Note :
(1) IL means the lamp current of one lamp.
(2) The voltage shown above should be applied to the lamp for more than 1
second after startup . Otherwise the lamp may not be turned on .
(3) The lamp frequency may produce interference with horizontal synchronous
frequency from the display , and this may cause line flow on the display . In
order to avoid interference , the lamp frequency should be detached from the
horizontal synchronous frequency and its harmonics as far as possible.
(4) PL = IL x VL x 2
(5) The lifetime of lamp can be defined as the time in which it continues to
operate under the condition Ta = 25±2℃ and IL =(5.5)mArms until one of the
following events occurs.
(a) When the brightness becomes or lower than 50% of its original value.
(b) When the effective ignition length becomes or lower than 80% of its
original value.(Effective ignition length is defined as an area that has less
than 70% brightness compared to the brightness in the center point.)

NOTE (1) Definition of Response Time (TR , TF)and measurement method :
NOTE (2) Definition of Contrast Ratio (CR) :
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L63 / L0
L63 : Luminance of gray level 63
L0 : Luminance of gray level 0

NOTE (4) Definition of Luminance of White( LC ) :
Measure the luminance of gray level 63 at center point
LC = L(5) ; L(X) is corresponding to the luminance of the point X at
Figure in Note(5)
NOTE (5) Definition of White Variation ( δW ) :
Measure the luminance of gray level 63 at center point
δW = Max[L(1), L(2), L(3), L(4), L(5)] / Min[L(1), L(2), L(3), L(4), L(5)]
NOTE (6) Measurement Setup
The LCD module should be stabilized at given temperature for 20
minutes to avoid abrupt temperature change during measuring. In order to
stabilize the luminance, the measurement should be executed after
lighting Backlight for 20 minutes in a windless room.

10. USE PRECAUTIONS
10-1 Handling precautions
(1) The polarizing plate may break easily so be careful when handling it. Do not
touch, press or rub it with a hard-material tool like tweezers.
(2) Do not touch the polarizing plate surface with bare hands so as not to make it
dirty. If the surface or other related part of the polarizing plate is dirty, soak a soft
cotton cloth or chamois leather in benzine and wipe off with it. Do not use
chemical liquids such as acetone, toluene and isopropyl alcohol. Failure to do so
may bring chemical reaction phenomena and deteriorations.
(3) Remove any spit or water immediately. If it is left for hours, the suffered part
may deform or decolorize.
(4) If the LCD element breaks and any LC stuff leaks, do not suck or lick it. Also if
LC stuff is stuck on your skin or clothing, wash thoroughly with soap and
water immediately.
10-2 Installing precautions
(1) The PCB has many ICs that may be damaged easily by static electricity. To
prevent breaking by static electricity from the human body and clothing, earth the
human body properly using the high resistance and discharge static electricity
during the operation. In this case, however, the resistance value should be
approx. 1MΩ and the resistance should be placed near the human body rather
than the ground surface. When the indoor space is dry, static electricity may
occur easily so be careful. We recommend the indoor space should be kept with
humidity of 60% or more. When a soldering iron or other similar tool is used for
assembly, be sure to earth it.
(2) When installing the module and ICs, do not bend or twist them. Failure to do
so may crack LC element and cause circuit failure.
(3) To protect LC element, especially polarizing plate, use a transparent
protective plate (e.g., acrylic plate, glass etc) for the product case.
(4) Do not use an adhesive like a both-side adhesive tape to make LCD
surface (polarizing plate) and product case stick together. Failure to do so may
cause the polarizing plate to peel off
10-3 Storage precautions
(1) Avoid a high temperature and humidity area. Keep the temperature between
0°C and 35°C and also the humidity under 60%.
(2) Choose the dark spaces where the product is not exposed to direct sunlight
or fluorescent light.
(3) Store the products as they are put in the boxes provided from us or in the
same conditions as we recommend.

10-4 Operating precautions
(1) Do not boost the applied drive voltage abnormally. Failure to do so may break
ICs. When applying power voltage, check the electrical features beforehand and
be careful. Always turn off the power to the LC module controller before
removing or inserting the LC module input connector. If the input connector is
removed or inserted while the power is turned on, the LC module internal circuit
may break.
(2) The display response may be late if the operating temperature is under the
normal standard, and the display may be out of order if it is above the normal
standard. But this is not a failure; this will be restored if it is within the normal
standard.
(3) The LCD contrast varies depending on the visual angle, ambient temperature,
power voltage etc. Obtain the optimum contrast by adjusting the LC dive voltage.
(4) When carrying out the test, do not take the module out of the low-temperature
space suddenly. Failure to do so will cause the module condensing, leading to
malfunctions.
(5) Make certain that each signal noise level is within the standard (L level:
0.2Vdd or less and H level: 0.8Vdd or more) even if the module has functioned
properly. If it is beyond the standard, the module may often malfunction. In
addition, always connect the module when making noise level measurements.
(6) The CMOS ICs are incorporated in the module and the pull-up and pull-down
function is not adopted for the input so avoid putting the input signal open while
the power is ON.
(7) The characteristic of the semiconductor element changes when it is exposed
to light emissions, therefore ICs on the LCD may malfunction if they receive light
emissions. To prevent these malfunctions, design and assemble ICs so that they
are shielded from light emissions.
(8) Crosstalk occurs because of characteristics of the LCD. In general, crosstalk
occurs when the regularized display is maintained. Also, crosstalk is affected by
the LC drive voltage. Design the contents of the display, considering crosstalk.
10-5 Other
(1) Do not disassemble or take the LC module into pieces. The LC modules once
disassembled or taken into pieces are not the guarantee articles.
(2) The residual image may exist if the same display pattern is shown for hours.
This residual image, however, disappears when another display pattern is shown
or the drive is interrupted and left for a while. But this is not a problem on
reliability.
