Flexible display has many advantages including lower power consumption, lighter weight, and thinness. Therefore, several companies strive to develop new applications for flexible displays to keep abreast of market opportunities. Flexible displays depend on the reflection of module processes; thus, its bistability should be improved to obtain a good vitality of optical whiteness characteristic. The current study applies an integrated approach to find the optimal settings of important control factors to determine effectively the settings of various different design parameters, thereby meeting closely the bistability targets. An actual case study is used to demonstrate the usefulness of the suggested approach for improving the bistability characteristic of flexible displays. The optical whiteness ratio has been improved from 20.79 to 28.24. Also, the case company shortened the improvement schedule effectively, regained customer orders, and earned revenues of approximately USD 32,000,000.
