and a peripheral circuit 30. The reel 10 has a receiving space 11 therein, and the reel 10 is rotatable. The flexible screen 20 is installed on the reel 10, the flexible screen 20 includes a connecting end 21 and a free end 22 which are opposite to each other, the connecting end 21 is installed in the accommodating space 11, and the free end 22 is installed outside the accommodating space 11. The peripheral circuit 30 is disposed in the accommodating space 11, and the peripheral circuit 30 is connected to the connecting end 21.

The electronic device 1 provided in the present embodiment includes, but is not limited to, a mobile terminal such as a mobile phone, a tablet Computer, a notebook Computer, a palmtop Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, and a pedometer, and a fixed terminal such as a Digital TV and a desktop Computer. In addition, the functionally distributed electronic apparatus 1 may include the bending screen electronic apparatus 1, the scroll 10 screen electronic apparatus 1, and the like. In the present embodiment, the electronic device 1 is illustrated as a reel 10 and the electronic device 1 is displayed.

The electronic apparatus 1 provided in the present embodiment includes a reel 10, a flexible screen 20, and a peripheral circuit 30. Wherein the reel 10 is the component controlling the movement of the flexible screen 20. The flexible screen 20 may be mounted on the scroll 10, and the scroll 10 may be rotated (in a scrolling direction as shown at D1 in fig. 2 and 3) to "roll in" or "roll out" the flexible screen 20 using the scroll 10. In the display state, the electronic device 1 may have a portion of the flexible screen 20 laid out on the outside for display. While the remaining flexible screen 20 is attached to the reel 10 or is wound on the reel 10. The term "rolled in" means that the flexible screen 20 at least partially disposed on the outer side is rolled onto the reel 10 by the rotation of the reel 10, so as to reduce the display area of the flexible screen 20 on the outer side, thereby reducing the overall size of the electronic device 1 and using the electronic device 1 as a mobile phone. The term "roll out" means that the flexible screen 20 wound around the reel 10 is at least partially rolled to the outside by the rotation of the reel 10, and the display area of the flexible screen 20 on the outside is increased (for example, the area of 6 inches may be changed to the area of 8 inches or more), so that the overall size of the electronic device 1 is increased, and the electronic device 1 is used as a flat panel. The switching between the mobile phone and the tablet form is realized, and then a novel multifunctional electronic device 1 is realized.

For the rotation of the reel 10, the reel 10 may be rotated by the rotation of a motor, or the rotation of the reel 10 may be manually controlled by a user. The present application is not limited thereto.

The flexible screen 20 generally includes a free end 22 and a connecting end 21 opposite each other, wherein the connecting end 21 is generally mounted on the roller 10, such that the flexible screen 20 rotates under the rotation of the roller 10. The free end 22 does not need to be connected to the reel 10, and the free end 22 can be disposed outside for the user to view and hold. The electronic device 1 includes a peripheral circuit 30 in addition to the flexible screen 20 and the hinge. The peripheral circuit 30 generally functions to control the display of the flexible screen 20, and therefore the peripheral circuit 30 may also be referred to as a control circuit or a driving circuit. The peripheral circuits 30 include, but are not limited to, DD ICs, and TOUCH ICs. The peripheral circuitry 30 is typically electrically connected to the flexible screen 20 at one end and to the circuit board at the other end. In the related art, the peripheral circuit 30 is generally connected to the free end 22. This can cause a number of problems. For example, first, since the peripheral circuit 30 does not have a function of displaying a screen, connecting the peripheral circuit 30 to the free end 22 reduces an effective display area and a screen occupation ratio on the premise of the same exposed area of the flexible screen 20.

Secondly, since the peripheral circuit 30 needs to be connected to the circuit board through the traces and the peripheral circuit 30 is connected to the free end 22, the peripheral circuit 30 moves along with the movement of the flexible screen 20, so that the position of the peripheral circuit 30 relative to the circuit board changes. This would require longer traces to extend the flexible screen 20 to the longest position, i.e., the position where the free end 22 is furthest from the circuit board, while still ensuring that the traces remain electrically connected to the peripheral circuitry 30 and the circuit board. Therefore, a more complicated routing circuit needs to be designed in the electronic device 1, which increases the design difficulty of the electronic device 1.

In view of this, in order to solve the above problem, the present embodiment solves the above problem by changing the position of the peripheral circuit 30. In the present embodiment, the connection terminal 21 is provided in the housing space 11, the peripheral circuit 30 is also provided in the housing space 11, and the peripheral circuit 30 is connected to the connection terminal 21. Therefore, the peripheral circuit 30 which is originally arranged on the periphery can be transferred into the scroll 10, the peripheral space is saved, the screen occupation ratio of the flexible screen 20 is improved on the premise that the same area of the flexible screen 20 is exposed, the area of the display area of the exposed flexible screen 20 is increased, and the exquisite design is realized.

In addition, since the peripheral circuit 30 is disposed in the reel 10 in the present embodiment, when the reel 10 rotates to drive the flexible screen 20 to move, the position of the peripheral circuit 30 relative to the circuit board is substantially not changed, thereby reducing the length and design difficulty of the wire between the peripheral circuit 30 and the circuit board, preventing the poor wire, improving the reliability, and making the electronic device 1 lighter.

Alternatively, the roll 10 may be machined to an archimedes spiral to improve the roll effect of the flexible screen 20 when it is rolled onto the roll 10, preventing excessive local bending.

Alternatively, the connection terminal 21 and the peripheral circuit 30 may be adhered to the inside of the reel 10, so as to improve the connection performance of the flexible screen 20 and prevent the adhesion reliability of the flexible screen 20 directly to the outside of the reel 10 from being insufficient.

Referring to fig. 4-5, fig. 4 is a schematic cross-sectional view taken along a direction a-a of fig. 1 according to another embodiment of the present disclosure. Fig. 5 is a schematic cross-sectional view taken along the direction B-B in fig. 1. In this embodiment, the electronic device 1 further includes an electrical connection portion 40, at least a portion of the electrical connection portion 40 is disposed in the accommodating space 11, the electrical connection portion 40 is connected to the peripheral circuit 30, and at least a portion of the electrical connection portion 40 is disposed on the axis O of the reel 10.

As can be seen from the above, it is also necessary to design the traces to electrically connect the peripheral circuit 30 with the circuit board. Therefore, the present embodiment can add the electrical connection portion 40 to electrically connect the peripheral circuit 30 and the circuit board by using the electrical connection portion 40. Alternatively, the electrical connection portion 40 includes, but is not limited to, a Flexible Printed Circuit (FPC). Since the peripheral circuit 30 is disposed in the accommodating space 11, in the present embodiment, at least a portion of the electrical connection portion 40 can be disposed in the accommodating space 11, that is, the electrical connection portion 40 disposed outside the spool 10 is disposed inside the spool 10, so that the space of the electrical connection portion 40 is saved. And because the position between the electrical connection part 40 and the main board in the reel 10 of the flexible screen 20 is basically kept unchanged when the flexible screen moves, the length of the electrical connection part 40 can be reduced, and the design difficulty of the electrical connection part 40 is simplified.

In addition, in the present embodiment, at least a part of the electrical connection portion 40 may be provided on the axial center O of the spool 10. When the reel 10 rotates, the reel 10 rotates around the axis O of the reel 10, so that at least part of the electrical connection portion 40 is disposed on the axis O, and the electrical connection portion 40 disposed on the axis O can be kept stationary when the reel 10 rotates, thereby ensuring the connection stability between the electrical connection portion 40 and the circuit board and preventing the electrical connection portion 40 and the circuit board from breaking.

Referring to fig. 6 to 8, fig. 6 is a schematic view of the flexible panel 20, the peripheral circuit 30, and the electrical connection portion 40 according to an embodiment of the present disclosure. FIG. 7 is a schematic cross-sectional view taken along the line A-A of FIG. 1 according to yet another embodiment of the present application. FIG. 8 is a schematic cross-sectional view taken along the line B-B of FIG. 1 in another embodiment of the present application. In this embodiment, the electronic device 1 further includes a fixing shaft 50, the fixing shaft 50 is disposed in the accommodating space 11, an axial center O of the fixing shaft 50 is collinear with an axial center O of the reel 10, and the reel 10 is rotatable relative to the fixing shaft 50; the electrical connection portion 40 includes a first portion disposed in the fixed shaft 50 and a second portion connecting the first portion and the peripheral circuit 30.

In this embodiment, a fixing shaft 50 may be additionally provided, and the fixing shaft 50 may be also disposed in the accommodating space 11 of the reel 10, wherein the axis O of the fixing shaft 50 is collinear with the axis O of the reel 10, and the reel 10 may rotate relative to the fixing shaft 50, so that the reel 10 may not collide with the fixing shaft 50 when rotating. It will also be appreciated that the fixed shaft 50 is stationary in itself and that the reel 10 can rotate relative to the fixed shaft 50. The electrical connection portion 40 includes a first portion and a second portion. The first portion and the second portion are connected in a bending manner, but the included angle between the first portion and the second portion is not limited in the application, for example, the first portion is perpendicular to the second portion. In addition, in the present embodiment, the first portion is disposed inside the fixed shaft 50 and connected to the fixed shaft 50, and the second portion is used to connect the first portion and the peripheral circuit 30.

With the embedded design of the present embodiment, the first portion can be kept stationary in the fixed shaft 50 because the fixed shaft 50 is kept stationary during the rotation of the reel 10, and only the second portion connected to the peripheral circuit 30 can rotate around the first portion and be wound on the first portion or the fixed shaft 50. The first portion can be connected with the mainboard interface through a board-to-board connector, so that the control function of the circuit is realized.

Alternatively, the first portion may be disposed on the axial center O of the fixed shaft 50, and the first portion may be disposed on the axial center O of the spool 10.

Alternatively, the outer circumference of the spool 10 is 1-10 times the outer circumference of the fixed shaft 50, so that during the rotation of the spool 10, a sufficient space is secured in the spool 10 to accommodate the rolling and unrolling of the second portion.

Please refer to fig. 2, fig. 3, and fig. 9, wherein fig. 9 is a schematic perspective view of a flexible screen 20 according to an embodiment of the present application. In this embodiment, the connection end 21 includes a flat portion 211 and a bent portion 212 connected to each other, the flat portion 211 is farther from the free end 22 than the bent portion 212, and the peripheral circuit 30 is connected to the flat portion 211.

In this embodiment, the connecting end 21 may include a flat portion 211 and a bent portion 212, and the flat portion 211 is far away from the free end 22 than the bent portion 212. It is also understood that the connection terminal 21 may be bent again after being disposed in the receiving space 11, so that the connection terminal 21 is better disposed in the receiving space 11 and the peripheral circuit 30 is connected.

Optionally, the present embodiment may make the flexible screen 20 cut into the outer shaft at the minimum bending angle, so as to keep the tangent line of the bending area of the outer shaft and the screen coincident, and the normal direction is kept consistent. Optionally, the bend of the bent portion 212 is between 1mm and 3 mm. Specifically, when the display function is not considered and only the circuit wiring function is maintained to be normal, the bending angle may reach 1 mm.

In this embodiment, the step groove 12 may be provided in the reel 10, and the flexible panel 20 may be attached using the step groove 12, thereby reducing the protrusion of the flexible panel 20 when it is curled. In addition, an opening 13 communicating with the accommodating space 11 may be opened in a side wall of the stepped groove 12, and the connection end 21 of the flexible panel 20 may be provided in the accommodating space 11 through the opening 13.

Alternatively, the steps of the present embodiment are positioned and oriented in the same direction as the normal line of the cut of the flexible screen 20, and it can also be understood that the peripheral side surface 14 of the reel 10 at the cut is parallel to the flexible screen 20 at the cut, thereby ensuring the bending reliability of the flexible screen 20.

In this embodiment, the electronic device 1 further includes a driving mechanism 80, the driving mechanism 80 is disposed in the housing 60, the driving mechanism 80 is connected to the housing 60, and when the sliding end 61 slides in a direction away from the reel 10, the driving mechanism 80 is configured to apply a pulling force (in a direction shown by F in fig. 18) to the sliding end 61 in a direction away from the reel 10.

As can be seen from the above, when the sliding end 61 slides in a direction away from the reel 10, i.e. the housing 60 is unfolded, the flexible screen 20 is driven to move and unfold. It is also understood that the flexible screen 20 originally rolled on the roll 10 is rolled out, so that the flexible screen 20 has a tendency to bend and warp, thereby resulting in an uneven surface of the flexible screen 20. Therefore, the drive mechanism 80 can be added to the present embodiment, and the drive mechanism 80 is provided in the housing 60 and connected to the housing 60. And the driving mechanism 80 is configured to apply a pulling force to the sliding end 61 in a direction away from the reel 10 when the sliding end 61 slides in the direction away from the reel 10. The driving mechanism 80 is used for applying a pulling force to the sliding end 61 of the reel 10, and since the free end 22 is connected with the sliding end 61, it can also be understood that the driving mechanism 80 is used for applying a pulling force to the free end 22 of the flexible screen 20 to push the flexible screen 20 to be unfolded outwards, so as to maintain the unfolded state of the flexible screen 20 and keep the screen to be tightened, thereby reducing the bending stress of the flexible screen 20 by using the pulling force, tightening the flexible screen 20 more, and improving the flatness of the unfolded flexible screen 20.

Alternatively, the drive mechanism 80 includes, but is not limited to, a hydraulic drive mechanism 80, such as in a hydraulic lever design. And the circulation of the hydraulic pressure may use an electric motor as a power source of the hydraulic pump. The integrated formation of the conduit and reservoir within the housing 60 keeps the flexible screen 20 taut by increasing or decreasing the pressure to push the hydraulic sleeve out of the way, by winding the hole on the spool 10, and by hydraulic retraction. The hydraulic pressure can adjust the force according to the feedback, and the support of the flexible screen 20 in the using process is guaranteed.
