64 gray level voltages on each output. Output voltages are
driven with individual high drive, low offset operational amplifiers. Data loading and line buffering is accomplished by
means of an internal, bi-directional shift register.
Functional Description
GENERAL OVERVIEW
The FPD33684 is a low power, low EMI, 384 output column
driver with 64 gray level capability (6-bit). It provides direct
drive for TFT-LCD displays, eliminating the need for Vcom
modulation. Direct drive significantly reduces system power
consumption and also reduces component count while providing superior image quality and cross-talk margin. The
FPD33684 utilizes National’s Charge Conservation Technology that recovers energy stored in the capacitance of the
column lines to reduce power consumption further.
The FPD33684 is designed for use in systems using dot
inversion as the method of polarity inversion. Column inversion and N-line inversion are also supported. Other modes of
polarity inversion including line inversion and frame inversion
are not supported.
Digital video data inputs to the FPD33684 are received via a
low power, low EMI Reduced Swing Differential Signaling
(RSDS™) bus. The RSDS™ digital video commands one of
GAMMA CORRECTION
The FPD33684 is designed to offer compatibility with a wide
range of panel gamma characteristics. The output voltage is
controlled by the digital data on the RSDS™ bus. Two identical R-DACs are used to program the output voltages. One
R-DAC provides the high-polarity output voltages (voltages
higher than Vcom) and the other provides the low-polarity
output voltages (voltages lower than Vcom).
The FPD33684 is available with two R-DAC resistance curve
options, both of which have been carefully designed to accurately match the natural, inverse gamma of a twisted
nematic (TN) display with a 2.2 gamma transfer characteristic. A typical TN display, when operated with the FPD33684
drivers will produce a luminance with grayscale characteristics typical of CRT monitors. The R-DAC resistance values
for the FPD33684A are shown in Figure 3 and Figure 4. The

VCSTIME,will then decay toward GND at a rate determined by
the RCSTIME and CCSTIME time constant. When VCSTIME
reaches VDD1/2 the output mode switches from charge sharing to conventional amplifier drive mode. The charge-share
mode time can be calculated using the following equation:
tcharge-share = 0.69 x RCSTIME x CCSTIME
(Continued)
R-DAC resistance values for the FPD33684B (designed to
match the gamma curve of the Samsung S6C0666) are
shown in Figure 5 and Figure 6. Most applications will only
need to provide references for each of the two ends of the
two R-DACs (GMA1, GMA5, GMA6, and GMA10). Six additional, intemediate R-DAC tap points are available for further
customization.
RSDS™ DATA CHANNEL
The RSDS™ data bus is comprised of nine differential data
pairs and a differential clock. The nine channels are organized as three busses of three channels each. Each three
channel bus corresponds on one of the three video colors,
red, green and blue. Because the clocking is dual edged, the
even fields of the 6-bit word are transmitted-received on a
first clock and are followed by the odd fields. One full pixel
(red, green, and blue subpixels) is transmitted every full
pixelclock cycle.
CHARGE CONSERVATION TECHNOLOGY
National Semiconductor’s proprietary charge conservation
technology significantly reduces power consumption.
Charge conservation works by briefly switching all of the
columns at the start of each line to a common node. This has
the effect of redistributing the charge stored in the capacitance of the panel columns. Because half the columns are at
voltages more positive than Vcom and half are more negative, this redistribution of charge or “charge-sharing” has the
effect of pulling all of the columns to a neutral voltage near
the middle of the driver’s dynamic range. Thus, the voltages
on all the columns are driven approximately halfway toward
their next value with no power expended. This dramatically
reduces panel power dissipation (up to a theoretical limit of
50%) compared to conventional drivers which must drive
each column through the entire voltage swing every time
polarity is reversed.
’Smart’ charge sharing is used to further optimize this feature. Data inversion is monitored and charge shared only
across data ranges (when output polarity changes between
adjacent lines). This is useful during n-line inversion when
polarity changes do not occur at every line transition.
Charge sharing enables the FPD33684 to have faster output
rise and fall times than drivers with convential amplifiers.
This is due to the fact that the instantaneous currents supplied by the energy stored in the panel are much higher than
the maximum output current of conventional drivers.
CSTIME — CHARGE SHARE TIME
OPTIONAL LINE BUFFERS
The FPD33684 provides two general purpose, unity gain
output buffers, one located at each end of the input bank of
the die. These buffers may be used to repair an open column
line. The drive signal from the output of the faulted line can
be stitched to the input of the repair buffer during the repair
process. The output of the repair buffer is then routed to the
other side of the column line making it possible to maintain
fast rise and fall times on both ends of the afflicted column
line.
PIN DESCRIPTIONS
The pin order configuration for the FPD33684 is shown in
Figure 7. Optional pins do not need to be carried off a
custom TCP or COF package but may require a connection
to a neighboring pad on the die by a tie on the tape.
CLKP and CLKN — DATA CLOCK (INPUT)
Differential clock input for RSDS™ data loading.
D00P–D22N — RSDS™ DATA BUS (INPUT)

Where x = 0 (LSB), 1 or 2 (MSB).
ENIO1/ENIO2 — DATA LOADING ENABLE 1 AND 2 (I/O)
The CSTIME pin allows the user to set the duration of
charge-sharing mode based on the panel capacitance and
resistance. The length of charge-sharing is important because it must be long enough to allow all of the columns to
equalize to the same value in order to achieve optimum
power performance. The length of charge-mode is user programmable. There are two common methods to drive the
CSTIME pin.
The first method is to actively drive the CSTIME input with a
control signal. This may be achieved by connecting the
LOAD signal to the CSTIME input.The width of the
LOAD/CSTIME signal determines the amount of time spent
in charge-sharing. This width may be optimized for a particular panel load. A ’typical’ width is 800ns. If desired, the
CSTIME pin may be driven independently, however, this will
require an additional output from the timing controller.
At the rising edge of the CSTIME/LOAD input signal, the
outputs enter charge-sharing mode. Outputs remain in
charge-mode until the falling edge of the CSTIME/LOAD
signal.
A second method for setting charge-time is to connect a
resistor (RCSTIME) and capacitor (CCSTIME) in parallel between the CSTIME pin and ground. Only one resistor and
capacitor is required for the entire display. At the rising edge
of the LOAD signal, the CSTIME pin is internally pulled to
VDD1 and then released (i.e. floated). At this time the outputs
enter charge-sharing mode. The voltage on the CSTIME pin,
www.national.com
The ENIO1/ ENIO2 pins are used to daisy chain the
FPD33684 together with other FPD33684s. The first input in
the chain is normally connected to the SP signal (or it’s
equivalent) on the timing controller. If UP = H, then the
ENIO1 pin is configured as an input and the ENIO2 pin is
configured as an output. If UP = L, then the ENIO2 pin is
configured as an input and the ENIO1 pin is configured as an
output.
INVERT — DIGITAL DATA INVERT (INPUT)
When INVERT = H, RSDS data is inverted. The INVERT pin
can be tied either high or low through connection to a neighboring pin, eliminating the need to bring the pin off the
package.
LOAD — DATA LOAD (INPUT)
The rising edge of LOAD copies the digital video buffered by
the shift register into a second latch for conversion to analog.
The outputs are forced into charge share mode while load is
high. When CSTIME = LOAD the falling edge ends the
charge share time and the newly converted analog voltages
are driven by the outputs.
POL — POLARITY (INPUT)
8
The CSTIME pin allows the user to set the duration of
charge-sharing mode based on the panel capacitance and
resistance.
VDD1 — DIGITAL VOLTAGE SUPPLY
(Continued)
When POL = L, odd numbered outputs (1, 3, 5, ...383) are
controlled by VGMA6 through VGMA10 and even numbered
outputs are controlled by VGMA1 through VGMA5. When
POL = H, odd numbered outputs are controlled by VGMA1
through VGMA5 and even numbered outputs are controlled
by VGMA6 through VGMA10.
Positive supply voltage for the digital logic functions of the
driver.
VDD2 — ANALOG VOLTAGE SUPPLY
Positive supply voltage for the analog functions of the driver.
VGMA1–VGMA10 — RDAC REFERENCES (INPUTS)
RPI1/ RPI2 — REPAIR INPUT 1 AND 2 (INPUT)
The input signal for the repair line buffers. These buffers are
optional and when not used, the input should be tied to
ground. The pin can be tied to ground through a local pin on
the TCP, eliminating the need to bring the repair amp inputs
or outputs off the TCP.
The reference voltages to the upper and lower RDACs used
to control the inverse gamma transfer function of the driver.
Option - Any or all of the inputs VGMA2 through VGMA4 and
VGMA7 through VGMA9 can be left undriven (floating).
VHBIAS — HIGH BIAS CURRENT VOLTAGE SUPPLY
RPO1/ RPO2 — REPAIR OUTPUT 1 AND 2 (OUTPUT)
The output of the repair line buffers. These outputs are
current buffered copies of their respective inputs.
UP — DATA SHIFT DIRECTION — UP OR DOWN (INPUT)
Optional positive supply voltage that provides a constant
bias current to the output amplifiers to extend dynamic
range. When separately provided, VHBIAS must be 1.5V
greater than VGMA1. When not separately provided, VHBIAS
must be tied to VDD2. In this configuration, VGMA1 must be
held at or below VDD2 −1.5V.
VSS1 — DIGITAL GROUND
Digital ground reference voltage.
VSS2 — ANALOG GROUND
Analog ground reference voltage.
The UP pin controls the data shift direction. If UP is high then
data is shifted “up” from output 1 to output 384, ENIO1 is
configured as an input, and ENIO2 is an output. If UP is low
then data is shifted “down” from output 384 to output 1,
ENIO2 is an input, and ENIO1 is an output. The UP pin can
be tied either high or low through connection to a neighboring pin, eliminating the need to bring the pin off the package.
