Do not push nor pull the interface connectors while the product is working.
Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the
damage for high voltage side of the lamp.
When handling the product, use of an original protection sheet on the product surface (polarizer) is
recommended for protection of product surface. Adhesive type protection sheet may change color or
characteristics of the polarizer.
6.3.2 Environment
Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive gases.
Keep the product in packing box with antistatic pouch in room temperature to avoid dusts and
sunlight, when storing the product.
In order to prevent dew condensation occurring by temperature difference, the product packing box
should be opened after enough time being left under the environment of an unpacking room.
Evaluate the leaving time sufficiently because a situation of dew condensation occurring is changed
by the environmental temperature and humidity. (Recommended leaving time: 6 hours or more with
packing state)
Do not operate in high magnetic field. Circuit boards may be broken down by it.
This product is not designed as radiation hardened.
6.3.3 Characteristics
The following items are neither defects nor failures.
Response time, luminance and color may be changed by ambient temperature.
Display mura, flicker, vertical seam or small spot may be observed depending on display patterns.
Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change
depending on operating time, and especially low temperature, because the LCD has cold cathode
fluorescent lamps.
Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
saver, if the fixed pattern is displayed on the screen.
The display color may be changed depending on viewing angle because of the use of condenser sheet
in the backlight.
Optical characteristics may be changed depending on input signal timings.
The interference noise between input signal frequency for this product's signal processing board and
luminance control frequency of the inverter may appear on a display. Set up luminance control
frequency of the inverter so that the interference noise does not appear.
6.3.4 Other
All VDD and GND terminals should be used without any non-connected lines.
Do not disassemble a product or adjust variable resistors.
See "REPLACEMENT MANUAL FOR BACKLIGHT UNIT", when replacing backlight lamps.
Pack the product with original shipping package, in order to avoid any damages during
transportation, when returning the product to NEC for repair and so on.
The LCD module by itself or integrated into end product should be packed and transported with
display in the vertical position. Otherwise the display characteristics may be degraded.
