Abstract (en)

[origin: WO2023009480A1] An electrophoretic display having a plurality of display pixels, each of the plurality of display pixels may include a pixel electrode for driving the display pixel, a single thin film transistor (TFT) coupled to the pixel electrode for transmitting waveforms to the pixel electrode, a front plane laminate (FPL) coupled to the single thin film transistor, and a storage capacitor coupled to the pixel electrode and placed in parallel with the FPL, where the storage capacitor is configured to be sufficiently ohmically conductive to allow the discharge of remnant voltages from the FPL through the storage capacitor.
