We provide a broad range of TFT testers, also known as a digital video generator or flat panel display tester, for display modules and display panels ranging from small format cell phone displays to large TFT panels for LCD TV. Our testers give you control over video timing, power levels, image content, and in most cases, inverter controls for backlighting.
 

Our T-Drive™ family of products feature PC-based software to allow the test engineer to set up all the required profiles (see side bar) and images within a unit. The test technician can then perform easy-to-learn operations from a handheld keypad, making the T-Drive™ a truly easy-to-use tester for multiple display part numbers!

T-Drive™ products provide fast, flexible image changes. The user has two choices for image content: built-in images or downloaded bitmap files (see side bar), providing the ultimate flexibility for required test images.

• Our T-Drive™ Model I  is a TFT tester, (or TFT driver) ideal for the TFT repair industries and for automated measurement systems. This TFT driver has been a market leader for over three years!
• Our T-Drive™ Model II is a TFT similar to a Model I, but with enhanced power and a 10 bit LVDS output
• Our T-Drive™ SD100 is the industry's first universal tester to drive most small format displays on the market today, from RGB interfaces to CPU interfaces to SPI serial interfaces! The unit includes accurate LED drive. The SD100 is used primarily as a cell display drive unit.
• Our T-Soak™ provides (4) identical outputs simultaneously. This is ideal for burn-in testing as well as comparative analysis of panels.
  Built-in images and Bitmap images: T-Drive™ includes built-in images that are common for test purposes.  These images are created based on the resolution of the currently selected image.  Thus, built-in images support all possible resolutions.  In most cases, the intensity of the image is selectable via the keypad, providing nearly infinite amount of image selections!  For example,
  T-Drive™ Model I supports 8 bits per color.  Therefore, any full screen color is selectable from the keypad, providing 16 millions colors!  These images are created real-time inside T-Drive™, and require no internal storage.  For complex test patterns, the user can download test pattern bitmap files  into the non-volatile storage within the T-Drive™, providing dozens of additional test patterns!

Other Universal Tester products and services include:

• Tooling Solutions to support the test of your display on our products. Tooling usually includes a file to configure the tester, as well as an interconnect solution.
