LM151X2
Liquid Crystal Display
Product Specification
4. Optical Specifications
Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 30
minutes in a dark environment at 25 . The values specified are at an approximate distance 50cm from
the LCD surface at a viewing angle of
Φ
and
θ
equal to 0
°
and aperture 1 degree. The test equipment is
PhotoResearch Prichard SpectroRadiometer Model 1980B-SC or equivalent. The input signal voltage and
timing specification are V
DD
of 3.3V and VESA XGA @60Hz respectively. The input current of backlight is
8mA(F
BL
= 50KHz) at the ground terminals.
