There are differences between national and panasonic in their establishment time and corresponding products.

1. National is the "Fa Ka Brand" that Panasonic has used since its founding in 1918. It was not until 1961 that Panasonic Electric wanted to enter the North American market, but found that the national trademark had already been registered, so it began to use Panasonic as the Panasonic brand in the North American market. Since then, in the field of consumer electrical appliances, Panasonic's black home appliances such as televisions and video recorders have gradually begun to use the panasonic brand, while white home appliances such as air conditioners, refrigerators, washing machines, microwave ovens, and rice cookers still use the national brand.

2. Panasonic Group is the world's leading electronic product manufacturer, mainly engaged in providing advanced electronic technology and system solutions to consumers in residential space, non-residential space, mobile field and personal field. Since its founding in 1918, the company has expanded its business all over the world and has been committed to "improving and upgrading social life" and "promoting the development of world culture."
