We are pleased to announce that using the TOUCHBGA GM490 station and CCD camera enlargement, we have successfully carried out the process of replacing the LEDs on the YAMATEI panel made in 4K technology.
The size of the LEDs in the case of 4K resolution is 1×1 mm (for HD 3×3 mm). Both types of LEDs are shown in the photos below.
The YAMATEI panel shown in the photos is the smallest part of segment event displays.
We attach photos from the replacement process and a comparison of the size of the match and HD and 4K LEDs.
