Flexible & Embedded Display Challenges
What are the challenges of creating a nonconformal display?
Bending & handling induces tension and compression
Pressure alters film thickness and distorts image uniformity
Compression with handling induces buckling and permanent image loss
High temperature and pressure conditions during manufacturing process can damage film
