Tint: line scanning rate or integration time. Tint is determined by the interval of two SPs.
Freq is the main clock frequency.
Vpavg =
∑
Vp(n)/1728
Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage of adjacent pixels
Ud = Vdmax – Vdmin
Vd is the voltage amplitude between the output video's reset level and its dark level.
Vdmin is the minimum output with LED light off.
Vdmax: maximum output voltage with the LED light off
MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 4.0lp/mm
Vmin: minimum output voltage at 4.0lp/mm
lp / mm: line pair per mm
