Here are more details on Lextar's 10.6-inch transparent microLED display prototype

Last week we reported that Ennostar Incorporation (formed by a merger of Taiwan's Epistar and Lextar in 2020) demonstrated a 10.6" transparent microLED display at Touch Taiwan 2021. We now have more information on Lextar's new display prototype.

Could  you explain what exactly is going on with these large microled displays?

I thought a microled display was standard res, eg 640 pixels wide, but around 5 - 10mm in size.

So a large "microled" display, say 200mm wide, composed of those devices, would be over 12,000 pixels across.  Clearly, from the story that's  not the case.

Could you clarify please?

Thank-you,

Graham,

I'm not sure what you mean - but there are many types of displays. Some are "tiled" and made from modules - each company with its own specifications. Some are produced on TFTs, like the one from Lextar, and are so with its own resolution/spec.

Ok, I'll try again.

The PPI is about the same as for an HD tv.

Isn't the term "microled" usually associated with a much higher resolution than that??

(Eg in a micro-display about 1cm wide, 640 pixels across, or about 1600 PPI.?)

Thanks.

Ah, I think I understand the confusion. This is a common one.

A microdisplay is indeed a display that is small (<1inch usually) and with high performance and resolution. There are many technologies that can be used to build one: LCoS, OLED, MicroLED, DLD...

MicroLEDs are displays made from small (micro) LED chips. These can be used to make displays ranging from microdisplays to ultra-large area TVs (like the Sony Canvas Display or Samsung's Wall).

Close terms, but not the same.
