Its structure includes an electrophoretic chip, a flexible substrate, packaging materials, and connecting lines. The flexible substrate uses flexible materials so that the display panel can adapt to various curved shapes. By controlling the brightness and color changes of the electrophoretic chip and combining the input signal received by the control circuit, the flexible electrophoretic display panel can achieve flexible and innovative display effects. For example, a portable waterproof flexible electrophoretic display panel disclosed in the authorization announcement number CN214202999U includes an electrophoretic panel 1 and an electrophoretic panel 2. The number of electrophoretic panels 1 and 2 is set to be several. Both electrophoretic panel 1 and electrophoretic panel 2 use FPC circuit boards. Glue is dripped on the outer side of electrophoretic panel 1. Connection grooves are provided on the left and right sides of electrophoretic panel 1.

[0019] The main round-shaped sealing ring 2 and the auxiliary round-shaped sealing ring 3 are respectively bonded on the outer walls of both sides of the soft rubber shell 1, and the inner edge of the main round-shaped sealing ring 2 and the outer edge of the auxiliary round-shaped sealing ring 3 overlap each other. The staff takes out more than two pieces of the flexible electrophoretic display panels, and the two soft rubber shells 1 are connected end to end in sequence. At this time, the main round-shaped sealing ring 2 on the outer wall of one of the soft rubber shells 1 and the auxiliary round-shaped sealing ring 3 on the outer wall of the other soft rubber shell 1 are matched and contacted with each other;

[0020] Four first fixing plates 7 are installed on one side of the bottom of the soft rubber shell 1, a semicircular spring plate 8 is installed between two adjacent first fixing plates 7, and lower contacts 9 are installed on both sides of the top of the semicircular spring plate 8, and plug holes 6 for the semicircular spring plates 8 to insert are provided on the outer walls of both sides of the soft rubber shell 1, and the width of the plug hole 6 is equal to the width of the semicircular spring plate 8. Two upper mounting plates 11 are installed on the other side of the bottom of the soft rubber shell 1, and an upper spring plate support structure is installed at the bottom end of the upper mounting plate 11. Two upper contacts 14 electrically connected to the lower contacts 9 are installed at the movable end of the upper spring plate support structure;

[0021] The semicircular spring piece 8 on the outer wall of one flexible electrophoretic display panel is plugged into the plug hole 6 on the outer wall of the other flexible electrophoretic display panel, that is, the semicircular spring piece 8 is plugged into the bottom of the U-shaped spring piece 13, and the upper spring piece support structure makes the U-shaped spring piece 13 move downward, while the semicircular spring piece 8 always moves upward under its own elastic force, so that the lower contact 9 and the upper contact 14 are firmly abutted, so that the electrical connection between the two FPC circuit boards 10 is realized;

[0022] The main circular seal ring 2 and the auxiliary circular seal ring 3 are made of polyimide material. The thickness of the main circular seal ring 2 and the auxiliary circular seal ring 3 is 0.1 cm to 0.2 cm. After the two adjacent soft rubber shells 1 are connected, the main circular seal ring 2 and the auxiliary circular seal ring 3 abut against each other to ensure the sealing performance after the adjacent soft rubber shells 1 are connected, and to prevent external liquid from penetrating into the contact point and the FPC circuit board 10;

[0023] The upper spring sheet support structure includes two second fixing sheets 12 fixed at the bottom end of the upper mounting plate 11, and a U-shaped spring sheet 13 at one end of the second fixing sheet 12 close to the center line of the upper mounting plate 11, the other end of the U-shaped spring sheet 13 is connected to one end of another second fixing sheet 12, the two ends of the U-shaped spring sheet 13 and one end of the two second fixing sheets 12 are integrally formed, the upper contact 14 is fixed on both sides of the bottom end of the U-shaped spring sheet 13, the semicircular spring sheet 8, the U-shaped spring sheet 13, the lower contact 9, and the upper contact 14 are all made of conductive materials, which can provide stable electrical contact, ensure reliable transmission of current, improve the electrical performance of the display panel, and ensure the stability of the display effect;

A convex piece 1301 is integrally formed at one end of the U-shaped spring piece 13 close to the right-angle seat 15. The convex piece 1301 and the columnar protrusion 1501 are slidably fitted. When the U-shaped spring piece 13 moves, the U-shaped spring piece 13 and the end of the second fixing piece 12 are integrally lofted and formed. The lofted molding section is an elastic part, so that the U-shaped spring piece 13 is always facing downward, thereby ensuring that the upper contact 14 and the lower contact 9 are firmly abutted. When the U-shaped spring piece 13 slides up and down, the convex piece 1301 slides on the surface of the columnar protrusion 1501, so that the U-shaped spring piece 13 stably deforms. After the two panels are connected by the semicircular spring piece 8 and the U-shaped spring piece 13, they have the advantages of flexible adaptability and maintainability.

[0025] When one of the display panels needs to be replaced or repaired, only the elastic connection needs to be disconnected without disassembling the entire connection and glue processing structure, which reduces maintenance costs and time. At the same time, the elastic connection structure is also scalable, and the number of display panels can be easily increased or decreased to adapt to different needs and scenarios.

[0026] When the embodiment of the present application is in use, the staff first takes out more than two pieces of the flexible electrophoretic display panels. At this time, the two soft glue shells 1 are connected end to end in sequence. At this time, the main round-shaped sealing ring 2 on the outer wall of one of the soft glue shells 1 and the secondary round-shaped sealing ring 3 on the outer wall of the other soft glue shell 1 are matched and contacted with each other. In this process, the semicircular spring piece 8 on the outer wall of one of the flexible electrophoretic display panels is plugged into the plug-in hole 6 on the outer wall of the other flexible electrophoretic display panel, that is, the semicircular spring piece 8 is plugged into the bottom of the U-shaped spring piece 13, and the upper spring piece support structure makes the U-shaped spring piece 13 move downward, while the first fixing piece 7 and the semicircular spring piece 8 are always upward under the action of their own elastic force, so that the lower contact 9 and the upper contact 14 are firmly abutted to realize the electrical connection between the two FPC circuit boards 10. Compared with the traditional plug-in connection method, the elastic connection structure in the panel can save the plug-in and glue dripping steps. It only needs to align and press the display panel to achieve quick connection, which saves the connection time required for the panel.
