5. PCMCIA CARD Checking Method
• You must adjust DTV 29 Channel and insert PCMCIA
CARD to socket.
1) If PCMCIA CARD works normally, normal signals display
on screen. But it works abnormally, "No CA module" words
display on screen.
=> Caution: Set up "RF mode" before launching products.
6. Adjustment of White Balance
• Test Equipment
- Color Analyzer (CS-1000, CA-100+(CH.9), CA-210(CH.9) )
* Please adjust CA-100+ / CA-210 by CS-1000 before
measuring
=> You should use Channel 9 which is Matrix compensated
(White, Red, Green, Blue revised) by CS-1000 and adjust
in accordance with White balance adjustment coordinate
• Color temperature standards according to CSM and Module
• Change target luminance and range of the Auto adjustment
W/B equipment.
• White balance adjustment coordinate and color temperature
* PC (for communication through RS-232C) => UART Baud rate :
115200 bps
* Connecting picture of the measuring instrument (On
Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C IN-START -> Enter the
mode of White-Balance, the pattern will come out.
Auto-control interface and directions
1. Adjust in the place where the influx of light like floodlight
around is blocked. (illumination is less than 10ux).
2. Adhere closely the Color Analyzer (CA-210) to the module
less than 10cm distance, keep it with the surface of the Module
and Color Analyzer’s Prove vertically.(80~100°).
3. Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 15 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check
the back light on.
6. Manual white Balance
1) Press the ADJ KEY on Adjustment R/C.
Select "3. Test Pattern" by using
D
/
E
(CH +/-) and press
ENTER(
V
)
Select "White" by using
F
/
G
(VOL +/-) and press
ENTER(
V
) and heat run over 15 minutes.
2) Zero Calibrate CA-100+ / CA-210, and when controlling,
stick the sensor to the center of LCD module surface.
3) Press the ADJ KEY on Adjustment R/C
4) Select "2. White Balance" and press
G
(VOL +)
Set test-pattern on and display inside pattern.
5) Control is carried out on three color temperatures, COOL,
MEDIUM, WARM.
(Control is carried out three times)
< Temperature: COOL >
- R-Cut / G-Cut / B-Cut is set to 64.
- Control R-Gain and G-Gain.
- Each gain is limited to 192.
< Temperature: MEDIUM >
- R-Cut / G-Cut / B-Cut is set to 64.
- Control R-Gain and B-Gain.
- Each gain is limited to 192.
< Temperature: WARM >
- R-Cut / G-Cut / B-Cut is set to 64.
- Control G-Gain and B-Gain.
- Each gain is limited to 192.
* One of R Gain / G Gain / B Gain should be kept on 192, and
adjust other two lower than 192.
(When R/G/B GAIN are all 192, it is the FULL DYNAMIC Range
of Module)
