protection screen

privacy screen

A panel placed over a computer screen that limits its angle of vision to a front view so that visitors in the room cannot casually see the display. Also called a "privacy filter," it also may help prevent scratches and abrasions as well as improve contrast. See boss screen.

screen protector

A transparent, plastic film or liquid that covers the screens of smartphones, tablets and laptops to protect them from scratches and damage. With ultra-thin laptops, the keyboard can press against the closed lid, leaving permanent marks on the screen. In such cases, a piece of leather or soft cloth can be placed over the keyboard before closing.

The first protectors were a thin, inexpensive self-adhesive film made from polyethylene terephthalate (PET). They provided a high level of scratch resistance but little impact protection. Some manufacturers sold PET sheets that users cut themselves to fit their phones, but most were sold pre-cut to specific phone models.

The next advancement was thermoplastic polyurethane (TPU), which offered greater impact protection. Although TPU would absorb low-level impacts, its gel-like feel increased the resistance users felt when moving their finger across the screen. Sometimes an impact would dent the protector, but it was elastic enough to regain its shape over time.

Tempered Glass
Tempered glass was the first major improvement. Although initially expensive, it provided high-level impact and scratch protection without compromising on the feel of the screen. Custom cuts are mandatory; however, the protection varies with the quality of the glass.

Liquid Glass
Liquid screen protection (LSP) is unique. Rather than creating a new layer on top of the screen, LSP strengthens the screen itself. A silicon dioxide solution suspended in alcohol is wiped onto the screen surface by the end user. As the alcohol evaporates, the silicon dioxide sinks into the pores and imperfections in the glass. Over the next 24 hours, the silicon dioxide permanently bonds with the glass leaving a flatter, stronger surface. Providing as much or even a bit more protection than tempered glass, it does not change the aesthetics of the device.

I phoned Coun Paula Smith and she informed me that she had only been informed two days earlier that the contractors on site, having been made to erect a 6ft protection screen around the tree as part of the planning agreement their workers, had accidentally chopped through the roots and the tree was in immediate danger of collapse.
The presented solution is a manual one, so, for exchanging of the cutting insert, it is needed a longer interruption of the cutting process (all the movements of the machine's tool mobile elements must be stopped, the protection screen must be opened, the rotation must be done manually, and, after that the machining cycle can be restarted).
