Ok guys, I re-test the display without the video signal. I have a blank screen <--- that look normal, I think...
Here the test :
Sharp LQ6AN101 LCD panel Display
Pinout : Power Line
+12 V = 12 V
+ 5 V = 5 V
GND = 0 V
R - Red signal - analog - video composite
G - Green signal - analog - video composite
B - Blue signal - analog - video composite
syn - Synchronization signal - analog - video composite
CON - 0 to 5 V - Contrast
BRI - 0 to 5 V - Brightest
P / N - High - 5 V --> NTSC Low - 0 V - PAL
So, to make it work, I need the video signal. VGA signal, yes for the R-G-B, but the syn signal is another matter.
I hope this info will help.
Anyway, I assuming LCD panel has the same pinouts and work on the same principle. I have two more LCD panel from laptop computer. Making small VGA display for the PC or to use with the Arduino or my DIY small LCD flat sreen TV.
On a side note, the portable DVD player with the LCD display don't work, but the Video & audio output signal work just fine, without the LCD panel.
I may fine some use for the DVD after all, but without a remote, it will be some inconvinience to use the player. Or harvest the parts.
