Privacy film started as a phone accessory: a way to keep the person next to you from reading your screen on a train, in a lift, or on a plane. Over the past two years, more of the inquiries we receive are for screens that are not phones — mostly laptops, tablets and in-car displays.
1. Laptops and tablets: a steady demand from hybrid work
Once people started handling contracts, payroll and HR files in cafes, airports and shared desks, laptop privacy filters moved from a niche item to a routine purchase. The requirements differ from phone film:
- Non-standard sizes: 13.3 / 14 / 15.6 / 16 in each need their own die-cut, and the aspect ratio varies (16:9, 16:10, 3:2) along with bezel width;
- Different mounting: magnetic strips, clips or bezel adhesive, each suited to a different device;
- Brightness loss matters more: the larger the panel, the more visible the drop caused by the privacy layer, so high-transmittance constructions are preferred;
- Frequently combined with blue-light filtering or AR coating.
2. In-car displays: anti-glare first, privacy second
Centre consoles and passenger-side screens are one of the faster-growing categories we quote on, with a different set of priorities:
- Anti-glare comes first — daytime reflections directly affect readability; anti-fingerprint is secondary;
- Passenger screens have a clear privacy requirement: rear-seat passengers should not be able to follow what is on the display;
- The environment is harsher: sustained heat and UV exposure inside a car place higher demands on the adhesive and hard-coat layers than a phone does;
- Irregular cut-outs are common — corners and radii should be measured on the actual panel, not copied from published specifications.
3. Which construction to choose
| Option | Characteristics | Typical devices |
|---|---|---|
| Magnetic privacy film | Removable, attached only when needed; touch and camera unaffected | Phones, tablets, laptops with a magnetic frame |
| Silk-screen privacy glass | Stable viewing-angle control, cost-effective, mature process | Phones and flat displays of conventional sizes |
| 360° privacy for large panels | Blocks side-to-side and up-down angles for wider coverage | Tablets, laptops, in-car displays |
Loss of brightness is inherent to privacy film. AR coating can be laminated to reduce it, but transmittance, privacy angle and cost have to be balanced per project.
4. Three things to settle before a non-phone project
- Acceptance criteria: privacy angle (30° or 45°, for example), transmittance, total thickness, and whether weathering tests are required;
- Sample before tooling: measure the actual panel for tolerances and radii; published specifications are only a first filter;
- Choose the adhesive for the environment: for in-car and permanent-bond applications, prioritise heat resistance and low residue.
If your project is a laptop, tablet, in-car or industrial display, send us the size, the use case and the estimated volume. kmore produces to order and can adjust privacy angle and transmittance to your acceptance criteria.
