Multi-Layer Display System
A innovative display system that shows images on both sides, adjusts transparency for privacy or sunlight blocking, and can be used in vehicles or buildings. It layers transparent screens with controllable opacity to deliver versatile visuals, like movies inside a car and ads outside.

Under Display Headlight
This project integrates the vehicle's headlamp and Daytime Running Lamp (DRL) into a single component. The core technology is the placement of a transparent display in front of the headlamp unit. In normal operation, this display can function as a DRL or be used for various other purposes, such as showing graphics and text information. By unifying the previously separate headlamp and DRL, this assembly dramatically increases the degree of design freedom for the vehicle's front end.
Why it was built:
Conventional Daytime Running Lamps were limited to the simple function of emitting light and offered no additional capabilities. Furthermore, because the headlamp and DRL had to be configured as separate components, it imposed limitations on vehicle design and engineering. This project was initiated to overcome these limitations. The goal was to achieve a functional expansion of the DRL by integrating display technology with the headlamp and to present new possibilities in vehicle design by unifying the two components into one.
How it was built:
To solve this challenge, the following technical approaches were used:
- Fundamental Structure: The basic structure involves placing a display "upstream"—in the path of the light projected from the headlamp .
- Display Technology: A light-transmissive display, such as a transparent OLED or Micro-LED, serves as the core component.
- Ensuring Light Transmittance: A standard OLED display's cathode layer has low light transmittance. To solve this, a light path was secured by removing a portion of the cathode that lies in the headlamp's light path during the display manufacturing process, or by designing the display so that the cathode is not deposited in that path from the start.

Challenges & Solutions:
Distortion and Scattering of Headlamp Light
The Challenge: There was a risk that light passing through the display could be distorted or scattered due to double slit interference, degrading the headlamp's primary function (light straightness).
Solution 1: A separate optical unit, such as an aspherical lens or a micro-lens array , was added to enhance the light's straightness. The micro-lens array was particularly effective at reducing scattering caused by the light's diffraction effect as it passed through the display.
Solution 2 (Passive Blocking): A simpler solution was also devised: adding a polarizing plate to physically block light from traveling in an upward direction. This method prevents upward glare without requiring an active control system.
