1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Disconnect the power plug from AC outlet if the product is not used for a long period of

time.

(5) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display

off.
(6) Do not touch the LCD panel surface with sharp or hard objects.
(7) Do not place heavy objects on the LCD display, video cable, or power cord.
(8) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(9) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas susceptible to excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- Place in direct sunlight.

2. Caution

No modification of any circuit should be attempted. Service work should only be performed after
you are thoroughly familiar
with all of the following safety checks and servicing guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in the
inverter circuit, the voltage is exposed in such areas as the associated transformer circuits.

4. Power Supply Requirements

The external AC power operating range shall be from 90 to 264Vac

5. LCD Module Handling Precautions

5.1. Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or

spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard

surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human

earth when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after once it was

taken out from the container, do not press the center of the CCFL Reflector edge.

Instead, press at the far ends of the CFL Reflector edge softly. Otherwise the TFT

Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor

tilt the Interface Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for

example), do not twist nor bend the TFT Module even momentary. At designing the

enclosure, it should be taken into consideration that no bending/twisting forces are

applied to the TFT Module from outside. Otherwise the TFT Module may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please

follow local ordinances or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module.

1

The LCD module should be supplied by power complied with requirements of Limited

Power Source (IEC60950 or UL1950), or be applied exemption.
(14) The LCD module is designed so that the CFL in it is supplied by Limited Current

Circuit (IEC60950 or UL1950). Do not connect the CFL in Hazardous Voltage Circuit.

5.2. Handling and Placing Methods

Correct Methods: Incorrect Methods:

Only touch the metal frame of the LCD panel
or the front cover of the monitor. Do not touch
the surface of the polarizer.

Take out the monitor with cushions Taking out the monitor by grasping the LCD

Surface of the LCD panel is pressed by fingers

and that may cause “Mura”

Place the monitor on a clean and soft foam pad. Placing the monitor on foreign objects. That

could scratch the surface of the panel or cause

The following tips may help you optimize your display:

• Adjust your computer's graphic card so that it outputs a video signal 1280 x
1024 @ 60 Hz to the LCD dislay. (Look for instructions on “changing the
refresh rate” in your graphic card's user guide.)

• If necessary, make small adjustments using H. POSITION and V. POSITION
until the screen image is completely visible

. (The black border around the
edge of the screen should barely touch the illuminated “active area” of the
LCD dislay.)

Auto Adjust

automatically sizes, centers, and fine tunes the

video signal to eliminate waviness and distortion.
Press the [2] button to obtain a sharper image.

NOTE

: Auto Adjust works with most common video cards. If

this function does not work on your LCD dislay, then lower the
video refresh rate to 60 Hz and set the resolution to its pre-set
value.

Contrast

adjusts the difference between the image background

(black level) and the foreground (white level).

provides several color options: preset color
temperatures and User which allows you to adjust red (R), green
(G), and blue (B). The factory setting for this product is 6500K
(6500 Kelvin).

sRGB

— sRGB is quickly becoming the industry standard for color
management, with support being included in many of the latest
applications. Enabling this setting allows the LCD display to
more accurately display colors the way they were originally
intended. Enabling the sRGB setting will cause the Contrast and
Brightness adjustments to be disabled.

9300K

in most office settings with fluorescent lighting).

6500K

— Adds red to the screen image for warmer white and

richer red. Default setting.

5400K — Adds green to the screen image for a darker color.

A. Scaling controller

GENERAL DESCRIPTION

The TSU16AS is total solution graphics processing IC for LCD monitors with panel
resolutions up to SXGA. It is configured with a high-speed integrated triple-ADC/PLL, a high
quality display processing engine, and an integrated output display interface that can support
LVDS panel interface format. To further reduce system costs, the TSU16AS also integrates
intelligent power management control capability for green-mode requirements and
spread-spectrum support for EMI management.
The TSU16AS incorporates the world’s first coherent oversampled RGB graphics ADC in a
monitor controller system1. The oversampling ADC samples the input RGB signals at a
frequency that is much higher than the signal source pixel rate. This can preserve details in the
video signal that ordinarily would be lost due to input signal jitter or bandwidth limitations in
non-oversampled systems.
The TSU16AS also incorporates a new Dynamic Frame Rate (DFR) generator2 for the digital
output video to the display panel that preserves the advantages of a fixed output clock rate,
while eliminating the output end of frame short-line.

PIN CONFIGURATION & DESCRIPTION

A “CMOS output pin” means it can sink and drive at least 4mA current. It is not recommended
to use such pin as input function.
An “open drain pin” means it can sink at least 4mA current. It can be used as input or output
function and needs an external pull up resistor.
An “8051 standard pin” is a pseudo open drain pin. It can sink at least 4mA current when
output is at low level, and drives at least 4mA current for 160nS when output transits from low
to high, then keeps driving at 120 uA to maintain the pin at high level. It can be used as input
or output function. It needs an external pull up resistor when driving heavy load device.
There is an internal pull-up resistance on each CMOS PAD and an internal pull-down
resistance on each input

Low Power Reset (LVR) & Watchdog Timer

When the voltage level of power supply is below 2.4V (+/-0.4V) for a specific period of time,
the LVR generates a chip reset signal. After the power supply is above 2.4V (+/-0.4V)

INVERTER

In order to drive the CCFLs embedded in the panel module, there is a half bridge inverter to
convert by the controller.
The input 12V up to hundreds of AC voltage output.
The inverter is formed by symmetric in order to drive the separate lamp modules.
The input stage consists of a PWM controller, half bridge inverter, and switching MOSFET to
convert DC input into AC output.
The output stage consists of a tuning capacitor, coupling capacitor, transformer, push-pull
MOSFET pair to boost AC output up to hundreds of voltage.
And one resister is serial to lamp for output voltage feedback.
There are two signal to control the inverter which come from system.
Logic “high” level which send to I901 is turn on the inverter.
BRI signal control brightness by DC level which was integral from PWM signal.
