Display device with chiplets and hybrid drive

1. An imaging device having a hybrid drive, comprising:

a) a single continuous substrate;

b) a two-dimensional pixel array formed on the substrate, the pixels associated into a plurality of pixel groups, each pixel group including at least four pixels and including a separate set of group row electrodes and group column electrodes connected to and driving only the pixels in the corresponding pixel group, each of the group row electrodes connected to two or more pixels and each of the group column electrodes connected to two or more pixels, so that a single group row electrode together with a single group column electrode drives a single pixel; and

c) two or more chiplets located over the substrate and within the pixel array, each chiplet associated with a pixel group and having connections to each of the associated group row electrodes and associated group column electrodes and having at least as many storage elements as are in either dimension of the pixel group, the storage element storing a value representing a desired luminance for a pixel and the chiplet using the value to control the desired luminance of each pixel in its associated pixel group.

2. The imaging device of claim 1 , including one or more buses electrically connected to each chiplet.

3. The imaging device of claim 2 , wherein at least one of the one or more buses is a serial bus connected serially through at least two or more chiplets.

4. The imaging device of claim 2 , wherein at least one of the one or more buses is a parallel bus connected in common to the chiplets.

5. The imaging device of claim 4 , wherein the parallel bus provides a power or ground electrical connection.

6. The imaging device of claim 2 , wherein a bus transmits a data signal.

7. The imaging device of claim 2 , wherein at least one of the one or more bus connections is a parallel bus and at least one of the one or more bus connections is a serial bus.

8. The imaging device of claim 2 , wherein at least one of the one or more buses is connected to all of the chiplets in one column of the chiplet array or at least one bus is connected to all of the chiplets in one row of the two or more chiplets.

9. The imaging device of claim 1 , wherein each of the pixel groups forms a rectangular array of pixels.

10. The imaging device of claim 1 , wherein the storage element is an analog storage element, a capacitor storing charge, or a digital storage element.

11. The imaging device of claim 1 , wherein the device is a non-emissive display device.

12. The imaging device of claim 1 , wherein the device is an image capture device.

13. The imaging device of claim 1 , wherein the chiplets are identical.

14. The imaging device of claim 1 , wherein each chiplet has a unique identifier.

15. The imaging device of claim 14 , wherein the unique identifier of each chiplet is established after the chiplets are located over the substrate and the unique identifier of each chiplet corresponds to a relative position of each chiplet in the two-dimensional chiplet array.

16. The imaging device of claim 1 , further comprising control chiplets located around the periphery of the two or more chiplets for driving the chiplets.

17. The imaging device of claim 1 , wherein the size of each chiplet is determined by the number of connections to the chiplet.

18. The imaging device of claim 1 , wherein the device is a display device.

19. The imaging device of claim 18 , wherein the device is an organic LED display device or an inorganic LED display device.

20. The imaging device of claim 1 , wherein each chiplet is connected to at least two group row electrodes and two group column electrodes.
