I am currently working on a prototype connecting a SOC-board (Samsung ARTIK530) to a LVDS LCD display (DT070BTFT-PTS1).
The display shows a very (!) distorted picture.
I have tried fixing it using software configuration in the Linux driver with no result. The SOC comes with a predefined LCD configuration which exactly matches the timings of my LCD, so I am rather confident that the software side is ok.
The prototype connects the LVDS output of the SOC and the LCD-display using free-floating enameled copper wire.
- Can a LVDS generally produce a "rather" correct image using this kind of wiring? Or is a LVDS twisted-pair connection mandatory?
- I have tried to visualize the LVDS signals using an oscilloscope, with no success. How can LVDS signals be best measured using an oscilloscope?
UPDATE: I narrowed it down to a hardware/soldering issue. As it showed, the LCD is able to display a correct image even with the free-floating LVDS wiring.
