Surface Protective Film for Optical Film and Sheet
Features and Applications
Features and Applications
A significant amount and varies of protective films are used during the whole manufacturing process procedure of display screen, which could be a window of a monitor, a smartphone, a touch panel, or a PSA. Among them, rather part of films are consumed by BLU (Backlight-unit)-the core component of display screen- and its compositive layers made of optically treated PC/PET/PMMA, etc, such as Light Guide Plate (LGP), Diffusing film and reflective film.
These delicate optical purpose-treated films and sheets are extremely vulnerable to extrinsic factors. Before assembling into an integrated BLU. they are expected to be pure homogeneous without any contamination and impurity, moreover, technical processed surfaces tend to be geometrically constructed Microscopically, all these require the protective film to be reliable competent with its performance at a much higher level than the ordinary.
Today displayer screens tend to be bigger, thinner, and curved, Generational upgrades and tech innovations happen in the curtate period, which presents a critical challenge for us to catch up with its evolving speed in respect of innovative strength and consistent quality improvement.
Donlee films are produced in 1000-10000 clean rooms and provide a series made of PE, PET, and OCA for different film and sheet applications. Basically, they share properties of good wetting adsorption, less adhesion building up, and easy to remove without any residue.
