3.2 System Block Diagram
The system integration involves a Timing Controller (LVDS Rx & Mini-LVDS Tx integrated) interacting with a Source Driver, a Power Circuit Block, and a GOA (Gate Driver on Array). The interface is connected via a 30-pin connector (CN1).
The key interface signals include:
- VDD: +5.0V Power Supply
- LVDS: 2 Ports LVDS Interface
4. Interface Connection (Pin Description)
The LS215I04-L-V1 uses a 30-pin connector (CN1). The pinout includes power supply (+5.0V), ground (GND), and 2-Port LVDS signals.
5. Application Scenario
The LS215I04-L-V1 is specifically designed for Process Controller Monitors. Its 21.5-inch diagonal size with Full-HD (1920×1080) resolution and high contrast ratio (3000:1) make it an ideal choice for industrial and process control display applications requiring clear and detailed visuals.
6. Handling Precautions And Compliance
The LCD panel is made of glass and is fragile. The polarizer surface is easily scratched. The module should be handled with care to avoid applying pressure on the display area. ESD (Electrostatic Discharge) protection is mandatory throughout handling and assembly. The module should be stored in a clean, dry environment away from direct sunlight and corrosive gases. It is strongly recommended to read the full specification document (LS215I04-L-V1 Specification Sheet Version 1.0) before integration and to test the module under application-specific conditions. The manufacturer disclaims liability for damages resulting from improper use or modification. The product is RoHS compliant.
