Fine pitch active led video wall light bleeding issue!
For a 0.9 mm cob dvled video wall, vendor has done physical installation but the modules are not perfectly aligned, leading to light bleed at joints which is more noticeable when we have horizontal or vertically scrolling pixels/image/test-pattern. Normally, by adjusting the magnet levels it should be done. But, OEM is saying this much is only possible as it is 0.9mm pixel pitch. I am not convinced with this explanation. What are your observations in similar cases? Are some laser, etc related tools used professionally to resolve this or how is it done otherwise?
