Talk:MicroLED

untitled
The context of the current article is very marketing focused. Comparison with LCD technology is abundant in the article, and frankly very tiring considering that people have been discussing the benefits of LED arrays over LCD displays for decades already. As such the repeat emphasis on beating LCD performance, and to some degree even that of OLEDs, feels hollow and irrelevant from an innovation/technology development perspective in this day and age. - While providing numerous challanging engineering aspects, microLED technology is nothing more than putting together hundreds to several millions of LEDs into arrays of centimeter to meter dimensions with individually controllable pixels that can be used for various applications including displays, projectors, light sources, for example. Conceptually miroLED technology is nothing more than miniaturized versions of larger LED screens developed since the 1990s for applications such as billboards and large outdoor screens.

For a technology focused article, I'd invite our engineering experts to come forward and provide some more relevant detail beyond the typical marketing jargon.

Agreed, and the claim "Inorganic semiconductor microLED(µLED) technology[20][21][22][23] was first invented in 2000 by..." is more silly self-aggrandizement. There were a great many patents on this approach before this. Broadcasting a new buzzword is not equivalent.

"edit request"
NOTE: I am proposing this edit for FleishmanHillard on behalf of Samsung. I am a paid editor for various brands and am aware of the COI guidelines.

1. Edit first paragraph to include additional information and references that define microscopic and further explain what Micro LED displays are made up of.

microLED, also known as micro-LED, mLED or µLED, is an emerging flat panel display technology. As the name implies, mLED displays consist of arrays of very small microscopic LEDs – 0.000 001 or one millionth of a stated unit – forming the individual pixel elements. When compared to the widespread LCD technology, mLED displays, comprised of RGB subpixels controlled independently, offer better contrast, response times, and energy efficiency.

2. Add a sentence at the end of the Commercialization section and link to graphics that visually show differences in micro LED technologies.

MicroLED has many commercial applications, including wearable devices, signage and automotive, and many companies are vying to develop it further. MicroLED is projected to replace sectors worth US $30-40 billion.

quanatative difference
This page needs actual quantitive differences between this technology and others. I've read a lot of OLED v MicroLED articles that make statements such as MicroLED can go brighter, have deep blacks like OLED, high viewing angles etc, but none have actual figures.

Best OLED TVs today can achieve 900nits wtih 10% white pattern, or a true 0 nit black for example. What are the comparative values for MicroLED? Someone, somewhere must know?? — Preceding unsigned comment added by 2620:104:4001:71:8C8F:64A8:E674:C585 (talk) 12:53, 20 September 2019 (UTC)

microLED > OLED for total brightness?
Is this true even as of 2020? Have OLEDs caught up or microLEDs still offer way higher brightness levels? Can an expert weigh in? xpclient Talk 07:23, 7 January 2020 (UTC)

Is microLED really aimed at small devices?
The opening says "microLEDs are primarily aimed at small, low-energy devices..." Then is goes on to say that so far, the products that are on the market with microLED's are "video walls" and "cinema screens."

It was my impression that one of the obstacles to manufacture is shrinking the LED's to get high ppi. Thus, the first expected products would be products with low PPI - display walls and cinema screens. A 20' screen showing 4k or even 8k video is still low ppi compared to a smartphone.

I'd expect the next market to be TV's, then monitors, then smartphones... for the market to start with big devices and transition to small ones.

Maybe that's not accurate... there are rumors about Apple Watch getting microLED soon. The flip side of high PPI is that with a new technology, low yield curves favor starting with smaller devices.

CNET's coverage here: Doesn't emphasize small screens at all... it says the technology may be coming to small screens, but mainly talks about TV's.

So is it accurate that "small, low energy devices" is the initial market? It seems to conflict with what we know so far... video walls and cinema screens, and soon, TV's.
