Mini Led And LCD Optical Bonding Displays Adhesive Glue For Electronics And Automotive Touch Screen
What Do We Understand by Optical Bonding?
Optical bonding refers to the adhesive process applied to bond a haze-free and protective layer or cover screen to an LCD panel. The method helps eliminate or remove any air gaps that may exist or form between the two films or sheets. It, in turn, allows for an improved or enhanced screen visibility.
Additionally, optical bonding helps improve the readability of a display screen. It implies that it can eliminate issues such as fog formation of condensation on the inner surface. It can do so flawlessly even in high humidity conditions. Furthermore, optical bonding can prevent mirror-image on the screen caused due to reflection of the sun’s rays.
What are Various Advantages Provided by Optical Bonding?
Optical bonding brings numerous advantages that help in multiple ways. A few points of benefit associated with the process encompass the following:
• Advanced Display Functioning
Optical bonding allows for an accurate and fast response to touch and generates high clarity and contrast displays. It can do so even if the device operates at less power and lower temperatures.
• Supports Rugged Displays
Optical bonding prevents fogging and condensation in humid environmental conditions. It provides resistance to dirt, shock, vibration, and scratch. On top of that, it eliminates or reduces the necessity of custom cover glasses or protective enclosures.
• Improves Display Images
Optical bonding allows for clearer and high-resolution display quality over a long time. It enables ambient and low surface light reflection. Furthermore, it promotes a broader viewing angle and reduces the strain on the eyes due to reflection.
• Enhances User Experience
Optical bonding allows for fewer layers on a device. It facilitates a slimmer design and lightweight nature. It, in turn, allows for effortless installation, servicing, and integration. Additionally, optical bonding promotes multi-touch interaction with the display screen. It reduces multiple parallax effects, leading to precise touch alignment and decreased display lag.
What are the Various Adhesives Utilized for Optical Bonding?
Optical bonding methods primarily utilize three adhesives. It includes silicone, polyurethane, and epoxy. Among them, silicone is the most commonly used one. Its core properties of chemical reactivity, low conductivity, water repellence, and thermal stability make it possible. Moreover, silicone can form stable and durable watertight seals. The soft nature allows it to get reworked as many times as required. It helps create secure bonds even if they get damaged with time.
Various silicone solutions like liquid optically clear adhesive (LOCA) or optically clear resin (OCR) is the most suitable adhesives for optical bonding uses and applications. It can get owed to their beneficial properties. They include superior design flexibility and clarity.
The two adhesives also enable haze and UV resistance. On top of that, they remain clear and unclouded for a significant time and can withstand high-temperature conditions.
Besides silicone, epoxy and polyurethane can also get used. The former creates better bonds among the three types but cannot get reworked. On the other hand, the latter tends to get yellowish after continuous exposure to light.
