Samsung Electronics held a press event in China, launching its 2024 microLED TV lineup (in addition to its QLED and OLED TV ranges). The 2024 microLED TV lineup includes four 4K TV sizes, ranging from 76- to 114-inch.

Samsung says that it improved its microLED TV technology, offer enhanced contrast (using a new unexplained technology called 'micro-contrast technology') and color accuracy. The microLED TVs offers built-in 6.2.2 Dolby Atmos sound, and Samsung's latest NQ8 AI Gen 3 AI chipset. Interestingly, Samsung published the retail price of its microLED TVs:

Researchers from Stanford, led by prof. Zhenan Bao, developed skin-like stretchable electronic devices, using ag new design and fabrication process. The researchers say that the newly developed methods enable devices that are five time smaller and one thousand faster than their previous devices.

The new stretchable devices are powerful and fast enough to drive microLEDs, and indeed the researchers demonstrated driving 60Hz microLED arrays. The devices can also be used to drive sensors.

Micro light-emitting diode (microLED) technology is the bright young thing in the display world, literally and figuratively. Its high luminance, sharp contrast, and vivid colors, among other attributes, make this one of the most dynamic emerging technologies for next-gen display applications. We’re just beginning to see what the future holds for microLEDs and their potential impact on display and imaging capabilities.

On the Technology Fast Track 

MicroLEDs have made rapid advancements since they were first submitted for patent in 1998. The Kansas State University researchers who developed these miniaturized versions of LEDs envisioned using them in sensors, detectors, and mini-displays. But now, in just under three decades, many major display leaders and emerging companies are racing to produce and integrate the technology in everything from smartwatches to TVs to automotive displays. 

Hilton Waikiki Beach in Hawaii installed a new 146-inch Samsung The Wall microLED display in the lobby bar. The hotel management chose the high-end display in an effort to enhance the guest experience while attracting more local foot traffic.

The hotel's  howner says that the stunning visual clarity and unparalleled contrast convinced him to adopt the new microLED display. The 146-inch screen will be used to show sports, news or videos of island scenery.

Samsung Electronics is demonstrating its first transparent microLED display, showing how it compares to transparent OLEDs and LCDs:

As the aperture ratio of microLED displays is much higher than that of OLED displays or LCDs, it is able to achieve a much higher transparency. 

According to new reports from Korea, Samsung Electronics decided that from now on, Samsung Display will handle all OLED microdisplay projects, while Samsung Semiconductor (SSI, or specifically, the Compound Semiconductor Solutions team) will handle all microLED microdisplay development.

Samsung sees OLED microdisplays as the solution of choice for next-generation VR headsets, such as Apple's Vision Pro (that uses 1.4" 4K OLED microdisplays made by Sony), while microLEDs will power the more demanding AR applications.

Samsung, Sony, LG and others are producing commercial microLED panels, mostly for ultra-premium, signage and commercial applications. The ultra-large size displays are made from small microLED modules, seamlessly tiled together.

MicroLED technology makes it possible to connect two tiles in a way that retains exactly the same pixel pitch even at the tile connection (this is something that is challenging to do with OLED or LCD displays). When the displays are active, it is indeed very difficult to spot the seam. When the display is completely black however, this is not the case, and the seams are visible, and the different modules (which are never 100% aligned) reflect light a bit differently which creates a mosaic-like image.

Samsung Electronics announced that it has installed a 255-inch microLED The Wall display at Lucid Motors' design studio, to enhance the collaborative design process for their future electric vehicle models.

Lucid's design managers explains that the microLED displays enables the to visualize the future of its vehicles in high resolution at all stages of development. The extremely large displays enables designers to view cars in a 1:1 true-to-life scale, with true-life color reproduction to create a realistic rendering of a new car design.  

The school of public communications at Syracuse University has installed five Samsung The Wall microLED signage screens, to provide a "vibrant visual canvas for showcasing student accomplishments and the university’s learning environment", and to help prospective students envision their future at Syracuse University.

The displays were installed at the school's Dedication Hall, which is in the Newhouse 1 building and is the starting point for Newhouse School tours. We do not know what is the size of each of these displays.

Samsung Display announced that it has developed a 0.25" 1920x1080 (FHD) microLED microdisplay, targeting AR applications. The company did not disclose more information about this new display.

We reported that SDC has started to develop microLED microdisplay technologies in August 2022. According to our information, Samsung targets AR devices with its microLED microdisplay technology, while it targets VR devices with its OLED microdisplays.
