CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The primary function is to provide uniform illumination behind the liquid crystal layer of an LCD panel, making the display visible. Since LCDs do not emit light themselves, the backlight unit is essential for image visibility.
Common materials include polycarbonate, polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), LED chips, and aluminum. These are used for light guides, diffusers, and structural support.
Typical parameters include screen size from 7 to 65 inches, luminance from 300 to 1000 cd/m², uniformity of at least 80%, color gamut of 72-100% NTSC, operating temperature -20 to 70°C, storage temperature -30 to 80°C, input voltage 9-36 V DC, power consumption 5-50 W, thickness 1.0-10.0 mm, weight 0.1-5.0 kg, LED lifetime 30,000-50,000 hours, and viewing angle 70-89 degrees. These are reference ranges and must be confirmed for specific models.
You should consult the legal manufacturer or supplier to confirm model-specific values for parameters such as luminance, uniformity, and electrical specifications, as well as any applicable standards. The directory provides reference ranges only and does not certify compliance.
