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

ViewSonic Corporation Confidential - Do Not Copy

VG2030m-1

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

4. Circuit Description

The TSUM57AK 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, an integrated DVI receiver, a high quality display processing engine,

and an

SDS panel interface format. To further reduce system costs, the TSUM57AK also integrates intelligent power management

control capability for green-mode requirements and spread- spectrum support for EMI management.

The TSUM57AK incorporates the world’s first coherent oversampled RGB graphics ADC in a monitor controller system. 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 TSUM57AK also incorporates a new Dynamic Frame Rate (DFR) generator

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.
