Mobile LCD Tester - T-Drive SD100

T-Drive SD100
Mobile Display Tester

Our T-Drive SD100 mobile display tester can drive most small format displays on the market today such as cell phone display modules and tablet displays. The T-Drive SD100 is a popular flat panel display tester for LCD displays and C-STN displays with CPU or SPI interfaces used extensively in product development R&D and manufacturing QA/QC.

T-Drive SD100 provides everything you need to drive your cell phone or tablet display including the video interface (RGB or CPU), power, discretes, constant-current LED sources, and SPI programming interface. 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 panel. If you need a custom test pattern, T-Drive SD100′s bitmap capability is a feature you will appreciate.



Supports RGB, CPU and SPI Interfaces

Programmable horizontal and vertical timing for RGB interfaces. Selectable CPU or SPI interface types, with programmable bit-packing and sequences to initialize the display


Powerful test pattern capabilities

Wide selection of built-in test patterns or downloaded images, quickly loaded to the display via the RGB interface or the appropriate CPU or SPI graphic memory interface


Programmable power rails

3 programmable power rails for your small format display and accurate drive currents for various LED backlight configurations, including LEDs connected in series or in parallel

Powerful Configuration Utility

T-Encoder helps you to manage the timing profiles and pattern lists stored in your T-Drive SD100. T-Encoder includes an easy to use editor to create timing/electrical module profiles and pattern lists. Timing profiles and pattern lists are easily downloaded to the T-Drive SD100 via USB. Some of the parameters that can be configured using T-Encoder include:

  • Programmable raster timing and programmable power
  • Custom pattern download and display
  • Backlight driver control
  • User-defined pattern lists and auto pattern sequencing

Hardware Configurability

The system comes standard with digital interface, power/LED drive cards and bitmap capability. Other options are available such as display interconnect kits, TMDS / Analog RGB output card, LVDS output card, and Windows DLL for remote control.

Enhanced Pattern Generation

T-Drive SD100 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 SD100 for display on your LCD.
