Description
VBS
I
Reference voltage for step-up circuit3.
REGN,
REGP
I/O
Input pins for reference voltages of VREG1OUT, and VREG2OUT when the internal
reference-voltage generation circuit is not used. Leave these pins open when the internal
reference-voltage generation circuit is used.
VREG1OUT
O
This pin outputs a reference voltage for VREG1 between AVDD and VSS. When the
internal reference voltage is not used, the reference voltage can be generated from the
voltage of REGP. Connect this pin to VREG1 and a capacitor for stabilization. When this
pin is not used, leave it open.
VREG2OUT
O
This pin outputs a reference voltage for VREG2 between VSS and VGL When the internal
reference voltage is not used, the reference voltage can be generated from the voltage of
REGN. Connect this pin to VREG2 and a capacitor for stabilizatio0n. When this pin is not
used, leave it open.
VcomOUT
O
A power supply for the TFT-display counter electrode.
The alternating cycle can be set by the M pin. Connect this pin to the TFT-display counter
electrode.
This pin is also used as equalizing function: When EQ = “High” period, all source driver’ s
outputs (S1 to S396) are short to Vcom level (Hi-z). In case of VcomL < 0V, equalizing
function must not be used. (Set EQ bit (R07h) to be “00” for preventing the abnormal
function.)
VcomR
I
A reference voltage of VcomH.
When VcomH is externally adjusted, halt the internal adjuster of VcomH by setting the
register and insert a variable resistor between GVDD and VSS. When this pin is not
externally adjusted, leave it open and adjust VcomH by setting the internal register.
VcomH
O
This pin indicates a high level of Vcom generated in driving the Vcom alternation.
Connect this pin to the capacitor for stabilization.
VcomL
O
When the Vcom alternation is driven, this pin indicates a low level of Vcom. An internal
register can be used to adjust the voltage. Connect this pin to a capacitor for stabilization.
When the VCOMG bit is low, the VcomL output stops and a capacitor for stabilization is not
needed.
VGH
O/
Power
A positive power output pin for gate driver, internal step-up circuits, bias circuits, and
operational amplifiers. Connect a capacitor for stabilization.
Interconnect this pin to VCI3 pin.
VGL
O/
Power
A Negative power output pin for gate driver, bias circuits, and operational amplifiers.
Connect a capacitor for stabilization. When internal VGL generator is not used, connect an
external-voltage power supply higher than -15.0 V.
