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 1M(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.

LCX020BK level conversion circuit  
The LCX020BK has a built-in level conversion circuit in the clock input unit on the panel. The input signal level  
increases to HVDD or VVDD. The Vcc of external ICs are applicable to 5 ± 0.5V.

Hckn means Hck1 and Hck2.  
Blk is the timing during SVGA mode (fHckn = 4.0MHz, fVck = 24.0kHz).  
This pulse is positive polarity other than in Macintosh16 mode. Set to L level in Macintosh16 mode.

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.

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.
