3.3 Driver IC ESD Specifications
The Electro-Static Discharge tolerance of Source COF IC and Gate COF IC is ±2KV tested by ESD Gun. If the LCD module is designed with a Plastic Bezel, it is suggested that ESD protection solutions (such as Conductive tape connecting to Ground) should be applied to avoid damage.
4. Interface Connection (Pin Description)
The LS2145I01-L-V1 uses a specific interface connector (CN1: 1-301223-0 or equivalent). The interface pin assignment details a specific pinout including LVDS data pairs, clock pairs, power supply, and control signals. Please refer to the full specification document for the complete pin map.
5. Application Scenario
The LS2145I01-L-V1 is designed for a wide range of industrial and commercial display applications. Its 21.45-inch diagonal size with Full-HD (1920×1080) resolution makes it suitable for industrial monitors, medical equipment displays, POS systems, kiosks, and other embedded display systems requiring a reliable and high-resolution screen.
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 (LS2145I01-L-V1 Specification Sheet) before integration. The manufacturer disclaims liability for damages resulting from improper use or modification. The product is RoHS compliant.
