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 adapter.
(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. Power Supply Requirements
The external power converter for this display utilizes AC and DC cords, AC cord is detachable, but DC cord is permanently
attached. Any attempt to replace another adapter could result in serious problem on the display.
5. LCD Module Handling Precautions
5.1 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.

4. Circuit Description
1. Power s»(DC/DC Converter)
The AP1501 is monolithic IC designed for M/B DC/DC converter, with the ability of driving a 3A load without any
additional transistor component.
The AP1501 operates at a switching frequency of 150 kHz and thus allows smaller-sized filter components than
would be needed with lower frequency switch regulator.
2. Flash Memory
The Pm39LV010R is a 1 Megabit, 3.3 Volt-only Flash Memory organized as 131,072 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 1 Megabit memory array is divided into thirty-two uniform blocks of 4 Kbytes each 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.

gm5110/5120 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.

Step 2. Save these three files<bdisp.txt>, <p204_205.bin> and <710LG_V2_48.bin> in a hard disk (better in a root directory, e.g.
C:\ or D:\ ).
Step 3. Open <bdisp.txt> file. Key in the path where you save the driver <p204_205.bin> and firmware <710LG_V2_48.bin>.
Step 6. Before executing the firmware program, please test the connection between the monitor and fixtures. Key in “test” after
“Gprobe,” and then press “Enter.”
If the test result shows “passed,” it means the connection is well. If not (failed), it means the connection has
problems. Then you need to check the setup procedure or reboot the PC, or simply use another PC to do the
firmware upgrade.
