Attention:
(1) The supply voltage of the external system for the open cell input should follow the definition of V
CC
.
(2) When the customer’s backlight turns on before the LCD operation or the LCD turns off before the backlight turns off, the
display may momentarily become abnormal screen.
(3) In case that V
is in off level, please keep the level of input signals on the low or high impedance. If T2 < 0, that may
CC
cause electrical overstress.
(4) T4 should be measured after the module has been fully discharged between power off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.

To avoid abrupt temperature change during optical measurement, it’s suggested to warm up the LCD module more than 45
minutes after lighting the backlight and in the windless environment.
To measure the LCD cell, it is suggested to set up the standard measurement system as Fig. 5.1. The measuring area S
should contain at least 500 pixels of the LCD cell as illustrated in Fig.5.2 (A means the area allocated to one pixel). In this
model, for example, the minimum measuring distance Z is 370 mm when T is 2 degree. Hence, 500 mm is the typical
measuring distance. This measuring condition is referred to 301-2H of VESA FPDM 2.0 about viewing distance, angle, and
angular field of view definition.

Static Contrast Ratio (CR) =
CR-W is the luminance measured by LMD (light-measuring device) at the center point of the LCD module with
full-screen displaying white. The standard setup of measurement is illustrated in Fig. 5.3; CR-D is the luminance measured
by LMD at the center point of the LCD module with full-screen displaying black. The LMD in this item is CS2000.
(2) The LMD in the item could be a spectroradiometer such as (KONICA MINOLTA) CS2000, CS1000(TOPCON), SR-UL2
or the same level spectroradiometer. Other display color analyzer (KONICA MINOLTA) CA210, CA310 or (TOPCON)

(6) Definition of viewing angle coordinate system (T H, T V):
The contrast ratio is measured at the center point of the LCD module. The viewing angles are defined at the angle that the
contrast ratio is larger than 10 at four directions relative to the perpendicular direction of the LCD module (two vertical
angles: up T
and down T V-; and two horizontal angles: right T H+ and left T H-) as illustrated in Fig. 5.8. The contrast ratio

8. Precautions
8.1 Assembly and Handling Precautions
(1) Do not apply rough force such as bending or twisting to the open cell during assembly.
(2) It is recommended to assemble or install a open cell into the user’s system in clean working areas. The dust and
oil may cause electrical short or damage the polarizer.
(3) Do not apply pressure or impulse to the open cell to prevent the damage to the open cell.
(4) Always follow the correct power-on sequence. This can prevent the damage and latch-up to the LSI chips.
(5) Do not plug in or pull out the interface connector while the open cell is in operation.
(6) Use soft dry cloth without chemicals for cleaning because the surface of polarizer is very soft and easily be
scratched.
(7) Moisture can easily penetrate into the open cell and may cause the damage during operation.
(8) High temperature or humidity may deteriorate the performance of the open cell. Please store open cell in the
specified storage conditions.
(9) When ambient temperature is lower than 10 ºC, the display quality might be deteriorated. For example, the
response time will become slow.
8.2 Safety Precautions
(1) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case of
contact with hands, skin or clothes, it has to be washed away thoroughly with soap.
(2) After the Open cell end of life, it is not harmful in case of normal operation and storage.
