[The international standard for raster scanning laser displays led by China is officially released] On November 10, we learned from the National Standards Committee that the International Electrotechnical Commission (IEC) recently officially released the international standard "Laser Display Part 5-8: Scanning Characteristics Test Method for Raster Scanning Laser Displays". The standard is jointly developed by Chinese experts as project leaders and experts from Belgium, the United States, Japan and other countries. Raster scanning is one of the main technical routes for laser display. Common products include micro laser projectors, AR/VR displays (augmented reality displays and virtual reality displays), etc. Raster scanning is like using a very thin "laser paintbrush" to draw on the screen: through a small mirror that swings quickly, the laser beam is controlled to move up, down, left, and right to scan out the complete picture. This standard stipulates the test conditions and test methods for the main characteristics of raster scanning laser display devices such as scanning linearity, scanning repeatability and waviness, as well as the reporting form of test results. It provides reliable technical support for product development, manufacturing and quality evaluation, and is conducive to improving the comparability of test results between different products and different testing institutions. Raster scanning laser display is a key pixel engine that supports the expansion of human-computer interaction applications such as AR/VR and vehicle-mounted light fields. China has taken the lead in condensing the results of independent technological practices into international standards, which has a positive effect on the future development of the laser display industry and is an important step in the development of China's core laser display technology field.
