Flexible OLED Display Narrow Bezel via Substrate Bending

The patent resolves the contradiction by transitioning from a planar electrode binding approach to a three-dimensional folded structure. The flexible substrate is bent such that the electrode binding region extends along the folding line, utilizing the vertical dimension created by the fold angle (90-180 degrees) to accommodate the binding region without increasing the horizontal frame width. This dimensional change allows the display region to be enlarged while maintaining sufficient electrode binding area for reliable electrical connection.

The patent applies curvature by introducing a folding line that creates a bent or curved configuration in the flexible substrate. This curvature allows the electrode binding region to be distributed along the folded structure, enabling narrow frame dimensions while maintaining adequate binding area. The folded geometry effectively packs the binding region into a compact space that does not compromise electrical connection reliability.

The patent utilizes the inherent flexibility of the flexible substrate and thin film encapsulation layer to create the folded structure. By selecting materials that can be bent to angles of 90-180 degrees without cracking or delamination, the design achieves narrow frame dimensions through a relatively simple folding operation rather than complex mechanical assemblies. The thin film nature of the encapsulation layer allows it to conform to the folded geometry without adding significant structural complexity.
