Display with Off-State Transparency - A simplified explanation of the abstract

This abstract first appeared for US patent application 18328262 titled 'Display with Off-State Transparency

Simplified Explanation

The patent application describes an electronic device with a projection display that appears invisible when turned off. The display achieves high transparency in the off-state, creating the illusion of invisibility.

  • The projection display includes an adjustable diffuser, a spatial light modulator, a mirror, and a light source.
  • The adjustable diffuser receives images from the spatial light modulator and reflects them onto the mirror.
  • The mirror then reflects the images onto the adjustable diffuser.
  • The light source provides light to the spatial light modulator.
  • The projection display also features an adjustable opacity layer that adjusts based on ambient light levels.
  • Additionally, an adjustable reflectivity layer is included.
  • The adjustable diffuser and/or light source may be pixelated to enhance contrast in the display.

Potential Applications:

  • This technology could be used in electronic devices where an invisible display in the off-state is desirable, such as smart glasses, augmented reality devices, or automotive heads-up displays.
  • It could also be applied in retail settings for interactive displays that appear invisible when not in use.

Problems Solved:

  • The technology solves the problem of having a visible display in the off-state, which may be distracting or aesthetically undesirable in certain electronic devices.
  • It addresses the need for high transparency in projection displays to create the illusion of invisibility.

Benefits:

  • The high off-state transparency of the display creates a sleek and seamless design, enhancing the overall aesthetics of the electronic device.
  • The adjustable opacity layer allows the display to adapt to different ambient light conditions, ensuring optimal visibility.
  • The adjustable reflectivity layer provides flexibility in controlling the reflectivity of the display, allowing for customization based on specific requirements.


Original Abstract Submitted

An electronic device may include a projection display that has a high transparency when the display is turned off. The high off-state transparency may create the appearance of the display being invisible in the off-state, which may be desirable in certain electronic devices. The projection display may include an adjustable diffuser, a spatial light modulator that projects images onto the adjustable diffuser, a mirror that reflects the images from the spatial light modulator to the adjustable diffuser, and a light source that provides light to the spatial light modulator. The projection display may also include an adjustable opacity layer that is controlled based on detected ambient light levels. The projection display may also include an adjustable reflectivity layer. The adjustable diffuser and/or light source may be pixelated to increase contrast in the projection display.
