Color flat panel display arrangements and layouts with reduced blue luminance well visibility
View Patent ↗A transflective display panel substantially comprises a plurality of a sub-pixel grouping substantially comprising a plurality of at least first and second color sub-pixels. The plurality of the sub-pixel grouping forms an array across said display panel in a plurality of rows and columns. The first color sub-pixel is a substantially dark color sub-pixel disposed in the plurality of the sub-pixel grouping across said display panel so as to form a substantially vertical line down said display. Each sub-pixel further comprises an optical via, and the optical vias are formed in non-uniform positions upon said dark color sub-pixels.
1. A transflective display panel substantially comprising:
a sub-pixel grouping comprising a plurality of at least first and second color sub-pixels, and forming an array across said display panel in a plurality of rows and columns;
said first color sub-pixels being substantially dark color sub-pixels as compared to the second color sub-pixels disposed in said sub-pixel grouping across said display panel so as to form a substantially vertical line on said display panel;
wherein each of the first and second color sub-pixels further comprises an optical via configured to transmit a backlight light from within the respective sub-pixel;
wherein said optical vias in the first color sub-pixels are formed in non-uniform positions;
wherein a relative position of a first optical via in one of the first color sub-pixels in the sub-pixel grouping is different from a relative position of a second optical via in an adjacent first color sub-pixel in the sub-pixel grouping.
2. The display panel as recited in claim 1 wherein forming said optical vias in non-uniform positions upon said dark color sub-pixels causes the phase of the reconstruction points of said dark color sub-pixels to shift; and further wherein said optical vias are formed upon said dark color sub-pixels such that the phase of the reconstruction points of said dark color sub-pixels is shifted in the vertical axis.
3. The display panel as recited in claim 1 wherein forming said optical vias in non-uniform positions upon said dark color sub-pixels causes the phase of the reconstruction points of said dark color sub-pixels to shift; and further wherein said optical vias are formed upon said dark color sub-pixels such that the phase of the reconstruction points of said dark color sub-pixels is shifted in the horizontal axis.
4. The display panel as recited in claim 1 wherein said sub-pixel grouping is comprised of two rows of sub-pixels, and wherein a dark color sub-pixel compared to the second color sub-pixels is disposed in each row of sub-pixels; and
further wherein said optical vias are formed in non-uniform positions upon said dark color sub-pixels compared to the second color sub-pixels within said sub-pixel grouping.
5. The display panel as recited in claim 1 wherein said sub-pixel grouping is comprised of two row and three columns of sub-pixels, and wherein a dark color sub-pixel compared to the second color sub-pixels is disposed in each row of sub-pixels; and further wherein said optical vias are formed in non-uniform positions upon said dark color sub-pixels compared to the second color sub-pixels within said sub-pixel grouping.
6. The display panel as recited in claim 5 wherein said dark color sub-pixels disposed in each row of sub-pixels are further disposed in different columns of said sub-pixel grouping.
7. The display panel as recited in claim 1 wherein said sub-pixels are formed on said display panel with their length-wise edges on a horizontal axis.
8. The display panel as recited in claim 1 wherein said first color sub-pixel includes a blue sub-pixel.
9. The display panel as recited in claim 1 wherein said second color sub-pixel includes at least one of a red sub-pixel and a green sub-pixel.
10. The display panel as recited in claim 1 wherein the sub-pixel grouping comprises a first sub-pixel grouping including first and second color sub- pixels and a second sub-pixel grouping including first and second color sub-pixels, the second sub-pixel being adjacent to the first sub-pixel grouping in a horizontal direction, and
a position of an optical via in the first color sub-pixel of the first sub-pixel grouping is different from a position of an optical via in the first color sub-pixel of the second sub-pixel grouping.
11. The display panel as recited in claim 10 wherein a vertical position of the optical via in the first color sub-pixel of the first sub-pixel grouping is different from a vertical position of the optical via in the first color sub-pixel of the second sub-pixel grouping.
12. The display panel as recited in claim 10 wherein a position of an optical via in a second color sub-pixel of the first sub-pixel grouping is the same as a position of an optical via in a second color sub-pixel of the second sub-pixel grouping corresponding to the second color sub-pixel of the first sub-pixel grouping.
13. The display panel as recited in claim 10 wherein the first sub-pixel grouping includes a first second color sub-pixel adjacent to the first color sub-pixel in a first direction, and a second second color sub-pixel adjacent to the first color sub-pixel in a second direction opposite to the first direction, and
a position of an optical via in the first second color sub-pixel of the first sub-pixel grouping is different from a position of an optical via in the second second color sub-pixel of the first sub-pixel grouping.
