Description

Technical Field

[0001] The present application relates to the technical field of televisions, and particularly to a rollable display panel and a television. Background Art

[0002] With the development of flexible display panel technology, flexible televisions have gradually come into the public eye. Since they can be rolled up and unfolded, they can reduce the occupied space and save space in home displays; in vehicle-mounted displays, they can install a television as large as possible in the narrow space inside the vehicle to obtain a large-screen display experience. Therefore, flexible televisions have become one of the important development directions in display technology. Currently, there are still certain problems with flexible televisions, that is, when a flexible television is unfolded after being rolled up, unevenness problems caused by bending deformation during rolling often occur on the television screen. These bending deformations will cause deformation of the displayed image, thereby affecting the image display and viewing experience of the television. Summary of the Utility Model

[0003] To solve the above technical problems, the present application discloses a rollable display panel and a television including the display panel. By providing a reinforcing structure layer on the backplane film layer of the display panel, the unevenness problem of bending deformation when the display panel and / or the television is unfolded after being rolled up is avoided, the flatness of the display panel and / or the television is ensured, and thus the image display effect and viewing experience are guaranteed.

[0004] The specific technical solution of the present application is as follows:

[0005] A rollable display panel, comprising: a polarizing film layer, a transparent substrate layer, a transparent anode layer, a light-emitting layer, a metal cathode layer, a backplane film layer, and a reinforcing structure layer, which are sequentially arranged from the display surface to the back surface. The reinforcing structure layer includes a plurality of continuously connected reinforcing units, the reinforcing units are folding plate structures, and the edges of the folding plate structures are arranged at intervals and linearly connected to the backplane film layer.

[0006] The polarizing film layer, the transparent substrate layer, and the backplane film layer of the display panel are all flexible and rollable. By linearly connecting the reinforcing structure layer to the backplane film layer, the reinforcing structure layer is composed of a plurality of continuously connected folding plate structures, which enhances the anti-bending strength of the display panel. The reinforcing structure layer is set as a plurality of continuous folding plate structures, and the anti-bending deformation strength along the extending direction of the folding plate structures is enhanced. The continuously connected folding plate structures can also be rolled up in the direction orthogonal to the structure extending direction. By arranging the folding plate structures on the backplane film layer, the overall anti-bending deformation strength of the display panel is greatly enhanced, thereby improving the flatness of the display panel. At the same time, the display panel can still be rolled up, effectively solving the unevenness problem of bending deformation when the display panel is unfolded after being rolled up.

[0007] Further, the polarizing film layer sequentially includes a linear polarizing film and a circular polarizing film.

[0008] The polarizing film layer can absorb the ambient light incident on the surface of the display panel, reduce the reflection of the ambient light by the display panel, thereby improving the clarity and contrast of the display panel.

[0009] Furthermore, the included angle between the transmission axis of the circular polarizing film and the polarization direction of the transmitted light is 45°; the included angle between the transmission axis of the linear polarizing film and the polarization direction of the transmitted light is 90°.

[0010] Furthermore, the edges of the folding plate structure are parallel to each other.

[0011] The parallel edges of the folding plate structure are conducive to providing a relatively uniform supporting force, ensuring the effective connection between the reinforcing structure layer and the backplane film layer, and maintaining the flatness of the display panel. In particular, for a rollable display panel, it is conducive to uniform winding and storage, and avoids excessive local bending to form creases.

[0012] Furthermore, the reinforcing structure layer includes a number of continuously connected reinforcing units formed by bending a sheet material back and forth.

[0013] Forming the reinforcing structure layer by bending a sheet material back and forth effectively improves the anti-bending deformation strength of the reinforcing structure layer, reduces the weight of the formed reinforcing structure layer, and avoids the influence of the excessive weight of the display panel on installation, transportation, service life, etc.

[0014] Furthermore, the widths of both sides of the reinforcing unit are equal.

[0015] For the continuously connected reinforcing units with equal widths on both sides, the reinforcing units provide balanced anti-bending forces and avoid the influence of the distortion of the reinforcing units themselves on the flatness of the display panel.

[0016] Furthermore, the size coverage range of the reinforcing structure layer is equal to the display area of the display panel.

[0017] The full coverage of the size of the reinforcing structure layer on the display panel can provide a more complete anti-bending support force for the display panel, and avoid local deformation of the display panel where the reinforcing structure layer is not covered locally.

[0018] Furthermore, the height of the reinforcing unit is 5 mm to 20 mm, and the thickness is 4 mm to 10 mm.

[0019] The height and thickness of the reinforcing unit determine the amount of material used and the winding size of the display panel. Therefore, appropriate height and thickness are conducive to cost savings and avoid the excessive size and large space occupation of the display panel after winding.

[0020] A television, comprising the aforementioned display panel, a box body, and a counterweight rod; a reel mechanism and a motor are arranged inside the box body, the reel mechanism includes a winding rod, and the motor is connected to one end of the winding rod; one side edge of the display panel is connected to the winding rod, and the other side edge is connected to the counterweight rod.

[0021] A television, comprising the aforementioned display panel, a base, a lifting mechanism, and an upper crossbeam; a reel mechanism is arranged on the base, the reel mechanism includes a winding rod, the winding rod is connected to one side edge of the display panel, and the other side edge of the display panel is connected to the upper crossbeam; one end of the lifting mechanism is connected to the upper crossbeam, and the other end is connected to the base.

[0022] In this application, by connecting the aforementioned display panel with a motor, a reel mechanism, etc. to form a retractable television, the problem of uneven bending deformation after the television is retracted and unfolded is effectively solved. Description of the Drawings

Detailed implementation mode

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the specific implementation modes.

[0036] Embodiment 1

[0037] Figure 1 It is a schematic structural diagram of the display panel for Embodiment 1. A rollable display panel 10 includes: a polarizing film layer 101, a transparent substrate layer 102, a transparent anode layer 103, a light-emitting layer 104, a metal cathode layer 105, a backplane film layer 106, and a reinforcing structure layer 107 arranged in sequence from the display surface to the back surface.

[0038] Figure 2 It is a schematic diagram of the shape of the reinforcing structure layer for Embodiment 1, Figure 3 It is a schematic diagram of the connection between the reinforcing structure layer and the backplane film layer for Embodiment 1. The reinforcing structure layer 107 includes a number of continuously connected reinforcing units 200 ( Figure 2 the part within the dashed box in the figure), the reinforcing unit 200 is a folded plate structure, and the edges 201 of the folded plate structure are arranged at intervals and linearly connected to the backplane film layer 106.

[0039] Further explanation, the polarizing film layer 101, the transparent substrate layer 102, the backplane film layer 106, etc. of the display panel 10 are all flexible and rollable. By linearly connecting a reinforcing structure layer 107 composed of a number of continuously connected folded plate structures on the backplane film layer 106, the bending resistance of the display panel 10 is enhanced. The reinforcing structure layer is set as a number of continuous folded plate structures, and the bending deformation resistance in the extending direction of the folded plate structure is enhanced. The continuously connected folded plate structures can also be wound in the direction orthogonal to the structure extending direction. By setting the folded plate structure on the backplane film layer 106, the overall bending deformation resistance of the display panel 10 is greatly enhanced, thereby improving the flatness of the display panel. At the same time, the display panel 10 can also be wound, effectively solving the problem of uneven bending deformation after the display panel 10 is wound and unfolded.

[0040] Furthermore, the polarizing film layer 101 sequentially includes a linear polarizing film and a circular polarizing film.

[0041] Figure 4 Schematic diagram of the relationship between the transmission axis of each component of the polarizing film layer and the polarization direction of the transmitted light in Example 1. Figure 4 As shown in Figure a, with o as the origin, the transmission axis direction of the circular polarizing film is in the oy direction, the polarization direction of the transmitted light is in the oc direction, and the angle between the transmission axis direction of the circular polarizing film and the polarization direction of the transmitted light is preferably 45°; Figure 4 As shown in Figure b, with o as the origin, the transmission axis direction of the linear polarizing film is the ov direction, the polarization direction of the transmitted light is the oz direction, and the angle between the transmission axis direction of the linear polarizing film and the polarization direction of the transmitted light is preferably 90°.

[0042] After passing through the 90° linear polarizing film, the ambient light is converted into 90° linear polarized light and transmitted. After passing through the 45° circular polarizing film, since the circular polarizing film is composed of a linear polarizing film and a phase retarder, it is converted into 135° linear polarized light and transmitted. The light is then reflected back to the 45° circular polarizing film by the metal cathode layer 105, converted into 180° linear polarized light and transmitted. Finally, the 180° linear polarized light that has passed through the circular polarizing film is incident on the 90° linear polarizing film. Since the 180° linear polarized light is orthogonal to the transmission axis of the 90° linear polarizing film, it cannot pass through and is absorbed by the linear polarizing film. The ambient light that is incident on the display panel surface is then absorbed by the polarizing film layer 101. Therefore, providing the polarizing film layer 101 on the surface of the display panel 10 can reduce the reflection of ambient light by the display panel 10, thereby improving the clarity and contrast of the display panel 10.

[0043] Furthermore, the transparent substrate layer 102 can be a flexible film or a flexible sheet, and its material can be a combination of one or more transparent resin materials such as polyacrylate, polyethylene terephthalate, fluorinated polymer, polyethylene naphthalate, polyparaxylene, polycarbonate, polyimide, etc.

[0044] Furthermore, the transparent anode layer 103 may be made of materials such as polyaniline, gold, indium tin oxide, zinc oxide, etc., which can transmit light and absorb electrons to form holes.

[0045] Furthermore, the light-emitting layer 104 can be polyphenylene vinylene, polythiophene, or fluorescent or phosphorescent dyes or pigments. The electrons provided by the cathode and the holes provided by the anode meet in the light-emitting layer 104 and excite the fluorescent dye or phosphorescent dye, thereby radiating and emitting light.

[0046] Further, the metal cathode layer 105 can be composed of a single layer of metals such as gold (Au), silver (Ag), aluminum (Al), lithium (Li), magnesium (Mg), calcium (Ca), indium (In), etc.; it can also be composed of multi-layer alloys such as an alloy of magnesium (Mg) and silver (Ag), and an alloy of lithium (Li) and aluminum (Al). The metal cathode layer 105 can emit electrons and can also serve as a reflective layer to reflect light out of the panel.

[0047] Further, the backplane film layer 106 can be a flexible thin film or a flexible sheet, and its material can be a combination of one or more of transparent resin materials such as polyacrylate, polyethylene terephthalate, fluorinated polymer, polyethylene naphthalate, parylene, polycarbonate, polyimide, etc.

[0048] Further, between the transparent anode layer 103 and the light-emitting layer 104, a hole transport layer can also be included; between the light-emitting layer 104 and the metal cathode layer 105, an electron transport layer can also be included. By the convergence of holes by the hole transport layer and the convergence of electrons by the electron transport layer, the transport efficiency of holes and electrons is improved, thereby improving the light-emitting efficiency of the display panel 10.

[0049] Further, a hole injection layer can also be included between the transparent anode layer 103 and the hole transport layer, and an electron blocking layer can also be included between the hole transport layer and the light-emitting layer 104; an electron injection layer can also be included between the metal cathode layer 105 and the electron transport layer, and a hole blocking layer can also be included between the electron transport layer and the light-emitting layer 104. The hole injection layer can smoothly inject holes into the hole transport layer, the hole transport layer transports the holes to the light-emitting layer, and the electron blocking layer can block electrons at the interface of the light-emitting layer, increasing the electron concentration at the interface of the light-emitting layer; the electron injection layer can smoothly inject electrons into the electron transport layer, the electron transport transports the electrons to the light-emitting layer, and the hole blocking layer blocks the holes at the interface of the light-emitting layer, improving the combination probability of holes and electrons at the interface of the light-emitting layer, thereby increasing the light-emitting efficiency of the display panel.

[0050] Further, the material of the hole injection layer can be evaporated silicon dioxide, lithium fluoride, etc.; the material of the electron injection layer can be lithium oxide, potassium silicate, lithium fluoride, etc.; the material of the hole transport layer can be a triarylamine compound; the material of the electron transport layer can be an aromatic compound such as 1,3,4-diazole or 1,2,4-triazole; the material of the electron blocking layer can be aluminum indium nitride and aluminum gallium nitride, etc.; the material of the hole blocking layer can be 3,5-tri(N-phenyl-2-benzimidazole)benzene or magnesium oxide-doped tin oxide quantum dots.

[0051] Figure 5Schematic diagram of the folded plate structure of Embodiment 1. All the edges 201 of the folded plate structure in the reinforcing structure layer 107 are parallel to each other. The edges 201 of the folded plate structure are distributed on two opposite surfaces of the reinforcing structure layer 107. Here, the parallelism of the edges 201 of the folded plate structure can mean that the edges 201 of the folded plate structure in the same surface of the reinforcing structure layer 107 are parallel to each other, as shown in the surface indicated by the arrow direction in Figure a of Figure 5 ; it can also mean the parallelism of the edges 201 of the folded plate structure in space, as shown in Figure b of Figure 5 . In this case, the edges 201 of the folded plate structure are not completely in the same surface of the reinforcing structure layer 107, and at this time, the edges are parallel to each other in space.

[0052] For further explanation, the parallelism of the edges 201 of the folded plate structure is beneficial to bending and providing a relatively uniform supporting force, ensuring the effective connection between the reinforcing structure layer 107 and the backplane film layer 106, and maintaining the flatness of the display panel 10. In particular, for the rollable display panel 10, it is beneficial to uniformly wind and store, and avoid excessive local bending to form creases.

[0053] Figure 6 Schematic diagram of the formation of the reinforcing structure layer of Embodiment 1. The reinforcing structure layer 107 includes a number of continuously connected reinforcing units 200 formed by folding a sheet 20 back and forth. After the sheet 20 is folded back and forth to form the reinforcing structure layer 107, the structure of the formed reinforcing unit 200 itself has strong resistance to bending deformation, and the interaction between the continuously connected reinforcing units 200 further enhances the bending deformation resistance strength. By folding the sheet to form the reinforcing structure layer 107, its structural shape can be hollow. Such a setting can reduce the weight of the formed reinforcing structure layer 107 and avoid the influence on installation, transportation, service life, etc. caused by the overweight of the display panel 10.

[0054] For further explanation, the back-and-forth folding process of the sheet 20 is as follows: Determine a position P on the sheet 20, and then set a position u at a certain distance from the position P. At the position P, fold the sheet 20 in one direction, and at the position P, fold the sheet 20 in the opposite direction. In this way, the sheet is continuously and alternately folded in two opposite directions at a certain interval to form the reinforcing structure layer. The so-called back-and-forth folding in this application refers to two opposite directions, and does not specifically refer to which direction is positive or negative.

[0055] Furthermore, the material of the sheet can be plastic materials such as polyethylene terephthalate, polycarbonate, and polymethyl methacrylate. The rolled plastic material can be continuously folded and then cut into the size of the display panel, and bonded to the backplane film layer by gluing; or a single plastic material can be continuously folded and then bonded to the backplane film layer.

[0056] Further, any adjacent reinforcement units 200 can be connected by a connecting member. The cross-sectional shape of the connecting member can be linear, arc-shaped, etc. That is to say, the reinforcement units 200 are not isolated from each other, but are connected by the connecting member to form a whole, thereby realizing the continuity of the reinforcement structure layer 107, avoiding the separation of the reinforcement unit 200 from the display panel 10 due to the shaking / twisting of the reinforcement unit 200, and thus maintaining the long-term stable connection between the display panel 10 and the reinforcement structure layer 107, and the flatness of the connection between the reinforcement structure layer 107 and the display panel.

[0057] Figure 7 Schematic diagram of the side dimensions of the reinforcement unit in the first embodiment. The widths w of the sides 202 of the same reinforcement unit 200 are equal. The continuously connected sides with equal widths can enable the folded plate structure to provide balanced bending resistance and avoid the influence of the distortion of the folded plate structure itself on the flatness of the display panel.

[0058] For further explanation, the equal widths of the sides 202 of the reinforcement unit here can be, as shown in Figure 7 Figure a, the widths w of the sides 202 of all the reinforcement units 200 on the reinforcement structure layer 107 are equal; it can also be, as shown in Figure 7 Figure b, the widths w of the sides 202 of different reinforcement units 200 on the reinforcement structure layer 107 are not completely equal, and only the widths of the two sides of the reinforcement unit itself are equal.

[0059] Figure 8 Schematic diagram of the dimensions of the reinforcement structure layer and the display panel in the first embodiment. The length L and width K dimensions of the reinforcement structure layer 107 are equal to the length and width dimensions of the display panel, that is, the dimensions of the reinforcement structure layer 107 completely cover the dimensions of the display panel 10. By comprehensively covering the display panel 10 with the dimensions of the reinforcement structure layer 107, more complete bending resistance support force can be provided to each position of the display panel 10, avoiding local deformation of the display panel area without the covered reinforcement structure layer.

[0060] Figure 9 Schematic diagram of the dimensions of the reinforcement unit in the first embodiment. The height D of the reinforcement unit 200 is 5 mm to 20 mm, and the thickness d is 4 mm to 10 mm. It can be known that the height D and thickness d of the reinforcement unit 200 can determine the amount of material used, the forming difficulty, the bending deformation strength of the formed reinforcement structure layer, and the winding size of the display panel. Therefore, on the premise of meeting the bending strength of the reinforcement structure layer 107, appropriate height and thickness are beneficial to saving costs and avoiding the display panel having too large a size after winding and occupying a large space.

[0061] After research, when the height D of the reinforcing unit is less than 5 mm and the thickness d is less than 4 mm, the difficulty of forming the reinforcing structure layer will increase significantly, and the anti-bending deformation strength of the formed reinforcing structure layer is small, which is not conducive to resisting the bending deformation after the display panel is wound. When the height D is greater than 20 mm and the thickness d is greater than 10 mm, both the material usage and the winding size of the display panel increase significantly. The significant increase in material usage results in an overweight display panel, and the too-large winding size is not conducive to the packaging, transportation, and installation of the display panel, and will also reduce the service life of the display panel.

[0062] Furthermore, the height D of the reinforcing unit can gradually decrease / increase along one direction, and the thickness d can gradually increase / decrease along one direction. In addition, the height D and thickness d of the reinforcing unit can also change in the following ways: the height D shows a trend change along one direction while the thickness d remains unchanged; the thickness d shows a trend change along one direction while the height D remains unchanged.

[0063] Furthermore, on the side of the reinforcing structure layer away from the display surface of the display panel, a protective film layer can be provided to cover the reinforcing structure layer. When the display panel is wound or unwound, the protective film layer is wound or unwound together, which can prevent the reinforcing structure layer from scratching the display surface during the winding and unwinding process.

[0064] Embodiment 2

[0065] Figure 10 Schematic diagram of the TV for Embodiment 2. Figure 10 In Figure a, it is the unfolded state diagram of the TV. The TV 50 includes the display panel 10, the box body 30, and the counterweight rod 40 of Embodiment 1. A reel mechanism 302 and a motor 301 are provided in the box body 30. The reel mechanism 302 includes a winding rod 3021, and the motor 301 is connected to one end of the winding rod 3021. One side edge of the display panel 10 is connected to the winding rod 3021, and the other side edge of the display panel 10 is connected to the counterweight rod 40.

[0066] Here, the display panel 10 is rollable, which is conducive to the winding and unwinding of the TV. When needed, it can be unfolded for viewing, and when not needed, it can be wound up.

[0067] A winding rod 3021 and a motor 301 are provided in the box body 30. The motor 301 is connected to one end of the winding rod 3021. The motor 301 provides power for the winding and unwinding of the entire TV. By controlling the motor 301 to drive the rotation of the winding rod 3021, the control of the winding and unwinding of the TV is realized. One side edge of the display panel 10 is connected to the winding rod 3021, and the winding rod 3021 is mainly used for the winding and unwinding operations of the display panel 10. The other side edge of the display panel 10 is connected to the counterweight rod 40, and the counterweight rod 40 provides corresponding gravity for the unfolding of the display panel 10, so that the display panel 10 is flattened in the vertical direction.

[0068] The outer shape of the box body 30 can be square, circular, polygonal, etc. Its decorative edge (cover) is generally only used for concealed or embedded products, and its shape can be "L"-shaped, "T"-shaped, or irregular. The connection of each part in the box body 30 can be achieved by means such as screws, buckles, and welding. The winding rod 3021 can use different involute structure reels to improve the height difference problem at the connection between the winding rod 3021 and the display panel 10, and the height of the involute can be changed according to the actual situation. The counterweight rod 40 has the function of decorative counterweight, and its shape is not unique. The cross-section can be trapezoidal, rectangular, or circular. The material of the counterweight rod 40 can be selected from metal materials such as iron and stainless steel. Small steps can be added to the end cover of the counterweight rod 40 to limit the wound display panel and block the gap. The connection method between the winding rod 3021, the counterweight rod 40, and the display panel 10 can be any one of bonding, pressing with a strip, buckling, etc.

[0069] When installed on the wall or mounted on the roof of a vehicle, the counterweight rod 40 can also be fixed by magnetic attraction or Velcro. For example, one or more pairs of magnetic attraction devices can be installed. In this way, it is possible to prevent the lower end of the display panel from being affected by wind or slight external force and shaking.

[0070] Figure 10 Figure b in the middle is the winding state diagram of the TV 50. The display panel 10 is wound into a cylindrical shape in the box body 30, and the entire display panel 10 is accommodated in the box body 30, greatly reducing the occupied space and facilitating storage and transportation. When not in use, the display panel 10 can be stored and hidden in the box body 30, which not only improves the aesthetic appearance but also enhances the convenience of TV transportation, is conducive to the popularization and application of the retractable TV, and greatly expands the application scenarios. When winding, starting from the winding rod 3021, the display surface of the display panel 10 is placed on the inner side of the winding (close to the winding rod 3021), and the reinforcement structure layer 107 is placed on the outer side of the winding. It is wound layer by layer. Outward along the winding rod 3021, there are successively the display surface of the display panel 10, the reinforcement structure layer 107, the display surface of the display panel 10, the reinforcement structure layer 107... The outermost layer is the reinforcement structure layer 107.

[0071] Furthermore, auxiliary sections can also be provided on both sides of the display panel 10, and the display panel 10 is connected to the winding rod 3021 and the counterweight rod 40 through the auxiliary sections. In this way, the display panel 10 is not directly connected to the winding rod 3021 and the counterweight rod 40, which can further reduce the size of the display panel 10 and the overall weight of the TV, and is beneficial to packaging, transportation, and installation.

[0072] Furthermore, the auxiliary sections are also made of retractable materials, which can be the same as the material of the backplane film layer 106. Since the auxiliary sections are not used for display, an enhancement structure layer 107 can be provided on the auxiliary sections, or the enhancement structure layer 107 can not be provided.

[0073] By connecting the display panel of Embodiment 1 with a motor, a reel mechanism, etc., the present application effectively solves the problem of uneven bending deformation after the TV is unrolled.

[0074] Embodiment 3

[0075] Figure 11 It is a schematic diagram of the TV in Embodiment 3, where Figure 11 Figure 1-1 is the unfolded state diagram of the TV, Figure 1-2 is the partial enlarged view of position A in Figure 1-1, and Figure 1-3 is the rolled-up state diagram of the TV.

[0076] TV ५०, including the display panel १० of Embodiment 1, the base ६०, the lifting mechanism ६०१ and the upper crossbeam ६०२; a reel mechanism ३०२ is arranged on the base ६०, and the reel mechanism ३०२ includes a winding rod ३०२१, the winding rod ३०२१ is connected to one side edge of the display panel १०, and the other side edge of the display panel १० is connected to the upper crossbeam ६०२; one end of the lifting mechanism ६०१ is connected to the upper crossbeam ६०२, and the other end is connected to the base ६०.

[0077] Further explanation, the shape of the base ६० can be square, circular or polygonal, etc. Its decorative edge (cover) is generally only used for hidden or embedded products, and its shape can be "L" shape, "T" shape, special shape. A winding rod ३०२१ is arranged on it, and the winding rod ३०२१ is connected to one side edge of the display panel. The winding rod ३०२१ is mainly used for winding the display panel. The winding rod ३०२१ cooperates with the lifting mechanism ६०१ to control the lifting of the display panel; the other side edge of the display panel is connected to the upper crossbeam ६०२, and the upper crossbeam ६०२ provides an upward tensile force for the display panel.

[0078] Furthermore, the winding rod ३०२१ can use different involute structure reels to improve the height difference problem at the connection between the winding rod ३०२१ and the display panel. The involute can change the height according to the actual situation. The upper crossbeam ६०२ also has a decorative function, and its shape is not unique. The cross-section can be trapezoidal, rectangular or circular. The material of the upper crossbeam ६०२ can be selected from metal materials such as iron and stainless steel. The end cover of the upper crossbeam ६०२ can add a small step to limit the rolled-up display panel and block the gap. The connection method between the winding rod ३०२१, the upper crossbeam ६०२ and the display panel can be any one of bonding, pressing with a strip, buckling, etc.

[0079] Furthermore, one end of the lifting mechanism ६०१ is connected to the upper crossbeam ६०२ to control the upward movement of the upper crossbeam ६०२, thereby providing an upward acting force for the unfolding of the display panel. The other end is connected to the base ६०, so that it is convenient to contract the display panel into the base.

[0080] Further, the main function of the lifting mechanism 601 is to unfold the display panel and support the display surface to stand upright. The lifting mechanism 601 can be formed by combining parts such as a flexure arm and a telescopic rod, and the whole can present a V shape.

[0081] In addition, the reel mechanism 302 can also include a motor (not shown in the figure) that matches the winding rod 3021. The motor provides power for the winding and unwinding of the entire retractable TV, and controls the movement of the winding rod 3021 and the lifting structure 601 by controlling the motor, thereby realizing the control of the winding and unwinding of the TV.

[0082] Here, the display panel is retractable, which is beneficial to the winding and unwinding of the TV. When needed, it can be unfolded for viewing, and when not needed, it can be wound up.

[0083] In Figure 11 In FIGS. 1-3, the display panel 10 is wound into a cylindrical shape in the base 60. The entire display panel is housed in the base, greatly reducing the occupied space and facilitating storage and transportation. When not in use, it can be stored and hidden in the base, improving the aesthetics and the convenience of transportation, which is conducive to the popularization and application of the retractable TV and greatly expands the application scenarios. When winding up, starting from the winding rod, the display surface of the display panel is placed on the inner side of the winding (close to the winding rod), and the reinforcing structure layer is placed on the outer side of the winding. It is wound layer by layer. Outward along the winding rod, there are the display surface of the display panel, the reinforcing structure layer, the display surface of the display panel, the reinforcing structure layer... The outermost layer is the reinforcing structure layer.

[0084] Further, when the TV of this embodiment is installed in a vehicle, the base can be installed on the roof of the vehicle. In this way, when the TV needs to be viewed, it can be unfolded downward from the roof, and after winding up, the TV can be hidden in the roof without occupying the interior space of the vehicle. Of course, the TV can also be hidden and installed under the vehicle floor. When the TV needs to be viewed, it can be raised from the vehicle floor, also without occupying the interior space of the vehicle.

[0085] Further, auxiliary sections can be provided on both sides of the display panel. The auxiliary sections are connected to the winding rod and the counterweight bar, so that the display panel is not directly connected to the winding rod and the counterweight bar, which can further reduce the size of the display panel and the overall weight of the TV, and is beneficial to packaging, transportation and installation.

[0086] Further, the auxiliary section is also made of retractable material, which can be the same as the material of the backplane film layer. Since the auxiliary section is not used for display, a reinforcing structure layer can be provided on the auxiliary section, or it can be not provided.

[0087] In this application, the display panel of Embodiment 1 is connected to the base, the lifting structure, the upper cross beam, etc. to form a retractable TV, effectively solving the problem of uneven bending deformation after the TV is wound up and unfolded.

[0088] The above are only the preferred embodiments of the present utility model. It should be noted that the above preferred embodiments should not be construed as limiting the present utility model, and the protection scope of the present utility model should be subject to the scope defined by the claims. For those of ordinary skill in the art of this technology, without departing from the spirit and scope of the present utility model, several improvements and modifications can also be made, and these improvements and modifications should also be regarded as within the protection scope of the present utility model.
