Abstract
Pixel interleaving configurations for use in high definition electronic sign displays where each and every scan line includes full red, green, and blue color representation to provide for high resolution electronic video sign displays.
Claims16
An electronic display device, comprising:
- a first odd row of LED pixels, a first even row of LED pixels, a second odd row of LED pixels, and a second even row of LED pixels, wherein the first even row of LED pixels is physically interleaved with the first odd row of LED pixels, the second odd row of LED pixels, the second even row of LED pixels is physically interleaved with the second odd row of LED pixels, each LED pixel having one blue LED, one green LED, and one red LED associated therewith;
- a first scan line of LED groupings, each LED grouping of the first scan line comprising a blue LED selected from one of the LED pixels of the first odd row or from one of the LED pixels of the first even row, a green LED selected from one of the LED pixels of the first odd row or from one of the LED pixels of the first even row, and a red LED selected from one of the LED pixels of the first odd row or from one of the LED pixels of the first even row;
- a second scan line of LED groupings, each LED grouping of the second scan line comprising a blue LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row, a green LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row, and a red LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row;
- and
- a third scan line of LED groupings, each LED grouping of the third scan line comprising a blue LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row, a green LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row, and a red LED selected from one of the LED pixels of the first even row or from one of the LED pixels of the second odd row.
2 more elements
A method of operating an electronic display device, the method comprising:
- providing or receiving at least a first odd row, a first even row, a second odd row, and a second even row of LED pixels, wherein the first even row of LED pixels is physically interleaved with the first odd row and the second odd row of LED pixels and the second even row is physically interleaved with the second odd row, each LED pixel having one blue LED, one green LED, and one red LED associated therewith;
- and
- individually controlling each of a plurality of LED groupings, including a blue LED, a green LED, and a red LED selected from adjacent even and odd rows, to form a first scan line by controlling LEDs from the first odd row and the first even row, a second scan line by controlling LEDs from the first even row and the second odd row, and a third scan line by controlling LEDs from the second odd row and the second even row.
