Mobile folding screen film UTG folding fatigue testerThe core is to use a dedicated machine to simulate the repetitive folding and bending movements in daily life.

During testing, the strip-shaped material sample will be fixed on the machine, and the machine will repeatedly fold it thousands of times according to the set angle, speed, and force. Researchers will continue to observe and record until the material experiences phenomena such as cracking, fracture, or decreased conductivity, in order to determine how resistant the material is to bending and how it will ultimately fail.

Simply put, it meansIn the laboratory, using scientific and controllable methods to quickly age and deteriorate materialsTo predict its lifespan and reliability in real use.

As a core component in the field of consumer electronics, foldable screens need to go through the process of daily useRepeatedly opening and closing thousands or even hundreds of thousands of timesThe structural reliability, material durability, and circuit stability directly determine the product's lifespan and user experience, therefore strict folding and dynamic bending tests must be conducted.

Folding test/dynamic bending test canHighly simulate real user usage scenariosContinuously conduct cyclic fatigue verification on the screen body, UTG ultra-thin glass, flexible display layer, FPC circuit, adhesive layer, and support structure under controllable bending radius, bending speed, and bending angle, exposing potential failure risks such as material cracking, delamination, creases, display abnormalities, touch failure, circuit breakage, or resistance drift in advance. Such defects are difficult to detect at room temperature and static conditions, and can only be effectively identified through dynamic fatigue testing.

Through the folding test of the system, it can be verifiedUTG cover plate, PI substrate, OCA adhesive, flexible OLED, conductive circuitThe tolerance of key materials and structures under long-term cyclic stress provides real and reliable data support for material selection, structural design, and process optimization. At the same time, foldable screens are high-value components. Once they are mass-produced and encounter problems such as screen body damage and display failure, it will bring huge after-sales costs and brand reputation losses. However, dynamic bending tests in the laboratory stage can significantly reduce such risks from the source.
