What do the letters stand for?

[starace]

I believe J or JSB stands for Shenzhen Jieshibao Technology Co.
LSB is Shenzhen Sailebao Technology Co.

I guess they are both from the city of Shenzhen.

Correct me if I am wrong.

What does KME and DSE stand for?

The reason I ask is so that if I know the manufacturers name or model then I know that the parts are the same for interchangeability and helps in comparing models from one seller to another for price comparison.

I don't know if this is what you're looking for...
