Abstract
Abstract A high definition display having a display line pitch smaller than a cell arrangement pitch in the column direction is disclosed. A display device to be used has a display surface including plural cell columns, each of which is a set of cells having the same light emission color. The display device has a cell arrangement structure in which cell positions in the column direction are shifted from each other between the neighboring cell columns. An interlaced display is performed by changing the combination of cells of a display line that is perpendicular to the column direction in every field between the neighboring cell columns of the same light emission color. <IMAGE>

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
98 words
A method of displaying an image, comprising the
steps of: using a display device having a display surface
including plural cell columns each of which is a set of cells
having the same light emission color, the display device
having a cell arrangement structure in which cell positions in
the column direction are shifted from each other between the
neighboring cell columns; and performing an interlaced display by changing the
combination of cells of a display line that is perpendicular
to the column direction in every field between the neighboring
cell columns of the same light emission color.
Claim 2
Dependent Claim
69 words
The method according to claim 1, further comprising
the step of determining luminance of each cell of the display
surface by distributing a luminance value of each pixel of an
input image to be displayed to cells corresponding to pixels
in accordance with the cell position relationship between a
virtual display surface having a cell arrangement
corresponding to a pixel arrangement of the input image and
the display surface.
Claim 3
Dependent Claim
98 words
A display apparatus comprising: a display device having a display surface including
plural cell columns each of which is a set of cells having the
same light emission color, the display device having a cell
arrangement structure in which cell positions in the column
direction are shifted from each other between the neighboring
cell columns; and a driving circuit for performing an interlaced display by
changing the combination of cells of a display line that is
perpendicular to the column direction in every field between
the neighboring cell columns of the same light emission color
in every field.
Claim 4
Dependent Claim
51 words
The display apparatus according to claim 3, wherein
the cells are arranged at a constant pitch in each cell column
and the shift quantity of the cell position in the column
direction between the neighboring cell columns of the same
light emission color is a half of the cell arrangement pitch.
Claim 5
Dependent Claim
69 words
The display apparatus according to claim 3 or 4, wherein
luminance of each cell of the display surface is determined by
distributing a luminance value of each pixel of an input image
to be displayed to cells corresponding to pixels in accordance
with the cell position relationship between a virtual display
surface having a cell arrangement corresponding to a pixel
arrangement of the input image and the display surface.
Claim 6
Dependent Claim
24 words
The display apparatus according to claim 3, 4 or 5 wherein
the all cells within the display surface have the same light
emission color.
Claim 7
Dependent Claim
42 words
The display apparatus according to claim 3, 4 or 5, wherein
the display surface includes three kinds of cell columns
having different light emission colors, and the color
arrangement has a pattern in which three colors are repeated
in a constant order.
Claim 8
Dependent Claim
38 words
The display apparatus according to any of claims 3 to 7, wherein
an interlaced image to be displayed is inputted, and the
direction of the display line is the direction of a scanning
line of the interlaced image.
Claim 9
Dependent Claim
33 words
The display apparatus according to any of claims 3 to 7, wherein
a non-interlaced image to be displayed is inputted, and the
non-interlaced image is converted into an interlaced image to
be displayed.
Claim 10
Dependent Claim
24 words
The display apparatus according to claim 9, wherein
gradation data of each pixel of the interlaced image are
generated from the non-interlaced image data.
Claim 11
Dependent Claim
20 words
The display apparatus according to any of claims 3 to 10, wherein
the display device is a plasma display panel.
Claim 12
Dependent Claim
75 words
The display apparatus according to any of claims 3 to 11, wherein
the display device is a plasma display panel having an inner
structure including a partition for dividing a discharge space
for each cell column, the discharge space is continuous over
the entire length of the display surface in each cell column,
and wide portions and narrow portions are arranged alternately
so that the narrow portion is located at the boundary position
between cells.
Claim 13
Dependent Claim
35 words
The display apparatus according to claim 12, wherein
the display device has a plurality of scanning electrodes
arranged to straddle over all cell columns for selecting one
cell in each cell column of each field.
