Touch Screen Integration & Display
Services
In addition to our touch screen product line, Dignity also offers touch
screen integration services to our customers. Touch screen integration bonds
the touch panel and sensor to the selected display in order to fix it in place
for final integration into a metal or plastic enclosure. Integration can offer
a wide range of benefits, but there are a number of considerations based on
enclosure design, end application, LCD structure, etc. A consultation with
Dignity’s experienced project team can help you determine the right solution
for your needs and then put that solution in place.

Dignity
offers the following options for touch screen and display integration:
Tape Bonding
Also
known as air gap or perimeter bonding, this is the simplest and most economical
way of adhering the touch panel to the display. This process takes place in our
cleanroom where we use a variety of industrial adhesive tapes and specialized
jigs/positioning frames to assist the process.
• Cost
effective solution to provide improved mechanical and environmental performance
at low costs
• Extremely
high yield rate and high reworkability
Dry Optical Bonding (OCA)
Dry optical bonding uses sheets of clear sheet
adhesive to completely fill the air gap between the display and touch panel and
enhance the performance of the assembly. A good mix of improved performance,
efficiency and cost competitiveness.
• Cost is considerably lower than LOCA, with good
performance for most applications
• Fast and easy integration process using pre-cut
sheet adhesive
• Similar optical and mechanical qualities to LOCA
bonding
Liquid Optical Bonding (LOCA)
Liquid optical bonding (or LOCA) is a bonding
method where the touch sensor is adhered directly to the display by using an
optically clear adhesive to form a direct bond without leaving any gap or space
between the two. It is generally the most expensive bonding option and is often
used for the most demanding or exacting environments, where performance is at a
premium.
• Superior optical qualities including better
contrast, better transmission, better readability and other aspects by removing
internal reflections between the display and the touch assembly.
• Superior mechanical properties, including better
adhesion, improved impact and vibration resistance
• Superior environmental resistance, including
extreme temperatures, elimination of contamination, fogging and condensation in
air gap
