In today’s hyper-connected world, screens are more than just components of our devices—they are the primary interface between us and our digital lives. Whether it’s smartphones, tablets, laptops, or even smartwatches, the durability of a screen plays a vital role in the longevity and usability of the device. Not all screens are created equal, and understanding what type of screen is the strongest can help consumers make informed decisions when purchasing electronics.
In this article, we’ll explore the most common and advanced screen materials used today, compare their strengths and weaknesses, and identify which material offers the strongest protection against everyday wear and tear—including drops, scratches, and impacts.
Understanding Screen Materials: A Brief Overview
Before diving into which screen is the strongest, it’s important to understand the materials commonly used in the construction of device screens. These materials vary in composition, durability, and performance.
Gorilla Glass
Gorilla Glass, developed by Corning, is one of the most widely used screen materials for smartphones and tablets. It’s known for its high resistance to scratches and impacts, especially in its newer iterations like Gorilla Glass Victus.
Sapphire Glass
Sapphire glass is often used in luxury phones and smartwatches due to its exceptional scratch resistance and optical clarity. It ranks second only to diamond on the Mohs scale of mineral hardness.
Plastic Screens (Polycarbonate & Polyethylene Terephthalate)
Plastic screens are commonly found in ruggedized devices and some entry-level phones. They offer flexibility and high impact resistance but are prone to scratching unless coated.
OLED Plastic Substrates
OLED screens often use flexible substrates like plastic in foldable devices. While not traditional “plastic screens,” they are designed for flexibility, which can contribute to durability in certain contexts.
Hybrid Materials and Innovations
Innovations in materials science have led to the development of hybrid materials like Ultra-Thin Glass (UTG) for foldable screens and reinforced composites that enhance both flexibility and strength.
Which Screen Material Is the Strongest? Comparing Key Features
To determine the strongest screen, we must compare several factors: scratch resistance, impact resistance, flexibility, and optical clarity.
Scratch Resistance
Sapphire glass is the clear winner when it comes to scratch resistance. With a hardness rating of 9 on the Mohs scale, it can resist scratches from almost any material except diamond or another sapphire. Gorilla Glass follows with varying levels of performance depending on the generation—Gorilla Glass Victus offers scratch resistance up to about 7 or 8 on the Mohs scale. Plastic screens, even when coated, are more susceptible to scratches.
Impact Resistance
Where impact resistance is concerned, Gorilla Glass Victus performs exceptionally well. In Corning’s tests, it survives drops from up to 2 meters, outperforming previous versions. Plastic screens, due to their flexible nature, can absorb impact better than rigid materials but are more likely to deform rather than break. Sapphire glass, although scratch-resistant, is more brittle and thus not as effective in high-impact scenarios.
Flexibility and Foldability
For devices that require flexibility—such as foldable smartphones—Ultra-Thin Glass is the material of choice. UTG combines the clarity and smooth surface of glass with the ability to bend repeatedly without breaking. Plastic substrates, while flexible, are not as durable over time and tend to show wear more easily.
Optical Clarity
Sapphire glass offers the best optical clarity and light transmission, making it ideal for premium devices where visual performance is critical. Gorilla Glass also provides excellent clarity, while plastic screens can suffer from inferior color fidelity and higher reflectivity.
The Contenders: A Detailed Comparison
| Screen Material | Scratch Resistance | Impact Resistance | Flexibility | Typical Use Cases |
|---|---|---|---|---|
| Gorilla Glass Victus | High | Very High | Low | Smartphones, Tablets, Laptops |
| Sapphire Glass | Extremely High | Moderate | Low | Smartwatches, Luxury Phones |
| Polycarbonate (Plastic) | Low (unless coated) | High | Moderate | Rugged Phones, Kids’ Devices |
| Ultra-Thin Glass (UTG) | High | High (when supported) | Very High | Foldable Phones, Wearables |
From this table, it’s evident that the strongest screen depends on the intended use of the device. For general smartphones requiring a balance of durability and clarity, Gorilla Glass Victus is currently the best option. For wearables where scratch resistance is paramount, sapphire glass wins. For rugged devices needing impact survival, plastic screens can be ideal. For foldables and next-gen phones, Ultra-Thin Glass proves superior.
Real-World Performance Tests and Industry Trends
To gauge how these materials hold up outside of lab tests, we can look at real-world benchmarks and lab simulations.
Dropping Tests
The popular YouTuber JerryRigEverything puts various devices through a series of tests involving a pick, fire, and drop simulation. The results have shown that newer Gorilla Glass Victus-equipped phones can survive 3-4 drops from waist height without breaking. Sapphire glass devices, while scratch-proof, often crack or shatter upon hitting hard surfaces like concrete.
Scratch Resistance Demonstrations
In side-by-side comparisons, sapphire glass remains unscathed even when scratched with materials like keys or sandpaper. In contrast, plastic-coated screens often accumulate visible marks after everyday use.
Flexibility and Longevity in Foldables
Foldable smartphones like the Samsung Galaxy Z Fold series use Ultra-Thin Glass as their top layer. In durability tests, these screens withstand thousands of folds. However, repeated creasing and sharp bending can still lead to micro-cracks over time. This highlights the importance of combining durability with proper usage habits.

What makes a screen strong and durable for devices like smartphones and tablets?
The strength and durability of a screen largely depend on the materials used in its construction and the technologies incorporated to enhance resilience. Most modern screens are made from a type of glass-ceramic composite engineered to have a balance of clarity and toughness. One of the most well-known materials used is Corning Gorilla Glass, which undergoes a chemical strengthening process called ion exchange. This process helps the glass resist scratches and withstand impact better than standard soda-lime glass.
In addition to the material, the structural design, lamination techniques, and coatings applied to the screen also contribute to overall durability. Manufacturers often bond the screen to the device’s chassis using strong adhesives and incorporate protective layers such as oleophobic coatings to reduce fingerprints and minor abrasions. Screens that are layered with materials like sapphire glass also offer increased resistance to shattering and scratching, though at a higher cost and weight.
Which are the most common types of strong screen materials used in modern devices?
The most common screen materials known for their strength include Corning Gorilla Glass variants, sapphire glass, and flexible OLED panels. Corning Gorilla Glass, in particular, has multiple generations with improved toughness—Gorilla Glass Victus being one of the latest versions, offering better drop and scratch resistance. These materials are widely used in smartphones, tablets, and wearable technology due to their balance between strength and optical clarity.
Sapphire glass, although less common due to its high cost and challenges in manufacturing, is another durable option that ranks second only to diamond in terms of hardness. It’s frequently used in luxury watches and high-end smartphones. Meanwhile, flexible OLED panels—used in devices like foldables—are designed with polymer substrates that can absorb shocks and resist cracks from bending, although they can still be damaged by puncture or excessive pressure.
What is the difference between Gorilla Glass and sapphire glass?
Gorilla Glass, manufactured by Corning, is a chemically strengthened alkali-aluminosilicate sheet glass that is both lightweight and thin, making it ideal for portable electronics like smartphones and tablets. It undergoes an ion exchange process that increases its surface strength. Gorilla Glass comes in different versions, each improving upon the previous in terms of impact resistance, scratch resistance, and durability, with Gorilla Glass Victus offering protection against drops from up to two meters and good resistance to scratches from materials like keys or sand.
Sapphire glass, on the other hand, is a crystalline material made from synthetic sapphire, which is extremely hard—second only to diamond on the Mohs hardness scale. This makes it highly resistant to scratches, ideal for applications like camera lenses, smartwatch faces, and high-end smartphone displays. However, it is heavier, more expensive, and more brittle than Gorilla Glass, meaning it can shatter more easily under forceful impact despite its scratch resistance.
Are flexible screens the strongest type of device screens?
Flexible screens, typically made using ultra-thin glass (UTG) or plastic-based OLED technology, are designed to bend rather than break under stress, making them highly resistant to cracks when folded properly. This ability to absorb force through bending gives them unique durability benefits, especially for foldable smartphones and wearable tech. However, while they can withstand repeated bending, these screens may be more susceptible to punctures, deep scratches, and long-term wear due to the softer protective layers used to maintain flexibility.
Unlike rigid screens such as sapphire or newer Gorilla Glass models, flexible screens may also experience screen fatigue over time, especially at the bending point. The protective films used on top of these displays are often more vulnerable, and repeated creasing can degrade image quality or cause small fractures. Therefore, while flexible screens are innovative and durable in specific situations, they are not necessarily the strongest when it comes to general impact or scratch resistance.
How does screen thickness affect screen strength?
Screen thickness does play a role in the overall strength and durability of a device’s display, but it’s not the only factor determining robustness. Generally, a thicker screen can absorb more impact and is less likely to crack under pressure compared to thinner alternatives. This is why ruggedized and industrial-grade devices often feature slightly thicker screens to enhance durability under harsh conditions.
However, in modern consumer electronics, there is a strong demand for thin, lightweight devices, so manufacturers have turned to advanced engineering and material science to enhance screen strength without increasing thickness. Thinner strengthened glass, like Gorilla Glass Victus, remains durable by being chemically treated and structurally reinforced. As a result, device makers must balance screen thickness with quality materials and construction methods to offer what is ultimately a strong, functional, and user-friendly screen.
What are some technologies used to increase screen durability?
To enhance screen durability, manufacturers use several technologies, such as ion exchange, lamination techniques, and protective coatings. Ion exchange is a chemical process used in glass like Gorilla Glass where smaller sodium ions in the glass are replaced with larger potassium ions. This forms a dense, compressive layer on the glass surface, making it more resistant to scratches and cracks.
Lamination techniques play a critical role as well. For example, using OCA (optically clear adhesive) layers between the display and the outer screen helps absorb shocks and reduces the chance of screen delamination, especially when the device is dropped. Protective coatings like oleophobic layers repel oils from fingerprints, which improves usability and reduces surface-level wear. Some manufacturers also integrate air cushioning into device frames and back panels to reduce the force of impact on the screen.
Can a screen protector make my screen stronger?
Yes, a high-quality screen protector can significantly improve your screen’s resistance to scratches, minor drops, and daily wear by acting as a sacrificial layer. Most screen protectors are made from tempered glass, plastic (PET), or hybrid materials and can absorb much of the shock that would otherwise be transferred to the original screen. Although they cannot make the screen completely shatterproof, they can help prevent minor damage and preserve the device’s resale value.
However, not all screen protectors are created equal. Tempered glass protectors are generally the most effective at preventing scratches and absorbing impact due to their hardness and thickness. Cheaper alternatives may offer less protection or reduce screen sensitivity and clarity. Proper application is also essential for optimal performance, so dust-free installation and alignment are key to achieving the best results.
