| To fully qualify a flexible display device or an FPC board, engineers rely on sophisticated bending test machines to execute a variety of mechanical stress profiles. The most prevalent and highly scrutinized method is the 0° to 90° reciprocating bending test. | Core Testing Methodologies: Bending, Folding, and Flexing |
| In this rigorous protocol, one end of the flexible specimen is securely clamped to a stationary fixture, while the other end is attached to a rotating pivot point. The equipment then drives the specimen through a continuous, sweeping motion from a flat 0° baseline to a 90° flexed position, and back again. | The 0 to 90 Degree Bending Test Equipment Protocol |
| What makes this test uniquely challenging is the requirement for dynamic precision. A high-quality 0 to 90 degree bending test equipment must execute this motion without introducing mechanical inertia or unintended vibrations, which could cause premature micro-cracking in the display’s conductive layers. | |
| By continuously monitoring the electrical resistance or optical integrity of the sample during these cycles, manufacturers can pinpoint the exact moment of material fatigue failure. |
The International Electrotechnical Commission (IEC) established the IEC 62715-6-1 standard to define the mechanical stress test methods specifically for flexible display devices, including OLEDs, e-paper, and flexible printed circuits (FPC). Tracing its evolution from the earlier BS IEC 62715-6-1:2014 to the comprehensively revised IEC 62715-6-1:2018 edition, the standard has continually adapted to the increasing complexity of modern flexible modules.
Key Evolutions from 2014 to 2018 Editions: While the fundamental physics of bending and folding remain constant, the 2018 revision introduced more granular methodologies to address the multi-layered architecture of contemporary flexible screens. The updated standard explicitly details environmental conditioning, specific bending radii (R-angles), and precise tension requirements during the folding process. It demands that an IEC 62715-6-1 folding test machine not only performs repetitive motions but also maintains absolute geometric consistency to prevent unnatural shearing forces from skewing the test results.
