Note 1: It shall be applied to pixel data signal, clock signal and control Pin.
Note 2: The maximum rating is defined as above based on the temperature on the panel surface, 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 3: Do not operate at or near the maximum rating listed for extended periods of time. Exposure to
such conditions may adversely impact product reliability and result in failures not covered by
warranty.

Note 4: 1A fuse is built in the module. Current capacity for VDD power supply should be larger then
2.5A, so that the fuse built in the module (maximum) could appropriately work under the
abnormal conditions.
Note 5: For LVDS transmitter input.
Note 6: Vertical Frequency 60Hz is recommended for best optical performance in terms of flicker.

Note 1: As Fig 5.1 shown, all LEDs are controlled by the LED Driver when applying 12V VLED.
Note 2: Dimming function can be obtained by applying DC voltage or PWM signal from the display
interface CN1. The recommend PWM signal is 1KHz ~ 10KHz with 3.3V amplitude. The
brightness is increased when applied DC voltage or PWM duty of DIM Pin is decreased.
Note 3: The estimated lifetime is specified as the time to reduce 50% brightness by applying 90mA x 4
at 25 $ C .
Note 4: Fuse is built in the module, current capacity for VLED power supply should be larger than 6.25A,
so that the fuse built in the module (maximum) could appropriately work under the abnormal
conditions.

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 around 500~1000 lx, the equipment has been set for the measurements as shown in
Fig 6.1.

following equation:
Brightness of White

Brightness of Black
Note 4: The definition of response time is shown in Fig. 6.3. The rising time is the period from 90%
brightness to 10% brightness when the data is from white to black. Oppositely, Falling time is
the period from 10% brightness rising to 90% brightness.

Note 5: The definition of viewing angle is shown in Fig. 6.4. Angle I is used to represent viewing
directions, for instance, I 270 $ means 6 o'clock, and I 0 $ means 3 o'clock. Moreover,
angle T is used to represent viewing angles from axis Z toward plane XY.
The viewing direction of this display is 12 o'clock, which means that a photograph with gray
scale would not be reversed in color and the brightness change would be less from this
direction. However, the best contrast peak would be located at 6 o'clock.
