4. Application Scenario
The LS215I03-L-V1 is dedicated for Monitor products. Its 21.5-inch diagonal size with Full-HD (1920×1080) resolution, very high contrast ratio (3000:1 Typ.), ultra wide viewing angle (89° in all directions), and fast response time (6.5ms) make it an ideal choice for standard and professional desktop monitors, all-in-one PCs, and other display applications requiring high image quality and consistent viewing characteristics.
5. 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 (LS215I03-L-V1 Product Specification Revision 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 (CSOT open cell comply with RoHS for identification).
