6. Installation of Display Panel
Precautions
In practical applications, generally several LCD display panels are combined into
an M×N array, which will become a LCD display wall with ultrahigh resolution.
Various factors should be taken into consideration during the installation. So
before the installation, the preparatory survey, scheme design work and others
should be performed. All installation operation should be done by qualified
engineers of VTRON or its agents. For more information about installation of
LCD display panels on site, please consult VTRON engineers.
The M×N LCD display wall system is composed of front display panels, mounting
racks and other devices.
Note: For installation details, please refer to the installation instructions.
User Manual VTRON LCD Display Panel

7. Use of Display Panel
Use Instructions
If the display panel gives out any unusual noise, smoke or smell, plug off the
power connector immediately, and turn to the qualified technician for help.
Plug off the power connector in case of thunder storm or when the display panel
will be idle for a long time.
Check the power cable regularly to see if its insulation is intact and the contact
gets overheated.
In the following situations, please plug off the power connector and turn to the
qualified technicians:
The power connector or power cable is damaged or worn out;
Liquid drops into the display panel;
The display panel falls down to the floor or the enclosure is damaged;
The display panel has obvious functional exception or performance change;
The LCD is a fragile product made of glass. Any falling, striking or strong
vibration will cause the breakage of the glass. It is prohibited to forcefully press
the display zone of the LCD, or squeeze the LCD screen and frame during the
installation. You should pay attention to the overall evenness of the LCD and
avoid any bending or distortion caused by external force. Do not scratch the
display zone with hard objects.
The LCD may become crystallized when operating or stored in the temperature
and humidity range below the specifications, and this damage is unrecoverable. If
it is operated or stored in the temperature and humidity range above the
specifications, the crystal may turn into the isotropous liquid, and this damage is
also unrecoverable. Please store and use this display panel within the allowable
temperature and humidity range.
User Manual VTRON LCD Display Panel
- 25 -
Avoid exposing the LCD module to direct sunshine or UV radiation.
The operating environment shall meet the following conditions: At least 100mm
clearance shall be maintained above, below and in front of the combined LCD
display wall. It is recommended that a clearance of more than 200mm shall be
reserved, so that the air around the display wall can be circulated effectively. The
display wall shall be kept away from the heat source.
User Manual VTRON LCD Display Panel

7.1 System Startup/Shutdown
Startup sequence:
1. Check if the main power supply for the whole display wall system is ON.
2. Check if the power switch on the LCD display panel back plate is ON.
3. Start the control PC and run the control software (if the system requires the use
of the control software).
4. Start all the display panels via the control software or by pressing the system
switch on the interface board.
Shutdown:
Shut down all the display panels via the control software interface or by pressing
the system switch on the interface board.
Note:
When you select to shut down the display panel in the control software interface,
this operation only switches the display panel to standby state, and the power
supply of the display panel has not been shut down. You need to use the power
switch on the rear panel to completely shut down the power supply of the display
panel. When the display panels are in standby state, you can start all the display
panels again in the control software interface.
User Manual VTRON LCD Display Panel

7.2 Display Signal Source
You can operate and manage all the input signal source contents through
professional control software, and display these signal source contents on the LCD
display panel.
For more information about control software configured onsite and its operation
instructions, please consult the system/equipment administrator.
8. Daily Maintenance
Precautions for maintenance
There is high voltage inside the equipment. The chassis shall be opened by the
specialized technician only.
This product is a precise device, and you are not allowed to open, disassemble or
modify on your own. Otherwise, the LCD or other internal components may be
damaged, making the equipment unusable.
The LCD surface shall be kept clean during the use and storage. If any water drip
is retained on the LCD, it will result in discolor or stain of the LCD. When there is
any stain on the LCD, wipe it off with cotton or soft cloth. It is prohibited to use
gasoline, alcohol or other chemicals to clean the screen.
If the screen is damaged and the liquid crystal drops onto your hands or clothes,
wash it with soap and clean water.
Do not press the screen surface of the LCD display panel forcefully.
