Abstract

A multilayered thin, lightweight, flexible, bright, wireless display having components capable of being manufactured by a printing method. A flexible substrate provides a support structure upon which components can be manufactured by a printing method. A display stratum includes light emitting pixels for displaying information. The light emitting pixels are formed by printing a pixel layer of light-emitting conductive polymer. An electronic circuit stratum includes signal transmitting components for transmitting user input signals to a display signal generating device for controlling display information transmitted from the display signal generating device. Signal receiving components receive the display information transmitted from the display signal generating device. Display driving components drive the display layer according to the received display information. A user input stratum receives user input and generates the user input signals. A battery stratum provides electrical energy to the electronic circuit stratum, the user input stratum and display stratum components. The signal receiving components may include first radio frequency receiving components for receiving a first display signal having first display information carried on a first radio frequency and second radio frequency receiving components for receiving a second display signal having second display information carried on a second radio frequency. The display driving components may include signal processor components for receiving the first display signal and the second display signal and generating a display driving signal for simultaneously displaying the first display information at a first location on the display stratum and the second display information at a second location on the display stratum. At least some of the components in the battery, display, user input and electronic circuit stratums are formed by printing electrically active material to form circuit elements including resistors, capacitors, inductors, antennas, conductors and semiconductor devices.
