In some related art, a display terminal or a mobile terminal having a flexible screen is folded in an everting manner, i.e., a display surface of the display screen is folded outward, but the thickness dimension of the display terminal or the mobile terminal in the folded position cannot be reduced in this manner. In other technologies, the display screen is folded in an inward-turned manner, that is, the display surface of the display screen is folded in an inward-turned manner, and the folding manner, due to the fixed folding position and the reduced bending radius for reducing the size, can cause the display screen at the bending position to easily generate faults such as black screen.
In order to solve the above-mentioned problems, the embodiments of the present disclosure provide a display terminal 100, which can be used for communication connection with other intelligent devices to display images, and can also be applied to mobile terminals such as mobile phones.
Fig. 1 is a schematic view showing an unfolded state of a display terminal 100 according to an embodiment of the present disclosure, fig. 2 is a schematic view showing a completely housed state of the display terminal 100 according to an embodiment of the present disclosure, and fig. 3 and 4 are schematic views showing an internal structure of a first housing chamber 120 of the display terminal 100 according to an embodiment of the present disclosure.
As shown in fig. 1 to 4, the display terminal 100 may include: a flexible screen 110, a first receiving chamber 120, a second receiving chamber 130.
The flexible screen 110 may be an OLED screen (organic light emitting diode screen), which can be bent or rolled up to some extent, and has a display surface for displaying an image. The circuit arrangement of the flexible screen 110 may be reasonably arranged according to the actual structure, for example, the circuit arrangement may be arranged in the first accommodating cavity 120 or the second accommodating cavity 130, or may be distributed in the first accommodating cavity 120 and the second accommodating cavity 130 at the same time.
The first accommodating cavity 120 includes a first cavity 121 and a first opening 122, a vertical shaft 123 is disposed in the first cavity 121, a first end 111 of the flexible screen 110 is connected to the vertical shaft 123, the flexible screen 110 may extend from the first opening 122, and the flexible screen 110 may be wound around the vertical shaft 123.
The first cavity 121 of the first accommodating cavity 120 is mainly used for accommodating the flexible screen 110, and may take an approximately cylindrical shape, so that the volume is relatively most compact, and the first cavity 121 may be provided in a polygonal cylinder shape or the like for circuit arrangement or appearance.
A vertical shaft 123 may be fixedly disposed in the first cavity 121, and an extending direction of the vertical shaft 123 may be identical to a cylindrical extending direction of the first cavity 121, and an extending length of the vertical shaft 123 may be longer than a width of the first end 111 of the flexible screen 110, so as to ensure that the flexible screen 110 may be wound on the vertical shaft 123 better and more stably. The fixed position of the vertical shaft 123 may be located at the center of the first cavity 121, or may be disposed at a non-center position according to other structures that need to be accommodated in the first cavity 121.
The first opening 122 may be disposed at one side of the first cavity 121, and the extension length of the first opening 122 may be the same as or slightly smaller than the extension length of the first cavity 121 under the condition that the flexible screen 110 is guaranteed to be smoothly drawn out or retracted. The first opening 122 may be formed so as to open to the cylindrical structure side surface of the first chamber 121, or may be provided so as to open to the cylindrical structure side surface of the first chamber 121 and extend outside the first chamber 121 by a predetermined size, as shown in fig. 1 to 3.
In one embodiment, as shown in FIG. 3, a coil spring 124 is disposed within the first receiving chamber 120, with the unwind end 1241 of the coil spring 124 being connected to the first end 111 of the flexible screen 110 and the wind-up end 1242 of the coil spring 124 being fixedly connected to the vertical axle 123. In this embodiment, the two ends of the coil spring 124 are respectively connected with the flexible screen 110 and the vertical shaft 123, so that the flexible screen 110 can be conveniently driven to be wound on the vertical shaft 123 by the winding force of the coil spring 124. In other embodiments, the flexible screen 110 may be driven to be wound and stored by other power mechanisms, such as a winding motor.
The second accommodating cavity 130 may include a second cavity 131 and a second opening 132, where the second opening 132 is disposed opposite to the first opening 122, and the second end 112 of the flexible screen 110 is connected in the second cavity 131.
The second receiving chamber 130 may have a cylindrical structure similar to the first receiving chamber 120. The second cavities 131 may be the same shape as the first cavities 121, e.g., all have a cylinder-like structure; the second cavity 131 may also be different from the first cavity 121, for example, in some embodiments, in a case where the second cavity 131 is not used to house the flexible screen 110, a cylindrical structure with a smaller volume may be used, the first cavity 121 uses a cylinder, and the second cavity 131 uses a polygonal cylindrical structure with a smaller size, so as to reduce the overall volume of the display terminal 100.
The second accommodating chamber 130 may be arranged similarly to the first accommodating chamber 120, and may be provided with a vertical shaft or the like, and the flexible screen 110 may be accommodated in the first accommodating chamber 120 and the second accommodating chamber 130 in a wound form in the accommodated state. In other embodiments, the second accommodating chamber 130 may be provided differently from the first accommodating chamber 120, and the flexible screen 110 is accommodated in the first accommodating chamber 120 only in a wound form in the accommodated state, and the second accommodating chamber 130 fixes the second end 112 of the flexible screen 110, and only a portion of the flexible screen 110 near the second end 112 is accommodated in the second accommodating chamber 130, so that the second accommodating chamber 130 can be reduced in volume or used for accommodating other components.
Through the above arrangement, when the first accommodating chamber 120 is far away from the second accommodating chamber 130, the flexible screen 110 is pulled out from at least the first accommodating chamber 120, and is unfolded in the space region between the first accommodating chamber 120 and the second accommodating chamber 130, and when the first accommodating chamber 120 and the second accommodating chamber 130 reach the farthest distance, that is, the flexible screen 110 is in a fully unfolded state, and is stretched to the greatest extent, so that the display surface is ensured to be exposed to the greatest extent. When the first accommodating chamber 120 and the second accommodating chamber 130 are close to each other, the flexible screen 110 is at least partially wound around the vertical shaft 123, and when the first accommodating chamber 120 and the second accommodating chamber 130 reach the closest position, that is, the flexible screen 110 is in a fully accommodated state, the overall volume of the display terminal 100 is reduced by winding and accommodation.
Through any of the above embodiments, the flexible screen 110 can be conveniently stored in a winding form, so that in the storage state, the size of the display terminal 110 is reduced, the flexible screen 110 is protected, and the flexible screen 110 can be conveniently unfolded for displaying images to a user.
In one embodiment, the flexible screen 110 is wrapped with the display surface facing away from the axis of the wrap. In this embodiment, the display surface is wound and stored in an outward manner, so that the display surface is prevented from being extruded, particularly at a position close to the winding center, that is, close to one end of the flexible screen 110, for example, a position close to the first end 111, the winding radius is relatively small, and faults such as a black screen can be avoided by winding in an outward manner.
Meanwhile, the diameter of the vertical shaft 123 in the embodiment of the present disclosure may be adjusted as required, so as to balance the influence of the volume and the winding radius after winding on the flexible screen 110. While in other embodiments, coil springs 124 of different lengths may be employed to adjust the winding radius of the flexible screen 110.
In one embodiment, as shown in fig. 2, when the flexible screen 110 is in the fully stored state, the first opening 122 is in contact with the second opening 132; the first opening 122 is provided with a first engagement member (not shown) and the second opening 132 is provided with a second engagement member (not shown) that mates with the first engagement member, the first engagement member engaging the second engagement member when the flexible screen 110 is in the fully stowed condition. In this embodiment, when the flexible screen 110 is in the fully-stored state, the first opening 122 contacts with the second opening 132, so that the first accommodating cavity 120 and the second accommodating cavity 130 form a relatively airtight cavity, so that the flexible screen 110 is fully stored inside, and exposure is avoided, so as to protect the flexible screen 110. Meanwhile, in this state, in order to enable the first receiving chamber 120 and the second receiving chamber 130 to be relatively firmly connected, a first engagement member may be disposed at the first opening 122, and a second engagement member matched with the first engagement member may be disposed at the second opening 132, wherein the first engagement member and the second engagement member may be a locking pin, a locking hole, an electromagnet, or other forms of engagement members, respectively, may be engaged with the second engagement member through the first engagement member, so that the first receiving chamber 120 and the second receiving chamber 130 may be maintained in a combined state within a certain external force range, and may be conveniently disengaged, thereby conveniently pulling the first receiving chamber 120 and the second receiving chamber 130 apart, and thus, the flexible screen 110 may be unfolded.
In one embodiment, as shown in fig. 3 and 4, the display surface and/or the back surface of the first side of the flexible screen 110 is provided with a first strip 1101 protruding from the surface of the flexible screen 110. Since there is no guarantee that there will be no rubbing between the wound multi-layered flexible screen 110 or between the flexible screen 110 and the coil springs 124 in some embodiments in the stored state and during movement such as winding or unwinding, in this embodiment, a first strip 1101 protruding from the surface is provided on the display surface of the first side of the flexible screen 110 or on the back surface opposite to the display surface or on both the display surface and the back surface, wherein the first side may be one side between the first end 111 and the second end 112 of the flexible screen 110 (the side above or below the flexible screen 110 as shown in fig. 1), and the first strip 1101 is provided near the side. The first strap 1101 is also flexible to be able to be wound and unwound together with the flexible screen 110, while the flexible strap 1101 may also have a certain elasticity to protect the flexible screen 110. In some embodiments, the flexible strip 1101 disposed on the back surface may be disposed on the back surface of the flexible screen 110 in a larger area, and even spread over the entire back surface of the flexible screen 110, which increases the volume and weight of the display terminal 110, but can maximize the protection of the flexible screen 110 from damage caused by friction between the back surface and the display surface between adjacent layers during the winding process.
In one embodiment, as shown in fig. 3 and 4, the first strip 1101 is a toothed belt; one or two first gears 125 disposed corresponding to the first strips 1101 are disposed in the first receiving chamber 120. In this embodiment, the first strap 1101 is configured as a flexible toothed belt with teeth, and at the same time, at the first opening 122 of the first accommodating cavity 120, a first gear 125 is disposed at a position corresponding to the toothed belt and is engaged with the toothed belt, in this way, stability of the flexible screen 110 after being unfolded is improved, and the position can be relatively fixed, so as to avoid shaking substantially. The first gears 125 may be disposed on the display surface side, the rear surface side, or both sides of the display surface and the rear surface of the flexible screen 110, respectively, according to the arrangement of the toothed belt. In the case where the first gears 125 are provided on both sides of the display surface and the rear surface, the degree of freedom of the flexible screen 110 in one direction after being unfolded can be limited, so that the flexible screen 110 is more stable. In the case of providing one first gear 125, a flexible wheel (not shown), an elastic friction belt (not shown), or the like, which can be engaged with the first gear 125, may be provided at the side opposite to the first gear 125 at the first opening 122, so as to limit the degree of freedom of the flexible screen 110.
In one embodiment, as shown in FIG. 4, the display surface and/or the back surface of the second side of the flexible screen 110 is provided with a second strip 1102 protruding from the surface of the flexible screen 110. Similar to the foregoing embodiments, the second strip 1102 is disposed on a second side opposite to the first side, and the second strip 1102 may be disposed on the display surface side, the back surface side, or both the display surface and the back surface side of the second side, and the second strip 1102 may be the same as or different from the first strip 1101. By providing the first and second strips 1101, 1102 on the first and second sides of the flexible screen 110, respectively, it is ensured that the flexible screen 110 is not damaged during storage or movement.
In one embodiment, the second strip 1102 is a toothed strip; one or two second gears (not shown) disposed corresponding to the second strips 1102 are disposed in the first receiving chamber 120. The second gear may be disposed in the same manner as the first gear 125, which is not described herein.

In this embodiment, the flexible screen 110 is only wound and stored in the first accommodating cavity 120, and the second end 112 of the flexible screen 110 is fixed in the second accommodating cavity 130, so that the flexible screen 110 can be unfolded to expose the display surface by pulling the second accommodating cavity 130 and the first accommodating cavity 120 relatively. In addition, in the display terminal 100, a circuit corresponding to the flexible screen 110 and components for communication, power supply, auxiliary support and the like are required to be provided, and these components also need to occupy space, and meanwhile, these components need to avoid interference with the flexible screen 110 which is wound and stored, so that the flexible screen 110 is wound and stored only in the first accommodating cavity 120, and the second accommodating cavity 130 can be used for providing other components or reducing the volume.

In this embodiment, a cross link mechanism 140 is connected between the first accommodating cavity 120 and the second accommodating cavity 130, and the cross link mechanism 140 forms a plurality of diamonds through a plurality of hinged links 141, so that the cross link mechanism 140 can stretch or compress, and the first accommodating cavity 120 and the second accommodating cavity 130 can be relatively stable under the unfolding state through the cross link mechanism 140, so that the external force between the first accommodating cavity 120 and the second accommodating cavity 130, including the force in the directions of stretching, torsion and the like, is avoided, adverse effects on the flexible screen 110 are caused, and the stress of the flexible screen 110 is reduced through the auxiliary support of the cross link mechanism 140.
