YUASA Systems demonstrated new solutions for flexible display testing at the Society for Information Display (SID) Display Week.
Building on its capabilities for repeated physical motions using unique tension-free technology that enables non-destructive performance evaluations, YUASA demonstrated three new capabilities at the Display Week Exhibitor’s Forum:
- A new optical analysis system (CS-CAM) that integrates an optics package and image processing software into a standard CS clamshell-type flexing mechanism. Using a side- view mounting configuration, the CS-CAM can provide real-time edge strain analysis for early delamination detection while testing multi-layer film stacks;
- A new test cartridge (CS-TD) for both the standard and twin mechanical jigs that enables “teardrop” shape flex testing, with adjustable parameters for neck width, tear length and width to simulate different sizes and shapes of hinges on display devices. Alternatively, this cartridge can adjust the neutral plane for multi-layer flexing;
-
A new medium size flexing jig (CS-M) suitable for testing tablet and laptop displays. As with all CS jigs, the CS-M provides clamshell-type flexing of linear or planar objects to a 0.5 mm radius and works with the ECP system control and data capture package.
In addition to these new products, YUASA Systems, working with its US partner Bayflex Solutions, is developing new capabilities in multi-environment chambers (PICO) that provide desktop endurance testing in multiple hostile conditions such as humidity, temperature, as well as data analysis capabilities that can provide real-time assessment and predictive analytics based on test data.
Finally, in order to adapt the “new normal” of work from home, YUASA Systems and Bayflex Solutions now offer equipment on a subscription basis in addition to purchase and have opened test centers in Japan and the U.S. so that clients can ship samples for testing.
“YUASA Systems is pleased to continue to offer the advanced testing capability to the display industry, for flexible displays, touch screens, and other flexible components. The development of the CS-CAM, CS-TD cartridge and CS-M products were in response to the requirements of display and touch screen materials suppliers, panel makers, and system integrators, all of whom need to have repeatable, controlled endurance testing simulating real-world physical conditions,” said Eisuke Tsuyuzaki, principal, Bayflex Solutions. “This year’s solutions are significant as we are eager to introduce a completely new series of optical imaging and enhanced data analysis capabilities.”
