Note 1: 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.

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 .

- In the dark room less than 1 lx, the equipment has been set for the measurements as shown in Fig 6.1. 3.3VV Hz, 60 ,25 DD Framea fCT

Note 1: The brightness is measured the average of 5 points, in Fig. 6.2(b), for the typical value.

Note 2: The brightness uniformity is calculated by the equation as below:

which is based on the brightness values of the 5 points and 13 points in active area measured by BM-5 as shown

in Fig. 6.2(a)(b).

Brightness uniformity = Max. Brightness

Note 3: The Contrast Ratio is measured from the center point of the panel, P7, and defined as the following equation:

Black of Brightness

Whiteof Brightness CR

Note 4: 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 falling to 10% brightness.

Fig.6.3

Note 5: The definition of viewing angle is shown in Fig. 6.4. Angle is used to represent viewing directions, for instance, 270 means 6 o’clock, and 0 means 3 o’clock. Moreover, angle is used to represent viewing angles from axis Z toward plane XY.

The display is super wide viewing angle version, so that the best optical performance can be obtained from every viewing direction.

11. APPEARANCE STANDARD The appearance inspection is performed in a room around 500~1000 lx based on the conditions as below:

- The distance between inspector’s eyes and display is 30±5 cm.

- The viewing zone is defined with angle shown in Fig. 11.1 The inspection should be performed within 45∘.

11.1 THE DEFINITION OF LCD ZONE

LCD panel is divided into 2 areas as shown in Fig.11.2 for appearance specification in next section. A zone is the LCD active area (dot area); B zone is the area outside of active area 0.5mm.

In terms of housing design, B zone is the recommended window area customers’ housing should be located in, Outside of B zone is C Zone ( cosmetic Specification is not guaranteed ).

12. PRECAUTIONS

12.1 PRECAUTIONS of ESD

1) Before handling the display, please ensure your body has been connected to ground to avoid any damages by ESD. Also, do not touch display’s interface directly when assembling.

2) Please remove the protection film very slowly before turning on the display to avoid generating ESD.

12.2 PRECAUTIONS of HANDLING

1) In order to keep the appearance of display in good condition, please do not rub any surfaces of the displays by sharp tools harder than 3H, especially touch panel, metal frame and polarizer.

2) Please do not pile the displays in order to avoid any scars leaving on the display. In order to avoid any injuries, please pay more attention for the edges of glasses and metal frame, and wear finger cots to protect yourself and the display before working on it.

3) Touching the display area or the terminal pins with bare hand is prohibited. This is because it will stain the display area and cause poor insulation between terminal pins, and might affect display’s electrical characteristics furthermore.

4) Do not use any harmful chemicals such as acetone, toluene, and isopropyl alcohol to clean display’s surfaces.

5) Please use soft cloth or absorbent cotton with ethanol to clean the display by gently wiping. Moreover, when wiping the display, please wipe it by horizontal or vertical direction instead of circling to prevent leaving scars on the display’s surface, especially polarizer.

6) Please wipe any unknown liquids immediately such as saliva, water or dew on the display to avoid color fading or any permanently damages.

7) Maximum pressure to the surface of the display must be less than 410 x 1.96 Pa. If the area of adding pressure is less than 1 2cm , the maximum pressure must be less than 1.96N.

12.3 PRECAUTIONS OF OPERATING

1) Please input signals and voltages to the displays according to the values defined in the section of electrical characteristics to obtain the best performance. Any voltages over than absolute maximum rating will cause permanent damages to this display. Also, any timing of the signals out of this specification would cause unexpected performance.

2) When the display is operating at significant low temperature, the response time will be slower than it at 25 C . In high temperature, the color will be slightly dark and blue compared to original pattern. However, these are temperature-related phenomenon of LCD and it will not cause permanent damages to the display when used within the operating temperature.

3) The use of screen saver or sleep mode is recommended when static images are likely for long periods of time. This is to avoid the possibility of image sticking.

4) Spike noise can cause malfunction of the circuit. The recommended limitation of spike noise is no bigger than 100 mV.



12.4 PRECAUTIONS of STORAGE

If the displays are going to be stored for years, please be aware the following notices.

1) Please store the displays in a dark room to avoid any damages from sunlight and other sources of UV light.

2) The recommended long term storage temperature is between 10 C ~35 C and 55%~75% humidity to avoid causing bubbles between polarizer and LCD glasses, and polarizer peeling from LCD glasses.

3) It would be better to keep the displays in the container, which is shipped from KOE, and do not unpack it.

4) Please do not stick any labels on the display surface for a long time, especially on the polarizer.


13. DESIGNATION of LOT MARK 1) The lot mark is showing in Fig.13.1. First 4 digits are used to represent production lot, T represented

made in Taiwan, and the last 6 digits are the serial number.

Fig. 13.1

2) The tables as below are showing what the first 4 digits of lot mark are shorted for.

3) Except letters I and O, revision number will be shown on lot mark and following letters A to Z.

4) The location of the lot mark is on the back of the display shown in Fig. 13.2
