exclude the VALID period (See above sequence diagram), in order to avoid that internal
circuits is damaged.
If some of display and function signals of this product are cut while this product is
working, even if the signal input to it once again, it might not work normally. If customer
stops the display and function signals, they should be cut VDD.
* These signals should be measured at the terminal of 100 resistor.
