Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a screen protective film. Background Art

[0002] The car's central control is where you control the car's air conditioning, audio and other comfort and entertainment devices. The car's central control includes a central control door lock system, through which the driver can control the vehicle's door switches and glass lifting system. High-end models are usually equipped with a large central control screen. In order to avoid scratches on the large central control screen, users will stick a layer of protective film on the large central control screen. However, existing protective films for large central control screens in cars have some problems, such as the screen is too large to be installed, and it is easy to see the screen content unclearly under strong light, leading to safety hazards.
