- Abstract
- AR/VR devices demand ultra-high-resolution displays to accommodate a wide field of view (FOV) and high pixels per degree (PPD). Stacked vertical channel TFTs, which combine vertical channel TFTs with a stacked structure, offer a backplane solution that meets these requirements. By optimizing the structure and process integration, the device characteristics of stacked vertical channel TFTs were well controlled. Using this technology, a pixel design supporting 3500 PPI with a 4T1C configuration was developed.
