OEM/ODM is the product of the high degree of division of labor in modern industry. More and more products are produced and sold in these two ways, because these two modes can more effectively integrate resources and achieve a win-win goal.

OEM (that is, ORIGINAL EQUIPMENT MANUFACTURER) means "original equipment manufacturer", which means that a company designs and produces a product according to its own specifications, and then sells it to another company for branding and distribution. In the computer manufacturing industry, OEM is often used as a verb. When people say that a company OEMs another company's product, it means that the company buys a complete and designed finished product (ie "original equipment") from another company (ie, the OEM company). Most of the time, the buyer requires the seller to only change the name and color of the product, but not to modify other aspects of the product. Only the product name and model number are different.

ODM (ORIGINAL DESIGN MANUFACTURER) means "Original Design Manufacturer", which means that a company designs and produces a product according to another company's specifications. For example, a computer company such as HP may specify specifications for a laptop computer it wants to bring to market. They will specify the appearance requirements of the product, such as the size and technical requirements of the screen, input/output ports, the forward tilt of the keyboard, the shape and color of the computer bag, the location of the speakers, etc. They also typically specify specifications for major internal details of the product, such as the CPU or video controller. However, they do not design drawings, specify the type of switching transistor used for the power supply, and do not select the frequency of the backlight converter. These are the jobs of ODM. ODMs design and manufacture laptops according to specifications put forth by computer companies. Sometimes, ODM can also be produced according to existing samples. The ODM method often pays more attention to cooperation, while in the case of OEM, the buyer basically does not participate in the specific specifications of the product.

OBM (Original Brand Manufacturer). OBM is to establish its own channels and build its own brand
