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 (34)

1. A method of operating a flat-panel display, the method comprising:

providing an active-matrix display comprising an array of pixels and an array of pixel controllers;

providing at least some of the pixels with respective pixel information signals from a respective more than one of the pixel controllers; and

automatically driving one or more light emitters in the at least some of the pixels to emit light based on the respective pixel information signals.

2. The method of claim 1 , wherein driving the one or more light emitters comprises driving the one or more light emitters to emit light based on a combination of the respective pixel information signals.

3. The method of claim 2 , wherein the combination is an average.

4. The method of claim 3 , wherein the average is a weighted average.

5. The method of claim 2 , wherein the combination is a minimum or a maximum of the respective pixels information signals.

6. The method of claim 1 , wherein the respective more than one of the pixel controllers is at least four of the pixel controllers.

7. The method of claim 1 , wherein the active-matrix display comprises a display substrate;

wherein the array of pixel controllers are disposed 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;

wherein the array of pixels is disposed over the display substrate;

wherein the number of pixels in the array of pixels is larger than the number of pixel controllers in the array of pixel controllers;

wherein at least some of the pixels are interpolated pixels that are connected to at least two of the pixel controllers, and

the method comprises, for each of the interpolated pixels, combining, using the interpolated pixel, pixel information signals received from the at least two of the pixel controllers and emitting light in response to the combined pixel information.

8. The method of claim 7 , wherein the interpolated pixels are each connected to each of exactly two of the pixel controllers with a respective pixel information input.

9. The method of claim 8 , wherein the exactly two of the pixel controllers are adjacent in a dimension over the display substrate.

10. The method of claim 7 , 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.

11. The method of claim 7 , 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.

12. The method of claim 11 , wherein the exactly four of the pixel controllers are mutually adjacent over the display substrate.

13. The method of claim 7 , 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.

14. The method of claim 7 , 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.

15. The method of claim 7 , 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.

16. The method of claim 1 , wherein different ones of the pixels in the array of pixels are electrically connected to different numbers of the pixel controllers.

17. The method of claim 1 , wherein each of the pixels comprises:

a pixel substrate;

one or more light emitters; and

a pixel circuit comprising a drive circuit and a calculation circuit,

wherein (i) the pixel circuit is disposed on or in the pixel substrate, (ii) the calculation circuit is operable to send a light-output value to the drive circuit based on pixel information from two or more pixel information inputs upon receiving the pixel information, and (iii) the drive circuit causes the one or more light emitters to emit light in response to receiving the light-output value.

18. The method of claim 1 , wherein each of the pixels comprises:

a pixel substrate;

one or more light emitters; and

a pixel circuit comprising a drive circuit and a programmable memory,

wherein the pixel circuit is disposed on or in the pixel substrate and the programmable memory is operable to store a code that indicates to the pixel circuit a number of pixel information input(s) usable to control the drive circuit to cause the one or more light emitters to emit light.
