Luminance for panel without microlens

3. V-T characteristics

V-T characteristics, the relationship between signal
amplitude and the transmittance of the panels, are
measured by System II. V90, V50 and V10 correspond
to the each voltage which defines 90%, 50% and 10%
of transmittance respectively.
The angles of incidence for R, G and B are as shown
in the diagram below.

LCX019AM

2. LCD panel operations

[Description of basic operations]

The basic operations of the LCD panel are shown below based on the wide-display mode.

• A vertical driver, which consists of vertical shift registers, enable-gates and buffers, applies a selected pulse
to every 480 gate lines sequentially in every horizontal scanning period.

• A horizontal driver, which consists of horizontal shift registers, gates and CMOS sample-and-hold circuits,
applies selected pulses to every 1199.5 signal electrodes sequentially in a single horizontal scanning period.

• 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 480 × 1199.5 dots to display
a picture in a single vertical scanning period.

• The LCD pixel dots are arranged in a delta pattern, where the dots connected to the identical signal line is
positioned with 1.5-dot offset against an adjacent horizontal line. Horizontal Start Pulse (HST) is generated
with 1.5-bit offset between the horizontal lines to regulate the above offset. HCK and sample-and-hold (S/H)
pulses follow the same 1.5-bit offset scheme.

• The video signal shall be input with polarity-inverted system in every horizontal cycle.

• Timing diagrams of the vertical and the horizontal display cycle are shown below:

• The analog signal (PSIG) shall be input by 1H inversion synchronized with the video signal.

3. 6-dot simultaneous sampling

Horizontal driver samples SIG1 to SIG6 signals simultaneously, which requires the phase matching between
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.
The block diagram of the delaying procedure using simple-and-hold method is as follows.
The LCX019AM 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 in the order of the SIG6, SIG4, SIG5, SIG3, SIG1 and SIG2 signals.

Optical Characteristics

1. Microlens outline

The LCX019AM 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 7.75 ± 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 7.75 ± 0.5°.

Center

Right

Left

Pad

Optimum angle of
incidence 7.75 ± 0.5°

Optimum angle of
incidence 7.75 ± 0.5°

(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 I.)

3. Recommended projection optical system

The maximum egress light angle for light passing through the LCD is approximately ±20°. Therefore, setting
the F stop of the projection lens to about 1.5 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.

LCX019AM

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 LCX019AM and the light source as necessary depending on the light source.
The lighting intensity should be 1 million lux 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 LCX019AM.

1) Light reflected from the optical system to the panel should be 20,000 lux or less.

2) Particular care should be taken for the panel incident angle distribution when designing optical systems
for use with the LCX019AM.

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 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 (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 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).
