Laptop
The first "laptop-sized notebook computer" was the Epson HX-20, released in July 1982. It had a four-line, liquid crystal display (LCD) screen, a rechargeable battery, and a receipt-size printer, in a 1.6 kg (3.5 lb) body, the size of an A4 notebook. It was described as a "laptop" and "notebook" computer in its patent.
