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.
