- Overview

   Visual tester is an equipment that tests

   the abnormality of the panel by authorizing AC, DC,

   and Video signals instead of operating IC(LSI)

   of operating IC(LSI) of OLED and small sized

   TFT-LCD panel that is produced in A-SI, P-SI(LTPS)

   type and it is a high precision tester that supports

   up to SOG 1 to SOG 4 levels.

- Usage

   The visual tester(P2) is used in the final test

   of the companies's all panel process that produces

   TFT and OLED panels.

- Features

   P2 tester is a tester that currently supports up to

   SOG 1~SOG 4 level and since it needs to conduct

   complicated operating IC's functions as a tester,

   the product has the following features.

   - AC PORT(30 channels) : -20V ~ + 40V

     (0.1V precision/100ns variable)

   - DC PORT(6 channels) : -20V ~ + 40V

     (0.1V precision/100ns variable)

   - VIDEO PORT(24 channels) : -15V ~ +15V

     (0.1V precision/100ns variable)

   - GND PORT(2 channels)

   - The H/W has a high-speed image processing

     technology at FPGA, an analog technology

     that converts voltage by PORT to high speed

     signals and a PC UI technology where users

     can manually or automatically call each signal

     image and convert the image

   - FPGA uses Vertex 4 level of Xilinx that has high

     speed large memory volume and for voltage voltage

     variable and variable speed, it realizes a precision

     voltage by using 100MBps level a/d and d/a.

  - For PC UI, the product uses USB and LAN enabling

     various types of data downloads such as model

     operating materials speedily and is developed

     to enhance users' convenience
