Abstract

Aspects of the subject technology relate to displays for electronic devices and methods of operating the displays. The display may include an array of display pixels arranged in rows and columns. A v-drive operation in which rows are alternatingly operated about a center of each of two halves of the display is provided. Data rendering operations are provided that generate a virtual frame rate boost.

First claim

What is claimed is:

1. An electronic device with a display, the display comprising:
an array of display pixels including:
a first half on a first side of a center of the array, and
a second half on a second side of the center of the array; and display control circuitry configured to:
alternatingly operate pixels rows on first and second sides of a center of the first half of the array of display pixels to display a first portion of a display frame in a split-screen mode of operation; and
alternatingly operate pixels rows on first and second sides of a center of the second half of the array of display pixels to display a second portion of the display frame in the split-screen mode of operation.

2. The electronic device of claim 1 , wherein the display control circuitry is further configured to sequentially operate all of the pixels rows of the array to display another display frame.

3. The electronic device of claim 2 , wherein the display frame corresponds to a virtual-reality mode of operation or an augmented-reality mode of operation for the display.

4. The electronic device of claim 3 , wherein the other display frame corresponds to a full-screen mode of operation for the display.

5. The electronic device of claim 1 , wherein the display control circuitry is configured to alternatingly operate the pixels rows on the first and second sides of the center of the first half of the array of display pixels to display the first portion of the display frame by:
operating a centermost pixel row of the pixels rows on the first side of the center of the first half of the array;
operating, immediately after the centermost pixel row of the pixels rows on the first side of the center of the first half of the array, a centermost pixel row of the pixels rows on the second side of the center of the first half of the array; and
operating, immediately after the centermost pixel row of the pixels rows on the second side of the center of the first half of the array, a pixel row that is adjacent to the centermost pixel row of the pixels rows on the first side of the center of the first half of the array.

6. The electronic device of claim 5 , wherein the display control circuitry is configured to alternatingly operate the pixels rows on the first and second sides of the center of the second half of the array of display pixels to display the second portion of the display frame by:
operating a centermost pixel row of the pixels rows on the first side of the center of the second half of the array;
operating, immediately after the centermost pixel row of the pixels rows on the first side of the center of the second half of the array, a centermost pixel row of the pixels rows on the second side of the center of the second half of the array; and
operating, immediately after the centermost pixel row of the pixels rows on the second side of the center of the second half of the array, a pixel row that is adjacent to the centermost pixel row of the pixels rows on the first side of the center of the second half of the array.

7. The electronic device of claim 1 , wherein the display control circuitry is further configured to:
illuminate the first half of the array after alternatingly operating the pixels rows on the first and second sides of the center of the first half of the array of display pixels; and
illuminate the second half of the array after alternatingly operating the pixels rows on the first and second sides of the center of the second half of the array of display pixels.

8. A method of operating a display for an electronic device, the display comprising an array of display pixels, the array including a first half on a first side of a center of the array, and a second half on a second side of the center of the array, the method comprising:
alternatingly operating pixels rows on first and second sides of a center of the first half of the array of display pixels to display a first portion of a display frame in a split-screen mode of operation; and
alternatingly operating pixels rows on first and second sides of a center of the second half of the array of display pixels to display a second portion of the display frame in the split-screen mode of operation.

9. The method of claim 8 , further comprising sequentially operating all of the pixels rows of the array to display another display frame.

10. The method of claim 9 , wherein the display frame corresponds to a virtual-reality mode of operation or an augmented-reality mode of operation for the display.

11. The method of claim 10 , wherein the other display frame corresponds to a full-screen mode of operation for the display.

12. The method of claim 8 , wherein alternatingly operating the pixels rows on the first and second sides of the center of the first half of the array of display pixels to display the first portion of the display frame comprises:
operating a centermost pixel row of the pixels rows on the first side of the center of the first half of the array;
operating, immediately after the centermost pixel row of the pixels rows on the first side of the center of the first half of the array, a centermost pixel row of the pixels rows on the second side of the center of the first half of the array; and
operating, immediately after the centermost pixel row of the pixels rows on the second side of the center of the first half of the array, a pixel row that is adjacent to the centermost pixel row of the pixels rows on the first side of the center of the first half of the array.

13. The method of claim 12 , wherein alternatingly operating the pixels rows on the first and second sides of the center of the second half of the array of display pixels to display the second portion of the display frame comprises:
operating a centermost pixel row of the pixels rows on the first side of the center of the second half of the array;
operating, immediately after the centermost pixel row of the pixels rows on the first side of the center of the second half of the array, a centermost pixel row of the pixels rows on the second side of the center of the second half of the array; and
operating, immediately after the centermost pixel row of the pixels rows on the second side of the center of the second half of the array, a pixel row that is adjacent to the centermost pixel row of the pixels rows on the first side of the center of the second half of the array.

14. The method of claim 8 , further comprising:
illuminating the first half of the array after alternatingly operating the pixels rows on the first and second sides of the center of the first half of the array; and
illuminating the second half of the array after alternatingly operating the pixels rows on the first and second sides of the center of the second half of the array.

15. The method of claim 14 , wherein illuminating the first half of the array comprises concurrently illuminating the entire first half of the array, and wherein illuminating the second half of the array comprises concurrently illuminating the entire second half of the array.

16. The method of claim 14 , wherein illuminating the first half of the array comprises separately illuminating multiple zones of the first half of the array, and wherein illuminating the second half of the array comprises separately illuminating multiple zones of the second half of the array.

17. An electronic device having a display, the display comprising:
an array of display pixels having a first portion and a second portion; and
display control circuitry having multiple processing resources to provide a frame rate booster is configure
