[Note 6] Definition of white uniformity ;
10. Handling Precautions of the module
a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) This product is using the parts (inverter, CCFT etc), which generate the high voltage.
c) Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.4. Voltage difference generated
d) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or
e) Since the front polarizer is easily damaged, pay attention not to scratch it.
f) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
g) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
h) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
i) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into
j) Please consider to minimize the influence of EMI and the exogenous noise before designing the grounding of
White uniformity is defined as the following with five measurements. (A∼E)
Therefore, during operating, please don't touch these parts.
