1. An electronic display device comprising: a. a plurality of electronically scannable lines of LED pixels, each LED pixel having one blue LED, one green LED, and one red LED associated therewith, with said one blue LED, one green LED, and one red LED of each LED pixel being spaced from and in vertical alignment with each other, said blue LED being in the top position, said red LED being in the bottom position, and said green LED being in the middle position, and equally spaced from both said blue LED and said red LED;b. a first electronically scannable line having a plurality of equally and horizontally spaced LED pixels;c. a second electronically scannable line having a plurality of equally and horizontally spaced LED pixels, said second electronically scannable line being spaced in an interleaved manner with respect to said first electronically scannable line such that the blue LEDs of each LED pixel in said second electronically scannable line are in horizontally spaced alignment with the red LEDs of each LED pixel in said first electronically scannable line, said green LEDs in said first electronically scannable line being in horizontal alignment with each other, said green LEDs in said second scannable line being in horizontal alignment with each other, successive electronically scannable lines having the same physically spatial relationship as said first and second electronically scannable lines such that each successive scannable line is interleaved with its preceding scannable line and the number of said plurality of scannable lines and the number of pixels in each of said electronically scannable lines and the number of pixels in each of said electronically scannable lines being sufficient to provide a predetermined display area; and,d. wherein the green LEDs have a view path, in a horizontal plane, up to about 150°, due to the lack of an obstructing horizontally situated LED in adjacent scanning lines and wherein the red LEDs and the blue LEDs have a view path, in an angled plane, up to about 140°, due to the increased spacing between the offset situated LEDs in adjacent scanning lines. 2. The electronic display device of claim 1, wherein the LED pixels are horizontally spaced about 12.5 mm on center. 3. The electronic display device of claim 1, wherein the electronically scannable lines of LED pixels are vertically spaced about 12.5 mm on center. 4. The electronic display device of claim 1, wherein the scan lines extending through the LED pixels include two scan lines per LED pixel. 5. The electronic display device of claim 1, wherein said plurality of electronically scannable lines of LED pixels are positioned and supported on a circuit board. 6. The electronic display device of claim 1, wherein said electronic display device is an electronic display sign. 7. An electronic display device comprising: a. a plurality of electronically scannable lines of LED pixels, said plurality of scannable lines having alternately even numbered scannable lines and odd numbered scannable lines, each LED pixel having three LEDs associated therewith, with one blue LED, one green LED, and one red LED, said three LEDs in each LED pixel being spaced from and in vertical alignment with each other, with said blue LED being in the top position, said red LED being in the bottom position, and said green LED being in the middle position, and equally spaced from both said blue LED and said red LED, each of said even numbered scannable lines having a plurality of horizontally spaced pixels, each of said odd numbered scannable lines having a plurality of horizontally spaced pixels, each of said odd numbered electronically scannable lines being spaced in an interleaved manner with respect to each of said even numbered electronically scannable lines such that the blue LEDs of each pixel in said odd numbered electronically scannable line are in horizontally spaced alignment with the red LEDs of each pixel in said even numbered electronically scannable line, said green LEDs in each of said even numbered electronically scannable lines being in horizontal alignment with each other, said green LEDs in each of said odd numbered scannable lines being in horizontal alignment with each other, successive electronically scannable lines having the same physically spatial relationship as said even numbered and odd numbered electronically scannable lines such that each successive scannable line is interleaved with its preceding scannable line and the number of said plurality of scannable lines and the number of pixels in each of said electronically scannable lines being sufficient to provide a predetermined display area. 8. The electronic display device of claim 7, wherein said plurality of electronically scannable lines of LED pixels are positioned and supported on a circuit board. 9. The electronic display device of claim 7, wherein said electronic display device is an electronic display sign. 10. The electronic display device of claim 7, wherein the LED pixels are horizontally spaced about 12.5 mm on center. 11. The electronic display device of claim 7, wherein the electronically scannable lines of LED pixels are vertically spaced about 12.5 mm on center. 12. The electronic display device of claim 7, wherein the scan lines extending through the LED pixels include two scan lines per LED pixel. 13. A pixel interleave configuration for an electronic sign, the pixel interleave configuration comprising: a. a plurality of LED pixels, each of the LED pixels having, in vertical arrangement, a lower situated red LED, an upper situated blue LED, and a green LED situated between the red LED and the blue LED, the LED pixels of the plurality of LED pixels arranged in horizontally oriented rows of regularly spaced apart LED pixels, the rows alternatingly defining odd and even rows of the LED pixels of the plurality of LED pixels, and the LED pixels of the plurality of LED pixels further arranged in vertically oriented columns of regularly spaced apart LED pixels, the columns alternatingly defining odd and even columns, the even columns being offset relative to the odd columns, such that the even columns are displaced vertically by about half of the spacing between LED pixels of the column, relative to the LED pixels of the odd columns, and the even rows being offset relative to the odd rows, such that the even rows are displaced horizontally by about half of the spacing between LED pixels of the rows, relative to the LED pixels of the odd rows, and with each LED pixel of the plurality of LED pixels having a row and a column address;b. wherein the red LED, blue LED, and green LED on each of the LED pixels of the plurality of LED pixels are sequentially addressed and controlled by horizontal scan lines, the horizontal scan lines separated by about half an LED pixel spacing of an LED pixel column, such that each LED pixel has the red LED, the blue LED, and the green LED being addressed in at least two distinct horizontal scan lines, the scan lines sequentially scanningly activated according to an image to be displayed;c. wherein each of the horizontal scan lines defines real time pixels along each horizontal scan line, each real time pixel consisting of a red LED, a blue LED, and a green LED, at least one of the red LED, the blue LED, and the green LED of the real time pixel residing on an LED pixel adjacent to the LED pixel on which the other LEDs of the real time pixel reside and at least one of the two adjacent LED pixels is in an offset column of LED pixels; and,d. further wherein the green LEDs have a view path, in a horizontal plane, up to about 150°, due to the lack of an obstructing horizontally situated LED in adjacent scanning lines and wherein the red LEDs and the blue LEDs have a view path, in an angled plane, up to about 140°, due to the increased spacing between the offset situated LEDs in adjacent scanning lines. 14. The electronic display device of claim 13, wherein the LED pixels are horizontally spaced about 12.5 mm on center. 15. The electronic display device of claim 13, wherein the electronically scannable lines of LED pixels are vertically spaced about 12.5 mm on center. 16. The electronic display device of claim 13, wherein the scan lines extending through the LED pixels include two scan lines per LED pixel.
