• Horizontal resolution: 400 TV lines
• High optical transmittance: 4.0% (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
• Up/down and/or right/left inverse display function
• 4:3 and 16:9 aspect switching function
• Power save mode (Through current reduction by stop of level shifter and scanner during power supply cutoff)
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.

Level Conversion Circuit
The LCX033ANB 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.
(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, RGT,
VCK, BLK, DWN and STB in the case of a singlephase input)

and is maximized when the pin is grounded. (Refer

Flicker (F) is given by the formula (7). DC and AC (NTSC: 30Hz, rms, PAL: 25Hz, rms) components of the

System II.

8. Image Retention Time
Apply the monoscope signal to the LCD panel for 60 minutes and then change this signal to the gray scale

the time till the residual image becomes indistinct.

9. Method of Measuring the Optimum Vcom
There are two methods of measuring the optimum Vcom using the photoelectric element.
9-1. Method of Measuring Flicker
In the field invert drive mode, adjust the flicker level of the half tone (Vsig = 1.5 to 2.5V) using the
photoelectric element and oscilloscope so that its 30Hz component becomes minimum. The Vcom value
at this time is taken to be the optimum Vcom.
9-2. Method of Measuring Contrast
In the normal 1H invert drive mode, adjust the optical output voltage of the half tone (Vsig = 1.5 to 2.5V) so
that it becomes minimum. The Vcom value at this time is taken to be the optimum Vcom.

2. LCD Panel Operations
• A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse
to every 225 gate lines sequentially in every horizontal scanning period. A vertical shift register scans the
gate lines from the top to bottom of the panel at DWN = High level.
• The selected pulse is delivered when the enable pin turns to High level. PAL mode images are displayed by
controlling the enable and VCK pin. The enable pin should be High when not in use.
• A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits
applies selected pulses to every 800 signal electrodes sequentially in a single horizontal scanning period.
• Through current of the level shifter during power supply cutoff can be reduced by STB pin. (power save
mode)
Power save mode is set at STB = Low level.
• Vertical and horizontal drivers 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 225 × 800 dots to display a picture in
a single vertical scanning period.
• Pixel dots are arranged in a delta pattern, where sets of RGB pixels are positioned with 1.5-dot shifted
against adjacent horizontal line. 1.5-dot shift of a horizontal driver output pulse against horizontal
synchronized signal is required to apply a video signal to each dot properly. 1H reversed displaying mode is
required to apply video signal to the panel.
• The video signal shall be input with polarity-inverted system in every horizontal cycle.
• Timing diagrams of the vertical and the horizontal right-direction scanning (RGT = High level) display cycle
are shown below:

• This LCD panel provides the following functions.
• Right/left inverse mode
• Up/down inverse mode
These modes are controlled by two signals, RGT and DWN.

HCK1 and HCK2 should be inverted to display the left-direction horizontal scanning (RGT = Low level).
This inversion enables the center of the image to be fixed by eliminating offsets. (When an example of
system mentioned on this data sheet is used, TG performs this operation automatically.)

Horizontal display cycle (48.4µs)
The horizontal display cycle consists of 800/3 = 267 clock pulses because of RGB simultaneous sampling.

3. RGB Simultaneous Sampling
Horizontal driver samples R, G and B signal simultaneously, which requires the phase matching between R,
G and B 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.
Two methods are applied for the delaying procedure: Sample and hold and Delay circuit. These two block
diagrams are as follows.
The LCX033ANB 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 B and G signals.

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) Operate 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.
(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.
