Description
The LCX009AK is a 1.8cm diagonal active matrix
TFT-LCD panel addressed by the polycrystalline
silicon super thin film transistors with built-in
peripheral driving circuit. This panel provides full-
color representation in NTSC/PAL mode. RGB dots
are arranged in a delta pattern featuring high picture
quality of no fixed color patterns, which is inherent in
vertical stripes and mosaic pattern arrangements.
Features
The number of active dots: 180,000 (0.7-inch; 1.8cm in diagonal)
Horizontal resolution: 400 TV lines
High optical transmittance: 3.5% (typ.)
High contrast ratio with normally white mode: 200 (typ.)
Built-in H and V driving circuit (built-in input level conversion circuit, TTL drive possible)
High quality picture representation with RGB delta arranged color filters
Full-color representation
NTSC/PAL compatible
Right/left inverse display function

LCX009AK
Level Conversion Circuit
The LCX009AK has a built-in level conversion circuit in the clock input unit located inside the panel. The circuit
voltage is stepped up to 13.5V. This level conversion circuit meets the specifications of a 3.0V to 5.0V power
supply of the externally-driven IC mainly. However, this circuit can operate even with a 12V power supply of
the IC.
1. I/O characteristics of level conversion circuit
(For a single-phase input unit)
An example of the I/O voltage characteristics of a
level conversion circuit is shown in the figure to the
right. The input voltage value that becomes half the
output voltage (after voltage conversion) is defined
as Vth.
The Vth value varies depending on the HV
DD
and
VV
DD
voltages.
The Vth values under standard conditions are
indicated in the table below. (HST, VST, EN, CLR, and RGT in the case of a single-phase input)

(For a differential input unit)
An example of I/O voltage characteristics of a
level conversion circuit for a differential input is
shown in the figure to the right. Although the
characteristics, including those of the Vth voltage,
are basically the same as those for a single-
phased input, the two-phased input phase is
defined. (Refer to clock timing conditions.)

2. Current characteristics at the input pin of level
conversion circuit
A slight pull-in current is generated at the input
pin of the level conversion circuit. (The equivalent
circuit diagram is shown to the right.) The current
volume increases as the voltage at the input pin
decreases, and is maximized when the pin is
grounded.) (Electrical characteristics are defined
by the grounded input.)
