LCD Tester - T-Drive II

T-Drive II

LCD Tester

Westar’s T-Drive™ II is ready to meet the needs of the LCD panels in today’s consumer electronics; with 10 bit color output, quad LVDS, eDP/DisplayPort, high pixel clock frequency, programmable power, and more. The T-Drive™ II LCD tester can drive LCD panels for LCD-TV, Notebook PC’s, and monitors.

T-Drive™ II provides a complete stimulus for LCD panels and monitors sized to fit on your workstation. The easy-to-use keypad, built-in pattern sequences, and storage for hundreds of drive profiles allow an operator to test panels quickly and efficiently. Built-in test patterns, such as a movable crosshair, and easy adjustments, such as color intensity and backlight intensity, help the operator quickly assess a LCD panel.

A standard T-Drive™ II is delivered with Quad LVDS output and the ability to display downloaded bitmaps.

Applications

LCD Tester for notebook, monitor, and TV repair

Digital video generator for automated LCD optical testing

LCD Tester for flat panel display R&D and QA/QC

Video & trigger stimulus for latency measurements

Powerful Configuration Utility

T-Link is a software application that helps you to manage the files stored on your T-Drive II. T-Link includes an easy to use editor to create a timing / electrical panel profile and pattern list.  Some of the parameters that can be configured using T-Link include:

  • Programmable raster timing and programmable power
  • EDID read/write/compare
  • Custom pattern download and display
  • Power consumption measurements
  • Backlight driver control
  • User-defined pattern lists and auto pattern sequencing

Hardware Configurability

T-Drive II has four video output card slots. This gives you the ability to populate the tester with the needed outputs. The standard tester comes with one Quad LVDS output card leaving three spare slots for optional cards such as DisplayPort, TMDS/Analog, or Digital parallel TTL outputs.

Enhanced Pattern Generation

T-Drive II includes enhanced patterns with adjustments for color, intensity, and, where applicable, position and size. Custom patterns in the form of bitmaps may be downloaded and stored in T-Drive II for display on your LCD.

Westar’s family of LCD Testers are supported by our Tooling Solutions. A tooling solution allows you, the customer, to use our LCD Tester to test a particular display. Tooling solutions are developed cost-effectively by our support staff, saving you time and money for your test functions.

For quickest delivery of tooling solutions, we ask that you supply a sample display, along with its specification or datasheet. Our tooling specialists will use this information to create a tooling solution. We have already developed hundreds of tooling solutions for many common LCD panels. Just ask our support staff if we have a solution already complete!

Our cabling solutions are delivered with schematics to allow you to repair your cables, or build more yourself. Our profiles are ready-to-use on your TFT Tester, already tested at our facility!
