An LGP sheet (Light Guide Plate) is a transparent acrylic or polystyrene panel designed to distribute light evenly across its surface. LEDs are placed on the edges of the sheet, and the internal micro-dots or laser-etched patterns guide the light forward. This creates uniform brightness without dark spots, making it essential for signage, lightboxes, LED photo frames, and architectural lighting.

The most common materials are PMMA (acrylic) and PS (polystyrene). PMMA acrylic LGP sheets are premium, offering excellent transparency, high light transmission, and long-term durability without yellowing. PS LGP sheets, such as Plastiko LGP sheets, are more affordable, making them suitable for cost-sensitive projects where optical performance is less critical.

The most widely used size is 8×4 ft (feet), which is suitable for cutting into smaller panels. Standard thicknesses are 2 mm, 3 mm, and 4 mm, but sheets can also be manufactured in higher thicknesses depending on project needs. Choosing thickness depends on the span, lighting intensity, and rigidity required for the application.

Laser-dotted or V-cut patterns ensure that light is redirected evenly across the panel surface. Without these micro-patterns, light would escape through the sides, causing uneven brightness or visible LED spots. A good dotting pattern increases brightness, improves energy efficiency, and ensures a premium display quality for signage or LED frames.

Prices vary depending on thickness, material, and supplier. On average, LGP acrylic sheets range between ₹1,600 to ₹3,000 per sheet (8×4 ft size). Some budget-friendly PS LGP sheets can cost ₹40–₹65 per sq ft. Anand Plastics, for example, lists imported LGP sheets at ₹1,600/sheet onwards with a minimum order of 10 sheets.

A regular acrylic sheet is just a transparent panel without engineered light-guiding properties. In contrast, an LGP sheet has micro-etched dots or grooves that control light distribution. While normal acrylic may show hotspots from LEDs, LGP ensures uniform brightness across the entire surface, making it ideal for signage and backlit panels.

Yes, LGP sheets can be cut into custom dimensions using laser cutting, CNC routing, or precision sawing. However, it is essential that cutting maintains edge smoothness for optimal LED coupling. Suppliers like Anand Plastics offer cut-to-size services, ensuring the sheet matches your display frame dimensions perfectly.

Acrylic LGP (PMMA) offers superior light transmission, UV resistance, and long-term durability with minimal yellowing. Polystyrene (PS) LGP, such as Plastiko sheets, is more affordable and lightweight but may discolor or warp over time. For premium retail or architectural applications, acrylic is preferred, while PS is suitable for budget projects.

With proper handling, acrylic LGP sheets can last 7–10 years or more, depending on the installation environment. High-quality PMMA resists yellowing, scratches, and warping, making it ideal for long-term use. Lower-cost PS sheets may degrade faster, especially under direct UV exposure or heat from high-power LEDs.

In LED photo frames, an LGP sheet is placed behind the printed image. LEDs at the edges distribute light evenly through the LGP, illuminating the picture without shadows. This creates a slim, bright, and visually striking frame often used for commercial advertising, exhibitions, and decorative interior applications.

The MOQ depends on the supplier. For example, Anand Plastics offers a minimum order quantity of 10 sheets. Wholesale buyers often get discounts for bulk orders. Retail customers looking for single sheets may need to check specialized resellers who cut down from wholesale stocks.

Not exactly. While both manage light, LGP sheets distribute edge-lit LED light across a surface, whereas diffuser sheets soften direct LED light to avoid harsh glare. For uniform backlit panels, LGP sheets are better; for covering LED panels or ceilings, diffuser sheets may suffice. In many designs, both are used together for optimal results.

• 2 mm: Best for slim LED photo frames.
• 3 mm: Standard for signage and medium-sized lightboxes.
• 4 mm+: Recommended for larger panels needing rigidity.
  Thickness choice depends on sheet size, LED density, and frame design. Thicker sheets spread light more evenly but increase cost and weight.

LGP sheets are widely used in advertising signboards, retail lightboxes, LED photo frames, decorative wall panels, menu boards, airport signage, exhibition booths, and architectural lighting. Their ability to create uniform brightness in a slim profile makes them essential for both commercial and residential lighting applications.

An LED sheet is a panel embedded with LEDs on its surface, directly providing illumination. An LGP sheet, on the other hand, requires external LED strips mounted along its edges. While LED sheets may provide faster installation, LGP sheets offer superior brightness uniformity and are often more cost-effective for large displays.

Use a soft microfiber cloth and mild soap solution to clean LGP sheets. Avoid strong solvents like acetone or thinner, as they can damage the surface. To maintain brightness, keep the sheet dust-free and avoid scratches. For premium applications, consider anti-scratch coatings or protective films during handling.

Yellowing usually occurs due to low-grade PS material or exposure to UV light and heat. Premium PMMA acrylic sheets resist yellowing much better. To prevent this, choose high-quality sheets, use proper LED drivers to reduce heat, and ensure protective coatings or films are applied in outdoor applications.

Yes, many hobbyists use LGP sheets for DIY LED lamps, wall art, and custom light panels. However, achieving professional results requires proper LED placement, edge polishing, and diffuser layering. If you are new, it’s best to buy pre-cut sheets or consult suppliers who can customize according to your project.

Several factors influence cost, including material type (acrylic vs PS), thickness, dotting technology (laser vs V-cut), brand, and country of origin. Imported acrylic LGP sheets are generally more expensive due to higher optical clarity. Large orders often reduce per-sheet cost, especially when buying directly from manufacturers.

Anand Plastics offers imported acrylic LED LGP sheets at competitive prices starting from ₹1,600/sheet onwards. With a clear MOQ of 10 sheets, standard sizes (8×4 ft), and multiple thickness options, they cater to wholesalers, fabricators, and signage companies. Their commitment to quality and customization makes them a trusted name in the Delhi LGP market.
