Curved screen protector

The present invention relates to a protective film for an electronic device, and more particularly to a curved screen protective film suitable for protecting a curved display configured by an electronic device.

With the rapid development and advancement of electronic and semiconductor technologies, various types of mobile devices and wearable devices, such as notebook computers, tablet computers, tablet phones, smart phones, smart watches, and smart bracelets, have already penetrated into modern times. People are living.

In the early days, the screens of these devices were mainly flat-panel displays. In order to keep the surface of the screen flat, it was not damaged during the use or carrying of the device. Especially these screens are almost touch screens, which is easy because of the long-term. Frequent touches and frictions cause wear and tear, so a soft or hard protective film is attached to the surface of the screen to prevent damage to the screen while maintaining good flatness and display quality.

In the case of a hard protective film, the structure is usually a multi-layered bonding structure, which is formed by first forming a layer of silicone on a whole piece of PET substrate, and then cutting into a plurality of small substrates after slitting, and then Each of the PET substrates is adhered to the surface of the hard film by a transparent optical adhesive (OCA) to form a transparent multi-layer adhesive structure.

But with the evolution and breakthrough of display technology, and based on allowing users to have a better visual experience when viewing, or to make the appearance of the device more design, or for limited Reasons for increasing the overall display area in the device space, the screens on mobile devices and wearable devices are no longer the traditional flat shape, and they are beginning to be transformed into various non-planar curved screens. Therefore, the conventional screen protection film is of course required. Remade as a curved protective film.

Compared with the planar hard protective film, the manufacturing process of the curved hard protective film must strictly control the tolerance and deformation between each curved material to ensure the quality of the final laminated product and obtain acceptable. The yield, which of course makes the bonding between the multi-layer curved materials becomes extremely difficult, in addition to the problems of numerous processes and difficult to control the yield, it also leads to an increase in the overall manufacturing cost.

Therefore, in order to overcome these shortcomings in the conventional hard surface protective film technology, the applicant has carefully tested and researched, and has a persevering spirit to finally conceive the "curtain screen protective film" of the case, which can overcome the above shortcomings. A brief description of the creation.

Therefore, the curved screen protective film structure of the present invention does not need to be repeatedly implemented in the manufacturing process. Many times the cooperation industry, so can reduce the overall processing times of the protective film, and can completely avoid the problems of interlayer tolerance, interlayer alignment, arc-shaped surface not easy to fit, bubble generation and deformation, which are often encountered in the conventional bonding industry. It also leads to an increase in yield and a reduction in overall manufacturing costs while maintaining the performance of the prior art on the screen.

The present invention provides a curved screen protection film for protecting a curved screen on an electronic device, comprising: a curved substrate having a light transmissive and rigid substrate; and an adsorption layer coupled thereto The curved substrate is integrally formed and combined to form the curved screen protection film.
