  • Abstract
    An integrated mobile LDI with readout function is designed for touch sensor embedded display panels. This device not only drives the display panel but also senses either charge signals or current signals from the TFT sensor array with 8b resolution. The 22 times 1.8mm2 chip consumes 24mW, with 3mW required for the readout function
