Should I buy a used, display TV at an electronics supermarket?

I need to buy a TV to replace my 10 year old one. Walking through electronics supermarkets, I saw quite a few TVs labeled as being displayed at the store or used with the remaining months of warranty, with prices reduced by 30-70% compared to new products.

Another option is used TVs, with a warranty period of 5-20 months, but the price is much higher than display products. They are even displayed in front of stores to attract buyers and have quite an enthusiastic consulting team.

However, I'm still wondering whether to choose these two types because the price is really attractive compared to new products, but it's unclear how durable they are. Looking forward to experts and readers giving advice.
