[0002] Electronic ink display (EI) is a display technology that uses electronic ink as the display medium. The characteristic of this type of display is that the displayed content is not in a bright state, that is, it does not emit light, but relies on reflecting ambient light to display text or images. It is similar to the display effect of paper and has advantages such as power saving, high contrast and suitability for reading. EI displays are commonly used in e-book readers, information displays and other low-power display applications.
[0003] Traditional technologies lack a tight-fitting design to fill gaps in terms of sealing, allowing dust to easily enter from the connection between the display panel and the frame, damaging internal precision components. They also fail to effectively block dust while dissipating heat, leading to dust accumulation inside the device and affecting performance. Furthermore, the interfaces cannot be closed promptly after use to prevent dust from entering. To address these issues, we have proposed a dustproof electronic ink display panel.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a dustproof electronic ink display panel, which has the following beneficial effects:
[0015] 1. This dustproof e-ink display board features a sealing strip on its outer side that tightly fills the gap between the display board and the dustproof frame, effectively preventing dust from entering at the connection point and providing the first line of dust protection. The dustproof cover and dustproof frame are secured with positioning posts and slots and bolted together, ensuring a tight connection and further preventing dust intrusion from the outside. This significantly reduces the risk of dust damage to the precision components inside the display board, extending the equipment's lifespan. The four sets of symmetrical annular heat dissipation holes on the dustproof cover meet the heat dissipation requirements of the e-ink display board during operation. To prevent overheating from affecting display quality and lifespan, each annular heat dissipation hole is equipped with a dust filter, which effectively prevents dust from entering the display panel through the heat dissipation holes. This ensures heat dissipation while maintaining a clean internal environment. The adjustable parts and interface dustproof plates at the bottom of the dustproof frame are cleverly designed. When the interface needs to be used, rotating the torsion cap at the bottom of the adjustable part causes the interface dustproof plate to slide open the interface hole through the meshing of gears and racks. After use, rotating in the opposite direction closes the interface, effectively preventing dust from entering through the interface and providing comprehensive protection for the display panel's dustproof performance.
[0016] 2. This dustproof e-ink display panel features a touch panel on the front side of the dustproof frame that fits snugly against the front display screen. When the user touches the screen, the touch panel quickly converts the touch signal into an electrical signal and transmits it to the e-ink display panel, enabling intuitive and convenient human-computer interaction. This allows users to easily operate the displayed content, enhancing the user experience. The coordination between the adjustment mechanism and the interface dustproof plate makes opening and closing the interface simple and convenient. Simply rotating the twist cap controls the opening and closing state of the interface, meeting the user's interface usage needs in different scenarios. At the same time, it ensures the sealing and dustproof performance of the device when the interface is not in use, thus balancing the dual requirements of functionality and protection.

[0048] Working Principle: The electronic ink display panel 4 is the core component. Its operation is based on electronic ink technology, which consists of numerous tiny charged pigment particles. When an electric field is applied, these particles move within the capsule, with different colored particles moving to different positions, thus displaying different colors and patterns to achieve the display of text and images. To protect the electronic ink display panel 4, a sealing strip 3 is fitted onto its outer side. The rectangular sealing strip 3 is tightly engaged with the electronic ink display panel 4, and then both are installed together inside the dustproof frame 2. The sealing strip 3 effectively fills gaps, preventing dust from entering from the connection between the electronic ink display panel 4 and the dustproof frame 2, providing initial dust protection. A touch panel 1 is located inside the front end of the dustproof frame 2, closely fitting the front display screen of the electronic ink display panel 4. The touch panel 1 can sense touch operations. When a user touches it, the touch panel 1 converts the touch signal into an electrical signal and transmits it to the electronic ink display panel 4, thereby enabling human-computer interaction and allowing the user to operate the displayed content. The dustproof cover 6 further enhances the dustproof effect; its front end corresponds to the back of the dustproof frame 2 for insertion and connection. The positioning post 16 is secured with the positioning groove and then fixed with bolts, ensuring a stable connection. The dust cover 6 has four sets of centrally symmetrical annular heat dissipation holes 15 for heat dissipation during operation of the electronic ink display panel 4, preventing overheating from affecting the display effect and lifespan. Simultaneously, a dust filter 5 is bolted to the front of the dust cover 6, with each filter corresponding to one of the annular heat dissipation holes 15, preventing dust from entering the display panel through the holes. Inside the bottom of the dust cover frame 2, an adjustment component 7 and an interface dust cover 8 are installed. When using the interface, rotate the torsion cap 14 at the bottom of the adjusting component 7. The gear 13 on the adjusting component 7 will rotate accordingly. Since the gear 13 meshes with the rack 11 at the left end of the interface dustproof plate 8, the rotation of the gear 13 will cause the interface dustproof plate 8 to slide in the movable groove 10, thereby opening the interface hole 9. After use, rotate the torsion cap 14 in the opposite direction, and the interface dustproof plate 8 will close the interface hole 9 to prevent dust from entering from the interface. When the gear 13 rotates, the auxiliary rings 12 at both ends of the adjusting component 7 will rub against the sides of the rack 11 to assist in stabilizing the rotation.
