LCX007CN
3.4cm (1.35-inch) Black-and-White LCD Panel
Description
The LCX007CN is a 3.4cm diagonal active matrix
TFT-LCD panel addressed by polycrystalline silicon
super thin film transistors with built-in peripheral
driving circuit. Use of three panels in combination
with the LCX007CL provides a full-color representation.
(The LCX007CN has the visual field angle characteristics
of mirror symmetry to those of the LCX007CL.)
This panel provides a wide aspect ratio of 16:9,
such as those represented in HD. The built-in sideblack function also allows an aspect ratio of 4:3 in
the NTSC/PAL mode.
This panel has a polysilicon TFT high-speed
scanner and built-in function to display images
up/down and/or right/left inverse. The built-in 5V
interface circuit leads to lower voltage of timing
system and control signals.
Features
• The number of active dots: 512,880 (1.35-inch; 3.4cm in diagonal)
• Horizontal resolution: 600 TV lines
• High optical transmittance: 16.5% (typ.)
• High contrast ratio with normally white mode: 190 (typ.)
• Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible)
• NTSC/NTSC-WIDE/HD (band: 20MHz) mode selectable
(PAL/PAL-WIDE mode also available through conversion of scanned dot numbers by an external IC)
• Up/down and/or right/left inverse display function
• Side-black function
• 16:9 and 4:3 aspect-ratio switching function
Element Structure
• Dots
16:9 display: 1068.5 (H) × 480 (V) = 512,880
4:3 display: 799.5 (H) × 480 (V) = 383,760
• Built-in peripheral driver using polycrystalline silicon super thin film transistors.
Applications
• Liquid crystal projectors
• Super compact liquid crystal monitors
• Viewfinders etc.

L (White): Surface luminance of the TFT-LCD panel at the input signal amplitude VAC = 0.5V.
L (Black): Surface luminance of the panel at VAC = 4.5V.
Both luminosities are measured by System I.

where: V50 is the signal amplitude which gives 50% of
transmittance in V-T characteristics.
6. Image Retention Time
Image Retention time is given by following procedures.
Apply the monoscope signal to the LCD panel for 60 minutes and then change this signal to the gray scale
of Vsig = 7.0 ± VAC (VAC: 3 to 4V). Hold VAC that maximizes image retention judging by sight. Measure the
time till the residual image becomes indistinct.

2. LCD Panel Operations
[Description of basic operations]
The basic operations of the LCD panel are shown below based on the wide-display mode.
• A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse
to every 480 gate lines sequentially in every horizontal scanning period.
• A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits,
applies selected pulses to every 1068.5 signal electrodes sequentially in a single horizontal scanning period.
• Vertical and horizontal shift registers address one pixel, and then turn on Thin Film Transistors (TFTs; two
TFTs) to apply a video signal to the dot. The same procedures lead to the entire 480 x 1068.5 dots to display
a picture in a single vertical scanning period.
• The LCD pixel dots are arranged in a delta pattern, where the dots connected to the identical signal line are
positioned with 1.5-dot offset against those of the adjacent horizontal line. Horizontal Start Pulse (HST) is
generated with 1.5-bit offset between the horizontal lines to regulate the above offset. HCK and sample-hold
(S/H) pulses follow the same 1.5-bit offset scheme.
• The CLR pin is provided to eliminate the shading effect caused by the coupling of selected pulses. While
maintaining the CLR at High level, the VVDD potential drops to approximately 9.5V. This pin shall be
grounded when not in use.
• The video signal shall be input with polarity-inverted system in every horizontal cycle.
• Timing diagrams of the vertical and the horizontal display cycle are shown below:

[Description of operating mode]
The LCD panel has the following functions to easily apply to various uses, as well as various broadcasting
systems.
• Right/left inverse mode
• Up/down inverse mode
• 4:3 display mode with side-black display
These modes are controlled by three signals (RGT, DWN, and WID). The setting mode is shown below:

Up scan
Mode
The direction of the right/left and/or up/down mean when Pin 1 marking is located at right side with the pin
block upside.
• The analog signal (SID) to display side-black shall be input by 1H inversion synchronized with the signal.
3. 3-dot Simultaneous Sampling
Horizontal driver samples SIG1, SIG2 and SIG3 signal simultaneously, which requires the phase matching
between SIG1, SIG2, and SIG3 signals to prevent horizontal resolution from deteriorating. Thus phase
matching between each signal is required using an external signal delaying circuit before applying video
signal to the LCD panel.
The block diagram of the delaying procedure using sample-and-hold method is as follows.
The LCX007 has the right/left inverse function. The following phase relationship diagram indicates the phase
setting for the right scan (RGT = High level). For the left scan (RGT = Low level), the phase setting shall be
inverted between SIG2 and SIG3 signals.

Important
(1) Anti-reflection coating
Use anti-reflection coating when using a phase-shifting plate on a light egress side of the LCD to align a
polarization axis with those of a polarization screen or a prism.
(2) Direction of incident light
Allow incident light to hit upon an opposite side of a mark-indicated surface.

(3) Polarizer
This LCD is attached with a polarizer on a light egress side. A suitable heat-dissipation method shall be
incorporated to suppress optical degradation of a polarizer.
(4) Light source
• Use visible light (wavelength λ = 400 to 780nm) as a light source. Do not use a light source containing
infrared or ultraviolet components.
• Suppress leakage light (reflection light) into a backside of a panel to sufficiently weak level or shut it out
completely.

Notes on Handling
(1) Static charge prevention
Be sure to take following protective measures. TFT-LCD panels are easily damaged by static charge.
a) Use non-chargeable gloves, or simply use bare hands.
b) Use an earth-band when handling.
c) Do not touch any electrodes of a panel.
d) Wear non-chargeable clothes and conductive shoes.
e) Install conductive mat on the working floor and working table.
f) Keep panels away from any charged materials.
g) Use ionized air to discharge the panels.
(2) Protection from dust and dirt
a) Handle in clean environment.
b) When delivered, a surface of a panel (Polarizer) is covered by a protective sheet.
Peel off the protective sheet carefully not to damage the panel.
c) Do not touch the surface of a panel. The surface is easily scratched. When cleaning, use a clean-room
wiper with isopropyl alcohol. Be careful not to leave stain on the surface.
d) Use ionized air to blow off dust at a panel.
LCX007CN
(3) Other handling precautions
a) Do not twist or bend the flexible PC board especially at the connecting region because the board is
easily deformed.
b) Do not drop a panel.
c) Do not twist or bend a panel or a panel frame.
d) Keep a panel away from heat source.
e) Do not dampen a panel with water or other solvents.
f) Avoid to store or to use a panel in a high temperature or in a high humidity, which may result in
panel damages.
g) Minimum radius of bending curvature for a flexible substrate must be 1mm.
h) Torque required to tighten screws on a panel must be 3kg · cm or less.
