A 1.
Input signal 2 from pin 66.
Test Method
2. Increase signal 2 amplitude A. Determine gamma correction point Vγ1, Vγ2,
and Vγ3 of subaddress data (14). Set subaddress (14) data as follows:
(01) − γOFF
(03) −γ1ON
(05) −γ2ON
(07) −γ3ON
Measure #12 output signal amplitude levels and chart a characteristic diagram.
3. Determine Vγ where γ starts applying and gradient ∆ at γ ON when linearity at γ
OFF is 1.
