A few words about liquid crystal film dispersed in polymer

Liquid crystal film dispersed in polymer[polymer dispereced Liquid Crystal film] It was invented in the USA in the 80s and since then it has been slowly gaining a foothold in the international market. It is widely used in the construction industry, especially in the medical field, because it allows to provide without curtains as the shading of external windows to prevent sunlight from entering, which in turn allows savings on the energy costs of air conditioning and on the other hand for the insulation of internal partitions when the personal space of patients must be ensured But on the other hand, it is necessary to monitor the patient. Tape is often used in intensive care units and operating rooms.

Frequent use from a household point of view as well In office spaces, when it is necessary to visually isolate the meeting room from the surrounding people. In the last decade, with the development of optical technology, it has found wide application in the advertising business. The point is that liquid crystal is exactly the crystal that is used in the production of televisions to produce images, film-dispersed crystal is very similar to the liquid crystal used in modern televisions, and most importantly, just like in the case of television, film-dispersed crystal has the ability to reflect images. Accordingly, if we stick the tape on the glass and illuminate the image from the other side with a projector, the tape stuck on the glass will work as a liquid crystal screen. This discovery was not missed by representatives of the advertising business, and they began to use liquid crystal film in the process of transforming the stained-glass windows of shopping malls and large stores into screens. In fact, liquid crystal film allows you to turn a shop window into a large screen that allows you to broadcast any content. There is no doubt that such a large-scale projection attracts a lot of attention and attracts customers. Moreover, currently the advertisement placed on stained glass windows is usually static and is simply pasted on the stained glass glass in the form of a sticker, therefore it requires constant updating and costs, in the case of liquid crystal film, this cost is one-time and allows you to change the content displayed on stained glass windows at any frequency, which, unlike a sticker, is interactive and therefore attracts significantly more user attention. behaves. Which, of course, adds its additional charm to the brand in which it is located, and in itself contributes to the increase in sales.

As mentioned above, the technology is based on Liquid crystals that have an elongated ellipsoidal shape and that are chaotically arranged in a film. As a result of the chaotic arrangement, the optical beam is blocked and it cannot reach beyond the film, therefore the film is cloudy in this state. But it is enough to supply a small electric charge to the polymer film, so that the crystals placed in it change their location and stop in a certain position, and since the crystal is ellipsoidal in shape, the charge received during the supply of electricity stops it in a position that allows an optical beam to pass through it, therefore the film becomes tough.
