See PlayNitride's latest flexible and transparent OLED prototypes

PlayNitride demonstrated its latest Micro-LED displays at SID DisplayWeek 2019, and the following recently-published video shows the company's booth and prototypes:

So first up we have a 7.56" 720x480 (114 PPI) transparent MicroLED display, which looks very impressive. This is the same Micro-LED display that TianMa demonstrated at its own booth. Interestingly, under direct light from it seems that the display is made from tiles - but PlayNitride says that the squares are made from the stamping process, and the company is developing technology that will remove these marks.

CSoT demonstrates a 3.3" transparent Micro-LED prototype produced in collaboration with PlayNitride

TCL subsidiary China Star (CSoT) demonstrated a 3.3" 232x116 transparent Micro-LED prototype display. The display is built on an Oxide-TFT (IGZO) backplane - CSoT says that this is the first such display ever demonstrated. The transparency is around 45%.

CSoT says that it developed the display in collaboration with PlayNitride that provided the transfer technology for CSoT.

Tianma's 7.56" transparent Micro-LED prototypes developed in partnership with PlayNitride

Earlier this week China-based Tianma unveiled a new 7.56" 720x480 (114 PPI) transparent Micro-LED display prototype at SID, and the display won SID's people's choice award - the best new display technology.

Tianma today revealed that the Micro-LED prototype was co-developed with Taiwan's PlayNitride. In 2017 PlayNitride started to sample micro-LED panels and shipped samples to 10-20 potential customers. The company's chairman and CEO, Charles Li, said in June 2018 that 5-6 of these customers are continuing the developing of micro-LED modules based on these panels. Apparently TianMa is one of these customers.

Tianma developed a 7.56" highly transparent Micro-LED display

China-based Tianma announced that it has developed a transparent 7.56" 720x480 (114 PPI) Micro-LED display. The new display, which will be demonstrated at SID next week features a transparency of over 60%.

Tianma says that the new display has an ultra-thin border of less than 0.8 mm (left and right). Tianma says that such durable and long-lasting transparent displays could be very suitable for automotive applications (such as HUDs or in-window displays).

Digitimes: Micro-LEDs low aperture ratio makes them competitive for smart displays

Digitimes posted an interesting research note, in which they state that micro-LED displays may find it hard to compete with LCD and OLED displays as the market is approaching saturation.

Micro-LEDs have several advantages over other displays - high brightness, quick response time and the ability to create flexible and transparent displays (this is also true for OLEDs). However a major advantage for Micro LEDs is that the aperture ratio is only 10%, which means that there is a lot of empty space in a micro-LED display.
