Introduction
This document is the official product specification for the LS020I12-S-V1, a 2.01-inch transmissive a-Si TFT-LCD module developed by LESSON Smart Display Technology Co., Ltd. Featuring a resolution of 240(RGB)×296, 262 thousand colors, and a module type of COG+FPC+B/L+LENS, this indicates a Chip-On-Glass (COG) construction with a Flexible Printed Circuit (FPC), Backlight (B/L), and a protective LENS. It is designed for applications requiring a very compact, rectangular display with a protective cover lens, such as wearable devices, small handheld instruments, IoT device interfaces, and compact consumer electronics.

General Description
The LS020I12-S-V1 is a highly integrated, ultra-compact display module. The COG construction minimizes the footprint, while the inclusion of a LENS (cover glass) provides protection for the LCD surface. The non-square resolution of 240×296 gives it a slightly taller aspect ratio than a standard square, which can be advantageous for displaying lists or status information. The specification includes detailed mechanical drawings with critical dimensions, backlight drive conditions, and a pin assignment table (接口定义), indicating a comprehensive design document for mechanical and electrical integration.

Key Features

  • Ultra-Compact Size: 2.01-inch diagonal with COG construction.
  • Integrated Protective Lens (LENS): Ready for front assembly.
  • Specific Driver IC: Uses the NV3030B-02 controller.
  • Detailed Mechanical Drawings: With critical dimensions and tolerances.
  • Clear Backlight Specification: 4-LED, 80mA drive.
  • Full Pinout Definition: For easy interface connection.

Application Scenarios

  • Wearable Devices: Smart bands, compact smartwatches.
  • Portable Medical/Industrial Instruments: Small readout screens.
  • IoT Device Dashboards: For smart home controllers, etc.
  • Consumer Electronics Accessories: As a secondary display.

Conclusion
The LESSON LS020I12-S-V1 is a specialized, small-format display module that combines a protective lens and COG technology into a ready-to-integrate package. It is an excellent choice for space-constrained designs where a durable, compact color display is needed.
