operation make sure to have it sufficiently grounded.
1.11 There are a big number of connection wires distributed around the screen. Please take care not to
touch or scuff them during maintenance or removing the screen, because once they are damaged the
screen will fail to work and it’s not possible to repair it.
1.12 Connector for the circuit board of the screen part is relatively fine and delicate. Please take care in
the replacement operation lest it should get damaged.
1.13 Special care must be taken during transportation and handling because strenuous vibration could
lead to screen glass breakage or damage on the driving circuitry. Be sure to use a strong outer case to
pack it up before transportation or handling.
1.14 Please put it for storage in an environment in which the conditions are under control so as to
prevent the temperature and humidity from exceeding the scope stipulated in the specification. For
prolonged storage please cover it with anti-moisture bag and have them piled and stored in one place.
The environmental conditions are tabulated as below:
Temperature Scope for operation 0~50centigrade
Scope for storage -15~60centigrade
Humidity Scope for operation 20%~80%
Scope for storage 20%~80%
1.15 If a fixed picture is displayed for a long time, difference in its brightness and color may occur
compared with movable pictures. But it doesn’t show any problem and the reason is that there is
reduced density of fluorescent powder in the former. On the other hand, even if changes take place in
the picture, it can keep its brightness for a period of time (several minutes). It’s a feature inherent with
plasma and it’s not abnormal. However please try as much as possible to avoid showing a still picture of
high brightness for a long time during operation.
1.16 As a digitalized display devise, this module is provided with error diffusion technology and the gray
scale and false enhancement of contour can be displayed by reusing of sub-field. As compared with
cathode ray tube, it can be found in the moving picture that at the brim of the face of a person there are
some wrong colors.
1.17 During the display of graph (indicating the gradual change in brightness horizontally or vertically)
resulting from gray scale test it can be found that the brightness for the two adjacent levels is uneven.
This is caused by the reuse of sub-field, the display of load rectification and the electrolysis.
1.18 The screen front plate is of glass. Please make sure that the screen has been put in place during
erection. If it is not in place before the erection begins it may lead to screen crack or breakage.
1.19 Make sure the screw used in the mounting of the screen is of the original specs lest it should cause
damage to the screen due to mismatch. Special care should be taken not to use too long or too big
screw.
1.20 Care must be taken to guard against dust during assembling or dismantling, especially to avoid dirt
from falling in between the screen and the glass lest it should harm the receiving and viewing effect.
1.21 There is piece of insulator stuck on the rear chassis corresponding to the power supply board. It is
used to isolate the cool part from the hot part. Please take care to keep it intact lest it should become a
potential safety trouble.
1.22 In addition to plasma screen, the glass is a part of high value. It has such functions as anti-radiation,
adjustment of color temperature etc. Please handle it carefully.
