3.2 APPLICATION AND OTHERS
(1) This LCD module was designed and manufactured to be used in an air-conditioned room away from
direct sunlight.
(2) This LCD module cannot be applied to an instrument which requires extremely high reliability and
safety from its functions and precision. These instruments include medical equipment which affects
life- and/or wealth-support apparatus.
(3) Any problems caused by a use with deviation from the conditions mentioned in this specification are
not included in the warranty.
(5) Maintenance
This LCD module and the aforementioned data may be changed without notice. When you demand
maintenance parts, please inquire about the changes in advance.
(5) Repair
We will replace or repair all defective modules if the relevant defect is caused by KOE. However, we
will not take any responsibilities for defective modules after the expiration of warranty period. Also, if
you access the modules for repairs, we will not warrant them either even if it is within the warranty
period.
(6) Items in this specification may be changed for improvement without prior notice. Please consult our
sales division before engineering an instrument with this LCD module.
(7) When a question arises concerning the specification, please contact our sales division.

Note 1: The rating is defined for the signal voltages of the interface such as DCLK, DTMG, and RGB
data bus.
Note 2: The maximum rating is defined as above based on the chamber temperature, which might be
different from ambient temperature after assembling the panel into the application. Moreover,
some temperature-related phenomenon as below needed to be noticed:
- Background color, contrast and response time would be different in temperatures other than
25 $ C .
- Operating under high temperature will shorten LED lifetime.

Note 1: The rating is defined for the signal voltages of the interface such as DTMG, DCLK and RGB
data bus.
Note 2: An all white check pattern is used when measuring IDD. f v is set to 60 Hz.
Note 3: 1.0A fuse is applied in the module for IDD. For display activation and protection purpose, power
supply is recommended larger than 5.0A to start the display and break fuse once any short
circuit occurred.

Note 1: As for Vbc, it is recommendable to use more than 1.0V.
If Vbc is set less than 1.0V in which brightness becomes less than 20% to the maximum,
display image may look unstable since relative change of brightness tends to become large
by the slight drift of Vbc.
Note 2: Brightness rises almost linearly by increaseing the Vbc in less than 3.0V.
However, brightness is saturated when Vbc exceeds 3.0V.
Note 3: Brightness is almost proportional to the on-Duty ratio of PWM signal input.

6. OPTICAL CHARACTERISTICS
The optical characteristics are measured based on the conditions as below:
- Supplying the signals and voltages defined in the section of electrical characteristics.
- The backlight unit needs to be turned on for 30 minutes.
- The ambient temperature is 25 $ C ,VDD=12.0V,fv=60Hz.
- In the dark room around 500~1000 lx, the equipment has been set for the measurements as shown in
Fig 6.1.

Note 4: The Contrast Ratio is measured from the center point of the panel, P5, and defined as the
following equation:
Brightness of White
CR
Brightness of Black
Note 5: The definition of response time is shown in Fig. 6.3. The rising time is the period from 10%
brightness to 90% brightness when the data is from black to white. Oppositely, Falling time is
the period from 90% brightness rising to 10% brightness.
