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 which supports Macintosh16∗1/SVGA/VGA/PC98
∗2
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.

Contrast Ratio (CR) is given by the following formula (1).
CR = ... (1)
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.

2. Optical Transmittance
Optical Transmittance (T) is given by the following formula (2).
T = × 100 [%] ... (2)
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.
4. V-T Characteristics
V-T characteristics, or the relationship between signal amplitude and the transmittance of the panel, are measured by System II by inputting the same signal 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.
V50RG = V50R – V50G ... (3) V50BG = V50B – V50G ... (4)

Response time ton and toff are defined by formulas (5) and (6) respectively.
ton = t1 – tON ... (5) toff = t2 – tOFF ... (6)
t1: time which gives 10% transmittance
of the panel.
t2: time which gives 90% transmittance

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.
F [dB] = 20log { } ... (7)
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.

Monoscope signal conditions Vsig = 7.0 ± 4.5 or 7.0 ±2.0 [V] (shown in the right figure) Vcom = 6.6V
∗
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

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.

VGA/NTSC: 640 × 480
PC98: 640 × 400 WIDE: 832 × 480
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 left­direction 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.
