Transparent organic light-emitting diode, TOLED
Once a sci-fi novelty, transparent displays are quickly moving off movie sets and into the real world.
Built on traditional LED technology, OLEDs are composed of semiconductors that emit light when an electric current is passed through them, just like LEDs, the difference comes from the organic materials used in the diodes.
OLED offers additional benefits such as flexibility, faster response times, and enhanced color displays, making it a great solution for displays in transportation, virtual meeting spaces, and gaming.
TOLED(Transparent Organic Light Emitting Diodes) are characterized by their transparency. They consist of a transparent component that includes an indium tin oxide (ITO) electrode and a layer of organic substrate, typically made of glass or plastic and placed between the cathode and anode. Bottom-emitting TOLEDs (somewhat self-explanatory) emit light from the bottom of the device and can be used to create transparent displays that enable privacy.
A departure from traditional OLEDs, transparent organic light-emitting diodes are helping to create transparent displays, some of which are some of the most innovative display creations on the market.
Privacy and connectivity reimagined with transparent displays
There are significant benefits to transparent screens.
Basically, by using bright organic light emitting diodes, we can display information on one side of the glass, while still being able to clearly see each other on the other side.
This allows you to create a built-in ad pane that functions as a window while showing content.
They are also considered more efficient and lighter, making them ideal for applications where weight and energy use are a consideration, such as transportation HUDs, where weight is important when manufacturing high-speed vehicles.
The transparent display market is growing. It was valued at $3.1 billion in 2023 and is expected to reach nearly $15 billion by 2032. As with many rapidly evolving technologies, we're starting to see transparent displays making their way into homes, with TV giant LG announcing the launch of a transparent TV screen at this year's CES show.
The dilemma of privacy is becoming increasingly important as we expect to extend our reach into consumers' homes. This is where bottom-emitting TOLEDs come into play, and the technology allows for a one-way mirror-like view, giving you more control over the level of privacy in a transparent display.
And in our digitally-driven world, virtual privacy is just as important as physical privacy. Bottom-emitting transparent technology can help you comply with GDPR measures across virtual platforms.
Bottom-emitting TOLEDs minimize diffraction of light. It delivers light directly to the display viewer and results in brighter colors and higher screen resolution in the image. It also means that content is visible from one side but remains transparent from the other. If a window is replaced with a bottom-emitting display, the view from inside the building is unrestricted, but the only visual available to people outside is the content on the screen.
One-way displays support GDPR regulations while giving you the option to have natural, friendly conversations in online meetings. For example, participants can avoid eye contact and protect sensitive data that is often shared in meetings or presentations.
