OLED vs. LCD LED: The Debate on Technological Superiority Remains Unresolved

Although OLED displays have gained popularity in recent years due to their deep blacks and vibrant colors, there are no modern references that conclusively prove they are superior to LCD LED screens in all aspects. LCD LED screens have made significant advancements, offering high brightness levels, excellent color accuracy, and greater durability, especially in environments with prolonged light exposure. Moreover, issues like burn-in in OLED and the higher cost remain important factors to consider. In various recent studies and tests, both technologies show strengths in different contexts, suggesting that the choice between OLED and LCD LED depends more on specific user needs than on a clear technological superiority. Therefore, it cannot be conclusively stated that one completely outperforms the other. 2806:103E:16:8DD0:DEB6:78E0:7932:6C6 (talk) 20:51, 19 September 2024 (UTC)

We'd need a citation to mention any of that in the article. See WP:NOR and WP:V for details. MrOllie (talk) 20:56, 19 September 2024 (UTC)

The 'Better power efficiency' section under 'Advantages' should be removed because the only reference provided, number 112, links to a webpage with no scientific rigor or accredited study on the energy efficiency of OLED displays." 2806:103E:16:8DD0:DEB6:78E0:7932:6C6 (talk) 21:12, 19 September 2024 (UTC)

LCDs have a back light, with the LCD controlling how much light comes through. OLEDs generate their own light, depending on the supplied current. That is, LCDs run with pretty much constant power, where OLEDs change the power level depending on the image. That said, one has to consider the quantum efficiency of OLED, which might be much less than LED. In any case, the efficiency will depend on the image, so one could only give an average.

Large LCD panels such as TV screens with sectorial backlighting (for example using multiple monolithic miniature LEDs) control the local intensity of the backlight according to the local image content in front. Dark image areas are less illuminated. Therefore, such LCDs don't run with constant power and have greatly reduced power consumption when the entire image is dark.--BBCLCD (talk) 07:21, 20 September 2024 (UTC)

It would be nice to have a graph detailing the market share of TV technologies over time - the individual company histories in the "company-specific applications" section all seem to have a flurry of OLED activity that ends in 2011, 2012, followed by a small handful of newer designs. My hunch is that most people reading this article want to know if OLED televisions went the way of plasma TVs, or not. -Ashley Pomeroy (talk)

Proposed summary for technical prose

I've been using Google's Gemini 2.5 Pro Experimental large language model to create summaries for the most popular articles with {{Technical}} templates. This article, OLED, has such a template above the entire article. Here is the paragraph summary at grade 5 reading level which Gemini 2.5 Pro suggested:

An OLED is like a tiny light bulb made from special layers of material. When electricity passes through these layers, they glow and create light. This technology is used to make the screens in many TVs, computer monitors, and smartphones. OLED screens can be very thin, bright, and sometimes even flexible or bendy. They are known for showing very dark blacks and vivid colors, making pictures look clear and colorful.

While I have read and may have made some modifications to that summary, I am not going to add it to the article because I want other editors to review, revise if appropriate, and add it instead. This is an experiment with a few dozen articles initially to see how these suggestions are received, and after a week or two, I will decide how to proceed. Thank you for your consideration.

I am retracting this and the other LLM-generated suggestions due to clear negative consensus at the Village Pump. I will be posting a thorough postmortem report in mid-April to the source code release page. Thanks to all who commented on the suggestions both negatively and positively, and especially to those editors who have manually addressed the overly technical cleanup issue on six, so far, of the 68 articles where suggestions were posted.

Proposed Additions to Misc. Application

Platinum Porphyrin is an interesting compound that can be used to do a couple of different things like biometrics and night vision. I want to add this section to the miscellaneous application. I have found some papers on the matter, and think that it could be an interesting application for OLED, that diversifies the content so the purposes are not limited to types of screens.
