(See "White Side Gamma Measurement Method".)
Set V45 = V
5.0V, SW41
and V72 = 1.6V.
Then measure the gamma gain at TP15, and
label the non-inverted side as G
inverted side as G
Next, measure the gamma gain at TP15 with
V72 = 5.0V, and label the non-inverted side as
G
(See "White Side Gamma Measurement Method".)
Set V45 = V
5.0V, SW41
and V73 = 1.6V.
Then measure the gamma gain at TP17, and
label the non-inverted side as G
inverted side as G
Next, measure the gamma gain at TP17 with
V73 = 5.0V, and label the non-inverted side as
G
(See "Black Side Gamma Measurement Method".)
Set V45 = V
1.6V.
Then measure the gamma breakpoints of the
non-inverted and inverted sides at TP15, TP16
and TP17.
(See "Black Side Gamma Measurement Method".)
Set V45 = V
5.0V, SW1
Then measure the gamma breakpoints of the
non-inverted and inverted sides at TP15, TP16
