⑧ Do not push nor pull the interface connectors while the product is working.
⑨ 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.
⑩ Properly connect the plug (backlight side) to adaptable socket (inverter side) without incomplete
connection. After connecting, be careful not to hook the lamp cables because incomplete
connection may occur by hooking the lamp cables. This incomplete connection may cause
abnormal operation of high voltage circuit.
⑪ If the lamp cable is attached on the metal part of the product directly, high frequency leak current
to the metal part may occur, then the brightness may decrease or the lamp may not be turned on.
⑫ 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.
⑬ Usually liquid crystals don't leak through the breakage of glasses because of the surface tension of
thin layer and the construction of LCD panel. But, if you contact with liquid crystal for the worst,
please wash it out with soap.
6.3.2 Environment
① 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.
② 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)
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.
6.3.3 Characteristics
The following items are neither defects nor failures.
① Response time, luminance and color may be changed by ambient temperature.
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
depending on operating time, and especially low temperature, because the LCD has cold cathode
fluorescent lamps.
④ 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.
⑤ The display color may be changed depending on viewing angle because of the use of condenser
sheet in the backlight.
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
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.
⑧ After the product is stored under condition of low temperature or dark place for a long time, the
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.
