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

Note 2

- Operating under high temperature will shorten LED lifetime.

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

- 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:

WhiteofBrightness

BlackofBrightness

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.
