Example of Application
In this example, two HD61203s output the equivalent waveforms. So, stand-alone operation is possible.
In this case, connect COM1 and COM65 to X1, COM2 and COM66 to X2, ..., and COM64 and COM128
to X64. However, for the large screen display, it is better to drive in 2 rows as in this example to
guarantee the display quality.
