In the dynamic landscape of rugged monitor and rugged display technology, where reliability and
performance are paramount, the bonding methods employed play a crucial role in defining the
durability and clarity of these essential tools. Among the array of bonding techniques, OCA
(Optically Clear Adhesive) bonding and LOCA (Liquid Optically Clear Adhesive) bonding stand
out for their precision, resilience, and optical clarity. In this exploration, we delve into these two
innovative bonding methods, shedding light on their principles and applications, with insights
from David Conkle, the Founder of ViewPoint Systems, a leading provider of rugged display and
rugged monitor solutions.
- OCA Bonding: Precision in Clarity
OCA bonding involves the use of an Optically Clear Adhesive film, meticulously applied between
the layers of the display panel and cover glass or touch sensor. This adhesive film is optically
transparent, ensuring minimal distortion or interference with the displayed content. The
precision application and curing process result in a strong, seamless bond that enhances
durability and optical clarity, making OCA bonding an ideal choice for rugged displays deployed
in demanding military and law enforcement environments.
Mr. Conkle elucidates the significance of OCA bonding, stating, “OCA bonding allows us to
achieve a perfect union between display layers while preserving optical clarity. By carefully
controlling the application process, we ensure that our rugged displays maintain pristine image
quality and touch sensitivity, even in the harshest conditions.” - LOCA Bonding: Enhancing Resilience with Liquid Precision
LOCA bonding, on the other hand, employs Liquid Optically Clear Adhesive, a liquid adhesive
applied in a controlled manner between the display panel and cover glass or touch sensor. Once
applied, the adhesive is cured using ultraviolet (UV) light, forming a robust, optically clear bond.
LOCA bonding offers several advantages, including enhanced impact resistance, improved
moisture resistance, and flexibility in design, making it a preferred choice for rugged displays in
military, industrial, and law enforcement applications.
Mr. Conkle underscores the benefits of LOCA bonding, remarking, “LOCA bonding enables us to
achieve a seamless, durable bond between display layers while enhancing resilience to
environmental factors. This method allows for greater design flexibility and ensures that our
rugged displays maintain optimal performance in challenging environments.”
Looking Ahead: Advancements in Bonding Technology
As the demand for rugged displays continues to evolve, innovation in bonding technology
remains pivotal in meeting the stringent requirements of various industries. David Conkle
envisions a future where advancements in OCA and LOCA bonding techniques further enhance
the resilience, clarity, and functionality of rugged displays, stating, “At ViewPoint Systems, we
are committed to pushing the boundaries of bonding technology to deliver monitors and
displays that exceed expectations. By leveraging the latest advancements, our rugged displays
offer unparalleled performance and durability.”
In conclusion, OCA bonding and LOCA bonding represent cutting-edge techniques in rugged
display manufacturing, each offering unique advantages in terms of precision, resilience, and
optical clarity. With leaders like ViewPoint Systems spearheading innovation in this field, the
future of rugged displays holds promise for even greater advancements and performance in the
most demanding environments.
