      displays we know today came about only after numerous additional innovations.

      Celebration at the show in Los Angeles. The celebration will feature a collection of
      LCD luminaries who have played pivotal roles in this technology. The details are
      described in our SID News feature, and the roster of speakers is not to be missed. This
      will be a wonderful chance to either reminisce if you were there for part of the history,
      or gain some perspective on how we got here and where this technology is going next.
         Some of the people who were there along the way and made crucial contributions to
      the LCD industry are recognized by this year’s SID Honors and Awards. As Jenny

         Some spectators may see this race for dominance in AR and VR display technology as

      SID Salutes Display Industry Standouts
      This year’s winners of the Society for Information Display’s Honors and Awards include
      Hidefumi Yoshida, who will receive the Karl Ferdinand Braun Prize for his contributions
      to LCD technology; Pochi Yeh, who has earned the Jan Rajchman Prize for his development
      of matrix methods for analyzing the viewing-angle properties of LCDs; Sang Wan Lee, who
      will receive the inaugural David Sarnoff Industrial Achievement Prize for his leadership and
      contributions to the growth of the display industry; Vladimir Chigrinov, who has earned the
      Slottow-Owaki Prize for his educational efforts in the field of liquid-crystal devices; and
      Seth Coe-Sullivan, who will receive the Peter Brody Prize for his pioneering contributions
      to quantum-dot technology.

      LCOS and AR/VR
      Companies are delivering different renditions of augmented-reality and virtual-reality
      products to the market, including Google Glass, Microsoft Hololens, ODG R-7, Magic
      Leap One, Oculus Rift, HTC Vive, and the Dell Visor. All these products have different
      specifications and applications. This article will discuss the differences between VR and
      AR, and how LCOS microdisplays can play an important role in making these applications
      more viable.

      cousins to VR devices, but with different
      DNA. There are several differences, but the
      main one is that VR provides an immersive
      experience for users, who experience the
      virtual world the system provides and are not
      able to see the environment around them
      (Fig. 1). AR involves a wearable device that
      allows users to view the surrounding environ-
      ment with an overlap of digital content. For
      example, a user can see his friend’s face with
      a digitally generated hat; an architect is able
      to see her newly designed building at the con-
      struction site before construction has begun;
      a field technician can follow 3D instructions
      from the other side of the world to fix a copy
      machine; a doctor can perform heart surgery
      with directions from an expert in another
      country (Fig. 2).

           coming.
         In summation, VR provides a virtual world
      to the user, whereas AR adds digital content to
      a real-world view. This is the key difference
      between these two product categories.

      Liquid Crystal on Silicon
      Liquid crystal on silicon (LCOS) is a well-
      known microdisplay technology that is widely
      used by AR headset designers due to several
      key advantages that we will discuss. The
      liquid crystal is sandwiched between a layer
      of glass and a silicon wafer (Fig. 3). The           Fig. 2: A popular AR device (which its maker refers to as a mixed-reality device) is the Hololens
      silicon wafer’s top metal layer has two key          from Microsoft. The headset at left enables augmented-reality applications, including remote
      functions: First, it is a mirror to reflect the      plumbing repairs, as shown at right. Source: Microsoft
      light, and second, the mirror’s voltage drives
      the liquid crystal, twisting it in order to create
      an image. When the polarized light reflects
      from the mirror, the light can project through
      the optical system so the user can see the image.
         LCOS has various applications in projec-
      tors, head-up displays (HUDs) for cars, and
      AR glasses. Other useful LCOS applications
      are in phase modulation for communication
      applications and holographic displays. (It
      would take another article to discuss phase
      modulation and LCOS.) LCOS projection
      systems offer one of the best image-quality
      visual systems available. Sony and JVC’s
      top-of-the-line home theater projectors both
      use LCOS as the display source. Since LCOS

      on resolution. Both 4K and 8K projection
      systems have been implemented with LCOS.
         There are several different types of these
      systems (two appear in Fig. 4):
         • The three-panel LCOS system is used
           mostly for home theater projectors. It
           uses three LCOS panels, each projecting
           in red, green, and blue light provided by
           the optical system. The system uses a
           lamp, LED, or laser as a light source.
         • The color-sequential single-panel system
           has been used in some AR glasses. The
           system consists of one LCOS panel, and
           the system projects red, green, and blue
           color fields sequentially. The optical
           system sequentially provides red, green,
           and blue light to the LCOS panel.
         • The color-filter single-panel system inte-
           grates a color filter on the top metal layer
           so that the optical system requires only
           white light as the input. This design uses
           the color filters on the LCOS panel to          Fig. 4: At left is a color-sequential LCOS optical system, and at right is a color-filter LCOS
