Overview of the AM arrays in this study. a Schematic diagram of AM array circuit. TFTs are installed at the intersection of the gate and source lines. The PSR sheets are indicated as variable resistors at each pixel. b Cross-section view of one pixel at the AM arrays. Glass substrate is replaced to PET film. c Top view of the AM array, showing a single pixel area with a dotted rectangle. One pixel consists of four rectangular sub-pixel electrodes. A ground electrode surrounds the sub-pixel electrodes. The insertion bar indicates 200 µm. d The pressure-resistance curve of typical SPRs. e A photo of flexible AM array substrate in this study
