Test Method
Apply 6.5-V external voltage to pin 78.
2. Set subaddress (1B) data to (00).
3. Set brightness data to maximum.
4. Apply 4.5-V external voltage to pin 78.
5. Change subaddress (1B) data to (00), (04), (08), (0C), (10), (14), (18), and (1C).
Repeat the step 3 above, and measure VABL11, VABL12, VABL13, VABL14, VABL15,
VABL16, VABL17, and VABL18.
6. ABL_G1 = VABL11 − VABL10
ABL_G2 = VABL12 − VABL10
ABL_G3 = VABL13 − VABL10
ABL_G4 = VABL14 − VABL10
ABL_G5 = VABL15 − VABL10
ABL_G6 = VABL16 − VABL10
ABL_G7 = VABL17 − VABL10
ABL_G8 = VABL18 − VABL10

mode
2. Set subaddress (1B) data to (01).
3. Measure pins 12, 13, and 14 picture period voltage, V_12R, V_13R, and V_14R.
4. Set subaddress (1B) data to (02), and repeat the step 3 above. Measure pins 12, 13, and 14
picture period voltage, V_12G, V_13G, and V_14G.
5. Set subaddress (1B) data to (03), and repeat the step 3 above. Measure pins 12, 13, and 14
picture period voltage, V_12B, V_13B, and V_14B.
