Loctite® Liquid Optically Clear Adhesives (LOCAs)

The primary function of an optically clear adhesive in a display is to eliminate reflection loss and/or glare caused by air gaps between touch panel layers.

The table on this page illustrates the clear performance and manufacturing advantages of LOCA over OCA tape, which will drive the rapid adoption of LOCA over the next several years.

Performance Comparison: LOCA vs OCA Tape

Benefits of LOCA

• improving the viewing experience – with LOCA and A/R glass you can increase contrast ratio by 400% in sunlight. Henkel has minimized loss due to reflection by matching the refractive index to glass and PMMA.

• increasing display ruggedness – for large gaps up to 1 mm, you can increase the falling ball impact resistance by up to 3X.

• Extending battery life – by reducing light loss due to reflection, the end user can get a superior viewing experience with less power consumption, greatly extending battery life.

• Extending display product life – LOCA makes a display more durable to heat, moisture and temperature cycling.

• Enabling thinner designs – LOCA will absorb the impact of a given load when compared to an assembly with an air gap, allowing for thinner designs while protecting the display surface.

Cover Lens Bonding

introduction

Bonding the cover lens to the touch panel sensor is generally straightforward when both are made of glass. Normally a fast curing, high strength, refractive index matched LOCA is desired and many are available that can meet the needs of the application. in this case, the key differentiators are often related to the manufacturing process, such as the LOCA application time, cure time and first pass manufacturing yield.

When using a plastic cover lens or film touch panel sensor, the plastic is more difficult to adhere to than the glass, and it has different coefficients of thermal expansion than the glass. This makes the application more challenging and a very high strength LOCA such as Loctite® 3193HS™ is typically required.

LOCA

introduction

As the end user’s expectation of the display’s appearance and durability increases, direct bonding is becoming more and more common. Direct bonding is much more challenging than cover lens bonding for a variety of reasons. First, the modulus of the LOCA must be low enough to prevent MURA on LCD displays, while the adhesion and tensile strength must be high enough to prevent delamination during RA testing. Next, higher gaps are required to achieve high impact strengths which normally require that a dam be used. Finally, the polarizer film that is the top layer of the LCD display modules is harder to bond than glass. Henkel has developed a variety of direct bonding adhesives that were specifically formulated to overcome these challenges and are used in mass production applications today.

Dam LOCAs

introduction

Dams are high viscosity materials that are refractive index matched to a fill LOCA and used to create cured-in-place gaskets to prevent the LOCA from flowing:

1. Out of the display assembly to minimize the cleaning rework required2. into the back light unit of a closed cell LCD module

Dams are normally used in direct bonding applications due to their higher gaps, but have also been used in cover lens bonding applications. These dams must have refractive indexes that are within 0.001 of the fill LOCA to ensure that no line is observed between the two if the dam will be in a visible area.

While the height to width ratio will not be as high as traditional dams, it is also possible to cure the dam LOCA immediately after dispensing it with a spot curing light source.

introduction

Henkel has developed two cleaners that are developed specifically for Loctite LOCAs. Loctite® SF 7190™ is a hand wipe cleaner designed to remove dust, finger prints and small cured particles of LOCA. This is a fast evaporating solvent that is designed for manual processes. Loctite® SF 7191™ is a slow evaporating, high flash point solvent that is designed for automated processes that will remove the LOCA after it has been fully cured.

These cleaners are compatible with all Loctite® LOCAs except:• Loctite® 3193HS™

• Any Loctite® LOCA on SiO2 hard coat

Cleaners

Typical Hand wipe Cleaning process1. Dip the clean cloth, cotton swab,

wipe, etc… into the cleaner.2. Manually wipe the surface,

removing the LOCA residue and other contaminations.

3. if necessary, perform a final wipe with isopropyl alcohol or ethanol to reduce the evaporation time.

Typical fully Cured Cleaning process1. Disassemble the display to expose the cured LOCA. This is normally done via a

wire cutting process.2. Soak the cured LOCA in the cleaner for an extended period, normally 0.5 to 2

hours, using a soaked cloth, dipping process or spraying process. The exposure time will vary by the LOCA type, thickness, substrate type, etc.

3. if needed, use a plastic squeegee to remove large areas of softened LOCA.4. if needed, Use Loctite® SF 7190™ hand wipe cleaner to remove any small cured

particles of LOCA.5. if needed, manually wipe surface with iPA or ethanol to reduce the evaporation time.

Curing Light Cure Acrylics (continued)

Benefits of All Loctite® LEd Curing Systems

Air Cooled Self contained system (no water cooling required).

Instant ON/OFF

Requires no warm-up time. Allows turning off between cure cycles, reducing energy costs.

Long Life Up to 10 times vs traditional arc-lamps.

Cold Light Light output has no infra-Red (iR) content, minimizing part heating and warping.

100% Usable Output

Unlike traditional arc-lamps, 100% of light output is within the adhesive’s curing spectrum.
