Screen protectors & tempered glass for every model

If you switch devices a lot, glasses win. On filtering quality alone, film does better.

If you move between devices often, glasses are the better choice: one pair covers your phone, tablet, laptop and any screen you use away from your desk. Film can’t match that.

But on blue light filtering alone, film performs better, for manufacturing reasons. Lenses have to be ground thin, stay clear and remain light, so they filter roughly 15–20% less blue light than film. Glasses also let light leak in from the sides and around the edges of the lenses. Film filters at the source and covers 100% of the screen (our blue light film cuts more than 85% of blue light, according to the datasheet). And because it’s on the screen rather than on you, everyone who uses that screen benefits.

A simple way to choose: if you work at one main screen most of the day, film is better value and filters more. If you switch devices all day, glasses are more convenient. You can also use both.

Anyone selling it as “no more eye strain” or “prevents eye disease” is overclaiming, and we say that as a manufacturer.

Eye research, including statements from the American Academy of Ophthalmology, shows that most screen-related eye strain comes from habits: staring too long, blinking less and focusing at one distance for hours. It isn’t caused by blue light itself, so film is not a cure that replaces resting your eyes.

So what does blue light film actually do? According to test results, it cuts more than 85% of the blue light from the screen and blocks UV. Research is solid that blue light in the evening disrupts sleep, so people who work at screens late at night benefit the most. There’s also an advantage few people know about: filtering with film doesn’t distort colors, unlike your device’s night mode, which turns the whole screen yellow.

Bottom line: it’s not a scam if you buy it with the right expectations. It really does cut blue light and block UV by the measured amounts, but for tired eyes you also need to change your habits. Take regular breaks and blink more often. Film reduces the strain, but it doesn’t replace rest.

Most of the market stops at 17 inches. MAXIMUM makes privacy film up to 35 inches, and no one else in Thailand does.

Search for privacy film on Shopee or Lazada and nearly everything you find is phone or laptop size, mostly 17 inches or smaller. For large monitors, office screens or customer-facing displays, there is almost nothing available.

MAXIMUM makes privacy film up to 35 inches, which no other maker in Thailand offers. We cut it to the exact size of your screen from a single piece. It blocks side views from about 60 degrees, keeps the image normal for the person in front (about 85% light transmission) and also filters blue light. It’s a good fit for accounting, finance, HR, service counters or any screen that only the user should see. Check prices with the calculator on our homepage. The table goes up to 35 inches; for anything larger, message us on LINE for a quote.

Car screens face the harshest conditions in Thailand. A car parked in the sun can get hotter than 70°C, which is more than ordinary film can handle.

We learned this through car-screen film R&D with a major carmaker and found three problems. The first is heat. In a car parked in the Thai sun, cabin temperatures can exceed 70°C, while ordinary film on the market only handles about 60°C. Car-screen film needs a higher-grade silicone adhesive, and TPU film shouldn’t be used on car screens at all. TPU is a soft film that expands and contracts with temperature, and after daily cycles of extreme heat and cooling, the screen looks hazier over time. The second is glare. Light enters a car from almost every direction, so car screens reflect much more than screens at home. The third is everyday use. The car screen is shared by the whole family, with small kids touching it and food in the car, so it scratches far more easily than a screen used by one person.

MAXIMUM car-screen film is developed from that R&D specifically for Thai conditions (our PET film is rated up to 120°C, according to the datasheet), and carmakers in Thailand have chosen us to produce their film. As for touch, our PET film is only 0.14 mm thick, so the touchscreen works normally. You can order it cut to your car model or screen size from a single piece, and we also supply OEM orders for manufacturers and dealerships.

Measure the width and length in centimeters, covering only the area you want protected. Those two numbers are all we need.

Use a tape measure or ruler to measure the full screen in centimeters, from the far left edge to the far right and from the top edge to the bottom. Our factory automatically leaves a margin of about 1 mm on each side so the film sits neatly without touching the bezel.

If you’re not sure you measured correctly, take a photo of the screen showing where you measured and send it to LINE @maximumshop. Our team will check it before production. We also have a step-by-step measuring guide with pictures.

It’s easier than you think, and you take on no risk: if it goes wrong, bring it to our shop and we’ll replace it and apply it for free.

That’s our installation guarantee. If you misalign it, get bubbles or can’t get it on, bring the film to our shop and we’ll give you a new sheet and apply it for free. We can do this because we make the film ourselves, so you can always try it yourself first and let us fix it if needed.

If you’d rather not do it yourself, you have two options: bring your device to our shop (The Street Ratchada, 3rd floor), or use our on-site installation service for orders of 5,000 THB or more. On-site fees start at 800 THB in Bangkok and Nonthaburi. For other provinces, our team will quote case by case.

For feel alone, most people prefer glass, and as a film manufacturer we’ll admit it.

Glass has the texture and glide closest to a bare screen, which is why most people prefer how it feels.

But the real question isn’t which one is better. It’s whether tempered glass is even available for your model. Glass is mass-produced for specific models and shops have to carry the stock, so you’ll only find it for popular or newly released models. If your device isn’t one of them, the option you actually have is PET film cut to size. You give up the feel of glass, but you get things glass can’t offer: a choice of properties (matte, blue light filter or privacy), a thinner profile, no risk of shattering, and availability for any model and size from a single piece.

Most brands you see for sale don’t make their own film. There are only two or three truly Thai factories in the whole country.

Here’s something most people outside the industry don’t know: most screen protector brands you see advertised are made in China and rebranded. Thai-owned factories that actually produce film number no more than two or three nationwide, and they usually won’t take OEM work unless the order is very large. That’s why small businesses find it so hard to get film made under their own brand.

MAXIMUM is one of the few Thai manufacturers still in production, and what makes us different is that we accept small orders. We’re set up for SMEs and organizations that want their own branded film or a custom spec without ordering tens of thousands of pieces. PET film has no minimum order. Tempered glass starts at 1,000 pieces per design or model. Send us your requirements on LINE @maximumshop.

Yes to both. Past projects include BTS Skytrain · BYD · Suvarnabhumi Airport · King Chulalongkorn Memorial Hospital

We have an on-site installation team for large screens and high-volume jobs. Past work includes BTS Skytrain information screens, BYD car screens, displays at Suvarnabhumi Airport and King Chulalongkorn Memorial Hospital. On-site service is available for orders of 5,000 THB or more, with fees starting at 800 THB in Bangkok and Nonthaburi. Other provinces are quoted based on the site.

We also handle the paperwork organizations need: a quotation before you order and a full tax invoice (InnovaplusMaximum Co., Ltd. is VAT-registered). Send the number of screens and the location to LINE @maximumshop and we’ll send you a quote.
