Liquid Crystal Display (LCD) technology and display quality continues to evolve, while prices for LCDs have declined dramatically in the last few years. These two factors have helped to increase demand for LCDs in a variety of new and challenging applications, such as outdoor displays, where environmental conditions such as high ambient light and heat build-up can affect display quality. This has created a need for unique solutions to help extend the lifetime and display quality of LCDs in these conditions. One such solution is the use of UV blocking glass.
LCDs utilize organic components that are susceptible to ultraviolet degradation, which can manifest as a shift in color or a washed out look. Displays used in outdoor environments or in close proximity to Fluorescent black lights and other long wave UV emitters are at considerable risk of Ultraviolet degradation. Outdoor LCD devices are at high risk, but with more indoor UV emitter applications being developed it has become apparent that sunlight based ultraviolet radiation is not the only concern. Indoor UV emitter applications are being developed or are currently in use by medical and forensics groups for example.
The atmosphere itself blocks a significant portion of sunlight Ultraviolet radiation up to 280 nm, which is the top end of the UV C range. Oxygen is the primary element responsible for the atmospheres filtering effect on UV C. Indoor UV C emitters are in relative close proximity to the LCDs they would potentially affect and thus are not likely to benefit as much from the filtering effects of the atmosphere. UV C is also damaging to people and so high intensity emitters use protective barriers to contain the UV C radiation. For this reason, LCDs within the application would need a protective UV Blocking Glass.
UV B is less blocked by the atmosphere, but is still significantly blocked by ordinary glass (although this is not generally true for Silica or quartz glass). In situations where an application uses UV B radiation, it is recommended that the application be sealed to prevent excessive human exposure. Any application that needs an LCD to be exposed to UV B radiation regularly should utilize a UV Blocking Glass coating to ensure that the LCD does not degrade.
While ordinary glass blocks a significant portion of UV B this still leaves a significant portion of the UV A range that permeates the front of an LCD. It is this UV A range that has often eluded efforts to prevent ultraviolet degradation. Its effects are often not as obvious, but can be seen in many everyday situations where carpet, drapes or other natural and synthetic polymer objects are left in a window for long periods of time. They fade, crack or disintegrate due to the unblocked UV A radiation that passes through ordinary glass.
ZC&R’s UV Blocking Glass solutions act as a mirror to ultraviolet radiation. In combination with a hot mirror (IR Reflector), this coating helps preserve the performance of an LCD exposed to unfiltered broadband lighting while retaining the visibility and clarity of the display.
Before we get into specifics about how this would work, it is important to understand that liquid crystal display panels and polarizers utilize organic compounds that are susceptible to high heat and light energy stress. These organic compounds will eventually break down if deployed in high stress environments. One such contributing factor to LCD panel failure is the use of a high energy unfiltered illuminator. The near IR and shorter UV wavelengths not only add excess heat that may overheat the liquid crystal and prevent them from working properly, but they also add UV band energy that is destructive to organic compounds.
Over time the UV and IR will degrade and damage the LCD panel and polarizers to the point that they produce an unacceptably poor performance. In most applications this is observed to be color shift, washed out images and an observable raise in the darkness levels produced by a damaged LCD panel.
In order to help prolong the onset of such damage a set of UV and IR band filters and mirrors can be used to minimize the amount of harmful energy that is conveyed to the LCD panel from the illuminator. In order to determine what combination of filters and mirrors are best for any particular application it is important to know how each material reacts to the various intensities of bandwidths emitted by your chosen illuminator.
Frequently the Illuminators used in LCD systems are gas discharge lamps such as xenon arc lamps and metal halide light sources. A standard hot mirror that reflects energy between 750 and 1200 nm can be used to mitigate the majority of IR energy being conveyed to the LCD panel. In addition a UV blocker can be used to mitigate the damage from energy below 400 nm.
Other thin film coatings and substrates can be utilized to reduce the IR and UV damage to an LCD panel. Any solution must be well researched to minimize concerns so that a sufficient cooling mechanism is planned and allowed for in the application.

Ultraviolet (UV) light-emitting diode (LED) curing offers many benefits for bonding and coating applications in the touchscreen manufacturing segment. It provides a more consistent and reliable process without damaging or discoloring heat-sensitive components.
UV curing is a photopolymerization process that uses UV energy to change a liquid to a solid. Upon absorption of the UV energy, the photoinitiator (PI) produces free radicals that initiate crosslinking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink, coating, or adhesive, usually in a few seconds (see Figure 1).
Originally introduced in the 1960s, today’s manufacturers use UV curing for a variety of applications—from graphic arts printing to automotive headlamp coating and more. In fact, the UV curing market continues to grow as it displaces water- and solvent-based thermal drying processes due to increased productivity, higher quality and performance, and environmental benefits.
LEDs for UV curing applications generate UV energy in an entirely different way. As an electric current (electrons) moves through a semiconductor device called a diode, it emits energy in the form of photons. The specific materials in the diode determine the wavelengths of these photons. In the case of UV LEDs, the output is typically in a very narrow band (± 10 nm). Figure 2 compares the output of a 395-nm UV LED lamp with a typical mercury arc lamp. It is important to note the difference in intensity and wavelength of the output—both are important to understanding a UV curing process.
UV LEDs have been commercially available for more than 10 years. However, their unique output characteristics require newly formulated UV chemistries in order to take advantage of UV LED’s many benefits. For efficient and effective UV curing of an ink, coating or adhesive, the formulator needs to overlap the UV lamp output with the spectral absorption of the photoinitiator. A very efficient cure is possible with a formulation designed specifically for UV LED curing using a photoinitiator with concentrated absorption in the UV-A range.
UV chemistries for electronics applications are typically acrylates, silicones or epoxy formulations; acrylates are the primary choice because they generally cure more quickly. Many formulations are one-part, which makes handling and application simple. Most UV formulations are 100% solids with no solvent emissions, and are available in a range of viscosities depending on application needs. Shelf life varies from six months to several years.
Some UV formulations, especially those for bonding or encapsulating (where the UV energy cannot reach everywhere due to shadow areas) use dual-cure mechanisms such as UV with heat or moisture curing. UV adhesives can adhere dissimilar materials, such as metal, glass and plastics, with precision dispensing via syringe.
The touchscreen market continues to grow; uses include smart phones, tablets, eBook readers, mobile game consoles, and in-car navigation systems. Asia-Pacific is the largest and fastest growing regional market for touchscreen manufacturing.
A touchscreen display is an assembly of many different layers, such as the liquid crystal display (LCD) or organic light emitting diode (OLED), glass, conductive and non-conductive layers, and a protective flexible layer. Each of these layers needs a liquid optically clear adhesive (LOCA) to provide a strong bond, a protective seal from moisture, and desirable optical properties while withstanding sunlight.
UV LED-curable adhesive formulations are typically acrylic or epoxy cured at 365 nm, and deliver excellent optical properties such as light transmission, reduced reflections, anti-fogging, and impact and scratch resistance. They are easy to dispense and provide high flexibility without shrinkage or tension between layers, which could cause image distortion.
The manufacture of LCD and OLED displays also uses UV LED curing prior to assembly into a touchscreen. The low heat and on-demand curing using UV LED lamps is especially advantageous for preventing damage to sensitive components and delivering a consistent, high-speed process. One specific application is the edge sealing of OLEDs, which uses an epoxy resin and spot-curing UV LED system to deliver a precise and efficient cure that effectively seals out moisture. UV LED curing offers many benefits to electronics manufacturing, most notably improved yield, process stability and better adhesion.
Yield is improved with UV LED curing systems by providing consistent UV output over long periods of time. The display material receives a homogenous dose of UV energy consistently across the surface with no “hot” or “dead” spots that would lead to rejects.
UV LED systems provide stable output over long periods of time, typically greater than 20,000 hours. At the low power levels needed for display manufacturing, it is conceivable that the UV LED systems would last beyond 40,000 hours, with the only maintenance being monthly checks of air filtration and ensuring the emitting window is clean. Being semiconductor devices, UV LED systems can be turned on and off instantly with no damage to the light source. No warm-up or cool-down period is required.
The consistent output and long life lead to process stability, a key requirement for high-volume manufacturing. Knowing the equipment is consistently producing the same UV output allows vendors to focus their resources on other parts of the manufacturing process. Process stability is further aided by the fact UV LED systems only produce output in the UV-A range, typically 365 nm, to match with the acrylic adhesive being used. Since no UV-C or infrared is being produced, the adhesive and surrounding transport are only receiving the amount of dose in the wavelength required. This UV LED “cold cure” again improves process stability by not damaging the electronic components while the UV adhesive is being cured.
Since UV LEDs provide energy in a narrow band, a wavelength-optimized adhesive can be formulated to ensure deep-through curing and attachment to display surfaces. The adhesive manufacturer can depend on UV LED’s consistent output at a specific wavelength to develop a formulation that is highly reactive to the UV energy and thus shorten the curing time. Future developments of UV adhesives may also mean less adhesive is used for each display screen, leading to an additional cost savings to the manufacturer.
UV LED curing offers electronics manufacturers higher yield rates and productivity due to a consistent and stable process with less damage to heat-sensitive components. UV LEDs require very little space, making them easy to integrate into small spaces. Since UV LEDs produce no ozone emissions or hazardous waste concerns, they are environmentally friendly and safe.
Electronics adhesives and coatings suppliers have formulations available for use with UV LED curing that are easy to handle and apply in the precision, high-speed processes that are so common in electronics manufacturing. Many electronic product manufacturers are already reaping the benefits of using UV LED curing to improve their manufacturing processes.

Have you ever experienced "We considered the introduction of a UV LED light source, but abandoned the idea because of insufficient curing with existing inks"? It may be due to "oxygen inhibition" caused by the combination of radicals generated by UV irradiation with atmospheric oxygen.
Kyocera has developed a UV LED Light Source that realizes excellent curing performance without relying only on power such as irradiance and integrated (or accumulated) light amount, in particular, against "oxygen inhibition" known as poor curing of the ink surface.
Excellent curing performance even for inks and resins that are difficult to cure with conventional UV LED light source, such as low migration inks, coat varnishes, and inks for metal halide lamps.
Unlike the conventional nitrogen purging system that requires an enclosed space, G5AN/G5HN can efficiently flow nitrogen and reduce oxygen concentration in UV irradiation area simply by installing it in the system. No major modification to the system is required to create an enclosed space. A separate nitrogen supply source such as a nitrogen generator is required.
