In this paper, we describe a novel LCD display system with depth-sensing capability based on coded aperture imaging. By invisibly displaying coded aperture patterns in an LCD screen, the depth of an object can be estimated from refocused images at various depths with reconstructed multi-view images.

— In this paper, a novel multi-touch LCD architecture with hover-sensing capability is described. To detect multiple touch points and hover points simultaneously, a sensitive backlight, which is a backlight integrated with an IR sensor array, is introduced. The sensitive backlight uses visible light to display contents on a display screen and is also used to detect reflected IR light from objects on or near the display screen. The captured image from the sensitive backlight is used to extract touch and hover information. The proposed display architecture maintains the slim form factor of an LCD with no loss of display quality, while making it possible to sense multiple touches and hovers simultaneously.

In this paper, we describe a novel multi-touch LCD display architecture with hover sensing capability based on infrared sensor array. The proposed display architecture has an advantage over existing multi-touch LCD displays in that it maintains a slim form-factor of LCD displays without loss of a display quality while it is possible to sense multiple touches and hovers simultaneously.
