LS050I41-MP-V1 4.96 inch TFT-LCD Module 480x854 16.7M Colors

1. Executive Summary & Product Positioning

The LS050I41-MP-V1 is a 4.96-inch transmissive type a-Si TFT-LCD (amorphous silicon thin film transistor liquid crystal display) module developed by 立信（万安）智显科技有限公司 (Lesson Smart Display Technology Co., Ltd). The panel size is 4.96 inch and the resolution is 480(RGB)*854, the panel can display up to 16.7M colors. This module is a COG (Chip-on-Glass) + FPC + B/L (Backlight) construction. The product specification was first released on 2026-09-10.

Product Positioning: This 4.96-inch module is well-suited for a wide range of applications requiring a compact, high-quality display with a full viewing angle. It is ideal for handheld devices, portable instruments, smart home controllers, wearable electronics, and other embedded display systems requiring MIPI DSI interface.

2. Detailed Product Overview & Architecture

The module's architecture is designed for robust performance and easy integration. The primary components include:

• TFT-LCD Panel: 4.96-inch diagonal, a-Si TFT active matrix, transmissive, IPS (In-Plane Switching) with free viewing direction (gray inversion). Resolution is 480(RGB) × 854 pixels.
• Driver Circuit: The module integrates the ST7102 driver IC, communicating via a MIPI DSI 2-Lane interface.
• Backlight Unit (B/L): A white LED backlight with 12 Chip-White LEDs configured in 4S3P (4 series × 3 parallel). The typical driving condition is Vf=8.4V~9.3V, If=80mA (4×20mA).
• Mechanical Construction: COG (Chip-on-Glass) + FPC + B/L. The LCM outer dimension is 64.08(W) × 115.76(H) × 2.31(D) mm.
• Interface: The module communicates via a 16-pin FPC connector. The display interface is MIPI DSI 2-Lane.
• Display Mode: Transmissive, IPS.
• Viewing Direction: Free viewing angle (IPS).
• RoHS: All materials are compliant with RoHS standards.
