Abstract
A frameless hologram display module employing a modified resolution redistribution system is proposed. The frameless display modules can be aligned two-dimensionally so as to realize a large screen size. The modified resolution redistribution system is constructed by the combination of a one-lens imaging system and a lens placed on the image plane to achieve a frameless display screen. By making the magnification of the one-lens imaging system larger than unity, the screen size can be made larger than the imaging lens. The prototype module was constructed using a spatial light modulator with a resolution of 1,980×1,080 and with a pixel pitch of 8.0 μm. The horizontal resolution increased by 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 μm. The screen size of the module was 2.0 inches and the horizontal viewing zone angle was 6.3°.
