6. Module optical specification
1) Contrast Ratio(CR) is defined mathematically as :
CR = Surface Luminance at all white pixels / Surface Luminance at all black pixels
It is measured at center 1 point.
2) Surface luminance is determined after the unit has been ‘ON’ and 3minutes after lighting the module in a dark environment at
25°C ± 2 °C. Surface luminance is the luminance value at center 1 point across the AMOLED surface 50 cm from the surface with
all pixels displaying white.
3) The variation in surface luminance , d WHITE is defined as :
- d WHITE(9P) = Minimum(Lon1,Lon2,..., Lon9) / Maximum(Lon1,Lon2..., Lon9)
Where Lon1 to Lon9 are the luminance with all pixels displaying white at 9 locations.
4) Image sticking
When it changes into pattern-B after a 1 hour drive by pattern-A, it disappears within 5 seconds.
