Electrophoretic displays (EPDs) are known for near-Lambertian reflection characteristics, resulting as paper-like appearance. This also means that EPDs can be front-lit with shallow light incidence. This suits well for 2-sided optical bonding of the front lightguide plate (FLGP) in the display module stack. Nanocomp´s unique microstructured FLGP stands out from the competition with it´s excellent contrast and color properties. Nanocomp provides the following FLGP solutions: - FLGP for B/W EPD - FLGP for advanced color EPD - FLGP for color filter EPD
Our continuous lightguide film, NCLux Film, is an example of a cutting-edge technology introduced into the automotive marketplace. Most of the features our NCLux Film provides differentiate significantly from our competitors, that is also how we excel in this arena. The thickness of our lightguide film being as thin as 0,5mm or less is extraordinary, particularly for the designers. It renders more space and freedom for designing as well as facilitating the lamination of a variety of topcoats, such as perforated wood, plastic, metal, leather and fabrics. Meanwhile, the flexibility of the film makes it possible to apply our lightguide to the most moderately curved surfaces. The continuous lightguide film is supplied in rolls, thus the length of applications is unrestricted. What’s more, our embedded micro-optics are rarely seen, if not being the only provider in the industry. Not only are they highly efficient but also have a remarkable score of over 80% in luminance uniformity.

The 9.7” FLGP for EPD carries on the same merits possessed by the product family, particularly, high contrast ratio, low power consumption and exceptional thinness. The thickness of this 9.7” FLGP is 0.4 mm. It can be operated effectively with as few as eight pieces of LEDs, making it a good fit with applications requiring low power consumption. Certainly, more LEDs could be added to further improve luminance level if desired. By applying another set of warmer LEDs, the adjustment between the cool/warm color temperatures can be realized, providing extra eye comfort for different reading situations. Technical data of this product is displayed below. Key performance measures: - Uniformity ≥85% (VESA, 9 points) - Δu´v´<0.008 (CIE 1976, 9 points) - Efficiency: 300 cd/m2@1 W - Material: PC Identical to other models of our FLG products, the 9.7” FLGP is an excellent choice for e-reading and information display applications alike.
