Front Light LED Backlight Modules

For medical equipment that requires silent, low‑glare illumination, our COG dot matrix LCD modules combined with a custom Front Light LED Backlight Module are the ideal solution. The front light sits above the display, eliminating the risk of backlight bleed and providing a soft, even light that doesn't disturb patients. As a full manufacturer, we also offer circuit board design and embedded program development – including light intensity control via PWM.
Bolong LCD's first division produces high‑reliability pen‑segment black and white LCD screens for the energy sector. By combining our LCD with our custom Front Light LED Backlight Module (manufactured in‑house), we deliver a complete display solution that works perfectly in dim control rooms or bright sunlight. You no longer need to source backlights separately – we integrate everything at the factory.

COG construction – Ultra‑thin <2.5mm total module thickness.
Custom dot matrix resolution – 128×64, 192×64, 240×128, or fully custom.
Embedded program development – We provide driver code, font libraries, and auto‑dimming based on ambient light.
Custom pen‑segment layout – Any icon, digit, or annotation for your specific meter.
Integrated Front Light LED Backlight Module – Uniform illumination without washing out contrast .
Reflective/transflective polarizer – Excellent sunlight readability; front light activates only in low light.
Ultra‑low power – Total module consumption <5mW LCD + front light on dim setting.
Wide temperature -30°C ~ +80°C for outdoor energy storage inverter meters.
Long life – >10 years for LCD, >50,000 hours for front light LEDs.

In‑house front light design – We can create ultra‑thin light guides for reflective TFTs.
Full PCBA service – Driver board with ambient light sensor circuit.
Embedded firmware – Auto‑dimming algorithm, touch calibration, OSD menu.
Optical bonding – We bond front light to TFT to eliminate air gap and improve durability.
Direct factory support – Work with our engineers to optimize sunlight readability.
Long‑term availability – 5+ year lifecycle guarantee for medical customers.
