search the laptop you want to buy on the internet and check its specification to see which display the desired laptop has, whether it is LCD or LED.

If there are four digits, there are second or later generations
For example
Intel core i3.,,,, 803
That is, if three digits come after i3, it means first generation
Intel core i3.,,,, 2304
In this example, i3 is followed by four digits, so this is the second generation.
Similarly
Intel core i3.,,,, (3)405
Inter core i3.,,,, (4)505
These two examples also have four digits, but in the first example, the starting digit is 3, so it is the third generation
In the second example, the starting digit is 4, so the fourth generation
Remember that round brackets have been added to explain the first digit
