Nanocomp front light for EPD

The most important property of the B/W EPD is the contrast ratio (CR). From a front lighting (F/L) point of view, the most important aspect is the ability of the system to maintain the CR when the F/L is switched on. This has a lot to do with the light extracting microstructures, their shape and replication accuracy. Any upward scattering light introduced by the frontlight operation will cause haze and decrease the CR. Nanocomp front light, with optimally engineered and perfectly replicated microstructures, offers superior CR levels for the frontlit display. - Most consumer products built on color EPDs are implemented with color filters to allow for the most versatile content and various media to be accessed with these devices. Since the filters are of a certain physical distance above the actual ink pixels, there can be leakage of incident light from one pixel to a neighboring one, which causes colors to mix and thus reduce in purity. This means a narrowed color gamut. To compensate for that, the incident light used to illuminate the display should be steep- and narrow angled. This can be implemented with Nanocomp frontlight, which indeed can enhance the color gamut of the display, if the F/L is kept operational whenever the display is in a state of dynamic use. - In addition to CR and color gamut, one more important aspect of Nanocomp technical excellence lies in the ability to control the color consistency (stable white balance) across the display area.

Microfluidics features

Our technology have been also applied for creating microfluidics features, such as microchannels and microwells on plastic. Both tooling and manufacturing can be done with in-house capabilities.

Microstructured Films

Microstructured films manufactured by UV roll-to-roll imprinting In addition to microlens arrays (MLA), other complex microstructures, such as fresnel lenses, microfluidics features and waveguide structures, are also manufactured with Nanocomp's modern manufacturing technologies. However, any similar microstructures can be customized according to your specifications. Key benefits of Nanocomp Microstructured films: - Ultra thin and flexible film components (down to 10µm total thickness) - Excellent optical performance by precise structures - Customized arrangements and parameters

9.7" frontlight

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.
