Samsung to start producing 89-inch LTPS microLED TVs in Q3 2022

Towards the end of 2020, Samsung announced it's first "consumer" MicroLED TVs (on LTPS backplanes, rather than PCB used by Samsung for its professional models), including smaller 77-inch to 89-inch models. The smaller models were scrapped later in 2021, and then Samsung further delayed its plans for "consumer" microLED TV production.

According to reports from Korea, Samsung decided to move the production of its MicroLED TVs from its Vietnam fab to its fab in Korea, and aims to start producing LTPS microLED TVs in Q3 2022. Samsung is likely to start with a 89-inch model which will hopefully ship before the end of 2022, and will carry a price tag of around 100 million Won (or around $77,000).

Innolux unveils a 12.3" tiled microLED display module prototype

Taiwan-based display maker Innolux demonstrated a 12.3" microLED tiled seamless display module prototype, based on an LTPS backplane. The display achieves a brightness of 700 nits and a resolution of 480x180 (40 PPI)

The display is driven by an active matrix backplane, and uses inkjet-printed quantum dots based color conversion system (which we do not have any more info for, as of now). The LEDs themselves are 20x40 um in size.

AUO to supply LTPS TFT backplanes to Samsung's next-generation microLED TVs

According to reports from Korea, Samsung Display recently approached AU Optronics with a request to develop a 12.7" microLED LTPS TFT backplane to be used in Samsung's MicroLED TVs.

These new backplanes will be used in Samsung's 2022 microLED TVs. This will be a change from Samsung's current microLED TVs that use printed circuit boards (PCBs), and will allow Samsung to release TVs with higher pixel densities, and thus enable smaller 4K TVs. According to the report, Samsung's plan is to launch 89-inch, 101-inch and 114-inch LTPS-based microLED TVs in 2022.

Samsung Electronics scraps its plans to release 77-inch microLED TVs in 2022

Towards the end of 2020, Samsung announced it's first "consumer" 110-inch 4K MicroLED TV, and then in early 2021 it said it will release smaller microLED TVs, including 77" and 88" models.

Tianma demonstrated new microLED technologies at SID Displayweek 2021

Tianma demonstrated several new microLED display prototypes at SID Displayweek 2021. First up is a 7.56" 720x480 (114 PPI) flexible MicroLED display, developed in collaboration with PlayNitride. The display is driven by an LTPS backplane and achieves a brightness of over 600 nits. The bending radius is 50 mm.

The second display is a tiled display that combines two 5.04" 480x320 (114 PPI) LTPS microLED displays. This one was develop again in collaboration with PlayNitride. The border (bezel) of the panel is less than 0.03 mm - although looking carefully at the display you can see a black line separating the two panels.
