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.

First claim

What is claimed is:

1. An electronic display device comprising:
a plurality of light-emitting pixels, each light-emitting pixel having:
one blue light-emitting element, one green light-emitting element, and one red light-emitting element associated therewith,
with the one blue light-emitting element, one green light-emitting element, and one red light-emitting element of each light-emitting pixel being spaced from and in alignment with each other in a first direction,
wherein, for each light-emitting pixel, a first one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element is in a first end position of the light-emitting pixel, a second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element is in a second end position of the light-emitting pixel, and a third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element is in a middle position of the light-emitting pixel and equally spaced from both the first one and the second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of the light-emitting pixel;
a first electronically scannable line comprising a first plurality of the light-emitting pixels equally spaced in a second direction that is perpendicular to the first direction; and
a second electronically scannable line comprising a second plurality of the light-emitting pixels equally spaced in the second direction, the second electronically scannable line being spaced in the first direction in an interleaved manner with respect to the first electronically scannable line such that:
the first one of the blue light emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in the second electronically scannable line is in alignment in the second direction with the second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in the first electronically scannable line,
the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in the first electronically scannable line are in alignment in the second direction with each other,
the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in the second scannable line is in alignment in the second direction with each other; and
the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element do not have an obstructing light-emitting element in the second direction in an adjacent scannable line, wherein the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each of the light-emitting pixels has a view path in a plane in the second direction of up to about 150° due to the lack of an obstructing light-emitting element in the second direction in adjacent scannable lines and wherein the first one and the second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel has a view path in an angled plane up to about 140° due to increased spacing between offset situated light-emitting elements in adjacent scannable lines;

wherein successive electronically scannable lines have the same physical spatial relationship as the first and second electronically scannable lines such that each successive scannable line is interleaved with its preceding scannable line; and
wherein the number of the plurality of electronically scannable lines and the number of pixels in each of the electronically scannable lines is sufficient to provide a predetermined display area.

2. The electronic display device of claim 1 , wherein the green light-emitting element is in the middle position of each light-emitting pixel.

3. The electronic display device of claim 2 , wherein the blue light-emitting element is in the first end position and the red light-emitting element is in the second end position of each light-emitting pixel.

4. The electronic display device of claim 1 , wherein the electronically scannable lines of the light-emitting pixels are spaced, in the first direction, about 12.5 mm on center.

5. The electronic display device of claim 1 , wherein the light-emitting pixels are spaced, in the second direction, about 12.5 mm on center.

6. The electronic display device of claim 1 , wherein the first direction is a generally vertical direction, the second direction is a generally horizontal direction, the first end position is a top position in each of the light-emitting pixels, and the second end position is a bottom position in each of the light-emitting pixels.

7. The electronic display device of claim 1 , wherein the light-emitting elements comprise light-emitting diodes.

8. An electronic display device comprising:
a plurality of electronically scannable lines of light-emitting pixels, the plurality of scannable lines having alternately even-numbered scannable lines and odd-numbered scannable lines;
each of the plurality light-emitting pixels having:
three light-emitting elements associated therewith, including one blue light-emitting element, one green light-emitting element, and one red light-emitting element, the three light-emitting elements in each light-emitting pixel being spaced from and in alignment with each other in a first direction,
wherein, for each light-emitting pixel, a first one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of the light-emitting pixel is in a first end position of the light-emitting pixel, a second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element is in a second end position of the light-emitting pixel, and a third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element is in a middle position of the light-emitting pixel and is equally spaced from both the first one and the second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element;

wherein each of the even-numbered scannable lines includes a first plurality of the light-emitting pixels spaced in a second direction that is perpendicular to the first direction and each of the odd-numbered scannable lines includes a second plurality of the light-emitting pixels spaced in the second direction;
wherein each of the odd-numbered electronically scannable lines is spaced in an interleaved manner with respect to each of the even-numbered electronically scannable lines so that:
the first one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in one of the odd-numbered electronically scannable line lines is in alignment in the second direction with the second one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of each light-emitting pixel in an adjacent even-numbered electronically scannable line,
the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of the light-emitting pixels in each of the even-numbered electronically scannable lines are in alignment with each other in the second direction,
the third one of the blue light-emitting element, the red light-emitting element, or the green light-emitting element of the light-emitting pixel
