Test Method
Input RAMP signal 0.7 Vp-p from pin 68.
Set subcontrast data to maximum.
Set subaddress (15) data to (08).
4. Set subaddress (09) data to (81).
5. Monitor pin 14 and measure amplitude of the intersection point of blue stretch γ OFF and
blue stretch γ ON according to the figure below. Calculate pin 14 output amplitude in IRE as
setting positive amplitude at pedestal level of output signal to 2.3 Vp-p = 100 IRE.
6. Set subaddress (1A) data to (C4), (C8), and (CC). Repeat the step 5 above. (BLγ2, BLγ3, and
BLγ4)
