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. Today the majority of touch panels are small (< 4’’), resistive and capacitive touch panels that are used in mobile devices. These small touch panels are normally assembled using an optically clear double sided tape.

But the touch panel market is rapidly changing. As the average touch panel size increases with tablets and monitors becoming more common and the performance requirements of optically clear adhesives increases, Table 1 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

In mobile devices, laptops, tablets, monitors and television sets, the majority of the designs today do not have a touch panel and have at least one air gap between the cover glass and the LCD module. Over the next several years, the touch interface will become ubiquitous in displays and manufacturers will strive to improve the customer experience by:

• 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 (1.5) 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 straight forward when both are made of glass. Normally a fast curing, high strength, refractive index matched LOCA is desired and many are available which can meet the needs of the application. In this case, the key differentiators are often related to the manufacturing consideration 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 make the application more challenging and a very high strength LOCA such as Loctite® 3193HS is typically required.

Introduction

As the end users expectation of the displays 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 for this application and are used in mass production applications today.

Dam LOCAs

Introduction

Dams are high viscosity materials that are refractive index matched to an 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 low viscosity fill LOCA immediately after dispensing it with a spot curing light source to use the LOCA as both the dam and the fill.

Introduction

Effective cleaners are critical to ensuring that a manufacturing process has the lowest total cost of ownership. 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

Typical Hand wipe cleaning process1. Dip the clean cloth, q-tip, 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 IPA 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.

Henkel Process Capabilities

Henkel has hired dedicated process engineers to help you select the right equipment for your needs, coordinate making prototype parts and running process validation trials. If you would like to our support, please contact your local sales representative and they can coordinate your request. If you are new to Henkel, contact numbers are located on the back cover of this brochure.

Henkel Display Center

Small to Medium Size Lamination Equipment

As of January 2013, Henkel currently has five laminators that can laminate displays from 2 to 27” as shown in Table 1. In addition, Henkel is developing fully automated lamination process equipment for television sized displays. We currently have one prototype machine installed in Henkel Display Center in Shanghai and will have a second machine installed in early 2013.

Equipment Partner Operating Model

With each of our equipment partners, Henkel has purchased one or more mass production representative laminators. The laminating equipment is either located in a Henkel dedicated space at the partner’s facility or in a Henkel lab. Henkel has also funded a technician from our partner’s team to operate the equipment for Henkel. By locating the equipment in the partner’s facility and hiring an expert from the partners team to operate the equipment, it ensures that Henkel’s equipment has the maximum capability, productivity and availability as well as the fastest turn around time when custom tooling is required to create prototype parts.

As our partner improves their capability, Henkel will invest to ensure that our equipment maintains best-in-class capabilities.

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.

Tack curing — Loctite® LED Spot Cure System

LOCA Use: Curing light ideally suited for spot tacking on selected display area, creating fixture strength prior to transporting to final cure.
