Description

Technical Field

[0001] The present invention belongs to the field of outdoor TVs, and specifically relates to an outdoor OLED TV set. Background Art

[0002] TV sets are common electrical appliances used to receive and display TV signals for people to watch various programs. With the development of technology, TV sets have evolved from cathode ray tubes to display technologies such as liquid crystal, plasma, and OLED.

[0003] Outdoor TV sets are TV devices designed specifically for outdoor environments. They have some special functional features and technical parameters to adapt to the changeable outdoor environmental conditions; for example, in terms of the waterproof and dustproof level, outdoor TV sets usually have a high-level waterproof and dustproof function; high brightness: outdoor TV sets use high-brightness backlights to ensure clear visibility even in strong light, etc.

[0004] The screen sizes of traditional outdoor TV sets are often fixed and the height cannot be adjusted. However, when using outdoor TV sets, it is necessary to play appropriate pictures according to the user's required scenarios, but it is difficult for traditional outdoor TVs to achieve the above functions.

[0005] Therefore, the present invention provides an outdoor OLED TV set. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An outdoor OLED TV set according to the present invention includes a laying platform. A hydraulic rod for regulating the lifting of the laying platform is arranged below the laying platform. A roll-shaped OLED flexible screen is arranged at the front end of the laying platform. A winding roller capable of horizontal movement is also arranged at the front end of the laying platform. The OLED flexible screen is wound outside the winding roller. The winding roller is arranged vertically. A servo motor two for driving the winding roller to rotate is installed at the top of the winding roller. One end of the OLED flexible screen is fixedly connected with an output main board. Through the setting of the hydraulic rod and the display stand, the OLED flexible screen uses a flexible substrate, allowing itself to be bent. When only a small-sized screen is needed, the winding roller moves horizontally, and at the same time, the second servo motor rotates to unfold the OLED flexible screen outside the winding roller at the front end of the display stand. The output main board controls the display screen of the OLED flexible screen; since the OLED has no backlight layer, each pixel point can be freely lit, so it is possible to only light the unfolded part of the OLED flexible screen, which can reduce energy consumption; when it is necessary to show the screen to more people, start the hydraulic rod to lift the entire display stand upward, and at the same time move the winding roller to make the OLED flexible screen cover the entire display stand, so that a larger screen can be displayed. Through this operation, the TV can be applied to different scenarios and is more flexible and changeable than traditional outdoor TVs; at the same time, when the screen does not need to be displayed, the OLED flexible screen can be wound up outside the winding roller by the drive of the second servo motor and the translation of the winding roller. Because the outdoor environment is prone to encountering bad weather, which may damage the display part of the TV, by winding up to reduce the volume, the influence of the external environment can be greatly reduced.

[0008] Preferably, the display stand is composed of a first split screen platform and a second split screen platform. A first servo motor for controlling the rotation of the second split screen platform is installed at the rear end of the first split screen platform. The output end of the first servo motor is fixedly connected with a vertical driving arm, and the driving arm is fixedly connected with the second split screen platform. In order to ensure comfortable viewing, when playing a small-sized screen, the first servo motor drives the driving arm to rotate to control the second split screen platform to rotate and fold, and only the first split screen platform is displayed in the front. When a large screen is needed for viewing, the second split screen platform is rotated to the front, thus ensuring the viewing comfort; it should be noted that the maximum folding angle of the second split screen platform cannot touch the deceleration motor.

[0009] Preferably, a horizontally arranged deceleration motor is installed at the top of the hydraulic rod. The output end of the deceleration motor is fixedly connected to the middle of the first split screen platform. An arc-shaped support frame is fixedly connected between the hydraulic rod and the deceleration motor. When the first split screen platform shows a small picture, it can only play in a vertical screen or reduce the display of the horizontal screen picture. In order to enable the first split screen platform to also play in a vertical screen, the deceleration motor can be used to control the first split screen platform to rotate clockwise by 90 degrees, so that the unfolded part of the OLED flexible screen can also normally display the picture in a vertical screen, further improving the picture display effect and ensuring viewing comfort.

[0010] Preferably, clamping grooves are formed on both the upper and lower sides of the laying table, a driving table is slidably connected in the clamping grooves, an electric telescopic rod is fixedly connected to the top of the driving table, the upper electric telescopic rod is fixedly connected to the second servo motor, and the end of the lower electric telescopic rod is rotatably connected to the end of the winding roller. An electric gear is installed on the outer side of the driving table, and a rack engaged with the electric gear is fixedly connected in the clamping groove. By rotating the electric gear and engaging the electric gear with the rack, the electric telescopic rod is driven to move horizontally. During the horizontal movement, in cooperation with the rotation of the second servo motor, the winding and releasing of the OLED flexible screen are completed. At the same time, the electric telescopic rod needs to expand and contract during the translation process because as the OLED flexible screen unfolds, the thickness outside the winding roller will decrease. To ensure that the OLED flexible screen is laid flat on the outside of the laying table, the electric telescopic rod is required to control the distance between the winding roller and the laying table, ensuring the neat laying and winding process of the OLED flexible screen.

[0011] Preferably, a recovery cover is arranged at one end of the first screen splitting table away from the second screen splitting table. The end of the recovery cover facing the first screen splitting table is open, and the outer side of the recovery cover is fixedly connected to the rear end of the second screen splitting table. The output main board is located in the recovery cover. When the picture does not need to be displayed, the wound OLED flexible screen and the winding roller are translated into the recovery cover, which can effectively reduce the influence of the external environment on the OLED flexible screen.

[0012] Preferably, the front end of the laying table is arranged in a concave shape. The OLED flexible screen is composed of a flexible screen body and a pressing pad. The pressing pad is made of an elastic material. During the unfolding process of the OLED flexible screen, the unfolded OLED flexible screen will be restricted in the front concave of the laying table. At the same time, the setting of the pressing pad enables the back of the OLED flexible screen to closely adhere to the laying table. The pressing pad is appropriately deformed under pressure, so that the back of the OLED flexible screen is uniformly stressed in the vertical state. At the same time, with the cooperation of the horizontal pulling force, the flatness of the front end of the flexible screen body can be ensured, further ensuring the integrity and quality of the picture.

[0013] Preferably, a plurality of magnetic strips are fixedly connected to the front end of the laying table, and the plurality of magnetic strips are arranged at equal intervals from top to bottom. A flexible metal plate is embedded in the pressing pad. After the OLED flexible screen is unfolded, the flexible metal plate inside the pressing pad will be magnetically adsorbed to the magnetic strips. At this time, a large frictional force can be provided to the back of the OLED flexible screen to keep the OLED flexible screen in the unfolded state, rather than relying on the pulling force of the winding roller, so as not to over-pull the OLED flexible screen and cause damage. The flexible metal plate is magnetically adsorbed and will also isolate the magnetic field of the magnetic strips, reducing the influence of the magnetic field on the OLED flexible screen.

[0014] Preferably, an extension frame is fixedly connected to the outer edge of the opening of the first split screen platform, and a surrounding frame is fixedly connected to the rear end of the first split screen platform. The surrounding frame is sleeved on the outside of the reduction motor. The setting of the extension frame enables the winding roller to be translated to the front end of the extension frame, so that the front end of the spreading platform is fully covered with the OLED flexible screen, further improving the viewing effect. The setting of the surrounding frame is to share the weight of the spreading platform on the outer shell of the reduction motor. The outer shell of the reduction motor is cylindrical. The surrounding frame can rotate relative to the outside of the reduction motor, and the output end of the reduction motor does not need to bear the gravity of the spreading platform, reducing the burden on the output end of the reduction motor.

[0015] Preferably, the aspect ratio of the spreading platform is 16:9, and the aspect ratio of the OLED flexible screen after being unfolded on the first split screen platform is 16:9. Traditional movie screens are generally 16:9. When playing a small picture, when the OLED flexible screen is unfolded on the first split screen platform and the first split screen platform rotates 90 degrees, at this time, the aspect ratio of the unfolded part of the OLED flexible screen is 16:9, so that the movie screen can be played normally. When the spreading platform is fully unfolded, the overall spreading platform is also 16:9, and the OLED flexible screen can also play pictures of conventional specifications, thereby improving the practicability of the TV and ensuring the viewing effect at the same time.

[0016] Preferably, an extension bracket is fixedly connected to one end of the second split screen platform, and the connection end between the first split screen platform and the second split screen platform is set to have a smooth transition. When it is necessary to display pictures in two directions, first let the winding roller unfold the OLED flexible screen outward, and then an included angle can be rotated between the first split screen platform and the second split screen platform. During the rotation process, the winding roller translates and releases the OLED flexible screen. Then, the OLED flexible screens at the front ends of the first split screen platform and the second split screen platform display pictures separately, and the effect of displaying pictures in different directions can be achieved, further improving the applicable range of the TV. The smooth transition setting at the front ends of the first split screen platform and the second split screen platform is to prevent damage to the OLED flexible screen.

[0017] The beneficial effects of the present invention are as follows: 1. An outdoor OLED TV set according to the present invention, through the settings of hydraulic rods and a laying table, when only a small-sized screen is required, the winding roller moves horizontally, and at the same time, the second servo motor rotates to unfold the OLED flexible screen outside the winding roller at the front end of the laying table, and the output main board controls the OLED flexible screen to display the picture; since OLED has no backlight layer and each pixel can be freely lit, it is possible to only light the unfolded part of the OLED flexible screen, which can reduce energy consumption; when more people need to watch, the hydraulic rods are activated to lift the entire laying table upward, and at the same time, the winding roller is moved to make the OLED flexible screen cover the entire laying table, so as to display a larger picture. Through such operations, this TV can be applied to different scenarios and is more flexible and changeable compared with traditional outdoor TVs; at the same time, when the picture does not need to be displayed, the OLED flexible screen can be wound outside the winding roller by the drive of the second servo motor and the translation of the winding roller. Because the outdoor environment is prone to bad weather and the display part of the TV set may be damaged, by winding and reducing the volume, the influence of the external environment can be greatly reduced.

[0018] 2. An outdoor OLED TV set according to the present invention, in order to ensure comfortable viewing, when playing a small-sized picture, the first servo motor drives the drive arm to rotate to control the second split screen platform to rotate and fold, and only the first split screen platform is displayed in the front. When a large screen is needed for viewing, the second split screen platform is rotated to the front, thus ensuring the viewing comfort; it should be noted that the maximum folding angle of the second split screen platform cannot touch the deceleration motor.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] As Figures 1 to 7 shown, an outdoor OLED TV set described in an embodiment of the present invention includes a display platform 2. A hydraulic rod 1 for regulating the lifting of the display platform 2 is arranged below the display platform 2. A coiled OLED flexible screen 5 is arranged at the front end of the display platform 2. A horizontally movable winding roller 7 is also arranged at the front end of the display platform 2. The OLED flexible screen 5 is wound outside the winding roller 7. The winding roller 7 is arranged vertically. A servo motor 2 for driving the winding roller 7 to rotate is installed at the top of the winding roller 7. One end of the OLED flexible screen 5 is fixedly connected with an output main board 24; During small-scale activities, only by playing a general-sized picture at a lower place can people participating in the activities observe it normally. If an extra-large picture is used at this time, it is not conducive to the participants to observe the picture; during large-scale activities or promotional activities, due to the large number of participants, the playing picture needs to be raised so that more people can see it. At the same time, the picture also needs to be enlarged to facilitate the viewing of people in the distance; Through the settings of the hydraulic rod 1 and the display platform 2, the OLED flexible screen 5 uses a flexible substrate, allowing itself to be bent. When only a small-sized screen is needed, the winding roller 7 moves horizontally, and at the same time, the second servo motor 20 rotates to unfold the OLED flexible screen 5 outside the winding roller 7 at the front end of the display platform 2. The output main board 24 controls the OLED flexible screen 5 to display the picture. Since OLED has no backlight layer and each pixel can be freely lit, it is possible to only light the unfolded part of the OLED flexible screen 5, which can reduce energy consumption. When more people need to watch, the hydraulic rod 1 is activated to lift the entire display platform 2 upward, and at the same time, the winding roller 7 is moved to make the OLED flexible screen 5 cover the entire display platform 2, enabling a larger picture to be displayed. Through this operation, the TV can be applied to different scenarios and is more flexible and changeable compared to traditional outdoor TVs. At the same time, when the picture does not need to be displayed, the OLED flexible screen 5 can be wound up outside the winding roller 7 through the drive of the second servo motor 20 and the translation of the winding roller 7. Since the outdoor environment is prone to bad weather, which may damage the display part of the TV, the impact of the external environment can be greatly reduced by winding up to reduce the volume.

[0024] The display platform 2 is composed of a first split screen platform 16 and a second split screen platform 17. A first servo motor 10 for controlling the rotation of the second split screen platform 17 is installed at the rear end of the first split screen platform 16. The output end of the first servo motor 10 is fixedly connected to a vertical driving arm 11, and the driving arm 11 is fixedly connected to the second split screen platform 17. During operation, in order to ensure comfortable viewing, when playing a small-sized picture, the first servo motor 10 drives the driving arm 11 to rotate, controlling the second split screen platform 17 to rotate and fold, and only the first split screen platform 16 is displayed in the front. When a large screen is needed for viewing, the second split screen platform 17 is rotated to the front, thus ensuring the viewing comfort.

[0025] A horizontally arranged reduction motor 12 is installed at the top of the hydraulic rod 1. The output end of the reduction motor 12 is fixedly connected to the middle of the first split screen platform 16. An arc-shaped support frame 13 is fixedly connected between the hydraulic rod 1 and the reduction motor 12. During operation, when the first split screen platform 16 shows a small picture, it can only play in a vertical screen or display a reduced horizontal screen picture. In order to enable the first split screen platform 16 to also play in a vertical screen, the reduction motor 12 can be used to control the first split screen platform 16 to rotate clockwise by 90 degrees, so that the unfolded part of the OLED flexible screen 5 can also display the picture in a normal vertical screen, further improving the picture display effect and ensuring viewing comfort. It should be noted that the maximum folding angle of the second split screen platform 17 cannot touch the reduction motor 12.

[0026] Both the upper and lower sides of the laying table 2 are provided with clamping grooves 19, a driving table 18 is slidably connected in the clamping grooves 19, an electric telescopic rod 6 is fixedly connected to the top of the driving table 18, the electric telescopic rod 6 located above is fixedly connected to a second servo motor 20, and the end of the electric telescopic rod 6 located below is rotatably connected to the end of a winding roller 7. An electric gear is installed on the outside of the driving table 18, and a clamping rack meshing with the electric gear is fixedly connected in the clamping groove 19; During operation, the electric gear rotates, and the meshing of the electric gear and the clamping rack drives the electric telescopic rod 6 to move horizontally. During the horizontal movement, in cooperation with the rotation of the second servo motor 20, the winding and releasing of the OLED flexible screen 5 are completed. At the same time, the electric telescopic rod 6 needs to expand and contract during the translation process because as the OLED flexible screen 5 unfolds, the thickness outside the winding roller 7 will decrease. To ensure that the OLED flexible screen 5 is laid flat outside the laying table 2, the electric telescopic rod 6 needs to control the distance between the winding roller 7 and the laying table 2, ensuring the neat winding and unwinding process of the OLED flexible screen 5.

[0027] One end of the first screen splitting table 16 away from the second screen splitting table 17 is provided with a recovery cover 3. One end of the recovery cover 3 facing the first screen splitting table 16 is open, the outside of the recovery cover 3 is fixedly connected to the rear end of the second screen splitting table 17, and the output main board 24 is located in the recovery cover 3; During operation, when the picture does not need to be displayed, the wound OLED flexible screen 5 and the winding roller 7 are translated into the recovery cover 3, which can effectively reduce the influence of the external environment on the OLED flexible screen 5.

[0028] The front end of the laying table 2 is arranged in a concave shape. The OLED flexible screen 5 is composed of a flexible screen body 21 and a pressing pad 22, and the pressing pad 22 is made of an elastic material; During operation, during the unfolding process of the OLED flexible screen 5, the unfolded OLED flexible screen 5 will be restricted in the concave of the front end of the laying table 2. At the same time, the setting of the pressing pad 22 allows the back surface of the OLED flexible screen 5 to closely adhere to the laying table 2. The pressing pad 22 is appropriately deformed under extrusion, so that the back surface of the OLED flexible screen 5 is uniformly stressed in the vertical state. At the same time, with the cooperation of the horizontal pulling force, the flatness of the front end of the flexible screen body 21 can be ensured, further ensuring the integrity and quality of the picture.

[0029] A plurality of magnetic strips 8 are fixedly connected to the front end of the laying table 2, and the plurality of magnetic strips 8 are arranged at equal intervals from top to bottom. A flexible metal plate 23 is embedded in the pressing pad 22; During operation, after the OLED flexible screen 5 is laid out, the flexible metal plate 23 inside the extrusion pad 22 will be magnetically adsorbed to the magnetic strip 8. At this time, a large frictional force can be provided to the back of the OLED flexible screen 5 to keep the OLED flexible screen 5 in the unfolded state, rather than relying on the pulling force of the winding roller 7, so as not to over-pull the OLED flexible screen 5 and cause damage. The flexible metal plate 23 is magnetically adsorbed and will also isolate the magnetic field of the magnetic strip 8, reducing the influence of the magnetic field on the OLED flexible screen 5.

[0030] An extension frame 4 is fixedly connected to the outer edge of the opening of the first split screen table 16, and a surrounding frame 15 is fixedly connected to the rear end of the first split screen table 16. The surrounding frame 15 is sleeved on the outside of the reduction motor 12; During operation, due to the setting of the extension frame 4, the winding roller 7 can be translated to the front end of the extension frame 4, so that the front end of the laying table 2 is fully covered with the OLED flexible screen 5, further improving the viewing effect. The setting of the surrounding frame 15 is to share the weight of the laying table 2 on the outer shell of the reduction motor 12. The outer shell of the reduction motor 12 is cylindrical. The surrounding frame 15 is provided to be rotatable relative to the outside of the reduction motor 12, and the output end of the reduction motor 12 does not need to bear the gravity of the laying table 2, reducing the burden on the output end of the reduction motor 12.

[0031] The aspect ratio of the laying table 2 is 16:9, and the aspect ratio of the OLED flexible screen 5 after being unfolded on the first split screen table 16 is 16:9; During operation, the traditional movie picture is generally 16:9. When playing a small picture, after the OLED flexible screen 5 is unfolded on the first split screen table 16, the first split screen table 16 rotates 90 degrees. At this time, the aspect ratio of the unfolded part of the OLED flexible screen 5 is 16:9, so that the movie picture can be played normally. After the laying table 2 is fully unfolded, the overall laying table 2 is also 16:9, and the OLED flexible screen 5 can also play pictures of conventional specifications, thus improving the practicality of the TV and ensuring the viewing effect at the same time.

[0032] One end of the second split screen table 17 is fixedly connected with an extension bracket 9, and the connection end of the first split screen table 16 and the second split screen table 17 is set to have a smooth transition; During operation, when it is necessary to display pictures in two directions, first let the winding roller 7 unfold the OLED flexible screen 5 outwards, and then an included angle can be rotated between the first split screen table 16 and the second split screen table 17. During the rotation process, the winding roller 7 translates and releases the OLED flexible screen 5. Then, the OLED flexible screens 5 at the front ends of the first split screen table 16 and the second split screen table 17 display pictures separately, and the effect of displaying pictures in different directions can be achieved, further improving the applicable range of the TV. The smooth transition setting at the front ends of the first split screen table 16 and the second split screen table 17 is to prevent damage to the OLED flexible screen 5.

[0033] During operation, through the settings of the hydraulic rod 1 and the display stand 2, the OLED flexible screen 5 uses a flexible substrate material, enabling itself to bend. When only a small-sized screen is required, the winding roller 7 moves horizontally, and at the same time, the second servo motor 20 rotates to unfurl the OLED flexible screen 5 outside the winding roller 7 at the front end of the display stand 2. The output main board 24 controls the OLED flexible screen 5 to display the picture. Since OLED has no backlight layer and each pixel can be freely lit, only the unfolded part of the OLED flexible screen 5 can be lit, which can reduce energy consumption. When more people need to watch, the hydraulic rod 1 is activated to lift the entire display stand 2 upward, and at the same time, the winding roller 7 is moved to make the OLED flexible screen 5 cover the entire display stand 2, enabling a larger picture to be shown. Through this operation, the TV can be applied to different scenarios and is more flexible and variable compared to traditional outdoor TVs. At the same time, when the picture does not need to be shown, through the drive of the second servo motor 20 and the translation of the winding roller 7, the OLED flexible screen 5 can be wound outside the winding roller 7. Since the outdoor environment is prone to bad weather, which may damage the display part of the TV, the volume can be greatly reduced by winding, thus significantly reducing the impact of the external environment. To ensure comfortable viewing, when playing a small-sized picture, the first servo motor 10 drives the drive arm 11 to rotate, controlling the second splitter platform 17 to rotate and fold, and only the first splitter platform 16 is displayed in the front. When a large screen is needed for viewing, the second splitter platform 17 is then rotated to the front, thus ensuring the viewing comfort. It should be noted that the maximum folding angle of the second splitter platform 17 should not touch the reduction motor 12. When the first splitter platform 16 shows a small picture, it can only play in a vertical screen or display a reduced horizontal screen. To enable the first splitter platform 16 to also play in a vertical screen, the reduction motor 12 can be used to control the first splitter platform 16 to rotate clockwise by 90 degrees, so that the unfolded part of the OLED flexible screen 5 can also normally display the picture in a vertical screen, further improving the picture display effect and ensuring viewing comfort. Through the rotation of the electric gear and the meshing of the electric gear with the rack, the electric telescopic rod 6 is driven to move horizontally. During the horizontal movement, in cooperation with the rotation of the second servo motor 20, the winding and release of the OLED flexible screen 5 are completed. At the same time, the electric telescopic rod 6 needs to extend and retract during the translation process. Since the thickness outside the winding roller 7 decreases as the OLED flexible screen 5 unfolds, to ensure that the OLED flexible screen 5 is laid flat outside the display stand 2, the electric telescopic rod 6 needs to control the distance between the winding roller 7 and the display stand 2, ensuring the neat unfolding and winding process of the OLED flexible screen 5. When the picture does not need to be shown, the wound OLED flexible screen 5 and the winding roller 7 are translated into the recovery cover 3, which can effectively reduce the impact of the external environment on the OLED flexible screen 5. During the unfolding process of the OLED flexible screen 5, the unfolded OLED flexible screen 5 will be restricted within the front concave of the laying table 2. At the same time, with the setting of the extrusion pad 22, the back surface of the OLED flexible screen 5 can closely adhere to the laying table 2. The extrusion pad 22 will deform appropriately under extrusion, enabling the back surface of the OLED flexible screen 5 to be evenly stressed in the vertical state. Meanwhile, in cooperation with the horizontal pulling force, the flatness of the front end of the flexible screen body 21 can be ensured, further guaranteeing the integrity and quality of the picture; After the OLED flexible screen 5 is unfolded, the flexible metal plate 23 inside the extrusion pad 22 will be magnetically adsorbed to the magnetic strip 8. At this time, a relatively large frictional force can be provided to the back surface of the OLED flexible screen 5 to maintain the unfolded state of the OLED flexible screen 5, rather than relying on the pulling force of the winding roller 7, so as not to over-pull the OLED flexible screen 5 and cause damage. The flexible metal plate 23 being magnetically adsorbed will also isolate the magnetic field of the magnetic strip 8, reducing the influence of the magnetic field on the OLED flexible screen 5; The setting of the outer extension frame 4 enables the winding roller 7 to be translated to the front end of the outer extension frame 4, covering the front end of the laying table 2 with the OLED flexible screen 5, further improving the viewing effect. The setting of the surrounding frame 15 is to distribute the weight of the laying table 2 on the outer shell of the reduction motor 12. The outer shell of the reduction motor 12 is cylindrical. The surrounding frame 15 can rotate relatively outside the reduction motor 12, and the output end of the reduction motor 12 does not need to bear the gravity of the laying table 2, reducing the burden on the output end of the reduction motor 12; The traditional movie screen is generally 16:9. When playing on a small screen, after the OLED flexible screen 5 is unfolded on the first split screen platform 16, the first split screen platform 16 rotates 90 degrees. At this time, the aspect ratio of the unfolded part of the OLED flexible screen 5 is 16:9, so that the movie screen can be played normally. After the laying table 2 is fully unfolded, the overall laying table 2 is also 16:9, and the OLED flexible screen 5 can also play conventional specification pictures, thus improving the practicality of the TV and ensuring the viewing effect at the same time; When it is necessary to display the picture in two directions, first let the winding roller 7 unfold the OLED flexible screen 5 outward. Then, an included angle can be rotated between the first split screen platform 16 and the second split screen platform 17. During the rotation process, the winding roller 7 translates and releases the OLED flexible screen 5. Then, the OLED flexible screen 5 at the front ends of the first split screen platform 16 and the second split screen platform 17 displays the picture separately, and the effect of displaying the picture in different directions can be achieved, further expanding the applicable range of the TV. The smooth transition at the front ends of the first split screen platform 16 and the second split screen platform 17 is set to avoid damaging the OLED flexible screen 5.
