HXD-GK0885 is a high-specification DC backlight driver board that provides constant current; it is widely used for 55- to 100-inch LCD panel displays in systems featuring LED backlight modules.
HXD-GK0885 is a high-performance DC-DC LED backlight driver board designed to supply constant current to ultra-large, high-brightness industrial-grade displays. Utilizing advanced DC constant-current technology, it delivers an exceptionally stable current output suitable for high-power LCD panels. This universal backlight driver board operates on a standard 24V DC input and integrates seamlessly with industrial motherboards via a standard 14-pin/12-pin interface, enabling precise control of the backlight status by the system's main controller. With its robust driving capability, the LED driver board is specifically engineered for ultra-large LED-backlit displays ranging from 55 to 100 inches. It serves as a critical core component for large-scale LCD advertising displays, LCD televisions, large industrial monitors, high-brightness outdoor commercial displays, and systems designed for integration into demanding environments.
a. High Performance and Low Power Consumption:
This driver board achieves a conversion efficiency of up to 93.5% at a 24V input. Its low heat generation significantly reduces the thermal management design costs for the entire display assembly, extends the lifespan of peripheral components, and eliminates failures caused by overheating.
b. Dual High-Current Outputs, Adaptive and Adjustable:
This driver board features two independent constant-current outputs on-board, with an output voltage range of 80V to 220V. The total output current can be precisely matched by adjusting the shunt resistor according to your backlight parameters, allowing a single board to support multiple types of LCD displays.
c. Seamless Multi-Board Synchronization Interface (CN4):
Driving extra-large display devices often requires multiple constant-current boards operating in parallel. This backlight driver board features a dedicated CN4 synchronization interface (including Sync ADJ, Sync N/F, GND, and +24V parallel pins), making multi-board coordination extremely simple and ensuring absolute brightness consistency across all areas of the large display.
d. Dual Intelligent Dimming System (Light Sensing + Temperature Control Extension):
♦ CN3 Light Sensing Interface: Supports connection to a light-sensing diode to automatically adjust the screen’s brightness based on ambient outdoor light (0V for brightest – 5V for dimmest), achieving intelligent, low-carbon energy savings.
♦ CN13 Temperature Control Interface: Supports connection to a thermistor to monitor the display’s temperature and intelligently adjust output when temperatures are too high, preventing thermal degradation of the LED strips.
e. Comprehensive Industrial-Grade Safety Protection:
Built-in input overcurrent protection (fuse protection). In the event of abnormal voltage surges or downstream short circuits, the fuse will instantly cut off the power supply to prevent damage, safeguarding your expensive LCD panels and main power supply from being burned out.

Q1: Can you offer more competitive wholesale prices for bulk orders of the HXD-GK0885 backlight driver board?
A1: We fully support large-volume industrial procurement. We will provide highly competitive tiered wholesale pricing based on your project’s order volume (Bulk Orders). Please feel free to contact our online customer service or leave your email address to receive today’s latest mass production quote.
Q2: Do you provide samples? What is the fastest shipping time?
A2: Full support for sample testing: We fully understand the need to ensure that the backlight parameters perfectly match your LCD panel before mass production. We provide comprehensive sample support and detailed sample test reports. Express shipping: Standard samples are packed and shipped directly from our warehouse within 24–48 hours after order confirmation.
Q3: Can this backlight driver board be customized?
A3: Yes! The board itself supports adjusting the feedback resistor to change the total output current, allowing it to adapt to backlight modules from different manufacturers. One-Stop Customization Solution: If you have non-standard voltage or current requirements, special temperature control needs, or specific connector requirements, our R&D team can provide comprehensive circuit and functional customization based on your equipment’s operating environment, dimensions, and parameter standards.
Q4: What is the quality assurance for the HXD-GK0885?
A4: Every backlight driver board we sell undergoes extended full-load aging tests in a rigorous 60°C ± 5°C environment before leaving the factory, and passes a 0°C cold start test, withstand voltage testing, and visual inspection. We provide a 1-year standard manufacturer’s warranty. During this period, our team of senior electronics engineers will provide round-the-clock technical support and remote assistance for any technical questions you encounter during installation and screen debugging.
Q5: How do you ensure its safety during international shipping?
A5: Professional anti-static and shock-absorbing protection: Since backlight driver boards are bare boards without enclosures, we strictly implement anti-static protection measures. Throughout the entire delivery process, each board is individually packaged in an ESD-shielded bag and sealed in a reinforced cardboard box to ensure that no physical impact or electrostatic discharge occurs during transit.
