The present invention relates to devices and methods for the application of one or more colours to a reflective display system, such as an electrophoretic display, wherein the colours are applied to one or more regions of the display where colour is desired.

The present invention relates to an electrophoretic light shutter display, more specifically, to a multi-stable transmissive electrophoretic light shutter display employing symmetric electrode patterning. The basic unit consists of four pixels with four identical square transparent electrodes connected with quadruple thin film transistors on the first substrate, an overlapped circular electrode on the second substrate, and a cell of electrophoretic particle dispersion fluid sandwiched between the first and second substrates. When an electric pulse is applied to any one of the pixels with a predetermined polarity, the colored charged particles will be able to move fan-in or fan-out radially with a linear grayscale. Therefore, the total transmission of the incident light through the shutter can be electronically modulated and maintained for good in zero-field conditions.
