General Descriptions
NT39211 is a dedicated gate driver IC for TFT-LCD panels. After a start pulse is triggered, channel outputs pins
will sequentially output high-driving voltage pulses as the gate signals on TFT-LCD panels. NT39211 also
provides shift up/down selection and cascade functions for dot expansion. The special pin location is designed for
COG type.

Description
XONR,
XONL
I
When XON goes low, all outputs are fixed to VGG. A 200k ohm pull-up resistor
is connected between this pin and VCC. XON signal has priority over OE1/2/3.
These pads are shorted internally, active high.
OE1R, OE1L
I
When this pin is applied to “H”, the (3n+1)th channel outputs, n=0, 1, 2, …199,
are disabled (=VEE). This condition will not affect the operation of the internal
registers. OE1 control signal is independent with the CLK.
These pads are shorted internally, active high.
OE2R, OE2L
I
When this pin is applied to “H”, the (3n+2)th channel outputs, n=0, 1, 2, …199,
are disabled (=VEE). This condition will not affect the operation of the internal
registers. OE2 control signal is independent with the CLK.
These pads are shorted internally, active high.
OE3R, OE3L
I
When this pin is applied to “H”, the (3n+3)th channel outputs, n=0, 1, 2, …199,
are disabled (=VEE). This condition will not affect the operation of the internal
registers. OE3 control signal is independent with the CLK.

Shift up/down control signal
I U_D = “H”, up shift: STVD (Input) G1 ~ G600 STVU (Output)
U_D = “L”, down shift: STVU (Input) G600 ~ G1 STVD (Output)
I Shift clock signal for internal shift register

This pin operates as an input pin under the condition of U_D = ”H” and receives
I/O
a pulse signal; this pin operates as an output pin under the condition of
U_D=”L” and send a pulse signal.
Please refer to the descriptions of “STVU” and “U_D”.
P Positive power supply for G1 ~ G600 outputs
P Negative power supply for G0 ~ G601 outputs
P Power supply for digital circuits
P Ground
This pin operates as an input pin under the condition of U_D = ”L” and receives
I/O
a pulse signal; this pin operates as an output pin under the condition of
U_D=”H” and send a pulse signal.
Please refer to the descriptions of “STVD” and “U_D”.
G1 ~ G600
Pulse signals for driving the gates on TFT-LCD
O VGG minus VEE is the amplitude of G1 ~ G600. The timing of G1 ~ G600 is
synchronous with the rising edge of the shift clock CLK.
G0, G601
O
Auxiliary pins. Regardless of shift data, G0 and G601 always output the
potential of VEE.
Note: I: Input; O: Output; I/O: Input/Output; P: Power; S: Shorted line.
