LCX020BK
1.8cm (0.7-inch) Color LCD Panel
Description
The LCX020BK is a 1.8cm 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.
RGB dots are arranged in a striped pattern optimum
for data applications and capable of displaying fine
text and vertical lines.
The adoption of an advanced on-chip black matrix
realizes a high luminance screen, and high picture
quality is possible with built-in cross talk free and
ghost free circuits.
This panel has a polysilicon TFT high-speed
scanner and built-in function to display images
up/down and/or right/left inverse. In addition, the
built-in 5V interface circuit leads to lower voltage of
timing and control signals.
The panel contains a display area varying circuit
1
2
which supports Macintosh16 /SVGA/VGA/PC98
data signals by changing the display area according
to the type of input signal. In addition, double-speed
processed NTSC/PAL/WIDE can also be supported.

Input Equivalent Circuits
To prevent static charges, protective diodes are provided for each pin except the power supplies. In addition,
protective resistors are added to all pins except video signal inputs. All pins are connected to Vss with a high
resistance of 1MΩ (typ.). The equivalent circuit of each input pin is shown below: (Resistor value: typ.)

The optimum typical value of the common pad voltage may lower its suitable voltage according to the set
construction to use. In this case, use the voltage of which has maximum contrast as typical value. When the
typical value is lowered, the maximum and minimum values may lower.
Input a uniformity improvement signals PSIGR, PSIGG and PSIGB in the same polarity with video signals
SIGR1 to 6, SIGG1 to 6 and SIGB1 to 6 and which is symmetrical to VVC. PSIGR, PSIGG and PSIGB have
two steps as shown by the waveform in the figure below, and in the table above, the upper value indicates
the signal level of the first step, and the lower value, the signal level of the second step.
Here, the rising and falling of PSIGR, PSIGG and PSIGB are synchronized with the rising of PCG pulse,
and the rise and fall times trPSIGR, trPSIGG, trPSIGB, tfPSIGR, tfPSIGG and tfPSIGB are suppressed
within 800ns.

HVDD = 15.5V, VVDD = 15.5V
VVC = 7.0V, Vcom = 6.6V
(2) Measurement temperature
25°C unless otherwise specified.
(3) Measurement point
One point in the center of the screen unless otherwise specified.
(4) Measurement systems
Two types of measurement system are used as shown below.
(5) Video input signal voltage (Vsig)

L (White) is the same expression as defined in the "Contrast Ratio" section.
Optical transmittance is measured by System I.
3. Chromaticity
Chromaticity of the panel is measured by System I. Raster modes of each color are defined by the
representations at the input signal amplitude conditions shown in the table below. System I uses x and y of
the CIE standards as the chromaticity here.

amplitude VAC to each input pin. V90, V50, and V10
correspond to each voltage which defines 90%, 50%,
and 10% of transmittance respectively.

5. Half Tone Color Reproduction Range
The half tone color reproduction range of the LCD
panel is characterized by the differences between the
V-T characteristics of R, G and B. The differences of
these V-T characteristics are measured by System II.
System II defines signal voltages of each R, G and B
raster mode which correspond to 50% of transmittance,
V50R, V50G and V50B respectively. V50RG and V50BG
represent the differences between V50R and V50G and
between V50B and V50G, and are given by the following
formulas (3) and (4) respectively.

7. Flicker
Flicker (F) is given by the formula (7). DC and AC (MAC16/SVGA/VGA/PC98/NTSC: 30Hz, rms, PAL:
25Hz, rms) components of the panel output signal for gray raster mode are measured by a DC voltmeter
and a spectrum analyzer in System II.

R, G, B input signal voltage for gray raster mode is given by
Vsig = 7.0 ± V50 [V]
where: V50 is the signal amplitude which gives 50% of
transmittance in V-T curve.
8. Image Retention Time
Image retention time is given by the following procedures.
Apply a monoscope signal to the LCD panel for 60 minutes and then change this signal to the gray scale of
Vsig = 7.0 ± VAC [V] (VAC: 3 to 4V) so as to give the maximum image retention. Hold input signal VAC. The
time for the residual image to disappear gives the image retention time.

2. LCD Panel Operations
[Description of basic operations]
• A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse
to every 624 gate lines sequentially in every single horizontal scanning period. (in Macintosh16 mode)
• A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits,
applies selected pulses to every 2496 signal electrodes sequentially in a single horizontal scanning period.
These pulses are used to supply the sampled video signal to the row signal lines.
• Vertical and horizontal shift registers address one pixel, and then Thin Film Transistors (TFTs; two TFTs for
one dot) turn on to apply a video signal to the dot. The same procedures lead to the entire 2496 × 832 dots to
display a picture in a single vertical scanning period.
• The data and video signals shall be input with polarity-inverted system in every horizontal cycle.
[Description of operating mode]
The LCD panel can change the angle of view by displaying a black frame to support various signal systems.
The angle of view is switched by MODE1, 2 and 3. However, the picture center does not change. The angle of
view mode settings are shown below.

The LCD panel has the following functions to easily apply to various uses, as well as various signal systems.
• Right/left inverse mode
• Up/down inverse mode
These modes are controlled by two signals (RGT and DWN). The right/left and up/down mode settings are
shown in the tables below.

Right/left and up/down mean the direction when the Pin 1 marking is located at the right side with the pin block
facing upward.
Since the display area is located in the center of the panel in each mode, the start pulse, clock phase and
polarity for both the H and V systems must be varied. The phase relationship between the start pulse and the
clock for each mode is shown on the following pages.

3. 18-dot Simultaneous Sampling
The horizontal shift register performs SIGR1 to SIGR6, SIGG1 to SIGG6 and SIGB1 to SIGB6 signal sampling
simultaneously, which requires phase matching between each signal to prevent the horizontal resolution from
deteriorating. Phase matching by an external signal delaying circuit is needed before applying video signals to
the LCD panel.
The block diagram of the delaying procedure using the sample-and-hold method is as follows. The following
phase relationship diagram indicates the phase setting for right-direction scanning (RGT = High level). For left-
direction scanning (RGT = Low level), the phase settings should be inverted for the SIGR1 to SIGR6, SIGG1 to
SIGG6 and SIGB1 to SIGB6 signals.

Notes on Handling
(1) Static charge prevention
Be sure to take the following protective measures. TFT-LCD panels are easily damaged by static charges.
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 mats 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 dust
a) Operate in a clean environment.
b) When delivered, panel surface (Polarizer) is covered by a protective sheet. Peel off the protective sheet
carefully so as not to damage the panel.
c) Do not touch the polarizer surface. The surface is easily scratched. When cleaning, use a clean-room
wiper with isopropyl alcohol. Be careful not to leave a stain on the surface.
d) Use ionized air to blow dust off the polarizer.
(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 the panel.
c) Do not twist or bend the panel or panel frame.
d) Keep the panel away from heat sources.
e) Do not dampen the panel with water or other solvents.
f) Avoid storing or using the panel at a high temperature or high humidity, which may result in panel
damages.
