Abstract

Apparatuses and methods for forming displays are claimed. This invention relates to a display which may be conformal and which can receive information in order to alter or configure the display. In one embodiment, a flexible layer may be made to receive an array of blocks which drive a display material to provide an alterable or configurable display. This display is coupled to a receiver which receives data and drives the data onto the blocks causing the display to change. The receiver (and blocks) may be powered by a signal from a transmitter which beams the information to the receiver. The receiver in turn controls the update of the display information on the display. Another embodiment of the invention has a receiver coupled to each block. The receiver also may be independent from the block and may be deposited onto the flexible layer.

Claims

1. A method of manufacturing a flexible display comprising:

depositing a plurality of shaped blocks, each having an active circuitry for a display driver, onto a flexible web substrate, said flexible web substrate having a plurality of recessed regions configured to receive said plurality of shaped blocks therein, at least one of each of said shaped blocks comprising an active circuit element for driving a picture element; and

coupling a receiver to the plurality of shaped blocks on the flexible web substrate, the receiver transmitting signals to the said shaped blocks to cause the active circuit element of at least one of said shaped blocks to drive the picture element;

wherein at least a portion of said flexible web substrate having said plurality of blocks deposited therein forms a backplane for said flexible display; and

coupling a display panel to said backplane to form said flexible display, wherein the display panel is coupled to said backplane in a continuous web process line that is used to deposit said plurality of shaped blocks and said receiver to said web substrate.

2. The method of claim 1, wherein said flexible display conforms to a desired shape of an object when said flexible display is attached to said object.

3. The method of claim 1, further comprising:

coupling a display generation substrate to said flexible web substrate.

4. The method of claim 1, wherein said flexible display comprises an active matrix display backplane which comprises at least one electrode for each picture element.

5. The method of claim 1, further comprises checking the web substrate for any empty recessed region using an electronic device and filling the empty recessed region.

6. The method of claim 1, wherein the flexible display has an organic light emitting diode.

7. The method of claim 1, wherein the flexible display comprises upconverting phosphor.

8. The method of claim 1, wherein the receiver is a RF wireless transponder receiver.

9. The method of claim 1 wherein said coupling a receiver to the plurality of blocks on the web material further comprises depositing said receiver onto said web material.

10. The method of claim 9 wherein said receiver causes information on said flexible display panel to change.

11. The method of claim 1 wherein each of said shaped block comprises single crystal silicon.
