Fabrication and bending reliability evaluation of flexible electrowetting display device
View through CrossRef
AbstractThe Electrowetting Display (EWD) has numerous advantages making it a potential candidate for flexible displays. However, there has been limited research on the bending performance of Flexible Electrowetting Displays (FLEWD) and their feasibility in terms of flexibility has not been confirmed. To investigate the impact of bending on stability performance, FLEWD using flexible active‐matrix substrate and PEN conductive substrates were fabricated. A systematic performance evaluation system for flexible devices is established. The results showed that FLEWD can display videos normally during bending. In the off state, the device can withstand a bending limit represented by a radius of 2 cm at a bending speed of 80 mm/s for 5,000 times. In the on state, the corresponding limits are 4 cm, 40 mm/s, and 100 times. Besides, the failure mode of FLEWD bending is clarified, which provides a guideline for the improvement of the flexural performance of flexible EWD in the future.
