I found this when looking for a new TV recently
To make sense of exactly what these numbers and letters mean, let’s look at each component of this year's QN95C (QE55QN95CATXXU).
Q: This reflects the panel type, with Q covering both Neo and basic QLEDs. S, meanwhile, refers to QD-OLED panels, while U denotes basic LED panels.
E: This refers to the market the TV is on sale in, in this case, Europe. N signifies it’s a TV produced for the North American market, while A is for Asia and the Middle East.
55: The first pair of numbers simply indicate the screen size of the television in question.
QN: This relates to the range - QN being the company’s Neo QLED range. S represents the QD-OLED range.
95: The second set of numbers indicates the model series. The higher the number, the more premium the TV is. Three digits refer to 8K models, while two digits relate to 4K models.
C: This refers to the year of manufacture. Samsung has skipped a number of letters in recent years but A indicates 2021, B 2022, and C 2023.
