Product Specification
LP121WX4
Liquid Crystal Display
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 and White pattern.
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 as the minimum of T1 at Power on sequence.

5. This impedance value is needed for 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 and White pattern with the normal frame frequency operated(60Hz).
8. The below figures are the measuring Vled condition
12.0V
and the Vled control block LGD used.
VLED control block is same with Vcc control block.

9. The operation of LED Driver below minimum dimming ratio
may cause flickering or reliability issue. LGD LED Driver guarantee 6.0% at PWM minimum dimming ratio.
Minimum dimming ratio 1.5% is based on Lenovo’s.
10. If Jitter of PWM is bigger than maximum, it may induce flickering.
11. 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.
12. The life time is determined as the time at which brightness of LCD is 50% compare to that of minimum
value specified in table 7. under general user condition.
