Display device with an array of display drivers recessed onto a substrate
View Patent ↗Apparatuses and methods for forming displays are claimed. One embodiment of the invention relates to dispensing display drivers over a substrate. The display drivers, for example, may be a plurality of emitters and gates in order to form a display such as a field emission display (FED). Alternatively, the display drivers may be rods for a plasma display. Another embodiment of the invention relates to forming an electronic device along a length of substrate using template transfer or FSA to deposit display drivers into recessed regions or holes of a substrate. Another embodiment of the invention relates to using FSA and a deterministic method such as “pick and place” to place display drivers onto a substrate. Another embodiment of the invention relates to using donor transfer of display drivers to a substrate.
1. A display device comprising:
a first voltage driver; and
an array of blocks having formed thereon display drivers, each of said blocks being formed from a first substrate and deposited and recessed onto a second substrate, each of said blocks having said display drivers converting a first voltage from said first voltage driver to a second voltage.
2. The display device of claim 1 , wherein a plurality of spacers are deposited onto the second substrate.
3. The display device of claim 1 , wherein a plurality of driver chips are deposited onto the second substrate.
4. The display device of claim 1 , wherein said display device conforms to a desired shape of an object which is planar when said display device is attached to said object.
5. The display device of claim 1 , wherein said display device conforms to a desired shape of an object which is non-planar when said display device is attached to said object.
6. The display device of claim 1 , wherein at least one of blocks with the display drivers formed from the first substrate and deposited and recessed onto the second substrate drives a picture element.
7. The display device of claim 1 , wherein the blocks with the display drivers are rods.
8. The display device of claim 1 , wherein the display drivers are at least one emitter and at least one gate.
9. The display device of claim 1 , wherein a first plurality of shaped blocks having drivers and a second plurality of shaped blocks having drivers are deposited on a substrate.
10. The display device of claim 1 , wherein a plurality of objects are deposited onto the first substrate, the objects are one of display drivers, spacers, emitters, and gates.
11. A display device comprising:
a first voltage driver;
a plurality of first blocks having formed thereon display drivers, each of the first blocks converting a first voltage from the first voltage driver to a second voltage; and a
substrate with a plurality of recessed regions shaped to receive the plurality of first blocks,
wherein the plurality of first blocks are deposited in the plurality of recessed regions.
12. The display device of claim 11 further comprising a plurality of second blocks having formed thereon spacers, the plurality of second blocks being deposited in a plurality of recessed regions in the substrate shaped to receive the plurality of second blocks.
13. The display device of claim 11 further comprising a plurality of third blocks with driver chips, the plurality of third blocks being deposited in a plurality of recessed regions in the substrate shaped to received the plurality of third blocks.
14. The display device of claim 11 wherein the display drivers comprises at least one emitter and at least one gate.
15. The display device of claim 11 wherein the substrate is flexible.
16. The display device of claim 11 wherein the substrate is rigid.
