A shell film wireless signal discount
Film Note: Metal and carbon fiber films will attenuate wireless signals
The wireless network card antenna of most metal notebooks is set on the front end of the shell. Front-end manufacturers generally use plastic shells in this part, which is why metal notebooks always have "a separate plastic shell" outside the top of the screen. If a metal film is attached to the whole side A, the wireless signal will be easily shielded, resulting in signal attenuation.
Poor heat dissipation of keyboard membrane, high temperature
Film Note: Do not use keyboard film for notebooks with air intake to the keyboard
Keyboard membrane is the most common membrane, it can not only reduce the probability of liquid splashing into the machine and cause failure, but also facilitate to prevent dust from accumulating in the gap of the keyboard, but not all notebooks are suitable for keyboard membranes.
For models with these surfaces responsible for heat dissipation, the use of keyboard membranes undoubtedly cuts off the air exchange channel, thus affecting the heat dissipation effect of the whole machine. Therefore, after you use the keyboard film, if you find that the internal temperature of the notebook has increased significantly, you can use detection software such as Master Lu to check the changes before and after, and you should consider removing the keyboard film.
Screen membrane keyboard indentation is easy to appear
Film Note: The gap between the screen and the keyboard may be smaller than the thickness of the film
A good screen leaves a few indentations of the keyboard. Many people will be glad that the keyboard film and screen film are used. Otherwise, the screen will leave permanent traces. Actually, you got it the other way around - these indentations are caused by the keyboard membrane and screen membrane.
Therefore, before installing the keyboard film and screen film, we should pay special attention to the distance between the keyboard surface and the screen. The method is also very simple. After covering the keyboard film, draw a mark on the keyboard film with a watercolor pen, then cover the notebook screen, press it a little, and then open the notebook. If there are watercolor marks on the screen at this time, then Indicates that the keyboard membrane has touched the screen. If so, quickly remove the keyboard membrane or switch to a thinner keyboard membrane.
How to choose notebook film
Nowadays, there are many kinds of notebook films on the market, the price of screen films of different materials is different, and the adsorption methods, light transmittance, color, hardness, etc. of different screen films are also different. So, how do we choose the screen film that suits our books?
1. Film material
In the market, there are many kinds of screen stickers for notebooks. When purchasing, you must first find out the material of the stickers. Usually, the formal film is marked with the material. It is recommended that you choose the film made of PET and ARM materials. These materials are better and can provide better results. Don't be greedy for cheap PVC or even PP film.
2. Film hardness
Generally speaking, the thickness of the mainstream screen film can reach 0.3mm, and the hardness can reach more than 3H to effectively protect the notebook screen. When buying screen film, you can tear off the bottom paper and surface layer at the corners, and feel the thickness of the film with your hands, as long as it is slightly thicker than ordinary paper.
3. Film stickiness
The adsorption methods used by different films are different. For example, some use ordinary glue for adsorption, which will leave traces after a long time; some use special adhesives, which have high strength and are not easy to tear off; some use electrostatic adsorption, tearing. It leaves no trace and can be used repeatedly. In the process of purchasing the B-side film, you should try to choose the film with electrostatic adsorption instead of the film with glue, otherwise it may bring unexpected trouble to your notebook screen.
4. Light transmittance, color
The light transmittance is one of the important parameters to measure the notebook film, especially the screen film. The light transmittance of more than 90% can obtain a good visual effect. %; while the transmittance of inferior film is generally less than 90%. For the color of the screen film, pay attention not to be distorted, reflective and have "rainbow pattern". When purchasing, you can observe it with the naked eye.
5. Film cleaning
Before we apply the film to the laptop screen, we first need to clean the screen. This will stick more tightly and prevent air bubbles from forming. When choosing screen film products, it is best to choose film products with cleaning tools, such as cleaning liquids, cleaning cloths, and sticky dust films.
In addition, the selected screen film itself should have anti-static function, so as not to collect dust.
As long as you pay attention to the above points, I believe that you can buy your favorite notebook film.
