Comprehensive Technical Specification & Application Guide

1. Executive Summary & Product Positioning

The LSC0397I11-MP-V1, developed by LESSON (Wan'an) Zhixian Technology Co., Ltd., is a 3.97-inch transmissive amorphous Silicon TFT-LCD module with an integrated Capacitive Touch Panel (CTP). This product specification defines its structural composition (COG+FPC+B/L+CTP), physical features, mechanical size, absolute maximum ratings, electrical parameters, detailed MIPI DSI (Display Serial Interface) timing, and key electro-optical characteristics. It delivers a resolution of 480(RGB)×800 with 16.7M-color display capability. The document provides the complete technical basis for design and application. The recommendation is for engineers to strictly refer to these specifications for design and inspection, ensuring the module operates reliably within the defined power, temperature, and timing constraints.

4. Application Guidelines & Critical Notes

• Intended Use: Smartphones, feature phones, portable media players, industrial PDAs—applications requiring a medium-resolution, high-quality display with an integrated touch panel.
• Critical Design Considerations:
  1. MIPI DSI Host Required: This module requires a host processor with a MIPI DSI transmitter. It is not compatible with simple parallel or SPI interfaces.
  2. Dual Power Supplies: Provide clean VCC (2.8V typical) and IOVCC (1.8V typical).
  3. Signal Integrity: The MIPI differential pairs (D0P/N, D1P/N, CLKP/N) require controlled impedance on the host PCB.
  4. Reset Timing: Observe the minimum 10µs reset pulse width. Be mindful of the longer 120ms recovery time if resetting during normal operation.
  5. Unused Pins: Pins like TE and PWM should be left open when not in use to avoid interference.
  6. Robust Temperature Range: Designed for -20°C to +70°C operation, suitable for many industrial environments.
• Mechanical: The module includes an integrated CTP (Capacitive Touch Panel). The mechanical design must accommodate the thickness and dimensions of the entire assembly.

5. Conclusion & Design-In Support

The LSC0397I11-MP-V1 specification defines a 3.97-inch WVGA display module with a modern MIPI DSI interface and integrated touch. Its key features are the high-resolution 480x800 display, 16.7M color depth, and wide industrial temperature range. The detailed MIPI DSI timing parameters are crucial for establishing a reliable high-speed data link. Designers must ensure their host processor can support the MIPI DSI interface and provide the necessary dual voltage power rails.
