1. Executive Summary And Product Positioning
The LS014I02-MP-V1 is a 1.4-inch diagonal transmissive type a-Si TFT-LCD (amorphous silicon thin film transistor liquid crystal display) module, manufactured by Lesson (Wanan) Smart Display Technology Co., Ltd. This comprehensive module integrates a TFT-LCD panel, a driver circuit, and a backlight unit (B/L) into a single package. The product specification (Revision 1.0, released on 2026-06-02) serves as the definitive technical document for this module.
This module features a resolution of 320(RGB)×320 pixels and is capable of displaying up to 16.7M colors. The module uses a MIPI interface and is driven by the ST77916 driver IC.
2. Detailed Product Overview And Architecture
The LS014I02-MP-V1 is a 1.4-inch TFT display. Its architecture is built around several key elements:
- Core Technology: Transmissive type a-Si TFT-LCD. The document specifies it supports IPS display mode.
