backlight sheet

Types of backlight sheet

A backlight sheet is a thin sheet often used to diffuse or spread light evenly in applications such as LED lighting, displays, and backlighting. This sheet is essential in many industries because it provides uniform illumination and enhances visibility. Backlight sheets are divided into two main categories: light-diffusing sheets and light-guide panels.

Light-diffusing sheets are made from materials like acrylic or polycarbonate. These materials are embedded with light-diffusing particles or have micro-structures on their surfaces. The light-diffusing sheets work by scattering light coming from a source, which helps to distribute the light evenly. These sheets are popular for use in applications such as architectural lighting, skylights, and general-purpose diffusers. They are widely preferred because they are cost-effective and easy to fabricate.

On the other hand, light-guide panels are constructed using high-quality acrylic sheets. They are designed with optical patterns that are precisely engineered. The primary function of the light-guide panel is to direct and distribute light from an LED source that is typically placed at the edge. These panels are commonly used in LCD displays, computer monitors, and high-end backlit signage. They are mostly preferred because they provide high light transmission efficiency and can produce bright and uniform illumination.

Besides, there are other types of backlight sheets. For instance, transparent backlit film, which is a popular type of backlit sheet. This type of sheet is made from materials like polyester or polypropylene. It is usually printed on using both digital and traditional printing methods. The transparent backlit films are commonly used in applications such as backlit posters, advertisements, and lightboxes. They are preferred because they are lightweight, easy to install, and offer good color reproduction.

Another type is the non-woven backlit sheet. This is a decorative backlit sheet. It is made from a mixture of natural and synthetic fibers. The non-woven backlit sheets are designed to be easy to install and have a wide range of applications. They are used in applications such as decorative wall coverings, shades, and privacy screens. These sheets are popular because they are environmentally friendly and have a textured appearance.
