In this study, we proposed a strain-sensor-in-pixel (S-SIP) system by introducing hidden pixels that are activated only when the display is stretched to maintain the pixel density. For the system, the strain-sensor integrated InGaZnO thin-film transistors (TFTs) were fabricated to control the TFT on/off operation depending on the stretching state.
