LG Display is planning to introduce a larger 83-inch 4K OLED TV panel next year, according to a report by AVCesar. A brighter OLED panel is also a possibility.
A larger 4K OLED TV
Besides the existing 48-, 55-, 65-, and 77-inch 4K OLED panels, LG Display is planning to introduce a 83-inch 4K OLED panel in 2021, according to the report. It is also currently producing 77- and 88-inch 8K OLED panels.
LG Display is the panel manufacturer who is supplying LG Electronics, Panasonic, Sony, Philips, Vizio and others with panels so there is a good chance that we will see an 83-inch 4K OLED TV next year from LG Electronics and possibly other brands.
Obviously, you should expect a 83-inch 4K OLED TV to be expensive considering the price of current 77-inch 4K OLED TVs.

A brighter OLED TV panel
The report also mentions a "high luminosity" OLED panel with peak brightness of up to around 1000 nits. It is described as being similar to the customized panel found in Panasonic's flagship OLED TVs.
However, FlatpanelsHD's sources describe it as something else; the next OLED evolution where OLED pixels take advantage of a new luminous element and composition to enable higher brightness. We have heard it described as 20% brighter (full white screen). It is another development of LG Display's OLED technology that is not related to the 83-inch panel. We have not been able to independently confirm the information so please consider it a rumor for now.
FlatpanelsHD has much more to report in January when the 2021 OLED TVs are announced. Stay tuned.
