Introduction
Project Introduction

Manufacturing TFT-LCD (thin film transistor liquid crystal display) panels is a complicated and highly technical process. The three major stages in TFT-LCD panel production are the array, LC cell, and module assembly processes. In addition, each finished panel must also pass a series of quality inspection tests such as defect inspection and lighting tests.

The most challenging part of the TFT-LCD manufacturing process is achieving zero fault tolerance for high quality and productivity. One of our customers needed a USB-to-serial solution to transmit data between a host and quality inspection equipment in the TFT-LCD manufacturing process. In such a demanding manufacturing environment, adopting multiple ports and a ruggedly designed USB-to-serial product proved to be the best option.

Application Requirements

1. Industrial-grade design for the TFT-LCD manufacturing process
2. High quality solution for complicated high-speed data transmission to improve operational efficiency
3. Support for multiple USB-to-serial expansion ports
