Description

Technical Field

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

[0002] With the development of flexible display panel technology, flexible televisions have gradually entered the public eye. Since they can be rolled up and unfolded, in home displays, they can reduce the occupied space and save space; 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 also 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 up 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 ensured.

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

[0005] A rollable display panel includes: 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 sequentially arranged from the display surface to the back surface. The reinforcing structure layer includes a plurality of continuously connected reinforcing units, and the reinforcing unit is an arc-shaped plate strip structure. The tops of the arc-shaped plate strip structures are distributed at intervals and connected to the backplane film layer.

[0006] The polarizing film layer, the transparent substrate layer, and the backplane film layer are all flexible and rollable. By linearly connecting the reinforcing structure layer on the backplane film layer, the reinforcing structure layer includes a plurality of continuously connected arc-shaped plate strip structures, which enhances the anti-bending strength of the display panel. The reinforcing structure layer is set as a plurality of continuous arc-shaped plate strip structures, and the anti-bending deformation strength along the extending direction of the arc-shaped plate strip structure is enhanced. Moreover, the continuously connected arc-shaped plate strip structures can also be rolled up in the direction orthogonal to the structure extending direction. By arranging the arc-shaped plate strip 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, and thus improve the clarity and contrast of the display panel.

[0009] Further, 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] Further, the top extension directions of the arc-shaped strip structures are parallel to each other.

[0011] The top extension directions of the arc-shaped strip structures being parallel to each other is beneficial to providing a relatively uniform supporting force, ensuring the effective connection between the reinforcement structure layer and the backplane film layer, and maintaining the flatness of the display panel. In particular, for a rollable display panel, it is beneficial to uniformly wind and store it, and avoid excessive local bending to form creases.

[0012] Further, any adjacent ones of the reinforcement units are connected by an inverted arc-shaped strip structure.

[0013] The transition connection between any adjacent two reinforcement units is realized through the inverted arc-shaped strip structure, maintaining the stability of the reinforcement units. The continuity of the reinforcement structure is realized by the alternating connection of the reinforcement units and the inverted arc-shaped strip structure, avoiding the shaking / twisting between the reinforcement units, maintaining the long-term stability of the reinforcement structure layer, and thus maintaining the flatness of the supported display panel.

[0014] Further, any adjacent ones of the reinforcement units are connected by a straight plate.

[0015] Setting a straight plate connection between any adjacent ones of the reinforcement units is beneficial to simplifying the connection difficulty between adjacent reinforcement units.

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

[0017] The size of the reinforcement structure layer fully covers the display panel, and can provide a more complete anti-bending supporting force to the display panel, avoiding local deformation of the display panel where the reinforcement structure layer is not covered locally.

[0018] Further, the height of the reinforcement unit is 4 mm to 20 mm, and the thickness is 2 mm to 10 mm.

[0019] The height and thickness of the reinforcement unit determine the amount of material used and the winding size of the display panel. Therefore, appropriate height and thickness are beneficial to cost savings and avoid the display panel having too large a size and occupying too much space after being wound.

[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 to 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 manners

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

[0036] Embodiment 1

[0037] Figure 1 As a schematic structural diagram of the display panel for Embodiment 1, a retractable 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, which are sequentially arranged from the display surface to the back surface.

[0038] Figure 2 As a schematic structural diagram of the reinforcing structure layer for Embodiment 1, Figure 3 As 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 plurality of continuously connected reinforcing units 200 ( Figure 2 the part within the dashed box in the figure), and the reinforcing unit 200 is an arc-shaped plate strip structure. The tops 201 of the arc-shaped plate strip structures are spaced apart and connected to the backplane film layer 106.

[0039] Furthermore, the top 201 of the arc-shaped plate strip structure may refer to the top edge of the arc-shaped part on each reinforcing unit 200; it may also refer to the edge line of the connected part between adjacent reinforcing units 200. Therefore, the tops 201 of the arc-shaped plate strip structures on the reinforcing structure layer 107 are spaced apart, so that the connection between the top 201 of the arc-shaped plate strip structure and the backplane film layer 106 is a line contact. Compared with a surface contact, a flatter support surface can be obtained.

[0040] To further explain, the polarizing film layer 101, transparent substrate layer 102, and backplane film layer 106 of the display panel 10 are all flexible and rollable. By linearly connecting a reinforcing structural layer 107 composed of a continuously connected curved strip-like structure to the backplane film layer 106, the display panel 10's bending strength can be enhanced. The curved strip-like structure improves the resistance to bending deformation along the direction in which the curved strip-like structure extends. The continuously connected curved strip-like structure can also be rolled up in a direction orthogonal to the structure's extension direction. By placing the curved strip-like structure on the backplane film layer 106, the overall resistance to bending deformation of the display panel 10 is greatly enhanced, thereby improving the display panel's flatness. This configuration of the display panel 10 also allows for rollability, effectively addressing the unevenness of the display panel when it is rolled up and then unfolded.

[0041] Furthermore, the polarizing film layer 101 includes a linear polarizing film and a circular polarizing film in sequence.

[0042] 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 the oy direction, the polarization direction of the transmitted light is 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 45°, which is the best; 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 best angle between the transmission axis direction of the linear polarizing film and the polarization direction of the transmitted light is 90°.

[0043] 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.

[0044] 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.

[0045] Further, the transparent anode layer 103 can be made of materials such as polyaniline, gold, indium tin oxide, zinc oxide, etc., which can transmit light and absorb electrons to form holes.

[0046] Further, the light-emitting layer 104 can be poly(phenylacetylene), polythiophene, or dyes and pigments with fluorescence or phosphorescence. Electrons provided by the cathode and holes provided by the anode meet in the light-emitting layer 104, exciting the fluorescent dye or phosphorescent dye, thereby radiating to form light and emitting it.

[0047] 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 a multi-layer alloy such as an alloy of magnesium (Mg) and silver (Ag), or an alloy of lithium (Li) and aluminum (Al). The metal cathode layer 105 can emit electrons and can also act as a reflective layer to reflect light out of the panel.

[0048] Further, the backplane film layer 106 can be a flexible thin film or a flexible sheet, and its material can be one or a combination of transparent resin materials such as polyacrylate, polyethylene terephthalate, fluoropolymer, polyethylene naphthalate, parylene, polycarbonate, polyimide, etc.

[0049] 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.

[0050] 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 enable holes to be smoothly injected 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 enable electrons to be smoothly injected into the electron transport layer, the electron transport transports the electrons to the light-emitting layer, and the hole blocking layer blocks 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.

[0051] Furthermore, the material of the hole injection layer can be vapor-deposited 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 indium aluminum 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.

[0052] Figure 5 Schematic diagram of the arc-shaped plate strip structure of Example 1. The extending directions of the tops 201 of the arc-shaped plate strip structures on the reinforcement unit 200 are parallel to each other. The tops 201 of the arc-shaped plate strip structures are distributed on two opposite surfaces of the reinforcement structure layer. Here, the tops 201 of the arc-shaped plate strip structures being parallel to each other can mean that the tops 201 of the arc-shaped plate strip structures in the same surface of the reinforcement structure layer 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 that the tops 201 of the arc-shaped plate strip structures are parallel to each other in space, as shown in Figure b of Figure 5 . The tops 201 of the arc-shaped plate strip structures are not completely in the same surface of the reinforcement structure layer. At this time, the edges are parallel to each other in space.

[0053] Further explanation, the tops 201 of the arc-shaped plate strip structures being parallel to each other is beneficial for bending and providing a relatively uniform supporting force, ensuring the effective connection between the reinforcement 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 for uniform winding and storage, and avoiding excessive local bending to form creases.

[0054] Figure 6 Schematic diagram of one shape of the reinforcement structure layer of Example 1; Figure 7 Schematic diagram of another shape of the reinforcement structure layer of Example 1.

[0055] Any adjacent reinforcement units 200 are connected by an inverted arc-shaped plate strip structure 202 ( Figure 6 the part within the dotted line box in ). The inverted arc-shaped plate strip structure 202 realizes the transitional connection of any adjacent reinforcement units 200, and maintains the stability of the reinforcement units 200. The continuity of the reinforcement structure is realized by the alternating connection of the reinforcement units and the inverted arc-shaped plate strip structure, avoiding the shaking / twisting between the reinforcement units, maintaining the long-term stability of the reinforcement structure, and thus maintaining the flatness of the display panel 10.

[0056] For further explanation, the height and thickness dimensions of the arc-shaped strip structure on the reinforcement structure layer 107 can be exactly the same as those of the inverted arc-shaped strip structure; the height and thickness dimensions of the arc-shaped strip structure on the reinforcement structure layer and those of the inverted arc-shaped strip structure can also be not completely the same. The definitions of the height and thickness dimensions here are the same as those of the height and thickness dimensions of the reinforcement unit in the following text.

[0057] Further, after bending the sheet in one direction, at a position at a certain distance from the bending position, then bend the sheet in the opposite direction. In this way, by continuously and alternately bending the sheet in two opposite directions at a certain interval, the reinforcement structure layer is formed.

[0058] Further, the sheet material can be plastic materials such as polyethylene terephthalate, polycarbonate, and polymethyl methacrylate. The rolled plastic material can be continuously bent and then cut into the size of the display panel, and bonded to the backplane film layer by means of adhesion; or a single plastic sheet can be continuously bent and then bonded to the backplane film layer.

[0059] Any adjacent reinforcement units 200 can also be connected by a straight plate 203. Setting a straight plate 203 to connect between any adjacent reinforcement units 200 is beneficial to simplifying the connection difficulty between adjacent reinforcement units.

[0060] Figure 8 It is a schematic diagram of the size of the reinforcement structure layer and the display panel in Embodiment 1. 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 size of the reinforcement structure layer 107 completely covers the size of the display panel 10. By comprehensively covering the display panel 10 with the size of the reinforcement structure layer 107, more complete anti-bending support force can be provided to each position of the display panel 10, and local deformation of the display panel where the reinforcement structure layer is not covered locally can be avoided. Here, an example is given where the reinforcement structure layer 107 is set as a structure shape of an arc-shaped strip structure connected to an inverted arc-shaped strip structure. Of course, the reinforcement structure layer can also be set as a structure shape of an arc-shaped strip structure connected to a straight plate; it can also be set as a structure shape of continuous connection of arc-shaped strip structures.

[0061] Figure 9 It is a schematic diagram of the size of the reinforcement unit in Embodiment 1. The height D of the reinforcement unit 200 is 4 mm to 20 mm, and the thickness d is 2 mm to 10 mm. As Figure 9 shown in Figure a, the reinforcement structure layer 107 is composed of continuously connected arc-shaped strip structures. By measuring any arc-shaped strip structure, the height and thickness of the reinforcement unit can be obtained; and as Figure 9As shown in Figure b of the Chinese version, the reinforcing structure layer 107 is composed of a connection between an arc-shaped plate strip structure and an inverted arc-shaped plate strip structure. At this time, half of the thickness on the side of the reinforcing structure is used as the thickness of the reinforcing unit, and then the height measured at this time is the height of the reinforcing unit. It can be known that the height D and thickness d of the reinforcing unit 200 can determine the amount of material used, the forming difficulty, the anti-bending deformation strength of the formed reinforcing structure layer, and the winding size of the display panel. Therefore, on the premise of meeting the anti-bending strength of the reinforcing structure layer, appropriate height and thickness are beneficial to cost savings and avoiding excessive size of the display panel after winding, which takes up a large amount of space.

[0062] After research, when the height D of the reinforcing unit is less than 4 mm and the thickness d is less than 2 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 of the display panel after winding; while 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 over-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.

[0063] Furthermore, the height D of the reinforcing unit can gradually decrease / increase along one direction, and the thickness d gradually increases / decreases 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.

[0064] Furthermore, on the side of the reinforcing structure layer away from the display surface of the display panel, a protective film layer can also 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.

[0065] Embodiment 2

[0066] Figure 10 It is a schematic diagram of a TV for Embodiment 2. Figure 10 Figure a in the Chinese version is an unfolded state diagram of the TV. The TV 50 includes the display panel 10, the box body 30, and the counterweight rod 40 described in Embodiment 1; a reel mechanism 302 and a motor 301 are provided inside 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.

[0067] Here, the display panel 10 is rollable, which is beneficial for the winding and unwinding of the TV. When needed, it can be unfolded for viewing, and when not needed, it can be wound up.

[0068] Inside the box body 30, a winding rod 3021 and a motor 301 are arranged. 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 10 to drive the rotation of the winding rod 3021, the control of the TV's winding and unwinding is realized. One side edge of the display panel 10 is connected to the winding rod 3021. 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. 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.

[0069] The outer shape of the box body 30 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" - shaped, "T" - shaped, or irregular. The connection of each part in the box body 30 can be carried out by means such as screws, buckles, welding, etc. The winding rod 3021 can use different involute - shaped 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. The end cover of the counterweight rod 40 can be provided with small steps for limiting the wound display panel and covering 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.

[0070] 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 magic tape. For example, installing one or more pairs of magnetic attraction devices can avoid the situation that the lower end of the display panel shakes due to the influence of wind or slight external force.

[0071] 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 received into 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 aesthetics but also improves the convenience of TV transportation, is conducive to the popularization and application of the retractable TV, and greatly expands the application scenarios. When winding, with the winding rod 3021 as the starting end, 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 layer 107 is placed on the outer side of the winding. It is wound layer by layer. Along the outside of the winding rod 3021, in turn, are the display surface of the display panel 10, the reinforcement layer 107, the display surface of the display panel 10, the reinforcement layer 107..., and the outermost layer is the reinforcement layer 107.

[0072] Further, auxiliary segments can also be provided on both sides of the display panel 10. The auxiliary segments are connected to the winding rod 3021 and the counterweight rod 40. 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, facilitating packaging, transportation, and installation.

[0073] Furthermore, the auxiliary segments are also made of rollable materials, which can be the same as the material of the backplane film layer 106. Since the auxiliary segments are not used for display, a reinforcing structure layer 107 can be provided on the auxiliary segments, or the reinforcing structure layer 107 can be omitted.

[0074] By connecting the display panel of the first embodiment to a motor, a reel mechanism, etc. to form a rollable TV, the problem of uneven bending deformation after the TV is unrolled is effectively solved.

[0075] Embodiment Three

[0076] Figure 11 FIG. 13 is a schematic diagram of the TV of Embodiment Three. Among them, FIG. 1-1 is an unfolded state diagram of the TV, FIG. 1-2 is a partial enlarged view of position A in FIG. 1-1, and FIG. 1-3 is a rolled-up state diagram of the TV.

[0077] The TV 50 includes the display panel 10 of the first embodiment, a base 60, a lifting mechanism 601, and an upper crossbeam 602. A reel mechanism 302 is provided on the base 60. The reel mechanism 302 includes a winding rod 3021. The winding rod 3021 is connected to one side edge of the display panel 10, and the other side edge of the display panel 10 is connected to the upper crossbeam 602. One end of the lifting mechanism 601 is connected to the upper crossbeam 602, and the other end is connected to the base 60.

[0078] For further explanation, the outer shape of the base 60 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" - shaped, "T" - shaped, or irregular. The winding rod 3021 is provided thereon and is connected to one side edge of the display panel. The winding rod 3021 is mainly used for winding the display panel. The winding rod 3021 cooperates with the lifting mechanism 601 to control the lifting of the display panel. The other side edge of the display panel is connected to the upper crossbeam 602, and the upper crossbeam 602 provides an upward tensile force for the display panel.

[0079] Furthermore, 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. The involute can change the height according to the actual situation. The upper crossbeam 602 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 602 can be selected from metal materials such as iron and stainless steel. The end cover of the upper crossbeam 602 can be provided with a small step for limiting the wound display panel and blocking the gap. The connection method between the winding rod 3021, the upper crossbeam 602 and the display panel can be any one of bonding, pressing with a strip, snap connection, etc.

[0080] Furthermore, one end of the lifting mechanism 601 is connected to the upper crossbeam 602 to control the upward movement of the upper crossbeam 602, thereby providing an upward acting force for the unfolding of the display panel. The other end is connected to the base 60, so that it is convenient to shrink the display panel into the base.

[0081] Furthermore, 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.

[0082] In addition, the reel mechanism 302 can also include a motor (not shown in the figure) that matches the winding rod 3021 to provide power for the winding and unwinding of the entire retractable TV. By controlling the motor to drive the movement of the winding rod 3021 and the lifting structure 601, the control of the TV winding and unwinding is realized.

[0083] Here, the display panel is retractable, so it is beneficial for the winding and unwinding of the TV. When needed, it can be unfolded for viewing, and when not needed, it can be wound up.

[0084] In Figure 11 Figs. 1-3, the display panel 10 is wound into a cylindrical shape in the base 60, and the entire display panel is received in the base, greatly reducing the occupied space, 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 beneficial to the popularization and application of the retractable TV and greatly expands the application scenarios. When winding, 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), the reinforcing structure layer is placed on the outer side of the winding, and they are wound layer by layer. Outward along the winding rod, they 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.

[0085] Further, when the TV of this embodiment is installed in a vehicle, the base can be installed on the roof. In this way, when the TV needs to be watched, it can be unfolded downward from the roof, and after being rolled 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 watched, it can be raised from the vehicle floor, also without occupying the interior space of the vehicle.

[0086] Further, auxiliary sections can also be provided on both sides of the display panel and connected to the winding rod and the counterweight bar through the auxiliary sections. In this way, 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, lower the overall weight of the TV, and is beneficial to packaging, transportation, and installation.

[0087] Further, the auxiliary section is also made of a material that can be curled, which can be the same as the material of the backplane film layer. Since the auxiliary section is not used for display, a reinforcement structure layer can be provided on the auxiliary section, or the reinforcement structure layer can not be provided.

[0088] The utility model effectively solves the problem of uneven bending deformation after the retractable TV is unfolded by connecting the display panel of Embodiment 1 to a base, a lifting mechanism, an upper cross beam, etc. to form a retractable TV.

[0089] The above is only the preferred embodiment of the utility model. It should be noted that the above preferred embodiment should not be regarded as a limitation of the utility model. The protection scope of the utility model should be subject to the scope defined by the claims. For those of ordinary skill in the art in this technical field, several improvements and refinements can be made without departing from the spirit and scope of the utility model, and these improvements and refinements should also be regarded as within the protection scope of the utility model.
