DB3+/-, CKB+/-) and TxSEL signal must be "0" voltage, exclude the VALID period (See
above sequence diagram). If these signals are higher than 0.3V, the internal circuit 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. VDD should be cut when
the display and function signals are stopped.
