OLED displays with varying sized pixels
View Patent ↗An active matrix OLED display has pixels with light emitting areas arranged in rows and columns and includes; a first pixel having a first height in the column direction and disposed in a first column of pixels and in a first row of pixels; a second pixel having a second height in the column direction and disposed in the first column of pixels and in a second row of pixels wherein the second row of pixels is adjacent to the first row of pixels and the first height being different than the second height; and a first select line arranged to drive only the first row of pixels and a second select lines spaced from the first select line arranged to drive only the second row of pixels wherein the emitting areas of the first and second pixels are disposed between the first and second select lines.
1. An active matrix OLED display having pixels with light emitting areas arranged in rows and columns comprising;
(a) a first pixel disposed in a first column of pixels and in a first row of pixels;
(b) a second pixel disposed in the first column of pixels and in a second row of pixels wherein the second row of pixels is adjacent to the first row of pixels;
(c) at least a third pixel disposed in a second column of pixels and in the first or second row of pixels wherein the second column of pixels is adjacent to the first column of pixels; and
(d) first and second spaced select lines, first and second spaced data lines, and first and second spaced power lines arranged to drive the first, second and third pixels wherein the emitting areas of the first, second and third pixels are disposed between the first and second select lines, between the first and second data lines, and between the first and second power lines.
2. The active matrix OLED display of claim 1 wherein the first, second, and third pixels have different colors.
3. The active matrix OLED display of claim 1 wherein the emitting areas of at least two of the first, second, and third pixels have different sizes.
4. The active matrix OLED display of claim 1 wherein the first and second select lines, the first and second power lines, and the first and second data lines are linear.
5. The active matrix OLED display of claim 1 wherein the OLED display is bottom emitting.
6. The active matrix OLED display of claim 1 further including a fourth pixel disposed in the second column of pixels wherein the third pixel is disposed in the first row of pixels and the fourth pixel is disposed in the second row of pixels.
7. The active matrix OLED display of claim 6 wherein the first, second, third, and fourth pixels all have different emitting areas.
8. The active matrix OLED display of claim 6 wherein the pixels are red, green, blue and white.
