Signal Name
Quantity
Input/Output
Function
FRM
1
Input
Input frame synchronous signal.
Frame synchronous signal FRM is identified by the rising
edge of the CL1 signal, which triggers offset cancellation.
Normal dot-inversion is performed for the first or second
frame. Polarity of the voltage dispersion of the output pins is
inverted for the third or fourth frame. The voltage dispersion
applied to each pixel is cancelled using four-frame cycles,
enabling high-quality displays. (Offset cancellation between
frames)
The FRM pin is pulled down (to about 50 k
) in the chip.
When the above function is not used, the FRM pin can be
opened.
LC
1
Input
Fix high when the offset cancellation function between
raster-rows is used. Polarity of voltage dispersion of the
output pins is inverted by each two raster-rows, and the
voltage dispersion applied to each pixel is cancelled,
enabling high-quality displays.
The LC pin is pulled down (to about 50 k
) in the chip.
When the above function is not used, the LC pin can be
opened.
The operation to combine the FRM pin and the LC pin is as
follows:
Open (pull-down)
Only cancellation between
raster-rows*
Frame-synchronous signal

Cancellation between
frames and raster-rows
Only cancellation between

No cancellation

Open
(pull-down)
TESTOUT
Note:
1
Output
Output pin for test signal. Leave open.
Cancellation between raster-rows is most effective when combining cancellation between
frames. It is recommended that cancellations between frames and between raster-rows be used
together.
