A frameless hologram display module employing a modified resolution redistribution system is proposed in this paper. The frameless display modules can be aligned two-dimensionally to realize a large display screen. The modified resolution redistribution system consists of a one-lens imaging system, a screen lens, and a multiple illumination system. The prototype module was constructed using a spatial light modulator with a resolution of 1,980 x 1,080, and a pixel pitch of 8.0 microm. The horizontal resolution was increased four times and the magnification of the imaging system was 2.88. The horizontal resolution was increased to 7,920 and the horizontal pixel pitch was reduced to 5.8 microm. The screen size of the module was 2.0 inches and the horizontal viewing angle was 6.3 degrees.
