17.1 - Cylindrical Fiber-Based Oxide TFTs with a 2T1C Pixel Circuit for Wearable Textile Displays (2:00 PM - 2:20 PM)

This study introduces a simplified fabrication method for implementing a TFT array on a cylindrical fiber, using only four masks and a low-temperature process below 120 degrees Celsius. To overcome the limitations of the one-dimensional cylindrical fiber structure, the study emphasizes the design and implementation of a three-dimensional backplane, utilizing the side or bottom surfaces of the fiber to address patterning and shadowing challenges. The proposed TFTs, part of the 2T1C pixel circuit within the fiber, exhibit electrical properties suitable for driving OLEDs.

The authors propose a standard 4-edge curved model for the first time, which contains a standard geometric model based on superelliptic curves and a mapping relationship from a plane to a three-dimensional surface. In this model, they quantitatively compare the wrinkling risks of almost all known 4-edge displays and provide the optimizations for the geometric parameters.

By considering rollable AMOLED displays and applications, optical and mechanical performances are discussed and optimized solutions are introduced. Different color-filter-on-encapsulation (COE) designs for rollable AMOLED are compared in power consumption, L-decay, and reflection. A rollable AMOLED module structure is designed with the impact absorption layer of the hybrid cover. Based on finite element simulation and neutral layer theory, a module stack is optimized and accumulated strain is eliminated. Rollable performance and impact resistance are balanced. A portable device with a rollable AMOLED is developed. Its mechanical design for rollable display application is introduced.
17.4 - Quantifying Surface Quality Due to Periodic Linear Waviness of a Rollable Display (3:00 PM - 3:20 PM)

Rollable displays have a characteristic feature in assessing surface quality that is caused by a periodic supporter structure. In the presence of such periodic deformation, the authors suggest a method to quantify and verify a correlation with human recognition by performing a cognitive experiment. This method can be utilized in assessing the surface quality including any linear and periodic component.
