FSTN panel composed of 128 segments and 64 commons. The LCM can be easily
accessed by micro controller via serial interface.The input signal rise
and fall time (tr, tf) are specified at 15 ns or less. All timing is
specified using 20% and 80% of VDD as the standard.
3. Usually, the files used by the device are saved in the appointed folders
to ensure the access for embedded program of the device. You may save files

4. Instruction Setup:
With this IC,when the power is applied,LCD driving
non-selective potentials V2 and V3 and V1 and V4 are output through the
LCD driving output pins SEG and COM.When electric charge is remaining in
the smoothing capacitor connecting between the LCD driving voltageoutput
pin(V1~V5) and the VDD pin,the picture on the display may become totally
dark instantaneously ehwn the power is turned on.To avoid occurrence of
such a failure,we recommend the fllowing flow when turning on the power.
