32 / 39 page

Product Specification

M270DTN01.5

Note 7-2:

Vs (Max.) = VF X LED No. (one string);

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.
