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.

3.5 Other User/Service Information

a. SIGNAL OVER RANGE:

If the horizontal or vertical or both input signal frequency exceed the acceptable input frequency
range, the monitor keeps indicating the “SIGNAL OVER RANGE” as the OSD information after
2 seconds. If both input signal frequencies are in the acceptable frequency range, the monitor
puts out the OSD indication and goes back to normal state.

b. RGB NO INPUTSIGNAL:

In case of the pin 14 is +5V, the monitor recognizes PC is connected. Otherwise, the pin 14 is
low (approx. 0V), horizontal or vertical input signals are not exist, the monitor displays OSD
information〝RGB NO INPUTSIGNAL〞5 seconds, then goes to power save.

4. Circuit Description

A. A/D converters

The ADC is a 7-bit 4-channel analog-to digital converter ,the structure of these ADCS is 7-bit
successive approximation ,analog voltage is supplied from external sources to the A/D input pins and
the result of the conversion is stored In the 7-bit data latch registers(ADC0_REG~ADC3_REG).The
A/D cannels are activated by cleaning the correspondent control bits in the ADC_CON control register,
when users write”1” into one of the enable control bits(EN_ADC0~EN-ADC3),its correspondent I/O pin
will be switched to the A/D Converter input pin

The conversion will be started by setting STRT_ADC Bit, user can monitor this bit to get the valid A/D
channel, its latched data is meaningful, the analog voltage to be measured should be stable during the
conversion operation and the variation will not exceed 1 LSB for the best accuracy in measurement
