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.

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.
