Futuristic vehicle glass operating as a transparent information display

Patented technology. Korean Patent Publication No. KR 10-2846877.

Multi-Layer
Display

A window when clear.
A display when needed.

Two transparent displays and one controllable optical layer turn a single glass surface into a clear window, a privacy screen, or two independent displays.

Explore the architecture

The limitation

Glass and displays
have separate jobs.

Conventional screens face one direction. Conventional glass stays passive. Combining both usually means adding more hardware, more depth, and more compromise.

The shift

One surface can
change its role.

The layered system coordinates transparency and imagery so the same panel can reveal, conceal, inform, and communicate from either side.

01

See throughPreserve the view when information is not needed.

02

Control privacyReduce visibility, sunlight, or glare on demand.

03

Address both sidesDeliver independent content to different viewers.

The architecture

Three active layers.
One adaptive surface.

The invention places a transparency control layer between two transparent displays, then coordinates their pixels and optical state as one system.

Exploded technical view of two transparent displays around a central transparency control layer
  1. 1

    Transparent display A

    Presents information toward the first viewing side while preserving the optical path through the panel.

  2. 2

    Transparency control layer

    Switches between clear and opaque states—globally or by region—to manage visibility, contrast, sunlight, and privacy.

  3. 3

    Transparent display B

    Faces the opposite direction and can mirror, reinforce, or independently change the information on display A.

Four operating states

The same glass.
Different behavior.

Software coordinates the display and optical layers so the panel can move between states without changing its physical structure.

Four glass states showing transparent, privacy, dual-sided, and zoned display modes

01

Transparent mode

Displays off. Optical layer clear. The surface behaves like ordinary glass.

02

Privacy mode

The middle layer turns opaque to block visibility and reduce glare or sunlight.

03

Dual-sided mode

Each display shows different content while the opaque layer separates both viewing sides.

04

Zoned mode

Selected regions display information or turn private while the rest remains transparent.

Local control

The panel does not switch once.
It responds by zone.

Display regions can be controlled more finely than the transparency layer. One area can carry information while another stays open to the world.

01

Region mapping

Groups of display pixels align with larger optical zones for practical local control.

02

Pixel overlap

Aligned imagery on both display layers can reinforce the same image and increase brightness.

03

Coordinated logic

Content, transparency, and viewing direction change together instead of operating as separate components.

Where it fits

Applications

  • Mobility glassWindows, roofs, and partitions that inform without obstructing the view.
  • Architectural surfacesFacades and rooms that shift between openness, shading, and privacy.
  • Retail & transportPublic-facing information with clear sightlines when content disappears.

Multi-Layer Display System turns glass from a passive boundary into a programmable interface.
