About this item

  • 【Package including】High Contrast linear polarizing film *1 + scraper*1 + dry wipe *1+moist wipe*1, ensures no air bubble in sticking.Wide Application for Motorcycle dashboard display, small-size screen, and electronic watch screen.
  • 【Professional-grade Performance】K&F Concept polarizing film utilizes specially crafted optical film from Nisshin, ensuring exceptional polarization performance with high transmission of unpolarized light from 380–700nm and a polarization rate of up to 99.99%.
  • 【Premium Specifications】The polarizing film sheet measures 7.8x11.8 inches (20x30cm) and boasts a thickness of 0.21mm. It features a protective film on both sides, with one side being adhesive and the other side non-adhesive (please remove the protective film on the adhesive side before use).
  • 【Easy Identification】Confirm the sticky side (tear a little protective film at the corners to confirm the stickiness, do not tear it all apart). The polarizing film is clearly labeled with red and blue stickers. The red sticker indicates the adhesive side, while the blue sticker indicates the non-adhesive side.
  • 【Simple Application】While keeping the power on, take the screen as the center point, the sticky side is overlapped on the screen, and the polarizing film rotates 360 degrees clockwise. Find a clear location, and mark the location. After cleaning the surface of any dust particles, cut the film to the desired shape and apply it for immediate use.
  • 【 Note】Why rotate? Each display film must be rotated to match the position, and each screen angle is different

The polarizing sheet was comparatively priced, manufactured well and worked very well with the experiments I wanted it for. the package surprised me with a free gift I did not expect to help keep it clean and keep it clear. I cannot see it being better for what I needed and expected

I accidentally nicked the LCD lens and thought I'd need a new machine: This film's resolution did as good as factory.

Adhesive worked well on glass with minimal problems with bubbles. Transparency and extinction were both as expected.

Nous avons longuement chercher une solution car le filtre polarisant de notre afficheur de véhicule avait fondu avec la chaleur, nous avons finalement trouvé ce filtre polarisant qui a réglé notre problème à moindre frais... Il pourra également servir pour d'autres fois au besoin. C'est un bon article que je recommande. Merci beaucoup

I chose this polarizing film in large part because of other brands reportedly arriving bent or damaged. While I can't attest to the quality of this sheet versus the others, the way it was packaged was proof the manufacturer wants you to receive the product the way it left the factory. I applied it to a piece if plexi and it went on easily as long as you follow the instructions and clean the surface first with the included alcohol wipes and smooth it with the included squeegee. Reasonable price and seems to work as I would expect.

This linear polarizing film is used often in my photographic studio. I cut it in half and covered the front of a couple LED panel lights in order to polarize the light for copying photographs and other objects. Then, when I put a high quality glass polarizing filter over my camera's lens I can eliminate unwanted reflections from shiny objects. This also helps to boost contrast.Being able to utilize this filter's self-adhesive-backing allowed me to adhere it directly to the panel lights' front diffusion panels.K&F also packages their polarizing filters better than other manufacturers by placing the filter between two sheets of styrofoam which gets put inside two sheets of cardboard which is then slid into its cardboard box.

Es ist schwer zu sagen, wie viele der negativen Erfahrungen, die andere Rezensenten beschrieben haben, auf das Produkt zurückzuführen sind, und wie viele auf eine falsche Verwendung zurückzuführen sind. Wenn ich diese Folie hochhalte und drehe, macht sie genau das, was ich von ihr erwarte. Reflexionen an einem Fenster verschwinden beispielsweise und tauchen dann wieder auf, wenn ich sie in verschiedenen Winkeln drehe. Es funktioniert einfach gut!Ich vermute, dass einige der Rezensenten nicht richtig auf die Polarisationsrichtung geachtet haben. Positionieren Sie dazu die Folie dort, wo sie verwendet werden soll, und drehen Sie sie, bis die Blendung durch die problematische Lichtquelle minimiert ist. Bringen Sie die Folie dann genau in diesem Winkel an und achten Sie darauf, die Schutzfolien von beiden Seiten der Folie zu entfernen. Es gibt zwei Schutzfolien!Beachten Sie, dass ein solcher Polarisator nur Reflexionen von Oberflächen reduziert, die von Ihnen weg geneigt sind. Das Spiegelbild, das Sie beispielsweise von sich selbst sehen, wird dadurch nie verschwinden, denn wenn Sie sich selbst sehen können, muss die Oberfläche parallel zu Ihnen sein.Polarisatoren tragen auch nicht dazu bei, die Blendung metallischer Oberflächen zu reduzieren, da diese Oberflächen das von ihnen reflektierte Licht nicht polarisieren.
