3. Optical Specification
3.1 Test Conditions
Optical characteristics are determined after the monitor has been ‘ON’ and stable for more than 5 minutes
in a general environment at 25°C. The values specified are at an approximate distance 0 cm from the LCD
surface at a viewing angle of
φ
and
θ
equal to 0°.

6. Surface luminance is luminance value at point 5 across the LCD surface 0cm from the surface with all
pixels displaying white. For more information seethe figure bellow. LWH=Lon5 where Lon5 is the
luminance with all pixels
displaying white at center 5 location.
