The price tag system of the present invention has the advantages of reliability, easy to install and low cost. Using the system of the invention, the prices can be easily updated even from a remote location. In addition, if there is one defective panel, the defective panel can be easily removed and replaced without any changes made to the base structure, which also greatly reduces the operation costs.

A matrix driven electrophoretic display with a multi-layer back plane is disclosed. The display comprises a top electrode layer, a display cell layer, and a multi-layer back plane. In one embodiment, the multi-layer back plane comprises an electrode formed on the top surface of the top substrate of the multi-layer back plane, a conductive via structure through the substrate, and a conductive trace connected electrically to the via structure at the bottom surface of the first substrate, whereby an electrical connection may be made from the electrode to a structure or component not located immediately beneath the electrode in the multi-layer back plane. In other embodiments, the multi-layer back plane may comprise additional layers and via holes, as needed to connect the electrode with the appropriate switching elements and/or driver elements, as applicable. Such switching and driver elements, integrated with multi-layer back plane.

The present invention generally is directed to electrode designs suitable for roll-to-roll format flexible manufacturing of an EPD. It is also directed to an EPD having a segment design in a repeated pattern across an entire roll of the display. The EPD preferably is microcup-based. The EPD manufactured according to the present invention has the appearance of a roll of wall paper and it can be cut into any desired sizes or formats. The EPD has electrode or trace lines which may be exposed by asymmetrical cutting and stripping without the need of precision registration.

The present invention is directed to a process which comprises removing and stripping off part of the display panel in order to expose and connect the conductor lines on an electrode plate to a driver circuitry. More specifically the process involves (1) preparing a display panel having filled display cells sandwiched between a first and a second substrate layers, preferably by a roll-to-roll process; (2) removing part of a first substrate by asymmetrical cutting by, for example, a die, diamond, knife or laser cutting method to expose the layers underneath (which may include adhesive layer, primer layer, display cell layer and in the case of a display prepared by the microcup technology, the microcup layer and the sealing layer); and (3) stripping off the exposed layers by a stripping solvent or solution. After stripping, the conductor lines on the second substrate are exposed and ready for connection to the driver circuitry.
