PVC tempered film does have a certain impact on the clarity and color reproduction of screen display, and the degree of its impact is closely related to factors such as the manufacturing process of the tempered film, the degree of material improvement, and the user's use environment.
From the perspective of material characteristics, traditional PVC tempered film performs poorly in terms of light transmittance. The PVC material itself is thick, which causes a certain amount of refraction and scattering of light when passing through the tempered film, making the screen display look unclear, as if covered with a layer of gauze. Moreover, the light transmittance of PVC tempered film is difficult to reach the ideal state, and the light will be lost during the transmission process, which further reduces the display effect of the screen. In terms of color reproduction, traditional PVC tempered film also has problems. Due to the limitations of materials and processes, it cannot accurately restore the original color of the screen, resulting in deviations in the color displayed on the screen, reduced color saturation, weakened color layering, and the originally bright colors become dull.
With the continuous advancement of technology, the improved version of PVC tempered film has been improved in terms of light transmittance. By optimizing the material formula and production process, the manufacturer reduces the loss of light in the tempered film, making the screen display clearer. However, although the improved version of PVC tempered film has improved light transmittance, it still cannot completely eliminate the impact on the clarity of screen display. In a strong light environment, this impact will be more obvious, and the screen may reflect light, turn white, etc., affecting the user's viewing experience.
In terms of color reproduction, although the improved version of PVC tempered film has alleviated the problem of color deviation to a certain extent, it still cannot achieve the ideal effect. It still cannot completely restore the original color of the screen, especially in some scenes with high color requirements, such as watching high-definition movies and performing image processing, users can clearly feel the color difference.
In addition to the influence of materials and processes, the use environment of PVC tempered film will also affect its screen display clarity and color reproduction. In a high temperature environment, PVC material is prone to deformation, resulting in a decrease in the fit between the tempered film and the screen, and the formation of bubbles or gaps. This will not only affect the display effect of the screen, but also cause more refraction and scattering of light when passing through the tempered film, further reducing the clarity and color reproduction of the screen. In low temperature environments, PVC materials may become brittle and prone to cracks, which will also affect the display effect of the screen.
In addition, the quality of the oleophobic layer of the PVC tempered film will also affect the screen display. The main function of the oleophobic layer is to prevent fingerprints and oil stains from adhering to the screen and keep the screen clean. If the oleophobic layer is of poor quality, it is easy to be worn or fall off during use, causing the screen surface to be easily stained with fingerprints and oil stains. These stains will not only affect the beauty of the screen, but also affect the transmission of light, reducing the display clarity and color reproduction of the screen.
For users who have high requirements for screen display clarity and color reproduction, PVC tempered film may not be the best choice. They can consider choosing tempered films of other materials, such as tempered glass films. Tempered glass films have higher light transmittance and better color reproduction, which can more accurately restore the original color of the screen and provide a clearer and more realistic display effect. At the same time, tempered glass films also have better scratch resistance and wear resistance, which can effectively protect the screen.
