Functional Description
Screen Size
Number of horizontal pixels:
120, 240, 360, 600, and 720 in monodirectional connection mode
240, 480, and 720 in bidirectional connection mode
Number of vertical pixels:
240 in single-rate sequential drive mode
480 in double-rate sequential drive mode
Single-Rate Sequential Drive Mode and Double-Rate Sequential Drive Mode
Single-Rate Sequential Drive Mode:
A typical TV signal* has 525 scanning lines, 480 of which are part
of the valid display period. In interlace scanning mode, 480 scanning lines are equally divided into a first
field and a second field.
In single-rate sequential drive mode, a 240-pixel-high LCD panel is used. 240 scanning lines of the first
and second fields of the TV signal are respectively assigned to the 240 lines of the LCD panel.
One line of an LCD panel is driven every horizontal scanning period in this mode.
Double-Rate Sequential Drive Mode:
To obtain a high-resolution display, a 480-pixel-high LCD panel
is used. If 480 scanning lines are respectively assigned to the 480 lines of the LCD panel, the LCD
alternating frequency becomes 15 Hz, which causes flickering and degrades display quality. To avoid this
problem, the following method is employed. In the first field, the first scanning line is assigned to the
first and second lines of the LCD panel, the second scanning line is assigned to the third and fourth lines,
and so on. In the second field, the first scanning line is assigned to the second and third lines, the second
scanning line is assigned to the fourth and fifth lines, and so on.
Two lines of an LCD panel are driven every horizontal scanning period in this mode.
Note: *Refer to the index for the further information of NTSC TV system signals and LCD.
