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 high quality and safety approved AC/DC power cord. (5) Disconnect the power plug from AC outlet if the product is not 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 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. 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 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. 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.

Correct 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.
Incorrect Methods:

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.)

4. Circuit Description
1. WORKING THEOREM
A. DC-DC CONVERTER
This brick converts the 5V input voltage to 3.3V and 1.8V for controller use. It consists of a Liner Regulator IC (AIC117), filter capacitor, and constant voltage capacitor. The AIC1117 is a low dropout three terminal regulator with 800mA output current capability. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Internal current and thermal limiting provides protection against any overload condition that would create excessive junction temperatures.
B. A/D converter
The gmZAN3SL provides all the key display functions required for displaying a good quality image on a LCD
panel when connected to the PC source with analog interface. The integrated functions include a high-speed triple-ADC and PLL, a high quality zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and LVDS Transmitters. Its provides a front-end analog interface with standard VGA compliance and an output industry standard LVDS interface for speed grade up to XGA and SXGA respectively. Typical gmZAN3SL based design need an external 8051 equivalent MCU with integrated flash. It provides the flexibility of choosing either 8bit parallel or 6wire host interface. Integrated LVDS transmitters and PWM based backlight control circuitry provides direct interconnect to LCD panels and backlight inverters. Integrated Schmitt circuit, integrated reset circuit and single crystal base makes gmZAN3XL/SL an ideal choice for the entry- level SXGA monitor design.
D. MCU:
The MTV312M micro-controller is an 8051 CPU core embedded device especially tailored for CRT/LCD Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in PWM DACs, VESA DDC interface, 4- channel A/D converter, and a 64K-byte internal program Flash-ROM.

- Normally when the primary mode 1280*1024@60Hz is well adjusted and compliant with the specification, the secondary display modes will be great possible to be compliant with the spec. But we still have to check with the general test pattern to make sure every secondary is compliant with the specification.
5-4.11 All Modes Reset
After final QC step, we have to erase all saved changes again and restore the factory defaults. You should do “All Mode Reset” again.
