µPD16634A
300-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64 GRAY SCALE)
DESCRIPTION
The µPD16634A is a source driver for TFT-LCDs capable of dealing with displays 64 gray scales. Data input is
based on digital input configured as 6 bits by 6 dots (2 pixels), which can realize a full-color display of 260,000 colors
by output of 64 values γ -corrected by an internal D/A converter and 5-by-2 external power modules. Because the
★
output dynamic range is as large as VSS2+0.1 V to VDD2−0.1 V, level inversion operation of the LCD’s common
electrode is rendered unnecessary. Also to be able to deal with dot-line inversion when mounted on a single side,
this source driver equipped with a built-in 6-bit D/A converter circuit whose odd output pins and even output pins
respectively output gray scale voltages of differing polarity. Assuring a maximum clock frequent of 40 MHz when
drivng at 3.0 V, this driver is applicable to XGA-standard TFT-LCD panels.
FEATURES

This figure does not specify the TCP package. Therefore POL2 pins can be reduced by
opening or short-circuiting to VSS2 by TCP wiring. POL2 pin can short to VSS1 on TCP.
So when you not use “data inversion function”, can reduce input pins.

These refer to the start pulse input/output pins when cascades are
connected. The shift directions of the shift registers are as follows.
R,/L = H : STHR input, S1→S300, STHL output
R,/L = L : STHL input, S300→S1, STHR output
R,/L = H : Becomes the start pulse input pin.
R,/L = L : Becomes the start pulse output pin.
R,/L = H : Becomes the start pulse input pin.
R,/L = L : Becomes the start pulse output pin.
Refers to the shift register’s shift clock input. The display data is
incorporated into the data register at the rising edge. At the rising edge of
the 50th clock after the start pulse input, the start pulse output reaches the
high level, thus becoming the start pulse of the next-level driver. The initiallevel driver’s 50th clock becomes valid as the next-level driver’s start pulse
is input. If 52 clock pulses are input after input of the start pulse, input of
display data is halted automatically. The contents of the shift register are
cleared at the STB’s rising edge.
The contents of the data register are transferred to the latch at the rising
edge. And, at the falling edge, the gray scale voltage is supplied to the
driver. It is necessary to ensure input of one pulse per horizontal period.
POL = L ; The S2n-1 output uses V0 to V4 as the reference supply; and the S2n
output uses V5 to V9 as the reference supply.
POL = H ; The S2n-1 output uses V5 to V9 as the reference supply; and the
S2n output uses V0 to V4 as the reference supply.
S2n-1 indicates the odd output; and S2n indicates the even output. Input of
the POL signal is allowed the setup time (tPOL-STB) with respect to STB’s
rising edge.
POL2 = H : Display data is inverted.
POL2 = L : Display data is not inverted.
Input the γ-corrected power supplies from outside by using operational
amplifier. Make sure to maintain the following relationships. During the gray
scale voltage output, be sure to keep the gray scale level power supply at a
constant level.
VDD2 > V0 > V1 > V2 > V3 > V4 > V5 > V6 > V7 > V8 > V9 > VSS2

Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0 to V9 in that order. Reverse
this sequence to shut down.(Simultaneous power application to VDD2 and V0 to V9 is possible.)
2. To stabilize the supply voltage, please be sure to insert 0.1 µF bypass capacitor between
VDD1-VSS1 and VDD2-VSS2. Furthermore, for increase precision of the D/A converter, insertion of a
bypass capacitor of about 0.01 µF is also advised between the γ-corrected power supply
terminals(V0,V1,V2...,V9) and VSS2.
3. We recommend to use Operational Amplifier to lower input impedance of γ-corrected voltage.

5. RELATIONHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE
This product incorporates a 6-bit D/A converter whose odd output pins and even output pins output respectively gray
scale voltages of differing polarity with respect to the LCD’s counter electrode (common electrode) voltage. The D/A
converter consists of ladder resistors and switches. The ladder resistors r0 to r62 are so designed that the ratios
between the LCD panel’s γ-corrected voltages and V0’ to V63’, V0” to V63” are roughly equal; and their respective
resistance values are as shown in Table 6-1. Among the 5-by 2 γ-corrected voltages, input gray scale voltages of the
same polarity with respect to the common voltage, for the respective five γ-corrected voltages of V0 to V4 and V5 to
V9. If fine gray scale voltage precision is not necessary, the voltage follower circuit supplied to the γ-corrected power
supplies V1 to V3 and V6 to V8 can be deleted.
Figure 5-1 shows the relationship between the driving voltages such as liquid-crystal driving voltages VDD2 and VSS2,
common electrode potential VCOM, and γ-corrected voltages V0 to V9 and the input data. Be sure to maintain the
voltage relationships of VDD2 > V0 > V1 > V2 > V3 > V4 > V5 > V6 > V7 > V8 > V9 > VSS2. Figure 6-1 and 6-2 show the
relationship between the input data and the output data.
This driver IC is designed for single-sided mounting. Therefore, please do not use it for γ-corrected power supply
level inversion in double-sided mounting.

9. CAUTIONS ABOUT FRAME INVERSION
In the case of dot inversion, n frame last line and (n+1) frame first line is the same polarity. When write the same
polarity twice; there are two cases as follows.
(1) Last line output in n frame > First line output in (n+1) frame → Positive to write
(2) Last line output in n frame < First line output in (n+1) frame → Not possible to write
µPD16634A has charge buffer and discharge buffer, so need to inversion polarity and write in the case of both
ways.

Notes 1. VX refers to the output voltage of analog output pins S1 to S300.
VOUT refers to the voltage applied to analog output pins S1 to S300.
2. The output voltage deviation refers to the voltage difference between adjoining output pins when the
display data is the same (within the chip).
3. The average output voltage variation refers to the average output voltage difference between chips. The
average output voltage refers to the average voltage between chips when the display data is the same.
4. The STB cycle is defined to be 20 µs at fCLK = 40 MHz. The TYP. values refer to an all black or all white
input pattern. The MAX. value refers to the measured values in the dot checkerboard input pattern.
5. Refers to the current consumption per driver when cascades are connected under the assumption of
SVGA single-sided mounting (10 units).

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.

HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.

STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.

• While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
• NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
