T6391 Display Driver Tester Expands Capabilities with New Per-pin Digitizer and Comparator (LCD HP)

Advantest announced its new LCD HP (high-performance) per-pin digitizer and comparator module. Developed for use with the T6391 display driver test system, the LCD HP module features two key performance improvements. First, it improves measurement precision 5x compared to the previous module, making it ideally suited to accommodate the testing demands of advanced display driver ICs (DDICs) for high-end smartphones and augmented/virtual reality (AR/VR) applications. Second, it can handle high-voltage testing up to ±40V, enabling the module to address the high-reliability testing demands of brand-new automotive DDICs.

“This is an exciting time for the display market and, by extension, for the test industry,” said Toshiaki Adachi, senior vice president, Advantest SoC Test Business Unit. “As the market for metaverse devices grows, adoption of OLED display panels is expected to escalate, while the shift to EVs calls for automotive displays that centralize cockpit clusters, infotainment and other display functions. All of this technology development is placing new, more stringent requirements on test and measurement. Our T6391 tester and new LCD HP module will lead the way in addressing these demands.”

The LCD HP module achieves noise reduction and uniform measurement accuracy between channels in the test system to enable high-precision measurement. It covers test requirements of new advanced DDICs for high-end smartphone and AR/VR applications, enabling the tester to support high-gradation testing with measurement accuracy of ±200μV. In addition, by supporting high-voltage testing up to ±40V with certain loads, the module enables functional testing of automotive DDICs that reflect their actual operations.

The T6391 LCD HP module is highly compatible with existing modules, enabling fast, easy integration with the customer’s test setup.
