Description
Technical Field
[0001] The present invention relates to the technical field of flexible OLED display screens, and particularly to a flexible OLED display screen module based on a conductive film. Background Art
[0002] Flexible OLED display screens have shown broad application prospects in the fields of smartphones, wearable devices, flexible TVs, etc. due to their advantages such as being thin, bendable, having high luminous efficiency, and wide viewing angles.
[0003] For example, an adjustable display screen provided in the patent with publication number CN110728922B is applicable to a display screen surface that can be formed by splicing multiple pieces. It includes multiple display screen units and an angle adjustment device. The angle adjustment device is located between the display screen units and is used to adjust the angle between the display screen units, so that the adjustable display screen has a curvature. The present invention also discloses a splicing type display device including the above adjustable display screen and its curvature adjustment method. The adjustable display screen, splicing type display device and curvature adjustment method provided by the present invention pre-split the minimum functional unit adjustable display screen into multiple display screen units, and connect them through an angle adjustment device. During use, only splicing parts are needed to splice the adjustable display screens into an overall display screen surface. When it is necessary to switch between a flat surface and a curved surface and adjust the curved surface angle, there is no need to reinstall and replace the splicing parts. Directly adjusting the angle adjustment device can achieve this, which is lower in cost and faster and more convenient to operate;
[0004] A splicing connection structure of a display screen and a flexible LED display screen provided in the patent with publication number CN113847312B includes a splicing device and a display screen. The display screen is magnetically connected to the splicing device. The splicing device includes a frame: It further includes: a first splicing component and a second splicing component installed on the lower surface of the frame. There are two groups of the first splicing component and the second splicing component, and the two groups of the first splicing component and the second splicing component are symmetrically arranged. The first splicing component includes a first mounting plate, and the first mounting plate is fixedly connected to the lower surface of one side of the frame. In the present invention, by connecting the second splicing component with an arc-shaped tooth block and driving a self-locking servo motor, the arc-shaped tooth block meshes with a mating gear, so that the arc-shaped tooth block deflects, realizing an included angle between two display screens and forming a curved screen.
[0005] However, when the above technologies are actually used, the flexible OLED display screen is directly installed on a rigid bracket with a preset curvature. Essentially, it is "the bracket bears the bending and the screen fits passively", which will cause the bending form of the spliced flexible OLED display screen to be rigidly restricted and unable to adapt to dynamic curvature adjustment. Summary of the Invention
[0006] The object of the present invention is to provide a flexible OLED display module based on a conductive film, so as to solve the problem that the bending form of the spliced flexible OLED display is rigidly restricted and cannot adapt to the dynamic adjustment of the curvature.
[0007] To achieve the above object, the present invention provides the following technical solution: A flexible OLED display module based on a conductive film, comprising:

The curvature adjustment rod is an arc-shaped structure, so that the movement of the curvature adjustment rod changes the relative position between the mounting frame plate and the core support rod, and generates bending on the elastic row skeleton and the connecting rod;
[0009] A display component using magnetic splicing, the display component includes a flexible OLED display screen. One end of the flexible OLED display screen is fixedly connected with a flexible pad. The two ends of the flexible pad are respectively fixedly embedded with a first magnetic plate and a second magnetic plate.

One end of the second magnetic plate corresponding to the position of the second pressing piece is provided with a second moving groove, and the second pressing piece is rotatably connected to the inner wall of the second moving groove through a pin shaft. The flexible OLED display screen includes a flexible display screen composed of multiple layers of flexible transparent conductive films arranged in an overlapping splicing manner.
[0012] Preferably, a third moving groove is formed in the side wall of the flexible pad corresponding to the position of the extrusion column, so that the extrusion column is closely attached to the first magnetic plate and the second magnetic plate.
[0013] Preferably, one end of the second extrusion sheet corresponding to the position of the first extrusion sheet is of a frame structure, and one ends of the opposite surfaces of the first extrusion sheet and the second extrusion sheet are respectively of a concave-convex structure, so as to guide the fitting of the second extrusion sheet and the first extrusion sheet.
[0014] Preferably, a first clamping post and a second clamping post are respectively fixedly connected to the middle part of the flexible pad. The first clamping post is clamped on the surface of the fixed rod, and the second clamping post is clamped on the surface of the connecting rod, so that the fixed rod cooperates with the first clamping post and the second clamping post cooperates with the connecting rod to support the display component.
[0015] Preferably, a curvature adjusting component for adjusting the curvature of the display component is further included. The curvature adjusting component includes an offset post fixedly connected to the middle of the curvature adjusting rod. A first driving frame is arranged on the surface of the offset post. An offset groove is formed in the middle of the first driving frame corresponding to the position of the offset post. The offset groove includes two communicating holes, and the inner diameter of the holes is adapted to the diameter of the offset post, so that the offset post moves in the two holes of the offset groove.
[0016] Preferably, the number of the curvature adjusting rods is two. The two first driving frames are arranged up and down along the direction of the core support rod. One ends of the opposite surfaces of the two first driving frames are fixedly connected with a guiding frame. A second driving frame is fixedly connected to the middle of the guiding frame. A connecting pipe is fixedly embedded in the inner wall of the second driving frame. One end of the connecting pipe far away from the second driving frame is fixedly connected with a guiding plate.

One end of the driving post far away from the guiding plate is rotatably connected with a driving handle through a bearing, and the driving handle is threadedly connected to the surface of the connecting pipe.
[0017] Preferably, a guiding groove is formed in the middle of the offset post. The first driving frame, the guiding frame and the second driving frame are all in an I-shaped structure, and the first driving frame, the guiding frame, the second driving frame and the connecting pipe are respectively movably connected to the inner wall of the guiding groove to guide the movement of the first driving frame, the guiding frame, the second driving frame and the connecting pipe.

Driving grooves are formed in the surfaces of the driving posts corresponding to the fixed notches. Brake pads are fixedly connected to the surfaces of the second driving frame corresponding to the fixed notches. Elastic blocks are fixedly connected to the inner walls of the brake pads corresponding to the driving grooves. The inner wall of the guiding groove and the surface of the brake pad are both rough. When the driving post drives the driving groove to rotate, the driving groove drives the elastic block to squeeze the brake pad and make the brake pad closely fit on the inner wall of the guiding groove, so as to limit the relative movement between the connecting pipe and the core support rod. One end of the driving post far away from the guiding plate is fixedly connected with a rotating knob, and the rotating knob movably penetrates and extends to the outside of the driving handle.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] 1. When the elastic support assembly drives the display assembly to bend outwards in the present invention, the angle of the arc structure between the first magnetic plate and the second magnetic plate has a tendency to shrink. However, under the action of the second pressing piece and the first pressing piece abutting against each other, and cooperating with the pressing post to clamp the end parts of the connecting positions of the first magnetic plate and the second magnetic plate, no gap will appear between the two display assemblies. When bending inwards, relying on the magnetism of the first magnetic plate and the second magnetic plate themselves, no gap will be generated between the two display assemblies either. That is, no matter bending inwards or outwards, no gap will be generated at the connecting position between the display assemblies, thus meeting the purpose of being adaptable to dynamic curvature adjustment.
[0020] 2. The present invention also rotates the rotating knob, and the rotating knob drives the driving post and the driving groove to rotate. When the driving groove rotates, the driving groove drives the two elastic blocks to squeeze towards both ends, so that the elastic blocks squeeze the brake pads through the fixed notches on the inner wall of the guiding groove. Since the inner wall of the guiding groove and the surface of the brake pad are both rough, when the brake pad is closely attached to the guiding groove, the second driving frame does not move relative to the guiding groove, that is, the position of the second driving frame is fixed, and the curvature of the display assembly is fixed, thus achieving the purpose of fixing the curvature of the display assembly.

[0043] A display component using magnetic splicing, the display component includes a flexible OLED display screen 201. One end of the flexible OLED display screen 201 is fixedly installed with a flexible pad 202. The first magnetic plate 203 and the second magnetic plate 204 are fixedly embedded at both ends of the flexible pad 202 respectively. A first extrusion piece 206 is rotatably arranged in the middle of the first magnetic plate 203, and a second extrusion piece 208 is rotatably arranged in the middle of the second magnetic plate 204.

When the first magnetic plate 203 and the second magnetic plate 204 are magnetically attracted to each other, the second extrusion piece 208 will be driven to squeeze the first extrusion piece 206 and drive the extrusion columns 209 to clamp the magnetic attraction positions of the first magnetic plate 203 and the second magnetic plate 204. The second magnetic plate 204 and the first magnetic plate 203 are arc-shaped structures. One end of the first magnetic plate 203 corresponding to the position of the first extrusion piece 206 is provided with a first movable groove 205, and the first extrusion piece 206 is rotatably connected to the inner wall of the first movable groove 205 through a pin shaft. One end of the second magnetic plate 204 corresponding to the position of the second extrusion piece 208 is provided with a second movable groove 207, and the second extrusion piece 208 is rotatably connected to the inner wall of the second movable groove 207 through a pin shaft. The flexible OLED display screen 201 includes a flexible display screen composed of multiple layers of flexible transparent conductive films arranged in an overlapping splicing manner. A third movable groove 210 is provided on the side wall of the flexible pad 202 corresponding to the position of the extrusion column 209, so that the extrusion column 209 is closely attached to the first magnetic plate 203 and the second magnetic plate 204. One end of the second extrusion piece 208 corresponding to the position of the first extrusion piece 206 is a frame-shaped structure, and one end of the opposite surfaces of the first extrusion piece 206 and the second extrusion piece 208 are respectively concave-convex structures, so as to guide the fitting of the second extrusion piece 208 and the first extrusion piece 206;
[0044] When the above structure is in use, by first aligning the first magnetic plate 203 and the second magnetic plate 204, making the first magnetic plate 203 and the second magnetic plate 204 closely fit, and making the first extrusion piece 206 and the second extrusion piece 208 closely fit, so that the first extrusion piece 206 and the second extrusion piece 208 squeeze each other and drive the extrusion columns 209 to clamp the end parts of the connecting positions of the first magnetic plate 203 and the second magnetic plate 204, so as to avoid the loosening of the connecting positions when adjusting the curvature between multiple display components, that is, no matter bending inward or outward, there will be no gap at the connecting positions between the display components, which affects the use of the viewer.
[0045] The middle part of the flexible pad 202 is fixedly installed with a first clamping post 211 and a second clamping post 212 respectively. The first clamping post 211 is clamped on the surface of the fixed rod 102, and the second clamping post 212 is clamped on the surface of the connecting rod 104, so that the fixed rod 102 cooperates with the first clamping post 211 and the second clamping post 212 cooperates with the connecting rod 104 to support the display component;
[0046] When the above structure is in use, the first clamping post 211 in the middle part of the display component is clamped on the surface of the fixed rod 102, and at the same time, the position of the connecting rod 104 is adjusted so that the second clamping post 212 is clamped on the surface of the connecting rod 104. At this time, the display component relies on the cooperation of the first clamping post 211 and the fixed rod 102 and the cooperation of the second clamping post 212 and the connecting rod 104 to be placed on the surface of the elastic support component, and the elastic support component completes the flexible support of the display component.
[0047] It further includes a curvature adjustment component for adjusting the curvature of the display component. The curvature adjustment component includes an offset post 301 fixedly installed in the middle of the curvature adjustment rod 105. A first driving frame 302 is provided on the surface of the offset post 301. An offset groove 303 is opened in the middle of the first driving frame 302 corresponding to the position of the offset post 301. The offset groove 303 includes two connected holes, and the inner diameter of the holes is adapted to the diameter of the offset post 301, so that the offset post 301 can move in the two holes of the offset groove 303. The number of curvature adjustment rods 105 is two. The two first driving frames 302 are arranged up and down along the direction of the core support rod 101. One end of the opposite surfaces of the two first driving frames 302 is fixedly installed with a guide frame 305. A second driving frame 306 is fixedly installed in the middle of the guide frame 305. A connecting pipe 307 is fixedly embedded in the inner wall of the second driving frame 306. One end of the connecting pipe 307 away from the second driving frame 306 is fixedly installed with a guide plate 308. Connecting frames 304 are fixedly installed at both ends of the surface of the offset post 301. An activity frame 309 is fixedly installed in the middle of the connecting frame 304 corresponding to the position of the connecting pipe 307. The connecting pipe 307 movably penetrates and extends to both ends of the activity frame 309. A driving post 311 is rotatably connected to the inner wall of the connecting pipe 307. One end of the driving post 311 is rotatably connected with a connecting block 310 through a bearing, and the connecting block 310 is fixedly installed on the inner wall of the activity frame 309. A fourth activity groove 312 is opened on the side wall of the connecting pipe 307 corresponding to the position of the connecting block 310, so that the connecting block 310 can move back and forth on the inner wall of the fourth activity groove 312. One end of the driving post 311 away from the guide plate 308 is rotatably connected with a driving handle 317 through a bearing, and the driving handle 317 is threadedly connected to the surface of the connecting pipe 307;
[0048] When the above structure is in use, the driving handle 317 is rotated and the driving handle 317 is threadedly connected to the connecting tube 307, thereby driving the driving column 311 to move on the inner wall of the connecting tube 307, so that the driving column 311 drives the movable frame 309 to move forward and backward through the connecting block 310, which makes the movable frame 309 cooperate with the connecting frame 304 to drive the offset column 301 to move in the two holes of the offset groove 303;
[0049] When the offset column 301 moves to the hole where the offset slot 303 is located at the rear, that is, the curvature adjustment rod 105 rotates backward in advance, at this time, the curvature adjustment rod 105 is located at the end of the circle center facing the elastic support component, and the second driving frame 306 moves downward, which causes the curvature adjustment rod 105 to drive the mounting frame plate 106 to move toward one end of the elastic support component, so that the multiple display components are bent in a direction away from one end of the flexible OLED display screen 201;
[0050] When the offset column 301 moves to the hole in front of the offset slot 303, that is, the curvature adjustment rod 105 rotates forward in advance, at this time, the curvature adjustment rod 105 is located at the end of the circle with the center facing the display component position, and the downward movement of the second drive frame 306 will cause the curvature adjustment rod 105 to drive the mounting frame plate 106 to move toward one end of the display component, thereby causing multiple display components to bend in the direction close to one end of the flexible OLED display screen 201.
[0051] A guide groove 319 is provided in the middle of the offset column 301. The first drive frame 302, the guide frame 305, and the second drive frame 306 are all I-shaped structures, and the first drive frame 302, the guide frame 305, the second drive frame 306 and the connecting pipe 307 are movably connected to the inner wall of the guide groove 319, so as to guide the movement of the first drive frame 302, the guide frame 305, the second drive frame 306 and the connecting pipe 307. The side walls of the second drive frame 306 and the connecting pipe 307 are respectively provided with fixed notches 314. A driving groove 313 is provided on the surface of the drive column 311 corresponding to the fixed notch 314. The second drive frame 306 has a fixed notch 314 corresponding to the fixed notch 314. The surface of the position is fixedly installed with a brake pad 316, and the inner wall of the brake pad 316 corresponding to the driving groove 313 is fixedly installed with an elastic block 315, and the inner wall of the guide groove 319 and the surface of the brake pad 316 are both roughened, so that when the driving column 311 drives the driving groove 313 to rotate, the driving groove 313 drives the elastic block 315 to squeeze the brake pad 316 and make the brake pad 316 fit tightly against the inner wall of the guide groove 319, so as to limit the relative movement between the connecting pipe 307 and the core support rod 101, and a rotating knob 318 is fixedly installed at one end of the driving column 311 away from the guide plate 308, and the rotating knob 318 movably penetrates and extends to the outside of the driving handle 317;
[0052] When the above structure is in use, by rotating the rotary knob 318, the rotary knob 318 drives the driving column 311 and the driving groove 313 to rotate. When the driving groove 313 rotates, the driving groove 313 drives the two elastic blocks 315 to squeeze towards both ends, so that the elastic blocks 315 squeeze the brake pads 316 against the inner wall of the guiding groove 319 through the fixing notch 314. Since the inner wall of the guiding groove 319 and the surface of the brake pads 316 are both roughened, when the brake pads 316 are in close contact with the guiding groove 319, the second driving frame 306 does not move relative to the guiding groove 319, that is, the position of the second driving frame 306 is fixed, which means the curvature of the display component is fixed, thus achieving the purpose of fixing the curvature of the display component.
[0053] Working principle: When in use, in the invention, when splicing the display components, first align the flexible pads 202, and align the first magnetic plate 203 with the second magnetic plate 204. Under the magnetic action of the first magnetic plate 203 and the second magnetic plate 204, the first magnetic plate 203 and the second magnetic plate 204 are in close contact. A metal contact is provided between the two flexible pads 202 to achieve power connection. After the first magnetic plate 203 and the second magnetic plate 204 are in close contact, the first pressing piece 206 and the second pressing piece 208 are in close contact, so that the first pressing piece 206 and the second pressing piece 208 squeeze each other and drive the pressing column 209 to clamp the ends of the connecting positions of the first magnetic plate 203 and the second magnetic plate 204, so as to avoid loosening of the connecting positions when adjusting the curvature between multiple display components. That is, when bending outwards, the angles of the arc structures between the first magnetic plate 203 and the first magnetic plate 203, and between the first magnetic plate 203 and the second magnetic plate 204 tend to decrease. However, under the action of the second pressing piece 208 and the first pressing piece 206 being in contact with each other, and in cooperation with the pressing column 209 clamping the ends of the connecting positions of the first magnetic plate 203 and the second magnetic plate 204, no gap will appear between the two display components. When bending inwards, relying on the magnetic properties of the first magnetic plate 203 and the second magnetic plate 204 themselves, no gap will be generated between the two display components either. That is, whether bending inwards or outwards, no gap will be generated at the connecting positions of the display components, which will affect the use of the viewer.
[0054] After the display components are assembled, the display components at both ends are assembled with the mounting frame plate 106 by magnetic attraction through the first magnetic plate 203. At the same time, the first clamping post 211 in the display component in the middle is clamped on the surface of the fixing rod 102. At the same time, the position of the connecting rod 104 is adjusted so that the second clamping post 212 is clamped on the surface of the connecting rod 104. At this time, the display component is placed on the surface of the elastic support component by the cooperation of the first clamping post 211 and the fixing rod 102 and the cooperation of the second clamping post 212 and the connecting rod 104, and the elastic support component completes the flexible support of the display component. The first clamping post 211 and the second clamping post 212 are respectively located in the flexible pad 202. Therefore, the first clamping post 211 and the second clamping post 212 have the function of slightly moving relative to the flexible OLED display screen 201 to adapt to the change in the curvature of the display component caused by the change in the shape of the elastic support component. The fixing rod 102 is located at the central position of the elastic support component and the display component, and the fixing rod 102 is fixedly installed with the core support rod 101. This makes it so that when the curvature changes, the change occurs at the central position where the fixing rod 102 is located;
[0055] When it is necessary to change the curvature of the display component, at this time, rotate the driving handle 317 and thread the driving handle 317 with the connecting pipe 307, thereby driving the driving column 311 to move on the inner wall of the connecting pipe 307. And when the driving column 311 moves on the inner wall of the connecting pipe 307, it will cause the driving column 311 to drive the movable frame 309 to move back and forth through the connecting block 310;
[0056] When the movable frame 309 is driven by the driving column 311 and the connecting block 310 to move backward, this will cause the movable frame 309 to cooperate with the connecting frame 304 to drive the offset column 301 to move backward in advance, that is, the offset column 301 moves into the hole at the rear of the offset groove 303, so that the curvature adjustment rod 105 rotates backward in advance, that is, at this time, the curvature adjustment rod 105 is at the end where the center of the circle faces the elastic support component. At this time, by driving the second driving frame 306 to move downward along the direction of the guiding groove 319 through the driving handle 317, it will cause the curvature adjustment rod 105 to drive the mounting frame plate 106 to move toward one end of the elastic support component, and the mounting frame plate 106 will drive both ends of the elastic row skeleton 103 and the connecting rod 104 to bend toward one end of the elastic support component. That is, due to the change in the curvature of the mounting frame plate 106 and the connecting rod 104, multiple display components will bend in the direction away from one end of the flexible OLED display screen 201;
[0057] When the movable frame 309 is driven by the driving column 311 in cooperation with the connecting block 310 to move forward, this will cause the movable frame 309 to drive the offset column 301 to move forward in advance in cooperation with the connecting frame 304, that is, the offset column 301 moves into the hole in the front of the offset groove 303, so that the curvature adjustment rod 105 rotates forward in advance. That is, at this time, the curvature adjustment rod 105 is located at one end with the center facing the display component. At this time, driving the second driving frame 306 to move downward along the direction of the guide groove 319 by the driving handle 317 will cause the curvature adjustment rod 105 to drive the mounting frame plate 106 to move towards one end of the display component, and cause the mounting frame plate 106 to drive both ends of the elastic row skeleton 103 and the connecting rod 104 to bend towards one end of the display component. That is, due to the curvature change of the mounting frame plate 106 and the connecting rod 104, multiple display components will bend towards the direction close to one end of the flexible OLED display screen 201;
[0058] That is, by changing the position of the offset column 301 in the two holes of the offset groove 303, the purpose of changing the bending direction can be achieved;
[0059] When the curvature adjustment is completed, rotate the rotation knob 318, and make the rotation knob 318 drive the driving column 311 and the driving groove 313 to rotate. And when the driving groove 313 rotates, it will cause the driving groove 313 to squeeze two elastic blocks 315 towards both ends, so that the elastic blocks 315 squeeze the brake pads 316 against the inner wall of the guide groove 319 through the fixed notch 314. Since the inner wall of the guide groove 319 and the surface of the brake pads 316 are both roughened, when the brake pads 316 are in close contact with the guide groove 319, the second driving frame 306 does not move relative to the guide groove 319, that is, the position of the second driving frame 306 is fixed, which means the curvature of the display component is fixed, thus achieving the purpose of fixing the curvature of the display component.
