Researchers in the industry and in the academic field have dedicated their efforts to overcome the difficulties of Micro LED display technologies. Currently the bottlenecks of the technology lie in six major areas including mass transferring process, the production of epitaxial wafer, method for full-color display, driver IC design, backplanes and testing and repair technology. One of the articles awarded with honorable mention in the Micro LED Technology Research Contest hosted by LEDinside has focused on the method for full-color display. The article, titled “Q...

The new display technology Micro LED actually has a history of over a decade. After Apple acquired LuxVue Technology, it officially became famous. Its properties- high resolution, high brightness, real-time response, and low power consumption- win hearts of many A-list high-tech companies such as Apple, Sony, Google and Facebook, as well as companies in the display industry.

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.

Nanoco Group, a world leader in the development and manufacture of cadmium-free quantum dots (CFQD® quantum dots) and other nanomaterials, announced it has signed a worldwide material supply and licensing agreement with Merck, a leading science and technology company. The license allows Merck to immediately start marketing Nanoco’s CFQD quantum dots and to ultimately establish its own production facility to meet growing market demand for this innovative, heavy metal-free material.

Materials researchers at North Carolina State University have fine-tuned a technique that enables them to apply precisely controlled silica coatings to quantum dot nanorods in a day – up to 21 times faster than previous methods. In addition to saving time, the advance means the quantum dots are less likely to degrade, preserving their advantageous optical properties.

Harnessing the power of the sun and creating light-harvesting or light-sensing devices requires a material that both absorbs light efficiently and converts the energy to highly mobile electrical current. Finding the ideal mix of properties in a single material is a challenge, so scientists have been experimenting with ways to combine different materials to create "hybrids" with enhanced features. 

In an industry first, TCL today introduced a 55-inch full-gamut 4K UHD TV with a manufacturer’s suggested retail price at one-third the cost of comparable OLED color televisions. All consumers of entertainment, whether for gaming, movies or other programming, can now enhance their viewing experience with deeper, sharper and more natural color at an accessible price.

Quantum Materials Corp. announced it has placed purchase orders for the proprietary equipment necessary to  commence increased production of inorganic quantum dots. The equipment is scheduled for delivery and deployment, on or before the end of the third quarter of 2014. In recent news, QMC announced obtaining equipment funding and reporting that the Los Alamos National Laboratory's (LANL) Thick-Shell technology will be integrated with a variety of QMC's composite tetrapod quantum dots to develop a line of advanced high performance quantum dots.  

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.
