1.Color analyzer (CA-100 manufactured by MINOLTA)
2.Signal generator (ASTRO DESIGN VG-828D)

1.Dab the W/B adjustment jig (CA-100) at the glass face of the
   panel.
2.Connect the Signal generator (VG-828D) to the DVI terminal.
3. Input All-white signal (70%).
4. Make the settings as follows.

• set the quality mode to PRO.
• Set the PICTURE to MAX.
• SEt the color temp. be adjusted cool.

5. Execute the following control with UART control from the
    JIG PC.

5-1. Set as follows:

R_GAIN_OFFSET = 31
G_GAIN_OFFSET = 31
B_GAIN_OFFSET = 31
(Unnecessary because NVM has been set)

5-2. Set as follows:

R_BIAS_OFFSET = 31
G_BIAS_OFFSET = 31
B_BIAS_OFFSET = 31
(Unnecessary because NVM has been set)

5-3. Set as follows:

SUBBRIGHT_R = 920
SUBBRIGHT_G = 880
SUBBRIGHT_B = 950
(Unnecessary because NVM has been set)

5-4. Set RKOF = 0, GKOF = 0, BKOF = 0.

5-6. Adjust RKOF and BKOF with the color values inTable

2 as the target.

5-7. When RKOF and BKOF cannot be adjusted:

(a) Return the smaller one of the adjusted values to 0.
(b) Readjust with the larger value and GKOF.

5-8. When the following item is not satisfied after the above

adjustmetn, fix the smallest adjustment value at 0 and
readjust with the rest of two values.
(a) At least one of the value among RKOF, GKOF and
     BKOF is 0.

5-9. Write the values determined as a result of the above

adjustment into RKOF, GKOF and BKOF.

5-10. Adjust PDRV_SUBCONT_R and

PDRV_SUBCONT_B with the color values among the
specified values in Table 1 as the target.

5-11. When there is a value that exceeds 512 after the

adjustment.
(a) Return the larger one of the adjusted values to 512.
(b) Readjust with the smaller value and
      PDRV_SUBCONT_G.

5-12. When the following items are not satisfied after the

above adjustment, fix the largest adjustment value at
512 and readjust with the rest of two values.
(a) All PDRV_SUBCONT_R, PDRV_SUBCONT_G
     and PDRV_SUBCONT_B do not exceed 512.
(b) At least one of the value is 512.

5-13. Write the values determined as a result of the above

adjustment into PDRV_SUBCONT_R,
PDRV_SUBCONT_G and PDRV_SUBCONT_B.
