Abstract
A display system includes a printed display formed on a substrate and a printed battery in electrical communication with the printed display. The printed display provides power to the printed display. Since both the display and battery are printed, the resulting display system is extremely thin and the manufacture thereof is reliable and inexpensive. The display system contemplates various types of printed displays such as an electrochromic display, a thermochromic display, an electroluminescent display, or an electrophoretic display.
Claims45
A display system, comprising:
- a printed display formed on a substrate;
- and
- a printed battery in electrical communication with the printed display, wherein the printed battery includes a non-activated state and an activated state, wherein the non-activated state allows the printed battery to be stored substantially indefinitely without loss of stored charge and in the activated state the printed battery provides power to the printed display, and
- wherein the non-activated state of the printed battery comprises a separation layer interposed between an anode layer and a cathode layer, wherein the separation layer is selectively removable, thus allowing the anode layer to couple to the cathode layer via an electrolyte layer, thereby placing the printed battery in the activated state.

A display system, comprising:
- a printed display formed on a substrate;
- and
- a printed battery in electrical communication with the printed display, wherein the printed display and printed battery are printed at the same time, wherein the printed battery includes a non-activated state and an activated state, wherein the non-activated state allows the printed battery to be stored substantially indefinitely without loss of stored charge and in the activated state the printed battery provides power to the printed display, and
- wherein the non-activated state of the printed battery comprises a separation layer interposed between an anode layer and a cathode layer, wherein the separation layer is selectively removable, thus allowing the anode layer to couple to the cathode layer via an electrolyte layer, thereby placing the printed battery in the activated state.

A method of producing a display system, comprising the steps of:
- printing a display on a substrate;
- and
- printing a battery in electrical communication with the display, wherein the display and battery are printed at the same time, and
- wherein the printed battery includes a non-activated state and an activated state, wherein the non-activated state allows the printed battery to be stored substantially indefinitely without loss of stored charge and in the activated state the battery provides power to the display, and
- wherein the non-activated state of the printed battery comprises a separation layer interposed between an anode layer and a cathode layer, wherein the separation layer is selectively removable, thus allowing the anode layer to couple to the cathode layer via an electrolyte layer, thereby placing the printed battery in the activated state.

A display system, comprising:
- a printed display formed on a substrate;
- and
- a printed battery in electrical communication with the printed display, wherein the printed battery comprises;
- an anode layer formed over the substrate;
- a cathode layer formed over the substrate, wherein the cathode layer is disposed laterally and spaced apart from the anode layer on the substrate;
- and
- an electrolyte layer formed over the anode layer or the cathode layer,
- wherein the printed battery is in a non-activated state for storage and experiences negligible charge leakage, and
- wherein the substrate is flexible and when folded in a manner to couple the anode layer to the cathode layer with the electrolyte layer therebetween, the printed battery is in an activated state and is operable to provide power to the printed display.
