PP4 stand for Picture Pitch 4.0mm, designed and developed by R&D team of LAN Display for virtual technology display to create nice effect, contrast and details for LED Screen. View distance more then five meters, the contrast of PP4 can create better colors effect then normal P4, and not damaging the details effect of the pictures or video. This is the result of PP4 placement of the SMD lamp in diagonal position, makes black area of the screen larger then normal P4 screen, and increase the contrast of the screen.
Normal P4 create more grey or white screen then its natural colors, but use PP4 the colors will looks more naturals. The lamp arrangement in diagonal position creates black effect to the screen, and at the same time, at distance farther then 5m, the good details similar to P4 will have no difference.
With higher contrast compare to the normal P4, the virtual diagonal PP4 can fight against sunlight better. The pictures and colors will be better and more clear, because the white effect from the SMD Lamp reduce by the black surface, and also PP4 screen reflection from the sunlight is less then the normal P4.
