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) Use only a high quality, safety approved AC/DC power cord.
(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas containing excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- 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. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when connecting or disconnecting input connector.
(3) Wipe off water drops 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 ensure human earth when handling.
(7) Do not open or modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module in any direction.
(9) In the event that a Module must be put back into the packing container slot after it was taken out of 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 or 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 or

bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration
that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local

ordinances or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module

should be supplied with power that complies with the requirements of Limited Power Source
(IEC60950 or UL1950), or an exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950

or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit.

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.
