Fine-Tuning to Specific Needs
The core benefit of Amber Molecular's molecular technology is that it lets us approach a hard problem from a new direction. TADF technology has the power to change the OLED industry and the way we view light, but the materials that produce the effect are challenging to design, and finding a good emitter to pair with them is harder still. With our tuneable molecular platform and deep synthetic capabilities, we can produce the ideal paired emitter for TADF molecules that have been let down by the poor suitability of existing fluorescent emitters.
Because of humans' greater sensitivity to shorter wavelengths, a wide-emitting red phosphor will always appear more orange than its true physical peak emission. This is what forces manufacturers to use filters in current OLED devices - all the shorter wavelengths must be blocked for the light to appear red. Amber Molecular materials have 7x less perceived peak shifting due to their narrow emission, eliminating the need for filters entirely. The use of phosphorescent materials is at the heart of the cost/brightness trade-off for OLEDs, because produced light that ends up needing to be blocked by a filter is an unnecessary strain on the OLED.
The ingredients necessary to create Amber Molecular materials are widely available, and can be sourced cheaply and sustainably. Phosphorescent OLED emitters, by contrast, are based around iridium and platinum, two of the rarest elements on Earth. These rare metals are part of the reason why phosphorescent emitters are extremely expensive. These phosphors have furthermore been covered by a patent monopoly, further inflating the cost of OLEDs for non-display applications such as automotive signaling.
Amber Molecular emitters have applications beyond display. For example, most of the currently available OLED materials were designed for the RGB display industry, which means many currently known OLED designs for producing orange light rely on the combined use of a red emitter and a green emitter. An OLED is made of successive layers of organic semiconductors which deliver current to an emissive layer, so doubling the number of emitters doubles the complexity of the OLED. This in turn doubles the cost of materials to make the device stack, and increases the manufacturing defect rate. Amber Molecular orange emitters meet safety specifications using a single emitter layer.
