Abstract
The display of the future is multimodal, integrating optical sensors, RFID antennas, ultrasound transducers, etc. The sensors produce a large amount of redundant data, which should be preprocessed on the substrate, ideally on the backpanel. Control gates and select and data drivers need to be more configurable and partitionable to create operational flexibility. This paper presents various circuit blocks for processing and control, including operational amplifiers, high‐resolution analog‐to‐digital converters, a microprocessor, DC‐DC converters, and high resolution sensor pixel array architectures. Moreover, the performance of the basic building blocks is compared in LTPS and IGZO technology.
