Optimizing the performance of E-Ink displays in relatively harsh environments requires careful consideration of cover design and integration. The cover acts as an important protective barrier to prevent scratches and impacts while enhancing optical clarity and supporting touch functionality.
At Dalian Jiaxian, we offer a range of cover substrates suitable for upgrade or replacement. Our diverse selection ensures that you can find the cover solution that best suits your specific application needs. From enhancing durability to maximizing functionality, we help you choose the best cover solution to meet your needs.
Upgrade your e-paper display and choose a cover from Jiaxian Electronics, which provides you with a cost-effective solution to enhance protection, clarity and functionality without breaking your budget. We use high-quality materials from well-known brands and offer low minimum order quantities (MOQs) and competitive prices to ensure that all your project needs are met.
Value-added options
Take your cover integration to the next level by adding a touchscreen or front light to your design. In the future, when your cover becomes damaged from normal wear and tear, you can simply replace the top film for a clean, shiny finish. By restoring the cover and top film coating, your cover will look like new again.
Here are some key points you need to know
The cover should be larger than the active area (AA) of the display and can be of various shapes.
Cover plates are typically made from a glass substrate that can be strengthened depending on the application requirements. Each type of cover plate material has unique strengths and properties.
Asahi Glass: Its strength and performance are more stable and less prone to cracking and breaking. Therefore, Asahi Glass is widely used in the automotive industry to manufacture key components such as windows and rearview mirrors.
Corning Glass: Corning's glass is harder and more resistant to abrasions and scratches than Asahi's, making it suitable for producing high-quality screens for smartphones, tablets, and other electronic products.
Overall, from the perspective of cost-effectiveness and practicality, we prefer Asahi Glass, and designers can choose the appropriate cover material according to specific application requirements. In order to obtain a better visual experience, for large-size e-paper displays, it is recommended to apply an anti-glare coating on the surface of the glass cover.
If transparency, hardness and abrasion resistance are not your key requirements, PMMA (polymethyl methacrylate) can also be used as an alternative cover material.
The cover thicknesses commonly used for electronic paper displays are 0.55mm, 0.7mm, 1.1mm, 1.8mm and 2.0mm.
The display cover is attached to the E-Ink display with tape or optically clear adhesive (OCA). OCA bonding ensures that the touch panel, cover, and E-Ink display are tightly bonded without smudging the display glass.
The OCA bonding process involves applying a thin layer of clear adhesive (approximately 0.005"-0.008" thick) around the bond line. This method is particularly useful for thin materials such as cover panels and touch screens. OCA bonding is applied in a thin sheet to ensure an even bond across the surface of the cover panel.
