How to Check if a Screen Protector is Good: A Complete Guide

You need a good screen protector to keep your screen from getting scratched, cracked, or otherwise messed up. Whether you’re a regular person, a store owner, or a screen protector maker, you need to know how to tell if a screen protector is good. Here’s how to do it.

Here’s how to check if a screen protector is good:

1. Figure Out What It’s Made Of: Is it made of tempered glass, PET, or TPU?
2. See If You Can See Through It: Can you see your screen clearly, and does it still look bright?
3. Test How Well It Works When You Touch It: Does it still feel smooth and work right when you touch it?
4. Make Sure It Sticks: Does it stick to your screen without any bubbles or gaps?
5. Check How Strong It Is: Does it get scratched or break when you try to scratch it or drop it?
6. Look for Extra Stuff: Does it have an oleophobic coating, does it work with your phone, is it easy to put on, does it have a nice edge, and does it come with a warranty?

Alright, let me break down the process of quality inspection for different types of screen protectors.

1. Tempered Glass Check Process:

HD CLEAR Tempered Glass Check Process:

1. Transparency Test: Make sure the glass is crystal clear and doesn’t mess with the brightness or color of the screen.
2. Scratch Test: Use keys or coins to lightly scratch the surface. Good quality HD clear tempered glass should be able to handle everyday objects without getting scratched.
3. Touch Sensitivity Test: Swipe, type, and do multi-touch actions to make sure there’s no lag or missed inputs.
4. Adhesion Test: Smoothly apply the protector using an installation kit. Check for air bubbles or gaps around the edges.
5. Durability Test: Drop small objects like pens or coins from a short height onto the protector to see if it can handle minor impacts without cracking.

Privacy Tempered Glass Check Process:

1. Privacy Angle Test: Tilt your device at different angles to make sure the screen content becomes hidden from side views but remains clear when you look at it straight on.
2. Transparency Test: Make sure the privacy layer doesn’t make the screen too dark or blurry when you look at it head-on.
3. Touch Sensitivity Test: Make sure the touch response is smooth and accurate even with the extra privacy layer.
4. Adhesion and Durability Tests: Do the same steps as with HD clear tempered glass to check the adhesion and durability.

Anti-blue Light Tempered Glass Check Process:

1. Blue Light Filter Test: Use a blue light filter test card or app to make sure the protector actually reduces blue light.
2. Transparency and Clarity Test: Make sure the anti-blue light coating doesn’t mess with the colors or clarity of the screen.
3. Touch Sensitivity Test: Do touch gestures to make sure the touch sensitivity isn’t affected by the anti-blue light layer.
4. Adhesion and Durability Tests: Do the same steps as with HD clear tempered glass to check the adhesion and durability.

Anti-reflective Tempered Glass Check Process:

1. Anti-reflective Coating Test: Look at the screen under bright lights to make sure you can see it without any annoying reflections.
2. Transparency and Clarity Test: Make sure the anti-reflective coating doesn’t make the screen look dim or weird.
3. Touch Sensitivity Test: Make sure the touch screen still works great even with the anti-reflective layer on it.
4. Adhesion and Durability Tests: Do the same tests we do for our regular glass to make sure it sticks and doesn’t break.

2. PET Screen Protector Check Process:

HD CLEAR PET Screen Protector Check Process:

1. Transparency Test: Make sure you can see the screen clearly without it looking weird or dim.
2. Scratch Resistance Test: Try to scratch it with your keys or a coin. It shouldn’t get scratched up from normal use.
3. Flexibility Test: Bend it a little to make sure it doesn’t break.
4. Touch Sensitivity Test: Try using the touch screen with it on to make sure it still works great.
5. Adhesion Test: Put it on the screen and make sure it sticks without any bubbles or gaps around the edges.

Privacy PET Screen Protector Check Process:

1. Privacy Angle Test: Tilt your phone to the side and make sure people can’t see your screen, but you can still see it straight on.
2. Transparency/Clarity Tests: Make sure the privacy layer doesn’t make the screen look dim or weird when you’re looking straight at it.
3. Touch Sensitivity Tests: Make sure the touch screen still works great even with the privacy layer on it.
4. Adhesion/Durability Tests: Do the same tests we do for our regular PET protectors to make sure it sticks and doesn’t break.

Anti-blue Light PET Screen Protector Check Process:

1. Blue Light Filter Tests: Use blue light filter test card/app to make sure it actually reduces blue light.
2. Transparency/Clarity Tests: Make sure the anti-blue light coating doesn’t make the screen look weird or blurry.
3. Touch Sensitivity Tests: Make sure the touch screen still works well with the anti-blue light layer on top.
4. Adhesion/Durability Tests: Do the same tests we do for our regular clear screen protectors.

Anti-reflective PET Screen Protector Check Process:

1. Anti-reflective Coating Tests: Look at the screen under bright lights to make sure it doesn’t reflect too much and make it hard to see.
2. Transparency/Clarity Tests: Make sure the anti-reflective coating doesn’t make the screen look dim or change the colors.
3. Touch Sensitivity Tests: Make sure the touch screen still works well with the anti-reflective layer on top.
4. Adhesion/Durability Tests: Do the same tests we do for our regular clear screen protectors.

3. TPU Screen Protector Check Process:

HD CLEAR TPU Screen Protector Check Process:

1. Transparency Tests: Make sure you can see the screen clearly without it looking weird.
2. Scratch Resistance Tests : Use keys or coins to lightly scratch the surface to see if it gets messed up.
3. Flexibility/Self-Healing Properties Tests :Bend it a little to see if it bends back and if any scratches go away.
4. Touch Sensitivity Tests : Try different touch gestures to make sure it works like it should.
5. Adhesion/Durability Tests : Put it on the screen and look for bubbles or gaps around the edges.

Privacy TPU Screen Protector Check Process:

1. Privacy Angle Tests: Tilt the device to different angles to make sure people can’t see the screen from the side but you can see it straight on.
2. Transparency/Clarity Tests : Make sure the privacy layer doesn’t make the screen look too dark or blurry when you look straight at it.
3. Touch Sensitivity Tests : Make sure the touch screen still works well with the privacy layer on top.
4. Adhesion/Durability Tests : Do the same tests we do for our regular clear TPU screen protectors.
