Definition:
(1) Tint: line scanning rate or integration time. Tint is determined by the interval of two start
pulses (SP).
(2) freq is the main clock frequency.
(3) Vpavg = â Vp(n)/1728
(4) Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
(5) Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the nonuniformity percentage of adjacent pixels
(6) 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.
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 4.0 lp/mm
Vmin: minimum output voltage at 4.0 lp/mm
(8) lp / mm: line pair per mm
