Rapid Assembly of Quantum Dots for MicroLED Micro-Displays

Inorganic microLEDs are the next big thing in displays, not as backlights for LCDs, but like OLEDs, as the actual light emitting pixel elements, ranging from applications in Micro-displays for Augmented /Virtual Reality (AR/VR) to wearables such as Smartwatches and Cellphones. Unlike OLED displays, however, they are far more robust and long-lived, and most importantly, far more efficient and much brighter, making them viable even for larger displays, such as video walls in advertising and in cinema in place of projection.  But to make the technology cost effective, manufacturing challenges abound, particularly as pixel sizes shrink in next generation micro-displays. For example, various coatings must be rapidly deposited in a precise, controlled manner, such as the Quantum Dots (QDs) integrated with the LEDs used in larger displays either to sharpen the color characteristics of traditional phosphors, or fully replace them in micro-displays, relying solely on QDs for color conversion. Better technology is needed for reliably depositing the various costly materials used, and even for rapidly assembling or arraying the microLEDs themselves.

Rethinking Exposure to Saturated Colored Light

Two key physical properties of light participate in color vision: wavelength and power. They factor into a light source’s spectral power distribution, which describes the amount of light power at each wavelength in the visible spectrum (which ranges from approximately 380 nanometers to 780 nanometers) that is emitted by that particular source. Power is a measure of the amount of light from each wavelength that arrives at a defined location per unit time.

Lasers Let LED Makers Pursue Augmented Reality, New Markets …

Augmented Reality (AR) is thought by many, including many of the leading CEOs in Silicon Valley, to be the “next big thing,” ultimately displacing our smartphones with stylish, interactive glasses that communicate with the digital world, in part by superimposing virtual images on the wearer’s field of view. Huge investment is pursuing this vision, much of it focused on micro-displays and sophisticated optics for overlaying images onto a wearer’s view. But just as promising is the idea of scanning such images directly into the human eye. Needed are very low power lasers or laser arrays in RGB or more colors that can be packaged in very small, discreet form factors suitable for integration into attractive, fashionable eyewear. Such lasers do not yet exist, but a technology that meets the challenge is in development, which can also lever the existing manufacturing infrastructure for LEDs. It can also address many other applications in emerging bio-tech and even in SSL markets for highly directional lighting.

An LED-Based Device for Imaging Radiation Induced Skin Damage

To eradicate any cancer cells that may potentially remain after surgery or chemotherapy, many breast cancer patients also undergo radiation therapy. All patients experience unfortunate side effects including skin irritation, and sometimes peeling and blistering. Patients can also develop permanent discoloration of the skin and thickening of the breast tissue months, or even years, after treatment. There is currently no method to predict the severity of these acute and late effects, and even current evaluation of these effects are based on subjective scoring.

Challenges In OLED Research and Development III: Solution-Based Materials

Solution based materials are a different way of processing the conventional OLED materials. So conventional OLED materials are processed by vacuum thermal deposition or heating up a powder in a crucible and evaporating it onto the substrate. Solution process materials are dissolved in a variety of solvents and then they can be coated by spin coating for lab sized experiments, or ink-jet printing, or slot-die coating, or a variety of other printing methods.

Challenges In OLED Research and Development II: Light Extraction

Light extraction is the process of removing light from the device itself. So when the device emits a photon, it gets trapped in the glass, in the organic layers themselves in the metals. And the-- what our challenge is, is to get all of that light into the viewing angle. So that when somebody sees the OLED they're seeing the full efficiency of that device. Rather than having light lost in the various segments.

Challenges In OLED Research and Development: Emitters

The thing that actually converts electricity into light is the emitter itself. So there are a number of scientific challenges that are still out there in OLEDs, particularly in emitters. Even though you can go to the cell phone store and buy yourself a cell phone that's powered by OLED emitters, and active matrix OLEDs are present in cell phones and in televisions, and it leads people to think that all of the issues are solved.

OLED R&D CHALLENGES

OLEDs are based on organic (carbon-based) materials. Unlike LEDs, which are small point sources, OLEDs are made in sheets that provide a diffuse-area light source. While developing rapidly, OLED technology is less mature than LED technology, whose rapid advancement has created a moving target for OLED products in terms of lighting performance and pricing. Still, OLED manufacturers are optimistic that with a few key breakthroughs, OLEDs will offer a value proposition complementary with LED lighting approaches.

LED R&D CHALLENGES

Like any new technology, LED lighting must demonstrate a compelling value to buyers before it begins to win sizeable market share from the incumbent technologies it will replace. Over the past decade, research and development have yielded impressive improvements in the cost, color performance, light output, efficacy, reliability, lifetime, and manufacturability of LED products. Looking at LED packages specifically, the cost in dollars per kilolumen ($/klm) has been declining rapidly since 2005 at a rate of around 20% per year. As a result, LED lighting products have become competitive in almost every lighting application, but there is still room for improvement.
