LM215WF3-SLC1 Backlight Unit
The LM215WF3-SLC1 features a side-lit WLED (White LED) backlight that requires a dedicated LED driver board to provide stable DC power. The backlight typically uses multiple LED strings, with a driving voltage of around 30–45 V, depending on the circuit design.
WLEDs require constant-current driving rather than direct constant-voltage power. The typical operating current is around 120–240 mA. The driver should provide accurate current regulation, overvoltage and overcurrent protection, and support PWM or analog dimming for smooth brightness control from 0% to 100% and longer backlight life.
LM215WF3-SLC1 Key Features
The LM215WF3-SLC1 offers several key features for high-quality display applications, meeting a wide range of display requirements. The main advantages are as follows:
l Provides a spacious 21.5’’ diagonal viewing area for various display applications.
l Delivers a 1920 × 1080 resolution for clear and detailed images.
l An integrated white LED backlight for consistent screen illumination.
l Provides high color saturation and supports more than 16.7 million colors with A-FRC.
l Uses an 8-bit, 2-port LVDS interface for high-speed display data transmission.
l Provides a dark screen state when no image signal is applied, improving perceived contrast.
l Uses a matte display surface to help reduce reflections and glare.
l Operates from 0℃ to 50℃, with a storage temperature range of -20℃ to 60℃.
LM215WF3-SLC1 Functional Block Diagram
The 30-pin CN1 connector carries 2-channel LVDS signals and a +5.0 V power supply. After power conversion, the supply powers the TCON, Source Driver, and panel. The TCON converts LVDS signals into RGB data and generates control signals for the Source Driver (S1–S1920) and Gate Driver (G1–G1080), driving the 1920 × 1080 pixel array.
The backlight uses a separate 6-pin CN2 connector for VLED power, which directly drives the WLED backlight.
LM215WF3-SLC1 Driver Board & Controller Compatibility
To power and display the LM215WF3-SLC1, a universal HDMI/DVI/VGA-to-LVDS controller board is required. The board should provide 5V logic power (VCC) and a separate 6-pin backlight connector or compatible constant-current LED driver to support the WLED backlight and dimming.
Proper matching of the LVDS cable and firmware is essential. The cable should be a 30-pin, dual-channel 8-bit LVDS cable with the pinout matching the CN1 connector exactly. The controller board should also be programmed with firmware for 1920 × 1080 resolution and 2-channel 8-bit LVDS (2ch 8-bit) to ensure stable image output without distortion or shifting.
LM215WF3-SLC1 Interface & Pinout Definition
The LM215WF3-SLC1 uses a 30-pin CN1 connector for 2-channel 8-bit LVDS display signals and +5V power. A separate 6-pin CN2 connector is used for the WLED backlight power. The CN1 pins mainly include power, GND, LVDS data, and differential clock signals, and must be connected according to the defined pinout to ensure proper data transmission and stable panel operation.

Operating Conditions
1) Spike noise should be kept below ±200 mV (overshoot/undershoot) to prevent circuit malfunction.
2) Response time varies with temperature and becomes longer at lower temperatures.
3) Brightness decreases at lower temperatures, while the time required for brightness to stabilize increases.
4) Avoid condensation caused by sudden temperature changes, as it may damage the polarizer or electrical contacts and cause smears or spots.
5) Displaying fixed patterns for extended periods may cause image retention.
6) The module contains high-frequency circuits. Proper grounding, shielding, and EMI suppression are required to minimize interference.
7) Avoid mechanical or acoustic shock, which may affect the module's performance.
8) Use machine screws when fastening the module to metal parts to prevent metallic debris and damage.
9) Do not place or store the LCD on its edge.
10) Dirt (yogore) and image sticking are not guaranteed against.
