Next week AUO will showcase two new transparent microLED display prototypes at SIE 2024. The first display is a large 60-inch display, and the second is a smaller 30-inch one, that includes a touch later.
AUO's new transparent microLED display prototypes feature 60% transparency, and wide viewing angles.
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.
AUO is demonstrating several new displays at CES 2024, including some new automotive microLEDs.
The first display is a new touch-enabled transparent microLED panel that is integrated in vehicle side windows. AUO did not disclose any technical specifications. In the past, AUO demonstrated many transparent microLEDs, including a 13.5" 1920x1080 panel shown in 2023, with a transparency of 55% and a high brightness of 5,000 nits. The microLEDs used in that display were 30 micron in size.
VueReal announced that it has developed and started shipping high-resolution and high-transparency microLED displays to its customers. Using the company's own MicroSolid Printing Platform, Vuereal integrates microLEDs into an active-matrix microLED display to enable high-efficiency and high quality displays with tunable transparency (from 80% to zero).
VueReal offers a turnkey platform that enables its partners and customers to develop a custom display and fabricate it at VueReal's own pilot production line. VueReal says that it is now accepting new orders for high-resolution and high-transparency displays.
We're happy to interview Yenrich, as part of our series of interviews with MicroLED Industry Association members. Yenrich, spun-off from Epistar and now part of the Ennostar group, develops mini-LED and micro-LED packaging. The company is focused on direct-view displays, both miniLED based and microLED based.
Hello! Can you introduce your company and technology?
Yenrich, a member of Ennostar, focuses on the development of Mini/Micro LED technology and products for fine pitch displays and provides customers with integrated solutions of front-end chips and back-end system applications.
Q: Can you say why you joined the microLED association and what it is you hope to achieve?
1. Learn the latest Mini/Micro LED technology and information from the MIA and get more correct product roadmap in this field
2. Understand the needs of Micro LED for AR/VR and automotive applications and technology
Taiwan-based MicroLED developer PlayNitride (a MicroLED Industry Association member) has demonstrated its latest microLED displays at Display Week 2023.
First up we have the company's tiled large-area microLED displays, called PixeLED Matrix. The company showed a 166" vertical installation, that is made from 324 modules. The total resolution is 1440x4860 (30 PPI, or a pixel pitch of 0.833 mm). This was a very nice looking demonstration.
China-based microLED display developer Sitan Technology demonstrated its latest microLED displays at Display Week 2023.
The company has developed four microLED microdisplays: 0.13" 1024x748 monochrome, 0.18" 800x600 monochrome, 0.18” 600x400 full-color and a 0.45" monochrome FHD panel. The company's 0.13" display offers a display density of 10,000 PPI (monochrome). The company also showed small transparent microLEDs.
During Display Week 2023, Seoul Semiconductor demonstrated new prototype display modules that use its WICOP microPixel technology. WICOP Pixel is a full-color one-chip vertically-stacked microLED technology that does not require wire bonding, packaging, or lens, and enables easier microLED display production.
Seoul Semi updates that its latest WICOP Pixels reach a brightness of 10,000 nits (up from 4,000 in its previous generation technology).
During Display Week 2023, Tianma demonstrated its latest microLED display prototypes - all of which are transparent displays, stating that the main application for such displays is in the automotive sector.
The first display is a 8.75" panel, offering a resolution of 880x480 (114 PPI), a brightness of 800 nits and high transparency of over 70%. The display is an active-matrix microLED produced on an LTPS backplane.
AUO has demonstrated its latest microLED displays at Display Week 2023. Most of these displays have been shown before, but this was an impressive lineup for the Taiwanese display maker, and we'll detail the displays below.
So first up we have the 13.5" 1920x1080 (163 PPI) transparent microLEDs, which AUO says is the highest-resolution transparent microLED display ever demonstrated. The display offers a transparency of 55% and a high brightness of 5,000 nits. The microLEDs used in this display are 30 micron in size.
