HP in:
VCC 5 V (pulse VCC /pin 44)
HP pulse input pin
• Input threshold voltage: 1.4 V

• Does BLK on the RGB output at input = high
High input: V47 ≥ 2.1 V
5 V
0 V
Low input: V47 ≤ 0.9 V
• The auto cutoff timing pulse is generated by
HP pulse.

• The data for color, tint, brightness and
contrast will be re-written at the time when
VP pulse goes high to low. But at DAC SW
(V-latch Mode): In the through mode, the
data will be rewritten according to the timing
sent, regardless of VP pulse.

• Auto cutoff timing pulse will be generated
according to VP pulse.

• Be sure to keep the VP pulse width more
than 6H.
• Recommended use range: 0 V to 5 V
