CLAIMS

1. A light modulator (402) comprising:
a control unit (502) configured to receive an image input signal (406); and an array (504) comprising a plurality of pixels arranged in a plurality of rows;
wherein the control unit is configured to provide a first address associated with the image input signal to the array in response to detecting a first mode of operation, wherein the control unit is configured to provide a second address associated with the image input signal to the array in response to detecting a second mode of operation, wherein the array is configured to drive a first one of the plurality of rows in response to receiving the first address, and wherein the array is configured to drive the first one of the plurality of rows and a second one of the plurality of rows in response to receiving the second address.

2. The light modulator of claim 1 wherein the first one of the plurality of rows is adjacent to the second one of the plurality of rows.

3. The light modulator of claim 1 wherein the control unit is configured to provide an inversion of the first address to the array in response to detecting the first mode of operation, wherein the control unit is configured to provide a third address to the array in response to detecting the second mode of operation, wherein a first portion of the third address includes an inversion of a first portion of the second address, and wherein a second portion of the third address is equal to a second portion of the second address.

4. The light modulator of claim 3 wherein the second portion of the third address includes a single bit.

5. The light modulator of claim 1 wherein the first mode of operation includes a normal mode of operation, and wherein the second mode of operation includes a sub-frame mode of operation.

6. The light modulator of claim 1 wherein the control unit is configured to detect the second mode of operation in response to receiving a mode select signal (408).

7. The light modulator of claim 1 wherein the control unit is configured to detect the second mode of operation using information accessible by the control unit.

8. The light modulator of claim 1 wherein the array includes a decode unit (506) and a pixel array (508) that includes the plurality of pixels, wherein the decode unit is configured to provide a first row selector signal (510A) to the pixel array in response to receiving the first address, and wherein the decode unit is configured to provide the first row selector signal and a second row selector signal (510B) to the pixel array in response to receiving the second address.

9. A method performed by a light modulator (402) comprising:
receiving an image input signal (406);
providing a first address and a second address to an array (504) having a plurality of pixels arranged in a first row and a second row in response to detecting a first mode of operation;
providing a third address and a fourth address to the array in response to detecting a second mode of operation;
activating the first row in response to receiving the first address and the second address at the array; and
activating the first row and the second row in response to receiving the third address and the fourth address at the array.

10. The method of claim 9 further comprising: generating the first address; and
generating the second address by inverting the first address.

11. The method of claim 9 further comprising:
generating the third address; and
generating the fourth address by inverting the third address and setting a portion of the fourth address equal to a corresponding portion of the third address.

12. The method of claim 9 wherein the first one of the plurality of rows is adjacent to the second one of the plurality of rows.
