Product Specification
M270DTN01.5
Note 7-2: ∆Vs (Max.) = ∆VF X LED No. (one string);
a. ∆VF: LED chip forward voltage deviation; (0.2 V , each Bin of LED VF)
Note 7-3: PBLU (Typ.) = Vs (Typ.) X Is (Typ.) X 4 ; ( 4 is total String No. of LED Light bar)
PBLU (Max.) = Vs (Max.) X Is (Typ.) X 4 ;
Note 7-4: Definition of life time:
a. Brightness of LED becomes to 50% of its original value
b. Test condition: Is = 120mA and 25℃(Room Temperature)
Note 7-5: Recommendation for LED driver power design:
Due to there are electrical property deviation in LED & monitor set system
component after long time operation. AUO strongly recommend the design value of
LED driver board OVP (over voltage protection) should be 10% higher than max. value
of LED string voltage (Vs) at least.
Note 7-6: AUO strongly recommend “Analog Dimming” method for backlight brightness control
for Wavy Noise Free. Otherwise, recommend that Dimming Control Signal (PWM
Signal) should be synchronized with Frame Frequency.
