Description

Technical Field

[0001] The present invention relates to the technical field of OLED display devices, in particular to a flat-curved variable OLED screen, and in particular to a laptop computer with a flat-curved variable OLED screen. Background Art

[0002] OLED, Organic Light-Emitting Diode, also known as organic electric laser display, is a phenomenon of luminescence caused by the injection and recombination of carriers, and its luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules and finally producing visible light. OLED display devices have the advantages of being thinner, lighter and more flexible, and large-size curved screens are one of their important applications.

[0003] On the one hand, the human eyeball has a curvature, and the curvature of the curved screen can ensure that the distance from the eye to the screen is equal, so the curved screen can bring a better sensory experience. On the other hand, a large-size curved screen can bring better display effects, better surround picture effects, and more prominent layering. In short, compared with flat screens, the sensory experience and display effects of curved screens have been greatly improved.

[0004] In the prior art, large-size curved screens generally use a curved back shell as a fulcrum to achieve the bending of the panel, or use a thick back shell to wrap the mechanical structure of the control panel to transform from flat to curved. Due to this limitation, large-size curved screens can usually only be used on TVs or desktop monitors, while notebooks cannot be equipped with curved screens, and the screen cannot be converted between curved and flat surfaces. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a flat curved variable OLED screen and a laptop computer in response to the above-mentioned defects of the prior art, which can take into account the size, space and safety of the display device and adapt to market demand.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0007] A flat curved variable OLED screen, comprising:

[0008] A load-bearing steel plate, wherein the load-bearing steel plate can be bent and deformed after being compressed;

[0009] An OLED display component, wherein the OLED display component is attached to the front panel of the bearing steel plate, and the OLED display component deforms as the bearing steel plate deforms;

[0010] A silicone component, the silicone component is arranged on the rear panel of the bearing steel plate, and a plurality of sealed cavities are arranged in the silicone component;

[0011] An air-charging and air-inflating assembly, the air-charging and air-inflating assembly being in communication with the sealed cavity and being used to control the internal air pressure of the sealed cavity;

[0012] An opening and closing rotating shaft, the bearing steel plate is arranged on the opening and closing rotating shaft.

[0013] Compared with the prior art, the beneficial effect of the present technical solution is that through the coordination of the above-mentioned bearing steel plate, OLED display component, silicone component, inflation and deflation component and opening and closing hinge and other structures, not only can a curved screen be equipped on a smaller laptop computer, but the screen can also be converted between a curved surface and a flat surface, thus completing the application of curved screens on high-end laptop computers.

[0014] Furthermore, a plurality of bending support components are also arranged on the bearing steel plate, each of the bending support components comprises a steel cap and a side steel bar, and the side steel bar is arranged on the steel cap;

[0015] The steel cap is a columnar structure, one end of the steel cap is provided with two waist-shaped concave holes, and the other end of the steel cap is provided with two cylindrical protrusions; in two adjacent steel caps, the two cylindrical protrusions of one of the steel caps are respectively inserted into the two waist-shaped concave holes of the other steel cap;

[0016] When the internal air pressure of the closed cavity increases, the silicone component provides deformation driving force for the steel cap by deformation, and the two cylindrical protrusions of the steel cap deviate from the center of the two waist-shaped concave holes of the other adjacent steel cap, thereby driving the bearing steel plate and the OLED display component to bend, and the OLED display component is converted into a curved state;

[0017] When the internal air pressure of the closed cavity decreases, the silicone component returns to its original state, the silicone component stops providing deformation driving force for the steel cap, the bearing steel plate drives the steel cap, and the two cylindrical protrusions of the steel cap return to the center of the two adjacent waist-shaped recessed holes of the steel cap, and the OLED display component is converted into a planar state.

[0018] The beneficial effect of adopting the above scheme is: by providing a plurality of steel caps connected in sequence, and each steel cap is provided with a side steel bar, combined with the deformation force of the silicone component, the screen can be controlled to convert between a flat state and a curved state.

[0019] Furthermore, the side steel bars are fixed on the rear panel of the bearing steel plate by welding.

[0020] The beneficial effect of adopting the above solution is that the side steel bars are welded and fixed to the rear panel of the bearing steel plate, so that the connection between the side steel bars and the bearing steel plate is more firm, thereby making the state conversion of the screen more reliable.

[0021] Further, the waist-shaped recessed hole comprises a first semicircular portion, a second semicircular portion and a rectangular transition portion;

[0022] The diameters of the first semicircular portion and the second semicircular portion are equal, and the diameters of the first semicircular portion and the second semicircular portion are equal to the width of the rectangular transition portion, and the width of the rectangular transition portion is smaller than the length of the rectangular transition portion.

[0023] The beneficial effect of adopting the above scheme is: a waist-shaped recessed hole is formed by the first semicircular portion, the second semicircular portion and the rectangular transition portion, and a certain rotation space can be reserved in combination with the shape and size of the cylindrical protrusion, so that after the deformation and expansion of the silicone component is controlled by the inflation and deflation component, the screen can eventually be changed into a curved state.

[0024] Furthermore, the opening and closing rotating shaft is a long strip structure, and the opening and closing rotating shaft can perform reciprocating rotational motion around its central axis;

[0025] One end of the opening and closing shaft is provided with two waist-shaped recessed holes, and the other end of the opening and closing shaft is provided with two cylindrical protrusions; the cylindrical protrusion of the steel cap adjacent to one end of the opening and closing shaft is sleeved in the waist-shaped recessed hole at one end of the opening and closing shaft, and the cylindrical protrusion on the other end of the opening and closing shaft is sleeved in the waist-shaped recessed hole of the steel cap adjacent to the other end of the opening and closing shaft.

[0026] The beneficial effect of adopting the above scheme is that the opening and closing shaft is connected to the steel caps on both sides through the cooperation of the waist-shaped recessed hole and the cylindrical protrusion. When the user needs to switch the screen between the open state and the closed state, a force will be applied to the bearing steel plate, and the bearing steel plate drives the opening and closing shaft to rotate in the shaft sleeve. At the same time, the bearing steel plate drives each steel cap to rotate through the cooperation of the waist-shaped recessed hole and the cylindrical protrusion. The rotation of the steel cap further drives the rotation of the side steel bar, thereby realizing the conversion of the screen between the open state and the closed state. Therefore, the opening and closing shaft using the above technology can cooperate with the steel cap and the side steel bar on the bending support assembly to realize the opening or closing of the screen.

[0027] Furthermore, the opening and closing rotating shaft is located at the central position of the bottom edge of the bearing steel plate, and the same number of the bending support components are respectively arranged on both sides of the opening and closing rotating shaft;

[0028] The load-bearing steel plate is also provided with a plurality of middle steel bars, which are located in the middle of the load-bearing steel plate; the middle steel bars and the side steel bars are parallel to the left and right edges of the load-bearing steel plate.

[0029] The beneficial effects of adopting the above scheme are: on the one hand, the same number of bending support components are provided at both ends of the opening and closing shaft, which can make the screen symmetrical in the bent state, and the actual effect is better. On the other hand, the middle steel bar is provided to further improve the overall strength of the screen, ensuring that the strength can be maintained sufficiently when bent or unfolded, especially when the notebook screen is opened and closed in a flat state, the screen will not be distorted. The middle steel bar is welded and fixed to the rear panel of the bearing steel plate, so that the connection between the middle steel bar and the bearing steel plate is more firm, thereby making the state conversion of the screen more reliable.

[0030] Furthermore, the silicone component includes a plurality of double-airbag flushing and deflation components arranged in parallel, gaps are provided between adjacent double-airbag flushing and deflation components, and the closed cavity includes a first strip-shaped airbag and a second strip-shaped airbag arranged in the double-airbag flushing and deflation components;

[0031] The double airbag flushing and deflation assembly includes a first side silicone, a second side silicone, a third side silicone, a fourth side silicone, a fifth side silicone, a top silicone and a bottom silicone; the first strip-shaped airbag is formed between the first side silicone, the second side silicone, the third side silicone, the fourth side silicone, the top silicone and the bottom silicone; the second strip-shaped airbag is formed between the first side silicone, the second side silicone, the fourth side silicone, the fifth side silicone, the top silicone and the bottom silicone;

[0032] The outer contour of the dual airbag flushing and deflation assembly is a rectangular parallelepiped structure arranged along the vertical direction, and the side steel bar is located at the intersection of the first side silicone and the fourth side silicone.

[0033] The beneficial effect of adopting the above scheme is that the double airbag flushing and deflation assembly is an important structure for realizing controllable deformation of the silicone assembly after being stressed. A first strip airbag and a second strip airbag are arranged in the double airbag flushing and deflation assembly. When the air pressure in the first strip airbag and the second strip airbag increases, in two adjacent silicone assemblies, the first strip airbag of the first silicone assembly and the second strip airbag of the second silicone assembly squeeze each other, thereby driving the corresponding steel cap to move.

[0034] Further, in the first strip-shaped airbag, a first protrusion is provided at an angle between the first side silicone and the third side silicone, and a second protrusion is provided at an angle between the first side silicone and the fourth side silicone;

[0035] In the second strip-shaped airbag, a third protrusion is provided at an angle between the first side silicone and the fourth side silicone, and a fourth protrusion is provided at an angle between the first side silicone and the fifth side silicone.

[0036] The beneficial effect of adopting the above solution is that by providing the first protrusion, the second protrusion, the third protrusion and the fourth protrusion, it is possible to further ensure that the silicone component undergoes controlled deformation.

[0037] Further, the first side silicone, the second side silicone, the third side silicone, the fourth side silicone, the fifth side silicone, the top silicone, the bottom silicone, the first raised portion, the second raised portion, the third raised portion and the fourth raised portion are an integrally formed structure.

[0038] The beneficial effect of adopting the above solution is that the one-piece molding method can effectively simplify the structure of the silicone component.

[0039] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0040] A laptop computer comprises a host body and a screen body, wherein the host body is provided with a rotating shaft sleeve, and the screen body is provided with an opening and closing rotating shaft, wherein the opening and closing rotating shaft is rotatably arranged in the rotating shaft sleeve; and the screen body is the above-mentioned flat curved variable OLED screen.

[0041] Compared with the prior art, the beneficial effect of the present technical solution is that through the coordination of the above-mentioned bearing steel plate, OLED display component, silicone component, inflation and deflation component and opening and closing hinge and other structures, not only can a curved screen be equipped on a smaller laptop computer, but the screen can also be converted between a curved surface and a flat surface, thus completing the application of curved screens on high-end laptop computers.

[0062] OLED, Organic Light-Emitting Diode, also known as organic electric laser display, is a phenomenon of luminescence caused by the injection and recombination of carriers, and its luminous intensity is proportional to the injected current. Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, and are injected into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitons are generated, thereby exciting the light-emitting molecules and finally producing visible light. OLED display devices have the advantages of being thinner, lighter and more flexible, and large-size curved screens are one of their important applications.

[0063] The human eyeball has a curvature, and the curvature of the curved screen can ensure that the distance from the eye to the screen is equal, so that the curved screen can bring a better sensory experience. Large-size curved screens can bring better display effects, better surround picture effects, and more prominent layering. In short, compared with flat screens, the sensory experience and display effects of curved screens have been greatly improved. However, large-size curved screens can usually only be used on TVs or desktop monitors, while laptops cannot be equipped with curved screens.

[0064] When a large-size curved screen is used, the display device itself is usually required to have a curved rear shell, which provides a fulcrum to support the curved screen, or a thick rear shell is used to wrap the mechanical structure of the control panel to transform from flat to curved. Generally speaking, the size of a laptop is small, and it is impossible to increase the curved rear shell that can achieve the above function. Therefore, the laptop in the prior art cannot be equipped with a curved screen, and it is even more impossible to achieve the conversion of the screen between a curved surface and a flat surface, which also greatly limits the application of curved screens in high-end laptops.

[0065] like Figure 1 , Figure 2 and Figure 3 As shown, in order to solve the above problems, the present invention provides a flat curved variable OLED screen, which specifically includes a bearing steel plate 1, an OLED display component 2, a silicone component 3, an air charging and discharging component and an opening and closing shaft 4. Wherein, the bearing steel plate 1 can bend and deform after being compressed; the OLED display component 2 is fitted on the front panel of the bearing steel plate 1, and the OLED display component 2 deforms as the bearing steel plate 1 deforms; the silicone component 3 is arranged on the rear panel of the bearing steel plate 1, and a plurality of closed cavities are arranged in the silicone component 3; the air charging and discharging component is connected to the closed cavity, and the air charging and discharging component is used to control the internal air pressure of the closed cavity; the bearing steel plate 1 is directly or indirectly arranged on the opening and closing shaft 4. It should be noted that the bearing steel plate 1 is a plate-like structure, and its two sides are the front panel and the rear panel respectively.

[0066] The OLED display component 2 is arranged on the front panel of the bearing steel plate 1, and the silicone component 3 is arranged on the rear panel of the bearing steel plate 1. The bearing steel plate 1, the OLED display component 2 and the silicone component 3 together constitute the main structure of the screen. Initially, the screen is in a closed state. At this time, the user pulls the screen, and the screen rotates around the opening and closing shaft 4, so that it gradually opens and turns into an open state. When the screen is in an open state, gas is pumped into the closed cavity through the gas filling and discharging component to increase the air pressure in the closed cavity. The increase in air pressure will cause the silicone component 3 to deform, and the silicone component 3 drives the bearing steel plate 1 and then drives the OLED display component 2 to deform, so that the screen bends and turns into a curved state; and when the gas filling and discharging component releases the gas in the closed cavity, the air pressure of the closed cavity is consistent with the external air pressure, and the silicone component 3 returns to its original state. After the bearing steel plate 1 loses the deformation driving force, it also drives the OLED display component 2 to return to its original state, and the screen turns into a flat state. Furthermore, when the screen is not needed, the screen can be opened and closed by flipping the screen so that the screen opening and closing shaft 4 rotates as an axis, thereby gradually turning into a closed state.

[0067] It can be seen that through the coordination of the above-mentioned structures such as the bearing steel plate 1, the OLED display component 2, the silicone component 3, the inflation and deflation component and the opening and closing shaft 4, not only can a curved screen be equipped on a smaller laptop computer, but the screen can also be converted between a curved surface and a flat surface, thus completing the application of curved screens on high-end laptop computers.

[0068] like Figure 4 As shown, preferably, in order to equip a laptop with a curved screen and realize the conversion of the screen between a curved surface and a flat surface, the present invention creatively proposes a bending support assembly 101. Figure 5 and Figure 6 As shown, specifically, a plurality of bending support assemblies 101 are arranged on the bearing steel plate 1 , and each of the bending support assemblies 101 includes a steel cap 102 and a side steel bar 103 , and the side steel bar 103 is arranged on the steel cap 102 .

[0069] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the steel cap 102 is a columnar structure, one end of the steel cap 102 is provided with two waist-shaped recessed holes 104, and the other end of the steel cap 102 is provided with two cylindrical protrusions 105; in two adjacent steel caps 102, the two cylindrical protrusions 105 of one of the steel caps 102 are respectively inserted into the two waist-shaped recessed holes 104 of the other steel cap 102.

[0070] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, when the internal air pressure of the closed cavity increases, the silicone component 3 provides a deformation driving force for the steel cap 102 by deformation, and the two cylindrical protrusions 105 of the steel cap 102 will deviate from the center of the two waist-shaped recessed holes 104 of the other adjacent steel cap 102, and the central axes of the two adjacent steel caps 102 change from overlapping to intersecting, thereby driving the bearing steel plate 1 and the OLED display component 2 to bend, and the OLED display component 2 is converted into a curved state.

[0071] like Figure 5 , Figure 6 , Figure 7 , Figure 8 He Ru Fig.10As shown, when the internal air pressure of the closed cavity decreases, the silicone component 3 returns to its original state, and the silicone component 3 stops providing deformation driving force for the steel cap 102. The bearing steel plate 1 drives the steel cap 102, and the two cylindrical protrusions 105 of the steel cap 102 will return to the center of the two waist-shaped recessed holes 104 of the adjacent steel caps 102. The central axes of the two adjacent steel caps 102 change from intersecting to overlapping, and the bearing steel plate 1 and the OLED display component 2 no longer bend, and the OLED display component 2 is converted into a planar state.

[0072] The key technical solution of the present invention to realize the conversion between the curved surface and the flat surface of the screen is to respectively provide two waist-shaped concave holes 104 and two cylindrical protrusions 105 at both ends of the steel cap 102. Multiple steel caps 102 are connected in sequence, and the two cylindrical protrusions 105 of the previous steel cap 102 are respectively inserted into the two waist-shaped concave holes 104 of the next steel cap 102. Since the cylindrical protrusions 105 are inserted into the waist-shaped concave holes 104, as shown in FIG. Figure 7 and Fig. 9 As shown, in the horizontal waist-shaped concave hole 104, the cylindrical protrusion 105 cannot move in the vertical direction, but can only move left and right in the horizontal direction, which is reflected in the flat curved variable OLED screen, that is, multiple sequentially connected steel caps 102 are always on the same horizontal plane. When the screen is in a flat state, the multiple sequentially connected steel caps 102 are in a straight line, such as Fig.10 When the silicone component 3 expands, it will provide an outward thrust to the steel cap 102. This thrust acts on the steel cap 102, causing the cylindrical protrusion 105 of the steel cap 102 to move horizontally in the waist-shaped concave hole 104. Multiple steel caps 102 connected in sequence are curved, as shown in FIG. Fig. 9 At this time, the multiple steel caps 102 drive the multiple side steel bars 103 to exert force in turn, exert a deformation force on the bearing steel plate 1, and then drive the OLED display component 2 to deform through the bearing steel plate 1, and the screen changes from a flat state to a curved state; and when the silicone component 3 stops expanding, the screen changes from a curved state to a flat state again.

[0073] Therefore, by providing a plurality of steel caps 102 connected in sequence, and each steel cap 102 is provided with a side steel bar 103, combined with the deformation force of the silicone component 3, the screen can be controlled to convert between a flat state and a curved state.

[0074] Preferably, the side steel bar 103 is fixedly arranged on the rear panel of the bearing steel plate 1 by welding. The side steel bar 103 is welded and fixedly arranged on the rear panel of the bearing steel plate 1, so that the connection between the side steel bar 103 and the bearing steel plate 1 is more firm, thereby making the state conversion of the screen more reliable.

[0075] like Figure 8 As shown, the waist-shaped recessed hole 104 includes a first semicircular portion 106, a second semicircular portion 107 and a rectangular transition portion 108; the diameters of the first semicircular portion 106 and the second semicircular portion 107 are equal, the diameters of the first semicircular portion 106 and the second semicircular portion 107 are equal to the width of the rectangular transition portion 108, and the width of the rectangular transition portion 108 is smaller than the length of the rectangular transition portion 108.

[0076] In this technical solution, the waist-shaped recessed hole 104 is the key to realize the conversion between the flat state and the curved state of the screen. Since the steel cap 102 and the side steel bar 103 on the bending support assembly 101 are directly or indirectly arranged on the bearing steel plate 1, and the bearing steel plate 1 itself has a certain resilience, when the resilience acts, it can drive the screen from the curved state to the flat state. When the cylindrical protrusion 105 is inserted into the waist-shaped recessed hole 104 formed by the first semicircular portion 106, the second semicircular portion 107 and the rectangular transition portion 108, under the action of the load-bearing steel plate 1, when there is no external force, the cylindrical protrusion 105 will be in the central position of the rectangular transition portion 108; and after the silicone component 3 provides a deformation force, it will drive the cylindrical protrusion 105 to move in the waist-shaped recessed hole 104; limited by the shape and size of the cylindrical protrusion 105 and the waist-shaped recessed hole 104, when the steel cap 102 is subjected to force, it can only move along the length direction of the rectangular transition portion 108. Fig. 9 and Fig.10 It can be seen that this makes the movement process of two adjacent steel caps 102 specifically that one steel cap 102 rotates with a point on its upper edge as a support point, and the first semicircular portion 106, the second semicircular portion 107 and the rectangular transition portion 108 of the waist-shaped recessed hole 104 reserve space for this rotation process, thereby turning the screen into a curved state.

[0077] Therefore, a waist-shaped recessed hole 104 is formed by the first semicircular portion 106, the second semicircular portion 107 and the rectangular transition portion 108, and a certain rotation space can be reserved in combination with the shape and size of the cylindrical protrusion, so that after the deformation and expansion of the silicone component 3 is controlled by the inflation and deflation components, the screen can eventually be changed into a curved state.

[0078] like Fig. 9 and Fig.10As shown, preferably, the opening and closing shaft 4 is a long strip structure, and the opening and closing shaft can perform reciprocating rotation around its axis to realize the opening and closing function. Two waist-shaped recessed holes are arranged at one end of the opening and closing shaft, and two cylindrical protrusions are arranged at the other end of the opening and closing shaft; the cylindrical protrusion of the steel cap adjacent to one end of the opening and closing shaft is sleeved in the waist-shaped recessed hole at one end of the opening and closing shaft, and the cylindrical protrusion on the other end of the opening and closing shaft is sleeved in the waist-shaped recessed hole of the steel cap adjacent to the other end of the opening and closing shaft.

[0079] The opening and closing shaft 4 is arranged at the center below the bearing steel plate 1, and can rotate with the shaft sleeve arranged on the body, so that the screen can be switched between the open state and the closed state. From the structural point of view, the opening and closing shaft 4 is very similar to the steel cap 102, and two waist-shaped concave holes and two cylindrical protrusions are also arranged at both ends of the opening and closing shaft 4. However, unlike the steel cap 102, the opening and closing shaft 4 is a long strip structure, that is, the length of the opening and closing shaft 4 is greater than the length of the steel cap 102.

[0080] The opening and closing shaft 4 is connected to the steel caps 102 on both sides through the cooperation of the waist-shaped recessed hole 104 and the cylindrical protrusion 105. When the user needs to switch the screen between the open state and the closed state, a force will be applied to the bearing steel plate 1, and the bearing steel plate 1 drives the opening and closing shaft 4 to rotate in the shaft sleeve. At the same time, the bearing steel plate 1 drives each steel cap 102 to rotate through the cooperation of the waist-shaped recessed hole 104 and the cylindrical protrusion 105. The rotation of the steel cap 102 further drives the side steel bar 103 to rotate, thereby realizing the conversion of the screen between the open state and the closed state. Therefore, the opening and closing shaft 4 using the above technology can cooperate with the steel cap 102 and the side steel bar 103 on the bending support assembly 101 to realize the opening or closing of the screen.

[0081] like Figure 4 As shown, specifically, the opening and closing shaft 4 is located at the central position on the bottom edge of the bearing steel plate 1, and the same number of the bending support components 101 are arranged on both sides of the opening and closing shaft 4; a plurality of middle steel bars 109 are also arranged on the bearing steel plate 1, and the plurality of middle steel bars 109 are located in the middle of the bearing steel plate 1; the middle steel bars 109 and the side steel bars 103 are parallel to the left and right edges of the bearing steel plate 1. Specifically, the middle steel bar 109 is fixedly arranged on the rear panel of the bearing steel plate 1 by welding. It should be noted that the middle steel bar 109 is only arranged on the bearing steel plate 1, and is not connected to the opening and closing shaft 4.

[0082] On the one hand, the same number of bending support components 101 are provided at both ends of the opening and closing shaft 4, so that the screen can still be symmetrical in a bent state, and the actual effect is better. On the other hand, the middle steel bar 109 is provided to further improve the overall strength of the screen, ensuring that the strength can be maintained sufficiently when bent or unfolded, especially when the notebook screen is opened and closed in a flat state, the screen will not be distorted. The middle steel bar 109 is welded and fixed to the rear panel of the bearing steel plate 1, so that the connection between the middle steel bar 109 and the bearing steel plate 1 is more firm, thereby making the state conversion of the screen more reliable.

[0083] like Fig.11 and Fig.12 As shown, preferably, the silicone component 3 includes a plurality of double-airbag flushing and deflation components arranged in parallel, gaps are provided between adjacent double-airbag flushing and deflation components, and the closed cavity includes a first strip airbag 301 and a second strip airbag 302 arranged in the double-airbag flushing and deflation components.

[0084] like Fig.13 As shown, specifically, the dual airbag flushing and deflation assembly includes a first side silicone 303, a second side silicone 304, a third side silicone 305, a fourth side silicone 306, a fifth side silicone 307, a top surface silicone and a bottom surface silicone; the first strip airbag 301 is formed between the first side silicone 303, the second side silicone 304, the third side silicone 305, the fourth side silicone 306, the top surface silicone and the bottom surface silicone; the second strip airbag 302 is formed between the first side silicone 303, the second side silicone 304, the fourth side silicone 306, the fifth side silicone 307, the top surface silicone and the bottom surface silicone.

[0085] like Fig.11 and Fig.12 As shown, the outer contour of the dual airbag flushing and deflation assembly is a cuboid structure arranged in the vertical direction, and the side steel bars 103 are located at the intersection of some of the first side silicone rubber 303 and the fourth side silicone rubber 306. Similarly, the middle steel bar 109 is located at the intersection of some of the first side silicone rubber 303 and the fourth side silicone rubber 306.

[0086] The double airbag flushing and deflation assembly is an important structure for realizing controllable deformation of the silicone assembly 3 after force is applied. The first strip airbag 301 and the second strip airbag 302 are arranged in the double airbag flushing and deflation assembly. When the air pressure in the first strip airbag 301 and the second strip airbag 302 increases, in two adjacent silicone assemblies 3, the first strip airbag 301 of the first silicone assembly 3 and the second strip airbag 302 of the second silicone assembly 3 squeeze each other, thereby driving the corresponding steel cap 102 to move.

[0087] like Fig.13 As shown, preferably, in the first strip-shaped airbag 301, a first protrusion 308 is provided at the angle between the first side silicone 303 and the third side silicone 305, and a second protrusion 309 is provided at the angle between the first side silicone 303 and the fourth side silicone 306. In the second strip-shaped airbag 302, a third protrusion 310 is provided at the angle between the first side silicone 303 and the fourth side silicone 306, and a fourth protrusion 311 is provided at the angle between the first side silicone 303 and the fifth side silicone 307. By providing the first protrusion 308, the second protrusion 309, the third protrusion 310 and the fourth protrusion 311, it is possible to further ensure that the silicone component 3 undergoes controlled deformation.

[0088] Preferably, the first side silicone 303, the second side silicone 304, the third side silicone 305, the fourth side silicone 306, the fifth side silicone 307, the top silicone, the bottom silicone, the first protrusion 308, the second protrusion 309, the third protrusion 310 and the fourth protrusion 311 are an integrated structure. The integrated molding method can effectively simplify the structure of the silicone assembly 3.

[0089] In addition, an air pump is also provided on the inflation and deflation assembly. The air pump is integrated into the laptop computer, and is connected to the closed cavity in the silicone assembly 3 through a pipeline and an opening and closing shaft 4. According to user instructions, when the air pump inflates the closed cavity, the air pressure in the closed cavity increases, causing the thinner part of the silicone to bulge, and the bulging silicone squeezes each other, causing the silicone to expand and push the bearing steel plate 1 to bend, while driving the steel cap 102 and the side steel bar 103 to rotate. At this time, the screen is in a curved state, and the OLED display assembly 2 attached to the bearing steel plate 1 is also in the same curved state. The pipeline valve switch is further closed, the air pump is turned off, the screen remains in a curved state, and the automatic bending of the notebook OLED screen is completed. When the screen needs to be turned into a flat state, it is only necessary to release the gas in the closed cavity.

[0090] like Figure 1 and Figure 2As shown, correspondingly, the present invention also provides a laptop computer, including a host body 5 and a screen body 6, wherein the host body 5 is provided with a shaft sleeve, and the screen body 6 is provided with an opening and closing shaft 4, wherein the opening and closing shaft 4 is rotatably provided in the shaft sleeve, and the screen body 6 is the above-mentioned flat curved variable OLED screen. Through the coordination of the bearing steel plate 1, the OLED display component 2, the silicone component 3, the inflation and deflation component, and the opening and closing shaft 4 and other structures, not only can a laptop computer of a smaller size be equipped with a curved screen, but also the conversion of the screen between a curved surface and a flat surface can be realized, thus completing the application of the curved screen on high-end laptop computers.

[0091] In summary, the present invention provides a flat curved variable OLED screen and a laptop computer provided with the flat curved variable OLED screen, wherein the flat curved variable OLED screen specifically comprises a bearing steel plate 1, an OLED display component 2, a silicone component 3, an air-filling and air-discharging component and an opening and closing rotating shaft 4. The bearing steel plate 1 can be bent and deformed after being compressed; the OLED display component 2 is arranged on the front panel of the bearing steel plate 1, and the OLED display component 2 is deformed as the bearing steel plate 1 is deformed; the silicone component 3 is arranged on the rear panel of the bearing steel plate 1, and a plurality of closed cavities are arranged in the silicone component 3; the air-filling and air-discharging component is connected to the closed cavity, and the air-filling and air-discharging component is used to control the internal air pressure of the closed cavity; the bearing steel plate 1 is directly or indirectly arranged on the opening and closing rotating shaft 4. Through the above technical scheme, air pressure is used as the power source for the bending of the screen, and the silicone component 3 of a specific shape is matched, and the silicone component 3 is partially expanded and deformed under air pressure, overcoming the rigidity of the bearing steel plate 1 matched therewith, and realizing structural bending. After the air pressure is released, the silicone component 3 returns to its original state, and the rigidity of the bearing steel plate 1 makes the structure return to straightness. In terms of controlling distortion, a bending support component 101 with a special structure is used to allow two adjacent steel caps 102 to rotate relative to each other. A high-strength side steel bar 103 is connected to one end of the structure. The side steel bar 103 is connected to the bearing steel plate 1 to ensure that the bearing steel plate 1 can only bend in the bending direction of the screen and cannot bend in the direction of opening and closing the screen. The above structure ensures that the screen can maintain a certain strength when bent or unfolded, especially when opening and closing the notebook screen in a flat state, the screen will not be distorted. With this strength, the laptop screen can be opened and closed with the main body, making the laptop thin and easy to carry.

For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
