A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools and entertainment venues. Depending on the working method, there are different types such as CRT, LCD, and DLP.

The electron beam moves from top to bottom while scanning horizontally. This process is called vertical scanning. Each scan forms an image. The number of scans per second is called the vertical scanning frequency. The vertical scanning frequency is also called the refresh frequency, which indicates the number of times the image is refreshed per second. The vertical scanning frequency is generally not less than 50Hz, otherwise the image will flicker.

Enterprises conduct quality inspections on each link and process in the production process to ensure that unqualified raw materials are not put into production; unqualified semi-finished products are not sent to the next process; and unqualified products are not shipped out of the factory. The product inspection system reports and feeds back quality inspection information to the enterprise in a timely manner, providing a basis for the enterprise to study and solve product quality problems, thereby continuously improving and improving product quality, and improving the economic and social benefits of the enterprise.

Product quality inspection reports can comprehensively and objectively reflect the quality information of products, and are generally completed by third-party professional inspection agencies independent of both supply and demand parties. Third-party professional inspection agencies have relative independence and impartiality, and are qualified to issue fair data (inspection reports) to the society.
