Blink Mark Display
The HD66732 has a grayscale display and blink display based on 200 individual segments (marks). Forty
of these are for grayscale display and the remainder are for blink display.
These 40 segments can also control the grayscale display, providing simple grayscale on specific
pictograms or marks. The above display uses a curtailed frame grayscale system, and flicker may result in
quick-response liquid crystal materials. Table 57 shows the relationship between set data in the SEGRAM
and the effective applied voltage during the frame curtailing operation. These grayscale control segments
are driven with the same grayscale data when COMS1 and COMS2 are selected.
The remaining 160 segments are responsible for normal blinking and double-speed blinking. Normal
blinking (black and white) is achieved by repeatedly turning on each segment for 32 frames and turning it
off for the next 32 frames. Double-speed blinking (black and white) is achieved by repeatedly turning each
segment on and off every 16 frames. These blinking control segments are driven by the independent
blinking data when COMS1 and COMS2 are selected.
