Summary: Is a laptop screen film good? Most users will ask for a film when buying a laptop, but will the film bring good effects to our use, or will it cause any impact? Should we apply a film? Let's take a look.

Is a laptop screen film good?

A shell film has a discount on wireless signals

Attention to film sticking : Metal and carbon fiber films will attenuate wireless signals

The wireless network card antenna of most metal notebooks is set at the front of the A case (the top part of the screen) - PC manufacturers generally use plastic cases in this part (This is why metal laptops always have "a separate plastic shell" outside the top of the screen). If a metal film is attached to the entire A side, the wireless signal will be easily blocked, resulting in signal attenuation.

Keyboard film does not dissipate heat well and the temperature is high

Note on film application: Do not use keyboard film on notebooks that do not allow air to enter the keyboard

Keyboard film is the most common film. It can not only reduce the probability of liquid splashing into the machine and cause malfunction, but also prevent dust from accumulating in the gaps of the keyboard. However, not all notebooks are suitable for keyboard membranes.

For these models whose C-side is responsible for heat dissipation, using a keyboard membrane will undoubtedly cut off the air exchange channel, thereby affecting the heat dissipation effect of the entire machine. Therefore, if you find that the internal temperature of your notebook has increased significantly after using the keyboard film (you can use testing software such as Master Lu to check the changes before and after), you should consider removing the keyboard film.

Screen film and keyboard indentations are easy to show

Note on film application: The gap between the screen and keyboard may be smaller than the thickness of the film

A good screen has left a few keyboard indentations. Many people will be glad that they used a keyboard film and a screen film. Otherwise, the screen would leave permanent marks. In fact, you did it backwards - these indentations are caused by the keyboard film and screen film.

Therefore, before we install the keyboard film and screen film, we must pay special attention to the distance between the keyboard surface and the screen. The method is also very simple. After laying the keyboard membrane, draw a mark on the keyboard membrane with a watercolor pen, then cover the laptop screen, press it slightly, and then printOpen the notebook. If there are watercolor marks on the screen at this time, it means that the keyboard film has touched the screen. If this is the case, quickly remove the keyboard film or replace it with a thinner keyboard film.

How to choose a laptop film

Nowadays, there are many kinds of laptop films on the market. The prices of screen films of different materials are different, and the materials used in different screen films are different. The adsorption methods, light transmittance, color, hardness, etc. are also different. So, how should we choose a screen film suitable for our laptop?

1. Film material

In the market, there are many types of laptop screen films, and it is a mixed bag. When purchasing, , first of all, we need to find out the film material. Usually, regular films are marked with material. It is recommended that you choose films made of PET and ARM materials. These materials are better and can provide better effects. Don't be greedy for cheap and choose PVC or even PP films.

2. Film hardness

Generally speaking, the thickness of mainstream screen films can reach 0.3mm, and the hardness must reach 3H or above to effectively protect the notebook screen. When you buy a screen film, you can tear off the backing 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

Different films use different adsorption methods. For example, some use ordinary glue to adsorb, which will leave traces over time; Using special adhesives, they have high strength and are not easy to tear off; some use electrostatic adsorption, which can be torn off without leaving traces and can be used repeatedly. When purchasing a B-side film, try to choose a film that is electrostatically adsorbed and do not choose a film containing glue, otherwise it may cause unexpected trouble to your notebook screen.

　4. Light transmittance and color

Light transmittance is one of the important parameters for measuring notebook films, especially for screen films. Only when the light transmittance reaches more than 90% can you get a good quality film. To improve the visual effect, the light transmittance of high-quality films can generally reach more than 90%, or even 98%; while the light transmittance of inferior films is generally less than 90%. Regarding the color of the screen film, be careful not to have distortion, reflection, or “rainbow lines”. 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 allows for a tighter fit and prevents bubbles from forming. When choosing a screen film product, it is best to choose a film product that comes with cleaning tools, such as cleaning fluid, cleaning cloth, and some sticky films.

In addition, the selected screen film itself should have anti-static function to avoid dust accumulation.

As long as you pay attention to the above points, I believe you will buy a notebook film you love.
