1) Select the VDP Test Pattern signal to R1, G1, B1.
2) Press the Adjust key to select 62352 and then select

RVREF, GVREF, BVREF in adjust mode

3) Adjust the luminance of CA100 to be below 0.75Cd by

volume key.(Range : 196~ 202)

4) Exit adjustment mode by pressing Adjust key.
5) Press the IN-START key on the remote control and select

the 7050 RGB Set of adjustment mode and then press the

key.

6) Check the data value of Rcontast, Gcontrast, Bcontrast is

515, Otherwise set the data 515 by using volume key.

(4) Adjustment Sequence

1) Output 255,255,255 signal of VDP TEST PATTERN, then

display maximum WHITE PATTERN on screen.

2) Gamma Adjust Mode is display as below when select

Gamma adjust by pressing ADJ key on remote control.

*First column : R adjustment

data display

*Second column : G adjustment

data display

*Third column : B adjustment

data display

3) Change the 16 Step RGB data to select white balance

x:283, y:297(D9300K).[48inch - X:269, Y:294;11000K]

4) Measure the luminace with chanded data.
5) Set the every Gamma data of 16 step to 2.2 on the basis of

measured luminance data in 3)clause. (Max lumenance
*(n1/16)**2.2)
--- Max luminance : measured luminance data n1 : every
step unit when separating signal level to 16 step

6) Output the 240, 240, 240 (15th data in max white output

signal level) in the VDP Test Pattern, change the 15th RGB
data value to come out white valance x=283,
y=297(D9300K) and measured step luminance in 5)clause.

7) Output the 224, 224, 224 (14th data in max white output

signal level) in the VDP Test Pattern, change the 14th RGB
data value to come out white valance x=283, y=297 and
measured step luminance in 5)clause.

8) As shown above, output the VDP Test Pattern signal

(208/192/176/160/144/128/112/96/80/64/48/32/16) and
change the RGB data value of each step to come out white
balance x=283, y=294 and measured luminance in
3)clause.

10. White Uniformity Adjustment

(1) Required Test Equipments

1) Uniformity measuring equipment : Equipment which can

measure chromatiity in the whole screen

2) Set stand : 1EA
3) Remote controller for adjustment : 1EA
4) Circuit thing Jig for Adjustment (Except Driver Board Assy

of adjustment model)
--- Programmed Digital Board so that the VDP Test Pattern

can output white signal by 1level form 0 to 255 level.

(2) Equipment composition

Compose the equipment as Fig.2

(3) Preparation for Adjustment

1) Composite the equipment as shown Fig.2, and place the

set on fixation stand.

2) After inputting company channel 13, adjust colour uniformity

like Horizontal/ Vertical position adjustment of input signal
part adjustment by using remote control for adjustment.

3) After pressing IN_START key on remote control for

adjustment, select the adjustment mode 7050 Uniformity.

1. RamCtrl : s/w saving uniformity write order (Do not adjust)
2. CSHP : Horizontal start point designation --- adjustable
3. CSVP : Vertical start point designation --- adjustable
4. CEHP : Horizontal END point designation --- adjustable
5. CEVP : Vertical END point 6.designation --- adjustable
6. Mode : uniformity mode select --- adjustable if need

*** 0 : 221point & 3level ---- defalut value
*** 1 : 221point & 4level
*** 2 : 825point & 3level
*** 3 : 825point & 4level

7. KHH : Upper 2byte of horizontal line correction coefficient --

Change according to CSHP, CEHP value.

8. KHL : Upper 2byte of vertical line correction coefficient --

Change according to CSHP, CEHP value.

** How to calculate KHH, KHL value

LCD panel size = 1280 x 720
Correction Point = 221 point
--> 17 horizontal points x 13 vertical points

(16 horizontal segments x 12 vertical poins)

H Coefficient(KHH, KHL)

--> Calculation method (CEHP-CSHP=1280, Horizontal

segment value =16)

9. KVH : Upper 2byte of vertical line correction coefficient
