Note)

1. The measuring position is the connector of LCM and the test conditions are under 25℃, fv = 60Hz,

Black pattern.

2. The specified Icc current and power consumption are under

the Vcc = 3.3V , 25℃, fv = 60Hz condition whereas Mosaic pattern

is displayed and fv is the frame frequency.

3. This Spec. is the max load condition for the cable impedance designing.

4. The below figures are the measuring Vcc condition and the Vcc control block LGD used.

The Vcc condition is same the minimum of T1 at Power on sequence.

5. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.

6. The measuring position is the connector of LCM and the test conditions are under 25℃.

7. The current and power consumption with LED Driver are under the Vled = 12.0V , 25℃, Dimming of

Max luminance whereas White pattern is displayed and fv is the frame frequency.

8. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.

9. If Jitter of PWM is bigger than maximum. It may cause flickering.

10. This Spec. is not effective at 100% dimming ratio as an exception because it has DC level equivalent

to 0Hz. In spite of acceptable range as defined, the PWM Frequency should be fixed and stable for

more consistent brightness control at any specific level desired.

11 The life time is determined as the time at which the typical brightness of LCD is 50% compare to that of

initial value at the typical LED current. These LED backlight has 6 strings on it and the typical current

of LED’s string is base on 20mA.
