LED Backlight Modules
Custom and standard LED backlight units from 200 to 2,000 nits — engineered for character LCD, graphic LCD, and custom display panel applications.
Product Overview
The LED backlight is a critical component of any transmissive or transflective LCD module — determining brightness, color temperature, power consumption, and operational lifetime. Relialink manufactures LED backlight modules as standalone components and as integrated parts of our display module assemblies, giving OEM customers the flexibility to source just the backlight, the panel, or a complete integrated module.
Our backlight designs cover edge-lit configurations (most common for thin profile requirements) and direct-lit configurations (for larger panels or high-brightness applications). Light guide plate (LGP) design, diffuser selection, and LED current optimization are all handled by our optical engineering team to ensure uniform luminance distribution across the active display area.
Available brightness ranges from 200 nits (standard indoor), through 500-800 nits (industrial and semi-outdoor), to 1,000-2,000 nits (outdoor and high-ambient applications). Standard white backlights and custom color options (blue, yellow-green, amber, RGB) are available.
All LED backlight modules are RoHS compliant. Rated lifetime is 50,000-100,000 hours at rated current and 25°C ambient.
Key Features
Edge-Lit and Direct-Lit Configurations
Edge-lit for thin profile requirements; direct-lit for larger panels and high-brightness applications.
Wide Brightness Range
200 nits (indoor) to 2,000 nits (outdoor) — one source for all your backlight brightness requirements.
Multiple LED Colors
White (various CCT), blue, yellow-green, amber, and RGB — with custom color matching available.
PWM and Analog Dimming
Flexible brightness control via PWM or analog current adjustment for precise luminance tuning.
Customizable Dimensions
Custom sizes compatible with standard and custom LCD panels — design flexibility for any project.
Long Operational Life
Rated 50,000-100,000 hours lifetime (T50 at 25°C) for reliable long-term operation.
