General Description
The LSL215I01-L-V1 is a professional-grade, large-format LCD module. It uses a VA panel which offers high contrast ratios and wide viewing angles. The module accepts a standard dual-channel LVDS signal (compatible with FI-X30HL connector). The specification is exceptionally detailed, covering not just basic specs but also absolute maximum ratings for environment and voltage, recommended operating conditions, pin assignments (32-pin connector), input signal timing (supports 60Hz & 75Hz), power sequence timing, and extensive reliability test conditions.
Interface & Key Features
- Connector: 32-pin, dual-channel LVDS (P-TWO AL230F-A0G1D-P or STM MSCKT2407P30HB).
- Input Timing: Supports frame rates from 50Hz to 76Hz, clock frequencies from 54.8MHz to 90.0MHz.
- Power Sequence: Strict timing (T1-T7) defined between VDD, LVDS signals, and backlight to prevent damage.
- High Contrast: 3000:1 typical contrast ratio.
Application Scenarios
- Desktop PC Monitors: Office, home, and professional use.
- Industrial Monitors: Control room displays, factory automation HMIs.
- Medical Displays: Patient monitoring, diagnostic review (subject to medical certification).
- Gaming & POS: Arcade machines, point-of-sale systems.
- General Purpose Display: Any application requiring a reliable 21.5" FHD panel.
Conclusion
The LESSON Smart Display LSL215I01-L-V1 is a comprehensively specified, industrial-grade display module.
