6.3.2 Environment
6.3.3 Characteristics
⑨ Do not bend or unbend the lamp cable at the near part of the lamp holding rubber, to avoid the
⑩ Properly connect the plug (backlight side) to adaptable socket (inverter side) without incomplete
⑪ If the lamp cable is attached on the metal part of the product directly, high frequency leak current
⑫ When handling the product, use of an original protection sheet on the product surface (polarizer) is
⑬ Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of
① Do not operate or store in high temperature, high humidity, dewdrop atmosphere or corrosive
② In order to prevent dew condensation occurring by temperature difference, the product packing
③ Do not operate in high magnetic field. Circuit boards may be broken down by it.
④ This product is not designed as radiation hardened.
The following items are neither defects nor failures.
① Characteristics of the LCD (such as response time, luminance, color uniformity and so on) may be
② Display mura, flicker, vertical seam or small spot may be observed depending on display patterns.
③ Optical characteristics (e.g. luminance, display uniformity, etc.) gradually is going to change
④ Do not display the fixed pattern for a long time because it may cause image sticking. Use a screen
⑤ The display color may be changed depending on viewing angle because of the use of condenser
⑥ Optical characteristics may be changed depending on input signal timings.
⑦ The interference noise between input signal frequency for this product's signal processing board
⑧ After the product is stored under condition of low temperature or dark place for a long time, the

connection may occur by hooking the lamp cables. This incomplete connection may cause
abnormal operation of high voltage circuit.

and sunlight, when storing the product.
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)
changed depending on ambient temperature. If the product is stored under condition of low
temperature for a long time, it may cause display mura. In this case, the product should be
operated after enough time being left under condition of operating temperature.

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.
cold cathode fluorescent lamp may not be turned on under the same condition because of the
general characteristic of cold cathode fluorescent lamp. In addition, when Luminance control ratio
is low in pulse width modulation method inverter, the lamp may not be turned on. In this case,
power should be supplied again.
