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.

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 @ 60Hz to the LCD display. (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 display.)

Control Explanation

Input Priority

If multiple computers will be connected to the display, this function can be used to select which computer has priority Depending on the selected Input Priority, the display will do a one time detection for available inputs when first powered on.

For example: If the Input Priority setting is D-SUB=>D-SUB2=>DVI, then the first priority will be given to D-SUB1 when the display turns on. If there is no video signal on D-SUB1, then the next priority will be given to D-SUB-2, etc… In the case of only one signal being present at the three inputs, then the display will automatically detect and display that signal.

The Input Priority setting can also be disabled. In this case, the input will return to the last setting when the display is first turned on. The user will need to control all the port settings manually under this condition. Inputs can be switched quickly by pressing the "Up" arrow button on the front panel controls.

OSD Position

allows you to move the on-screen display menus

and control screens.

OSD Timeout

sets the length of time the on-screen display screen is displayed. For example, with a “30 second” setting, if a control is not pushed within 30 seconds, the display screen disappears.

OSD Background

On/Off

allows you to turn the On-Screen Display

background On or Off.

OSD Pivot

This function is used to rotate the OSD menu,

when the display is changed from Landscape to Portrait mode.

Memory Recall

returns the adjustments back to factory settings if the display is operating in a factory Preset Timing Mode listed in the Specifications of this manual.

4. Circuit Description

Circuit Description

1. Power supply (DC/DC Converter)

The AP1501 is monolithic IC designed for M/B DC/DC converter, and owns the ability of driving a 3A load without any additional transistor component. The AP1501 operates at a switching frequency of 150KHz and thus allows smaller-sized filter components than what would be needed with lower frequency switch regulator.

2. Flash Memory

The Pm39LV020R is a 2 Megabit, 3.3 Volt-only Flash Memory organized as 262,144 bytes of 8 bits each. This device is designed to use a 3.0 Volt to 3.6 Volt power supply to perform in-system programming. The 2 Megabit memory array is divided into uniform 4Kbyte sector or uniform 64Kbyte blocks for data and/or code storage. The block architecture allows users to flexibly make chip erase or block erase operation. The block erase feature allows a particular block to be erased and reprogrammed without affecting the data in other blocks. After the device performs chip erase or block erase operation, it can be reprogrammed on a byte-by-byte basis.

3. GM5321

The gm5321 is a graphic processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA resolution. It provides all key IC functions required for the highest quality LCD monitors. On-chip functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI

receiver, a high quality zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and an on-chip microcontroller (OCM). With this level of integration, the gm5321 devices simplify and reduce the cost of LCD monitors while maintaining a high-degree of flexibility and quality.

gm5321 System Design Example

4. LVDS (THC63LVDM83A)

The THC63LVDM83A transmitter converts 28 bits of CMOS/TTL data into LVDS (Low Voltage Differential Signaling) data stream. A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. The HC63LVDM83A can be programmed for rising edge or falling edge clocks through a dedicated pin. The THC63LVDF84A receiver converts the LVDS data streams back into 28 bits of CMOS/TTL data with falling edge clock. At a transmit clock frequency of 85MHz, 24 bits of RGB data and 4 bits of LCD timing and control data (HSYNC, VSYNC, CNTL1, CNTL2) are transmitted at a rate of 595 Mbps per LVDS data channel.
