Test Method
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68. Control drive
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Apply 5-V external voltage to pin 2.
3. Set RGB contrast data to maximum (7F).
4. Input signal 2 to pin 24. Gradually decrease picture amplitude, and measure picture period
amplitude voltage when output from pin 12 is clipped.
5. Repeat the step 4 above with the following pins: Input from pin 25 and measure output from
pin 13. Input from pin 26 and measure output pin 14.
