TFT Defect Inspection in LCD Panel Assembly

Flat Panel Display Production

Taiwan

Introduction

During the LCD manufacturing process, having a zero fault tolerance is almost impossible.

Moreover, LCD panels are very delicate products, and can frequently have minor defects.

Therefore, defect inspection is essential at each assembly station. Our customer wanted

to increase the efficiency of their defect inspection stations and speed up their overall LCD

production. They were using the traditional method of inspection, which consisted of having just

one camera to complete the process, which is slow and cumbersome. With a new PC-based

automation solution from Advantech, more cameras can be set up for inspections, allowing a

smoother and faster production flow.

Project Requirements

Defect inspection is an extremely important part of

the production process. It prevents a vicious cycle

by not allowing defects to continue further along the

manufacturing process. With the implementation of

more than one camera, increased processing speed

and network expansion are necessary. In order to

efficiently inspect each large LCD panel, using a

PC-based operating system is the optimal way.

Furthermore, it allows data communication between

the database and each station. To formulate such

a system, we need the following components to

complete our automated solution:

•

A master control card for handling all the

commands and data flow

•

A motion control card for all the camera

orientations

•

An isolated Digital I/O card for the command

and handshakes between stations
