LCX027AKB
1.4cm (0.55-inch) NTSC/PAL Color LCD Panel
For the availability of this product, please contact the sales office.
Description
The LCX027AKB is a 1.4cm diagonal active matrix
TFT-LCD panel addressed by 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 (0.55-inch; 1.397cm in diagonal)
• Horizontal resolution: 400 TV lines
• High optical transmittance: 4.2% (typ.)
• High contrast ratio with normally white mode: 200 (typ.)
• Built-in H and V drivers (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
• 4:3 and 16:9 aspect switching function
Element Structure
• Dots
Total dots : 827 (H) × 228 (V) = 188,556
Active dots: 800 (H) × 225 (V) = 180,000
• Built-in peripheral driver using polycrystalline silicon super thin film transistors.
Applications
• Viewfinders
• Super compact liquid crystal monitors etc.

LCX027AKB
Level Conversion Circuit
The LCX027AKB has a built-in level conversion circuit in the clock input unit located inside the panel. The
circuit voltage is stepped up to VDD inside the panel. This level conversion circuit meets the specifications of a
3.0V power supply of the externally-driven 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 VDD voltage.
The Vth values under standard conditions are
indicated in the table below. (HST, VST, EN, CLR,
RGT, VCK and BLK 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
Example of differential I/O
characteristics
Input voltage [V]
A slight pull-in current is generated at the input pin
of the level conversion circuit. (The equivalent
circuit 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. (Refer
to electrical characteristics.)
