Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic paper frame structures, and particularly relates to an electronic paper frame structure with mild curing. Background Technique
[0002] Electronic paper is an ultra-thin and ultra-light display screen. Its display effect is close to that of ordinary paper, making people feel comfortable when reading. And it can convert and refresh to display new content like a common liquid crystal display. Electronic paper has many advantages such as being convenient for reading, easy to carry, having a large information storage capacity, saving resources, and fast dissemination speed. It is precisely due to these advantages that electronic paper has gradually integrated into people's lives and has broad development prospects.
[0003] However, when most electronic paper frame structures are in use, the border sealing glue used is mostly a thermal curing system, which has relatively high requirements for curing temperature and time. Generally, the required curing temperature > 70 °C and the curing time needs to be 30 - 60 minutes. But with the current electronic ink of manufacturers being more sensitive to temperature, a curing temperature of 60 °C or even lower is required. Such a low curing temperature is difficult to achieve a good curing effect for the thermal curing system. Content of the Utility Model
[0004] The purpose of the utility model is to provide an electronic paper frame structure with mild curing, so as to solve the problem that the electronic paper frame structure is not easy to be cured mildly during processing proposed in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an electronic paper frame structure with mild curing, including a glass bottom plate, a pressing plate, and a driving chip. One end of the glass bottom plate is provided with a pressing plate, and one end of the pressing plate is installed with a driving chip. One side of the pressing plate is provided with an FPC circuit board, and the end of the FPC circuit board far from the pressing plate is connected with an interface. An electronic paper film is arranged between the glass bottom plate and the pressing plate, and a sealant is arranged between the electronic paper film and the glass bottom plate.
[0006] Preferably, a positioning block is arranged on one side of the glass bottom plate close to the electronic paper film, and the shape of the positioning block is set as a "square" shape.
[0007] Preferably, symmetrically distributed reserved slots are opened at both ends of the pressing plate, and micro-screws are threadedly connected inside the reserved slots.
[0008] Preferably, an empty slot is opened on one side of the pressing plate close to the reserved slot, and a limiting rod is arranged inside the empty slot.
[0009] Preferably, a limiting spring is connected between one end of the limiting rod close to the micro-screw and the empty slot, and guide rods are arranged on both sides of the limiting rod close to the micro-screw.
[0010] Preferably, the positioning block has a matching insertion hole on the side near the limiting rod.
[0011] Preferably, the pressure plate has an installation groove at one end near the positioning block.
[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This mildly curing electronic paper frame structure addresses the common issue that most frame sealants used in electronic paper frame structure processing are thermosetting systems, requiring high curing temperatures and times (generally >70℃ and 30-60 minutes), making processing inconvenient. By extending the moisture penetration channel through the sealant between the electronic paper film and the glass substrate, the moisture barrier performance is improved. Furthermore, the planar layered structure effectively extends the moisture penetration channel, extending the lifespan of the electronic paper. Simultaneously, the mixed curing of cationic and free radical components increases the crosslinking density and enhances moisture barrier performance. By screening cationic epoxy curing materials and free radical curing materials, adjusting the appropriate ratio of the two systems, and finally using UV curing, the curing conditions are milder, eliminating the high-temperature heating stage and minimizing damage to the electronic paper display unit. This results in a milder curing effect for the electronic paper frame structure during use. Attached Figure Description

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: an e-paper frame structure with mild curing, including a glass bottom plate 1, a pressing plate 2 and a driving chip 3. One end of the glass bottom plate 1 is provided with a pressing plate 2, and one end of the pressing plate 2 is installed with a driving chip 3. One side of the pressing plate 2 is provided with an FPC circuit board 4. The end of the FPC circuit board 4 away from the pressing plate 2 is connected to an interface 5. An e-paper film 6 is provided between the glass bottom plate 1 and the pressing plate 2. A sealant 7 is provided between the e-paper film 6 and the glass bottom plate 1. A positioning block 8 is provided on the side of the glass bottom plate 1 close to the e-paper film 6. The shape of the positioning block 8 is set as a "square" shape. Symmetrically distributed reserved slots 9 are opened at both ends of the pressing plate 2. A micro screw 10 is threadedly connected inside the reserved slot 9. An empty slot 11 is opened on the side of the pressing plate 2 close to the reserved slot 9. A limiting rod 12 is provided inside the empty slot 11. A limiting tension spring 13 is connected between the end of the limiting rod 12 close to the micro screw 10 and the empty slot 11. Guide rods 14 are provided on both sides of the limiting rod 12 close to the micro screw 10. A matching insertion hole 15 is opened on the side of the positioning block 8 close to the limiting rod 12. An installation slot 16 is opened at the end of the pressing plate 2 close to the positioning block 8.
[0020] During specific implementation,
[0021] Refer to Figures 1-4It is known that by extending the water vapor permeation channel through the sealant 7 between the electronic paper film 6 and the glass substrate 1, the water vapor barrier performance can be improved. Furthermore, the stacked planar layer structure effectively extends the water vapor permeation channel, extending the electronic paper's lifespan. Simultaneously, the cationic / free radical hybrid curing increases the crosslinking density and enhances the water vapor barrier performance. By screening cationic epoxy curing materials and free radical curing materials, adjusting the appropriate ratio of the two systems, and finally using UV curing, the curing conditions are gentler, eliminating the high-temperature heating stage and minimizing damage to the electronic paper display unit. This ensures the electronic paper frame structure has a better curing temperature during use. Additionally, the micro-screws 10 inside the pre-reserved groove 9 can be tightened and then rotated, allowing the micro-screws 1... The screw 10 can be removed from the reserved slot 9, allowing the micro screw 10 to separate from the limiting rod 12. This causes the limiting spring 13 on one side of the limiting rod 12 to lose its restraint, allowing the limiting spring 13 to reset and thus restrict the movement of the connected limiting rod 12. When the limiting rod 12 moves, it can separate from the insertion hole 15 inside the positioning block 8, causing the positioning block 8 to lose its restraint and allowing the pressure plate 2 to be removed. Conversely, the limiting rod 12 can be inserted into the insertion hole 15 inside the positioning block 8, allowing the pressure plate 2 and the glass base plate 1 to be stably locked. This improves the sealing of the internal electronic paper film 6, ensuring that the electronic paper frame structure has both good curing and sealing effects during processing.
[0022] In summary, electronic paper is an ultra-thin and ultra-light display screen. Its display effect is close to that of ordinary paper, providing comfortable reading. Like common LCD displays, it can refresh and display new content. By extending the moisture permeation channel through the sealant 7 between the electronic paper film 6 and the glass substrate 1, the moisture barrier performance is improved. Furthermore, the planar layered structure effectively extends the moisture permeation channel, extending the lifespan of the electronic paper. Simultaneously, the cationic / free radical hybrid curing increases the cross-linking density and enhances the moisture barrier performance. By screening cationic epoxy curing materials and free radical curing materials, adjusting the appropriate ratio of the two systems, and finally using UV curing, the curing conditions are gentler, eliminating the high-temperature heating stage and minimizing damage to the electronic paper display unit. This results in a better curing temperature and gentler curing effect for the electronic paper frame structure during use. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
