Abstract
Abstract An improved method of arrangement for the cells comprising the pixels of a display device wherein each of the pixels includes a brightest cell, a bright cell, a medium cell and a dark cell. The brightest cell and the bright cell are aligned substantially parallel to one the display axes and the bright cell and the dark cell are diagonally aligned with respect to the axes of the dipslay.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
A method for producing straight vertical and horizontal alpha-numeric lines and for producing upwardly and downwardly sloping alpha-numeric lines having the same overall appearance in a display device having an array of multi-cell pixels arranged along horizontal and vertical axes, wherein each of said pixels includes a white cell, a green cell, a red cell and a blue cell comprising the steps of: arranging said white cell and said green cell substantially parallel to one of said axes; and aligning said green cell and said blue cell diagonally with respect to the other of said axes.
Claim 2
Independent Claim
96 words
A method for producing straight vertical and horizontal alpha-numeric lines and for producing upwardly and downwardly sloping alpha-numeric lines having the same overall appearance in a display device having an array of multi-cell pixels arranged along horizontal and vertical axes, wherein each of said pixels includes a white cell, a green cell, a red cell and a blue cell comprising the steps of: arranging said white cell and said green cell substantially parallel to one of said axes; and aligning said green cell and said blue cell diagonally with respect to the other of said axes.
Claim 3
Dependent Claim
16 words
The method of claim 1 further including the step of operating said cells as bilevel devices.
Claim 4
Independent Claim
98 words
A method for producing straight vertical and horizontal alpha-numeric lines and for producing upwardly and downwardly sloping alpha-numeric lines having the same overall appearance in a display device having an array of multi-cell liquid crystal pixels arranged along horizontal and vertical axes, wherein each of said pixels includes a white cell, a green cell, a red cell and a blue cell comprising the steps of: arranging said white cell and said green cell substantially parallel to one of said axes; and aligning said green cell and said blue cell diagonally with respect to the other of said axes.
Claim 5
Independent Claim
