TRANSPARENT DISPLAY DEVICE

Smart overview of the Invention

The transparent display device is designed to integrate a display with self-power generation capabilities. It consists of a first base made from light-transmissive material, hosting multiple light sources, and a display PCB connected via a transparent electrode. A second base covers the light sources, while a photoactive layer on either the first or second base converts sunlight into electrical energy. This layer is further covered by a third base. The device's ability to self-produce power simplifies installation by eliminating wiring needs.

Technical Field

This technology pertains to transparent display devices that operate independently through self-generated power. The device leverages advancements in display modules like OLEDs, which are known for their transparency and flexibility, making them suitable for diverse installation environments such as glass windows for outdoor advertising. Traditional installations require wiring for power, posing challenges that this invention addresses by incorporating solar power capabilities.

Innovative Solution

The transparent display includes several components: a light-transmissive first base with light sources, a display PCB at its end, and a transparent electrode linking them. A second base covers the light sources, and a photoactive layer on one side of the bases converts sunlight into energy. This energy can be stored in a battery located at the end of the first base. A transparent adhesive layer enables easy attachment to windows, with the display PCB and battery positioned on a window bezel.

Advantages

This design allows for self-generation and supply of power, removing the need for external wiring and enabling straightforward installation with fewer site restrictions. Sharing components with solar panels reduces manufacturing costs and overall thickness. The flexible design can adapt to various applications, leveraging existing transparency for dual functionality as both display and solar panel.
