∗1 Video input signal shall be symmetrical to VVC.
∗2 The optimum typical value of the common pad voltage may lower its suitable voltage according to the set
construction to use. In this case, use the voltage of which has maximum contrast as typical value. When the
typical value is lowered, the maximum and minimum values may lower.
∗3 Input a uniformity improvement signals PSIGR, PSIGG and PSIGB in the same polarity with video signals
SIGR1 to 6, SIGG1 to 6 and SIGB1 to 6 and which is symmetrical to VVC. PSIGR, PSIGG and PSIGB have
two steps as shown by the waveform in the figure below, and in the table above, the upper value indicates
the signal level of the first step, and the lower value, the signal level of the second step.
Here, the rising and falling of PSIGR, PSIGG and PSIGB are synchronized with the rising of PCG pulse,
and the rise and fall times trPSIGR, trPSIGG, trPSIGB, tfPSIGR, tfPSIGG and tfPSIGB are suppressed
within 800ns.

LCX020BK level conversion circuit
The LCX020BK has a built-in level conversion circuit in the clock input unit on the panel. The input signal level
increases to HVDD or VVDD. The Vcc of external ICs are applicable to 5 ± 0.5V.
