Appeal No. 96-1855
Application 07/953,807
For each embodiment, halftones need not be halfway
between white and black. Appellants' figure 26 illustrates
display data for 16 tones, having 14 different shades between
white and black. Increasing the number of tones requires a
commensurate increase in the number of frames used for each
tone.
Representative claim 1 is reproduced as follows:
1. A liquid-crystal halftone display system
comprising:
a data driver which receives liquid-crystal display
data corresponding to input display data representing any of
display-ON, display-OFF and a halftone display for each of a
plurality of pixels for one line, and which outputs said
liquid-crystal display data for one line as horizontal display
data;
a scan driver which designates a line of a liquid-
crystal panel for displaying said horizontal display data;
a liquid-crystal panel which displays said
horizontal display data as visible information on the line
designated by said scan driver;
a line memory in which the input display data is
stored for at least one line; and
halftone pattern generating means for generating
said liquid-crystal display data to be received by said data
driver by the use of contents of said line memory and the
input display data;
