Touch and multi-touch solutions are widespread in displays for handheld devices such as smartphones, cameras, GPS units, etc and in tablet displays. Simultaneously, autostereoscopic 3D solutions such as parallax barrier, lenticular, anaglyph and directional backlight solutions have become available. In this paper, an example of the integration of a touch solution with a directional backlight 3D solution are detailed though the combination of touch and multi-touch solutions with any autostereoscopic 3D technologies may provide a compelling, interactive, 3D display.

Autostereoscopic 3D Display Incorporating Touch


Touch and multi‐touch solutions are widespread in displays for handheld devices such as smartphones,  cameras, GPS units, etc and in tablet displays. Simultaneously, autostereoscopic 3D solutions such as  parallax barrier, lenticular, anaglyph and directional backlight solutions have become available. In this  paper, an example of the integration of a touch solution with a directional backlight 3D solution are  detailed though the combination of touch and multi‐touch solutions with any autostereoscopic 3D  technologies may provide a compelling, interactive, 3D display.   


Various conventional and proprietary touch and multi‐touch solutions have been incorporated into a  wide range of displays as discussed in Ref. 1‐3.  There have also been implementations incorporating  touch with 3D stereoscopic (Ref 4) and autostereoscopic (Ref 5) displays.  This paper further develops  the connection between touch solutions and 3D autostereoscopic displays using the example of a touch  panel and a 3D directional backlight autostereoscopic solution though 3D touch is not limited to these  combinations. 

Autostereoscopic 3D display solutions provide a 3D visual experience without the glasses used in  stereoscopic 3D display solutions such as shutterglasses, FPR (field patterned retarder) or active retarder  solutions.  Autostereoscopic 3D displays thus enable mobile 3D as well as at‐a‐glance 3D, e.g. 3D digital  signage and other applications in which wearing glasses will not be accepted by consumers. And as with  many display types, touch capability is desirable for autostereoscopic 3D providing benefits in  

- Virtual object interaction for immersive gaming and/or entertainment,
- Intuitive, engaging and natural, interactive user experience,
- Interactive display for both 2D and 3D images
- Functional integration of touch and 3D display control.

While the following example is drawn from a directional backlight approach to autostereoscopic 3D  displays, other forms of autostereoscopic displays including parallax barrier and lenticular in both single  view and multi‐view modalities are possible modifications to the described concept.  Also various touch  modalities such as resistive, capacitive, optical sensor, etc. in single or multi‐touch solutions can be used  providing the touch sensor is low haze and high clarity in order to produce high quality autostereoscopic  image(s)
