Note (2) The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 65 ºC with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature
of display area from being over 65 ºC. The range of operating temperature may degrade in case of
improper thermal management in final product design.

5.3 COLOR DATA INPUT ASSIGNMENT
The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input for the color.
The higher the binary input, the brighter the color. The table below provides the assignment of the color versus
data input.

Note (0) Light source is the standard light source ”C” which is defined by CIE and driving voltage are based on
suitable gamma voltages. The calculating method is as following :
1.Measure Module’s and BLU’s spectrum at center point. W, R,G, B are with signal input. BLU
(V290BJ1-LE1) is supplied by CMI.
2.Calculate cell’s spectrum.
3.Calculate cell’s chromaticity by using the spectrum of standard light source “C”.
Note (1) Light source is the BLU which supplied by CMI and driving voltage are based on suitable gamma
voltages.
Note (2) Definition of Viewing Angle (θx, θy) :
Viewing angles are measured by Autronic Conoscope Cono-80 (or Eldim EZ-Contrast 160R )

8. PRECAUTIONS
8.1 ASSEMBLY AND HANDLING PRECAUTIONS
[ 1 ] Do not apply rough force such as bending or twisting to the module during assembly.
[ 2 ] It is recommended to assemble or to install a module into the user’s system in clean working areas. The dust
and oil may cause electrical short or worsen the polarizer.
[ 3 ] Do not apply pressure or impulse to the module to prevent the damage of LCD panel.
[ 4 ] Always follow the correct power-on sequence when the LCD module is turned on. This can prevent the
damage and latch-up of the CMOS LSI chips.
[ 5 ] The distance between COF edge and rib of BLU is suggested to be larger than 5mm, in order to prevent
from damage on COF during module assembly.
[ 6 ] Do not design sharp-pointed structure / parting line / tooling gate on the COF position of plastic parts,
because the burr will scrape the COF.
[ 7 ] If COF would be bended during module assembly, it is suggested not to locate the IC on the bending corner
of COF.
[ 8 ] The gap between COF IC and any structure of BLU is suggested to be larger than 2mm, in order to prevent
from damage on COF IC.
[ 9 ] Bezel opening must have no burr. Burr will scrape the panel surface.
[ 10 ] It is suggested that bezel of module and bezel of TV set can not press or touch the panel surface. It will
make light leakage or scrape.
[ 11 ] When module used FFC / FPC, but no FFC / FPC to be attached in the open cell. Customer can refer the
FFC / FPC drawing and buy it by self.
[ 12 ] The gap between Panel and any structure of Bezel is suggested to be larger than 2mm, in order to prevent
from damage on Panel.
[ 13 ] Do not plug in or pull out the I/F connector while the module is in operation.
[ 14 ] Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and easily
scratched.
[ 15 ] Moisture can easily penetrate into LCD module and may cause the damage during operation.
[ 16 ] When storing modules as spares for a long time, the following precaution is necessary.
[ 16.1 ] Do not leave the module in high temperature, and high humidity for a long time. It is highly
recommended to store the module with temperature from 0 to 35кat normal humidity without
condensation.
[ 16.2 ]
[ 17 ] When ambient temperature is lower than 10ºC, the display quality might be reduced.
[ 18 ] The peeling strength of COF is 200gf/cm.
[ 19 ] During module assembly process, the static electricity around the environment should be less than 300V.

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 end of life of the open cell product, it is not harmful in case of normal operation and storage.
