Abstract

An interpolated flat-panel display comprises a display substrate, pixel controllers disposed in a controller array over the display substrate, and pixels disposed in a pixel array over the display substrate. Each pixel controller is connected to one or more control lines and is operable to output pixel information. Each pixel is operable to emit light in response to pixel information received from a pixel controller. The pixel array is larger than the controller array, each pixel is connected to at least one pixel controller, and at least some pixels are interpolated pixels connected to at least two pixel controllers and are operable to emit light in response to pixel information received from the at least two pixel controllers.

Claims (37)

1. An interpolated flat-panel display, comprising:

a display substrate;

pixel controllers disposed in a controller array over the display substrate, each of the pixel controllers connected to one or more control lines and operable to output pixel information received from the one or more control lines; and

pixels disposed in a pixel array over the display substrate, each pixel operable to emit light in response to pixel information received from at least one of the pixel controllers,

wherein the number of pixels in the pixel array is larger than the number of pixel controllers in the controller array, and

at least some of the pixels are interpolated pixels that are connected to at least two of the pixel controllers and are operable to combine pixel information received from the at least two of the pixel controllers and emit light in response to the combined pixel information.

2. The interpolated flat-panel display of claim 1 , wherein the pixel array has a larger size than the controller array has in one dimension.

3. The interpolated flat-panel display of claim 2 , wherein at least some of the interpolated pixels are connected to adjacent ones of the pixel controllers in one dimension.

4. The interpolated flat-panel display of claim 1 , wherein the pixel array has a larger size than the controller array has in two dimensions.

5. The interpolated flat-panel display of claim 1 , wherein at least some of the pixels (i) comprise a programmable memory or internally programmable wires or (ii) are electrically connected to externally programmable wires, indicating a number of connections to pixel controller(s) from which pixel information is received.

6. The interpolated flat-panel display of claim 1 , wherein each of the interpolated pixel comprises (i) a calculation circuit operable to calculate a light-output value in response to receiving pixel information, (ii) a light emitter, and (iii) a drive circuit operable to drive the light emitter in response to the calculated light-output value when received from the calculation circuit.

7. The interpolated flat-panel display of claim 6 , wherein the calculation circuit is electrically connected to receive respective pixel information from a plurality of pixel information inputs and is operable to calculate an average of the received respective pixel information.

8. The interpolated flat-panel display of claim 1 , wherein the interpolated pixels comprise only green light emitters that emit green light in response to pixel information received from the at least two pixel controllers.

9. The interpolated flat-panel display of claim 1 , wherein the array of pixels comprises a subarray of double pixels each comprising a pair of the interpolated pixels.

10. The interpolated flat-panel display of claim 9 , wherein each of the interpolated pixels in each of the double pixels is operable to emit light at one-half brightness as compared to other pixels in the array of pixels that are not in one of the double pixels.

11. The interpolated flat-panel display of claim 1 , wherein, for each of the pixel controllers, each of the pixels electrically connected to the pixel controller is commonly electrically connected to an output of the pixel controller.

12. The interpolated flat-panel display of claim 1 , wherein ones of the pixels in the array of pixels that are not interpolated are disposed on or adjacent to respective pixel controllers in the array of pixel controllers.

13. The interpolated flat-panel display of claim 1 , wherein the pixels are substantially identical.

14. The interpolated flat-panel display of claim 1 , wherein the pixels are each electrically connected to a same number of pixel information inputs such that at least some of the pixels are electrically connected to multiple respective pixel information inputs that are connected to a respective same one of the pixel controllers.

15. An interpolated flat-panel display, comprising:

a display substrate;

pixel controllers disposed in a controller array over the display substrate, each of the pixel controllers connected to one or more control lines and operable to output pixel information received from the one or more control lines; and

pixels disposed in a pixel array over the display substrate, each pixel operable to emit light in response to pixel information received from at least one of the pixel controllers,

wherein the number of pixels in the pixel array is larger than the number of pixel controllers in the controller array, and

at least some of the pixels are interpolated pixels that are connected to at least two of the pixel controllers and are operable to emit light in response to pixel information received from the at least two of the pixel controllers,

wherein the interpolated pixels are each connected to each of exactly two of the pixel controllers with a respective pixel information input.

16. The interpolated flat-panel display of claim 15 , wherein less than all of the pixels are the interpolated pixels and the pixels that are not the interpolated pixels are connected to one of the pixel controllers with two pixel information inputs.

17. An interpolated flat-panel display, comprising:

a display substrate;

pixel controllers disposed in a controller array over the display substrate, each of the pixel controllers connected to one or more control lines and operable to output pixel information received from the one or more control lines; and

pixels disposed in a pixel array over the display substrate, each pixel operable to emit light in response to pixel information received from at least one of the pixel controllers,

wherein the number of pixels in the pixel array is larger than the number of pixel controllers in the controller array, and

at least some of the pixels are interpolated pixels that are connected to at least two of the pixel controllers and are operable to emit light in response to pixel information received from the at least two of the pixel controllers,

wherein at least some of the interpolated pixels are each connected to each of exactly four of the pixel controllers with a respective pixel information input.

18. The interpolated flat-panel display of claim 17 , wherein at least some of the interpolated pixels are connected to each of exactly two of the pixel controllers with a respective pixel information input.

19. The interpolated flat-panel display of claim 17 , wherein the interpolated pixels are less than all of the pixels and at least some of the pixels that are not interpolated are electrically connected to one of the pixel controllers with four pixel information inputs.

20. The interpolated flat-panel display of claim 19 , wherein at least some of the interpolated pixels are electrically connected to exactly two of the pixel controllers with a total of four pixel information inputs.
