4.1cm (1.6-inch) LCD Panel (with microlens)  
For the availability of this product, please contact the sales office.  
Description  
The LCX021AM is a 4.1cm diagonal active matrix  
TFT-LCD panel addressed by polycrystalline silicon  
super thin film transistors with built-in peripheral driving  
circuit. This panel allows full-color representation  
without color filters through the use of a microlens.  
The striped arrangement suitable for data projectors  
is capable of displaying fine text and vertical lines.  
The adoption of an advanced on-chip black matrix  
realizes high picture quality by incorporating a high  
luminance screen, 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. The built-in 5V  
interface circuit leads to lower voltage of timing and  
control signals.  
The panel contains an active area variable circuit  
1
which supports SVGA 4:3/PC98 8:5 data signals  
by changing the active area according to the type of  
input signal.  
1 "PC98" is a trademark of NEC Corporation.  
Features  
The number of active dots: 1,456,000 (1.6-inch; 4.1cm in diagonal)  
Supports SVGA (804 × 3 × 604) and PC98 1 (804 × 3 × 500)  
Effective aperture ratio: 70% (reference value)  
Built-in cross talk free and ghost free circuits  
High contrast ratio with normally white mode: 150 (typ.)  
Built-in H and V drivers (built-in input level conversion circuit, 5V driving possible)  
Up/down and/or right/left inverse display function  
Element Structure  
Dots: 804 × 3 (H) × 604 (V) = 1,456,848

The 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 PSIGB, PSIGG and PSIGR in the same polarity with video signals  
SIGB1 to 6, SIGG1 to 6 and SIGR1 to 6 and which is symmetrical to VVC. Also, the rising and falling of  
PSIGB, PSIGG and PSIGR are synchronized with the rising of PCG pulse, and the rise time trPSIG and fall  
time tfPSIG are suppressed within 800ns (as shown in a diagram below).

Reflection Preventive Processing  
When a phase substrate which rotates the polarization axis is used to adjust to the polarization direction of a  
polarization screen or prism, use a phase substrate with reflection preventive processing on the surface. This  
prevents characteristic deterioration caused by luminous reflection.

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 604 gate lines sequentially in a single horizontal scanning period (in SVGA mode).  
A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits,  
applies selected pulses to every 804 × 3 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 turn on Thin Film Transistors (TFTs; two  
TFTs) to apply a video signal to the dot. The same procedures lead to the entire 604 × 804 × 3 dots to  
display a picture in a single vertical scanning period.  
The data and video signals shall be input with the 1H-inverted system.  
[Description of operating mode]  
This LCD panel can change the active area by displaying a black frame to support various computer or video  
signals. The active area is switched by MODE. However, the center of the screen is not changed. The active  
area setting modes are shown below.

3. 18-dot simultaneous sampling  
The horizontal shift register samples SIGB1 to SIGB6, SUGG1 to SIGG6 and SIGR1 to SIGR6 signals  
simultaneously. This requires phase matching between signals SIGB1 to SIGB6, SIGG1 to SIGG6 and SIGR1  
to SIGR6 to prevent the horizontal resolution from deteriorating. Thus phase matching between each signal is  
required using an external signal delaying circuit before applying the video signal to the LCD panel.  
The block diagram of the delaying procedure using simple-and-hold method is as follows. The following phase  
relationship diagram indicates the phase setting for right scan (RGT = High level). For left scan (RGT = Low  
level), the phase settings for signals SIGB1 to SIGB6, SIGG1 to SIGG6 and SIGR1 to SIGR6 are exactly  
reversed.

Optical Characteristics  
1. Microlens outline  
The LCX021AM has a single built-in microlens on the substrate side facing the TFT for the three TFT panel  
picture elements. This microlens serves the following purposes.  
(1) The microlens converges the incident light striking the LCD panel to the dot aperture in order to improve  
the effective aperture ratio and increase the display brightness.  
(2) The microlens provides a color representation by distributing the light flux for each of the three primary  
colors R, G and B which strike the panel at different angles to the dot apertures corresponding to each  
color.  
This allows the light utilization efficiency to be improved by eliminating the light absorption by the color filter,  
which had been unavoidable with conventional single panel projectors.  
2. Recommended lighting conditions  
In order to bring out the full light converging effects of the microlens and provide a color representation with  
high color purity, the following lighting is recommended.  
(1) The incident light angle of the three primary colors should be as shown in the figure below. The center  
light should strike the panel from the panel normal direction, and the left and right light from angles  
inclined to the right and left of the panel normal direction. The design optimal angle of incidence is the  
range of 6.0 ± 0.5°. However, the optimal angle of incidence may be altered slightly depending on the  
panel. Be sure to allow adjustment of the mutual angles of the dichroic mirrors so that the angle of  
incidence can be varied within the range of 6.0 ± 0.5°.  
Left  
Center  
Right  
Optimum angle of incidence  
6.0 ± 0.5°  
Optimum angle of incidence  
6.0 ± 0.5°  
Pad  
(2) Effective light: The normal direction (center light), left light and right light noted above should strike the  
panel at an angle of ±3.5° or less. Light with a dispersion angle greater than this value will  
strike adjoining dot apertures and cause the color purity to worsen. (See the incident angle  
distribution for System Ι.)  
3. Recommended projection optical system  
The maximum egress light angle for light passing through the LCD is approximately ±17°. Therefore, setting  
the F stop of the projection lens to about 1.7 is recommended in order to maximize the light converging effects  
of the microlens and provide a representation with excellent color balance. If the projection lens F stop is larger  
than this value, the right and left light are kicked accordingly by the projection lens, thereby reducing the  
egress light flux to the screen and the same time shifting the white balance.

LCX021AM  
Notes on Operation  
(1) Lighting spectrum and intensity  
Use only visible light with a wavelength λ = 415 to 780nm as a light source. Light with a wavelength λ >  
780nm (infrared light) will produce unwanted temperature rises. Light with a wavelength λ < 415nm  
(ultraviolet light) will produce irreversible changes in the display characteristics. To prevent this, be sure to  
mount UV/IR cut filters between the LCX021AM and the light source as necessary depending on the light  
source.  
The lighting intensity should be 1 million lx or less, and the panel surface temperature should not exceed  
55°C.  
(2) Lighting optical system  
Care should be taken for the following points concerning the optical system mounted on the LCX021AM.  
1) Light reflected from the optical system to the panel should be 20,000 lx or less.  
2) Particular care should be taken for the panel incident angle distribution when designing optical systems  
for use with the LCX021AM.  
3) The panel surface temperature distribution should not exceed 10°C.  
4) Light should shine only on the effective display area within the LCD panel and not on other unnecessary  
locations. Leakage light may produce unwanted temperature rises.

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 dirt  
a) Operate in a clean environment.  
b) When delivered, a surface of a panel (glass panel) is covered by a protective sheet.  
Peel off the protective sheet carefully not to damage the glass panel.  
c) Do not touch the surface of the glass panel. 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 off dust at the glass 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 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.  
i) Use appropriate filter to protect a panel.  
j) Do not pressure the portion other than mounting hole (cover).
