Abstract
Two-terminal switching devices of MIM type having at least one electrode formed by a liquid phase processing method are provided for use in active matrix backplane applications; more specifically, MIM devices with symmetric current-voltage characteristics are applied for LCD active matrix backplane applications, and MIM devices with asymmetric current-voltage characteristics are applied for active matrix backplane implementation for electrophoretic displays (EPD) and rotating element displays. In particular, the combination of the bottom metal, metal-oxide insulator and solution-processible top conducting layer enables high throughput, roll-to-roll process for flexible displays.
