According to datasheet dots on TIL305 are arranged on 0.05"(1.27mm) grid. With that information I can now measure the size of a single dot. On the picture below each increment of scale represents 0.1 mm. It means that single dot is 0.4x04mm. I thought incorrectly that they were 0.6x0.6 (drawing from datasheet is more symbolic than actual representation of the part).

For my version of TIL305 I will use 0201 leds(0.65x0.35mm) rotated by 45° on 1.27mm grid.

Display showed on pictures below has marking "KOREA 8418".

And dont forget the one "dot" led in the lower left corner :) Korea 8418 means produced in calendar week 18, 1984 I guess...
