In the daily use of electronic devices such as mobile phones and tablets, tempered film has become an important accessory for protecting the screen. Tempered films of different thicknesses have significant differences in feel, light transmittance and protection ability. Understanding these differences will help users choose the right product according to their needs.
Thinner tempered film usually refers to products with a thickness between 0.1 mm and 0.2 mm. This type of tempered film performs well in terms of feel. Because of its extremely thin thickness, after being attached to the screen, it basically does not change the original light and thin texture of the device. Users can feel the delicate touch of the screen more clearly during operation, and the sliding operation is smoother and smoother, with almost no obvious sense of obstruction, which can bring an operating experience close to "bare metal". In terms of light transmittance, thin tempered film has fewer layers and thinner materials, so light is easier to penetrate, and the light transmittance is often higher, which can better restore the original color and brightness of the screen, making the display effect clearer and more realistic. However, the protection ability of thin tempered film is relatively weak. When facing strong impact or scratches from sharp objects, its buffering and resistance ability is limited, and it is easy to break or scratch. The protection effect of the screen is not as good as that of thick tempered film.
Moderately thick tempered film, generally between 0.2 mm and 0.3 mm, has achieved a good balance between hand feel, light transmittance and protection ability. In terms of hand feel, although it is slightly thicker than the extremely thin tempered film, it will not have a significant impact on the operating experience, and can still maintain a relatively comfortable touch, which will not make users feel that the operation is significantly hindered, and can provide a certain texture. In terms of light transmittance, moderately thick tempered film can still maintain a high light transmittance, the screen display effect is basically unaffected, and the color and brightness restoration is also excellent. In terms of protection ability, moderately thick tempered film has better impact resistance and scratch resistance, can withstand a certain degree of external impact and scratching, effectively reduce the risk of screen damage, and provide more reliable protection for the device screen. It is a more common choice for most users.
Thick tempered film, usually refers to products with a thickness of more than 0.3 mm, has the greatest advantage of protective ability. The thicker structure gives it stronger buffering and pressure resistance. When the device is hit or dropped, it can better disperse the impact force, greatly reduce the possibility of screen breakage, and provide all-round protection for the screen. However, in terms of hand feel, thicker tempered film will make the device significantly thicker, and it may feel less flexible when operating, especially for users who are used to operating thin and light devices, it may take some time to adapt. In terms of light transmittance, due to the increase in thickness, light penetration will be hindered to a certain extent, which may cause the color and brightness of the screen display to decrease slightly, and the visual effect is slightly inferior to that of thin and moderately thick tempered film.
Different thicknesses of tempered film will also affect the feel in edge processing. Thinner tempered film usually has a thinner edge, and the edge transition is natural after fitting the screen, and there will be no obvious rubbing feel; while thicker tempered film may be sharper if the edge is not properly processed, which is easy to scratch the hand during operation, affecting the user experience. Therefore, even if a thicker tempered film is selected, attention should be paid to its edge grinding process to ensure that the edges are round and smooth.
In addition to the direct physical property differences, tempered films of different thicknesses also differ in durability. Thin tempered films are more likely to have scratches, warping and other problems due to daily wear and tear, extrusion and other reasons during long-term use due to their thinner materials, and their service life is relatively short; moderately thick and thick tempered films, with better materials and structures, can maintain a good condition for a long time, are more durable, and have a relatively low replacement frequency.
In actual selection, users need to choose a tempered film of appropriate thickness according to their own usage habits and needs. If you pay attention to the operating feel and screen display effect, and pursue an experience close to the bare metal, thin tempered film is a good choice; if you want a more balanced performance in all aspects of performance, taking into account the feel, light transmittance and protection ability, moderately thick tempered film is more suitable; and for users who often need to use the device in a complex environment, or are worried that the device is easy to fall or collide, thicker tempered film can provide more reliable protection.
With the continuous advancement of technology, the performance of tempered film is also continuously optimized. In the future, new tempered film products with ultra-thin thickness, high light transmittance and super strong protection may appear. By adopting more advanced materials and processes, the limitations between thickness and performance of existing tempered films can be broken, bringing users a better user experience and meeting diverse market needs.
