SJ/T 11346-2015 Electronic Projector Measurement Method Inspection Report

Projectors, also known as projectors, are devices that can project images or videos onto screens and can be connected to computers, VCDs, DVDs, BDs, game consoles, and DVs via various interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and other venues. Depending on their working method, there are different types such as CRT, LCD, DLP, and 3LCD.

Relevant Standards

On September 2, 2021, China officially released the standard for LED smart projectors, titled "Technical Specification for LED Smart Projectors" (hereinafter referred to as "the Standard"). Amidst the accelerated development of smart projection in China and the current unordered market competition, this standard fills the gap in regulations and will promote high-quality industry development. The Standard defines the intelligent technical functions and operating system features of LED smart projectors, as well as specifies related definitions, technical requirements, and testing methods for hardware systems, multimedia technology, audio performance, and more. Notably, key performance indicators such as clarity, display resolution, and intelligence, which are of great interest to the market, are explicitly stated in this document. The release of this Standard will serve as a technical specification in the smart projector industry, facilitating standardized and high-quality development for the entire industry. At the same time, it will also drive domestic smart projector manufacturers to continuously improve their technical levels and form a technical advantage.
