Gamma black side

162 breakpoint difference

between R, G and B

∆PGBT

(See “Black Side Gamma Measurement Method”.)

Set V45 = VI, V23 = 1.6V, V68 = 5.0V and V77 = 3.3V.

Then measure the gamma breakpoints at TP15,

TP16 and TP17 and label the non-inverted side

as PGBRT, PGBGT and PGBBT, and the inverted

–0.15 0 0.15 V

side as PGBRTA, PGBGTA and PGBBTA, respectively.

∆PGBT = PGBRT (A) – PGBGT (A)

= PGBGT (A) – PGBBT (A)

= PGBBT (A) – PGBRT (A)

(See “Black Side Gamma Measurement Method”.)

R gamma black side

163 breakpoint sub adjustment ∆PGBR1

Set V45 = VI, V23 = 1.6V, V68 = 5.0V, V77 = 3.3V,

SW78 → ON and V78 = 1.6V.

Then measure the gamma breakpoint at TP15, and

label the non-inverted side as PGBRN and the

inverted side as PGBRNA.

∆PGBR1 = PGBRN (A) – PGBGT (A)

R gamma black side

164 breakpoint sub adjustment ∆PGBR2

range (2)

Next, measure the gamma breakpoint at TP15 with

V78 = 5.0V, SW1 → ON and V1 = 4.0V, and label

the non-inverted side as PGBRM and the inverted

side as PGBMA.

— –0.3 –0.15 V

∆PGBR2 = PGBRM (A) – PGBGT (A)

(See “Black Side Gamma Measurement Method”.)

B gamma black side

165 breakpoint sub adjustment ∆PGBB1

range (1)

label the non-inverted side as PGBBN and the

inverted side as PGBBNA.

∆PGBB1 = PGBBN (A) – PGBGT (A)

Next, measure the gamma breakpoint at TP17 with

B gamma black side

166 breakpoint sub adjustment ∆PGBB2

range (2)

V79 = 5.0V, SW1 → ON and V1 = 4.0V, and label —

the non-inverted side as PGBBM and the inverted side

as PGBBMA.

Minimum RGB gamma

167 white side breakpoint value PGWN

(See “White Side Gamma Measurement Method”.)

Set V45 = VI, V23 = 1.6V, V71 = 5.0V, V74 = 5.0V,

SW41 → ON and V41 = 1.6V.

— –0.35 –0.05 V

Then measure the gamma breakpoints of the non-

inverted and inverted sides at TP15, TP16 and TP17.

(See “White Side Gamma Measurement Method”.)

Set V45 = VI, V23 = 1.6V, V71 = 5.0V, V74 = 1.6V,

Then measure the gamma breakpoints of the non-

inverted and inverted sides at TP15, TP16 and

TP17.

Gamma white side

169 breakpoint difference

between R, G and B

(See “White Side Gamma Measurement Method”.)

Set V45 = VI, V23 = 1.6V, V71 = 5.0V, V74 = 3.3V,

SW41 → ON and V41 = 1.6V.

Then measure the gamma breakpoints at TP15,

∆PGWT
