LOCA, used during the building of LCD displays, are the industry standards for assembling displays within certain size ranges and for particular end uses. They are commonly used in high-demand, mid-sized monitors in automotive and aerospace applications, among others.

The multiple-layer assembly approach using LOCAs results in dramatic improvements in brightness and clarity of images, minimizes or eliminates issues of light refraction, and improves the durability of the display.

For each of the causes noted for bubbles in LOCA, there exists a corresponding set of solutions or proper behaviors that can minimize or eliminate it.

Appropriate viscosity range of adhesive – Typically, lower viscosity adhesives allow for more effective degassing manufacturing steps and lower bubble entrapment.

Choice of a low-shrinkage material -- High shrinkage of the adhesive layer after application can result in the development of voids, which can appear as bubbles.

Choice of proper curing mechanism -- UV curable adhesives are generally more reliable and less susceptible to bubble formation. Thermal curing materials can cause adhesive flow and air gap generation.

Automated dispensing process -- Manual dispensing, as noted above, is inconsistent and prone to mistakes and potential voids in coating. The use of automation is an obvious solution.

Autoclave or vacuum during bonding process -- The incorporation of an autoclave stage or introduction of optimized vacuum conditions will result in more consistent thickness, curing, and proper degassing of the adhesive when bonded.

Degassing step before dispensing -- Degassing before application remains one of the most effective and simple approaches and can often be enough to eliminate bubble issues on its own.

Just wondering if anybody with an autoclave/vacuum laminator can tell me how they find it with the results and if they use a press to apply the OCA or just their hands and a roller? I"ve seen a few advertised but the seller is claiming the autoclave will not remove all bubbles if it"s not done with a dedicated vacuum machine.

Dell used Samsung LCD"s with Dupont Display Enhancement. Great screen but badly sealed around the edges so the medium leaks out and air bubbles occur between the LCD & Glass panel.

Turn the panel over so that you"re working on the front of the panel. Place the panel on a book or the edge of the table, so that the pins hang over the edge and don"t get damaged while you"re working on the panel.

Select the top film and orient the film so that the arrow on the film label points to the side of the panel with the pins, then peel the protective film layer off the bottom film. This is the side with the sticker.

Peel the adhesive release film away from one edge and apply that edge of the film to the top of the panel panel and press it down with your finger. Gradually peel back the adhesive release film and use the card or roller to work the air out from under the film. If you see an air bubble form, gradually lift the film past the bubble and then reapply.

Use the razor blade to trim the film to the left and right sides and the bottom of the panel. If the film hangs over the top of the viewable area of the panel, that"s fine, but do not try to trim it from the top side, as the IC and conductive traces are easily damaged.

Remove the white backing from the factory graphics and align the bottom edge to the panel. Make sure that the graphics are evenly spaced on the polarizing film. There should be approx 1/32" gap between the bottom side of the panel and the start of the black border. There should be approx 1/32" gap between the left and right sides of the glass, and the black border of the graphics. Stick down the bottom edge of the graphics.

If you’ve ever wondered how to get your screen protector on properly with none of those annoying bubbles or dust particles, then read on – this is the way to do it right! We’ve done a video explaining the process, but if you’re limited on bandwidth we’ve transcribed it below, too. It should be useful not only for the Galaxy Nexus, but also an iPhone screen protector and screen protectors for many other phones and tablets too.

So the first thing you want to do is minimise the amount of dust in the room. A lot of the time this just means choosing a room in your house that is the most clean and don’t suffer from drafts. You can also try other methods – for example, you can run a hot shower before you put on your screen protector, letting the steam in the air clean up a lot of the dust.

Finally, you’ll want to ensure your phone’s screen is clean and dust-free. Take a fresh cleaning cloth and clean the entire display, ensuring that any dust is entirely removed. You’ll also want to make sure there are no fingerprint smudges or grease, as these will be locked beneath the screen protector layer.

Once you’ve done that, it’s time to gather your materials and get started. You’ll need your phone or other device, your screen protector, and an applicator card – if your screen protector didn’t come with one, then a credit card is an excellent substitute.

First, take your screen protector and lie it on the display, without exposing the sticky side – you’re just lining it up to ensure that you know what the ideal position is.

When you’ve got it in your mind, you’re going to place the screen protector perpendicular to the bottom of the display. The sticky side you be facing away from you and the rigid side will be facing toward you.

Now, you’re going to start exposing the sticky part of the screen protector, by slowly pulling the rigid side forward and away from you. As the sticky section is exposed, you’ll need to use your other hand to push the screen protector flat onto the phone’s display. The idea is that you’ll roll it along slowly, so each part of the sticky side of the screen protector is only exposed to dust for a short space of time before it’s applied to the phone’s surface.

Once you’ve reached the end of the display, the screen protector should be on correctly. If there are a few bubbles, don’t panic – use your applicator card or credit card to push these forward until they are removed.

If something goes wrong – you’ve got too many bubbles, a bad piece of dust or the protector is on wonky, then you’ll need to try again. Stop what you’re doing, and slowly reverse the process, taking care not to stretch the material. Screen protectors often come in packs of two or three, so don’t be afraid to start from scratch if you’re confident about the procedure.

Once there are no bubbles, you’re done! Don’t worry too much if there are a few tiny bubbles – if you leave the phone overnight, these will disappear and you’ll be left with a perfectly applied screen protector.

Ever find a bubble on your phone’s screen protector that just seemed to have popped up out of nowhere? Bubbles trapped beneath your screen are a common problem that many phone users face. Unfortunately, bubbles are not just unattractive — they can also cause significant problems. Not taken care of properly, they can make your screen protector less efficient at protecting your phone. The question is: How do you get the bubble out? Case-Mate breaks down exactly how to get air bubbles out of a screen.

Bubbles form for a variety of reasons. Typically, they arise from spaces or cavities that form beneath the glue used to secure your screen protector onto the phone’s glass. Often, this is the result of improper application oreven microscopic dust and debris caught beneath. Oil from our fingertips is also a reason bubbles form.

Unfortunately, a bubble can appear many years later, even if you are super careful and apply the screen protector like a pro. Whether it’s due to pressure on the screen, caused by drops or mashing the screen too hard during games or texts, your screen can shift and cause a small bubble that grows over time.

Okay, so you have an annoying air bubble in your screen protector. The bigger question is, how do you get rid of it? Here are a few tips and bits of advice on removing air bubbles and preventing them from happening in the first place.

Before you apply or install your screen protector, be sure to set up a clean working space. Dust and small pieces of grit can cause a screen protector to bubble up, so this step is important. Make sure the working space is clean and that the screen itself has been wiped down with an alcohol pad. Also, don’t forget to wash your hands with soap, too, removing dirt and oils.

Having to remove a screen protector to readjust it can create bubbles. So do yourself a favor and patiently take the time to align the screen protector properly before your first application. If you get it right on the first go, you won’t have to deal with peeling it off after it has made contact. Ideally, you should let the screen protector form a seal before removing any bubbles, should they even pop up.

Even if you apply the screen protector perfectly aligned, bubbles can still form. If you do have a few bubbles, that’s okay. However, don’t just poke the bubble or try to smooth it out with your bare hand or fingers. Instead, use a plastic card, preferably one with a clean, hard edge without nicks. Clean the card, too, like in the first step. Then, push out each bubble from the center to the edge of the screen. Also, push in one direction if you can. This will ensure a firmer grip and eradicate the bubbles.

If you have a bubble along the edge of the screen protector, and a card won’t do the trick, try this method instead: Lift the nearest corner with a thin piece of plastic gently, keeping your fingers and natural oils away. This will help remove the bubble. Then, you can follow it up with the plastic card again, securing the screen protector back to the phone’s glass surface.

Have you tried all the above methods and still see bubbles? Then it may be time to replace your screen protector entirely. There are many reasons bubbles can appear, but sometimes it’s simply due to the glue’s age, failing as it deteriorates over time. If this is the case, it’s vital to replace the screen protector promptly.

Introducing theCase-Mate screen protector, designed with durable tempered glass that ensures your phone’s screen is shatterproof. In addition, this screen protector is so rigid and robust that it will absorb and disperse the force of impact, should you accidentally drop the phone.

Case-Mate carries a wide variety of sizes specifically made to fit makes and models. Are you looking for aniPhone 11 screen protectoror a screen protector for your Android phone? We carry a complete line-up for all kinds of phone brands and manufacturers.

Keywords:Ensure perfect adherence of anti-glare (AG) films to LCD, adhere anti-reflex (AR) films to LCD, using optically clear adhesive (OCA) in touchscreen manufacturing, diagnosis of functional film adherence, fuji prescale tests in functional film adherence

Summary:Adhering functional films to LCD screens such as anti-glare (AG), anti-reflex (AR) as well as using  optically clear adhesive (OCA) in touchscreens requires uniform pressure to avoid air bubbles, flexing, skewing and other film displacements. Using the Fuji Prescale Ultra-Low Pressure film helps in diagnosing and eliminating any adherence problems.

With the explosive spread of LCD devices on the market, companies look for ways to make their product better in any possible way. For this reason, manufacturers add various functional films to various LCD devices:

Improving visibility and durability of LCD screens involves adhering of Anti-Reflex (AR) films, Anti-Glare (AG) films. Producing touchscreen devices requires using optically clear adhesives to add the resistance or capacitive touch-sensitive films. All these functional films must be flawlessly joined with the base plate to ensure optimal visibility of the displayed information on the LCD.

The method of adhering functional films to the base plate uses rollers that must exert equal pressure throughout the contacting surface so that the functional film is evenly adhered onto the plate. However, in practice, ensuring even pressure is not easy. The larger the adhering surface, the larger the problems.

In some cases, the roller axis can deviate from its ideal perpendicular aligmnent to the plate"s movement vector. This can cause the functional layer to get skewed or wrinkled.

Also, if the roler axis is not ideally parallel to the base plate, the roller will exert more pressure on one end, and lesser adhesion pressure on the other side of the base plate. This can cause air bubbles or poor adhesion of the functional screen.

In order to avoid any imperfections during the manufacturing process, technicians must regularly monitor the roller-cover glass alignment to ensure proper adhesion of the functional films.

The best way to measure alignment is to measure the tactile pressure that the drum exerts on the cover glass using the Fuji Prescale Ultra Low Pressure (LLLW) prescale film, as shown on the illustration below:

The Fuji Prescale film is placed between the cover glass and roller. The roller then rotates to cover the entire surface of the cover glass. This will develop the Fuji Prescale film which then can offer easy and accurate visual inspection, or it can be fed into the FPD-8010E Pressure Mapping System for precise pressure measurement and visualization.

In this case, the roller was not exerting the nominal pressure throughout the surface. Although the pressure was enough to achieve adhesion of the functional layer, the lack of binding pressure resulted in poor adhesion of the functional layer. This defect will only be discovered during the lifetime of the product, which can result in material loss due to warranty claims.

Thanks to the timely usage of the Fuji Prescale film, this manufacturer ensures optimal production quality of the LCD assembly as well as standardized LCD quality throughout the manufactured volume.

In 2021, our phones are essentially extensions of ourselves. We use them to play games and listen to music, for work and for school, to send and receive calls (well, usually texts), and more. Modern-day smartphones are, for all intents and purposes, pocket-sized supercomputers that accompany us at all times. We store everything on them from irreplaceable photos to sensitive financial information. So, when it comes to protecting your device (and everything on it), you need a great defensive strategy in a screen protector—installed without air bubbles or other blemishes.

Starting with a tempered glass screen protector is a surefire slam dunk. As phones get more advanced and their screens become more sensitive, protecting your device is absolutely crucial if you don’t want your screen (and your phone) to be one and done. Twice as strong as the leading competitor, a BodyGuardz tempered glass screen protector is the best defense against accidental yet irreparable damage—and each one comes with everything you need to quickly and effectively install it at home.

Once your existing screen protector has been removed, it’s time to get to work. First, thoroughly clean your phone’s screen with the sanitizing wipe and remove any streaks with the microfiber cleaning cloth (both included). Next, gently tap your phone’s screen with the dust-removal stickers to take off any remaining dust particles. In order to avoid air bubbles forming under your phone screen protector, it’s essential to be extremely thorough when removing dust.

After cleaning your phone screen and removing any dust particles, it’s time to install your screen protector. Gently place the install guide on top of your device—ensuring the orientation of the screen protector and your phone match. Next, while holding the protector, peel off the plastic backer to expose the adhesive before carefully placing it on your phone screen. Once you’re sure the screen protector is aligned, gently yet firmly press and run your finger down the middle of the screen to begin adhesion, and remove the install guide. Then, using your finger and the microfiber cleaning cloth, push any remaining air bubbles to the edges of your screen.

If you’re still seeing air bubbles under your screen protector, it may be possible to remove them. First, try waiting a few hours—rogue air bubbles will often work themselves out. If after 24 hours they haven’t disappeared, there may still be dust particles on your phone screen beneath your protector. If that seems to be the case, you can try using the dust-removal stickers once more. Carefully lift up the corner of your screen protector closest to the remaining dust particles, place the sticky side of a dust-removal sticker against the piece of dust, and pull the sticker directly out.

Stubborn air bubbles still hindering your screen protector’s installation after you’ve exhausted all other options? You may need to install a new screen protector. If that’s necessary, we recommend ordering a free replacement (all BodyGuardz screen protectors come with free replacements for the life of your device). Once you receive your replacement, carefully lift one corner of the old protector, slowly peeling it off your device. Now you can install your brand-new replacement screen protector, courtesy of BodyGuardz.
