Blink Mark Display
The HD66724/HD66725 have a grayscale display and blink display based on 144 (192) individual
segments (marks). Forty-eight (sixty-four) of these are for grayscale display and the remainder are for
blink display.
These 48 (64) segments can also control a grayscale display, providing simple grayscale on specific
pictograms or marks. For example, the battery no charge alarm uses this dispay. The above display uses a
curtailed frame grayscale system, and flicker may result in quick-response liquid crystal materials. Tables
42 and 43 show the relationship between set data in SEGRAM and effective applied voltage during frame
curtailing operation.
The remaining 96 (128) segments are resposible for normal blinking and double-speed blinking. Normal
blinking (b & w) is achieved by repeatedly turning on each segment for 32 frames and turning it off for the
next 32 frames. Double-speed blinking (b & w) is achieved by repeatedly turning on each segment for 16
frames and turning it off for the next 16 frames, that is, double the speed of normal blinking.
