As a key component of laser display systems, the performance of laser display screens directly affects the quality of the final displayed image. Therefore, accurate and comprehensive testing of laser display screens is crucial. The IEC 62906-5-6 standard specifies in detail the testing methods for laser display screens, including but not limited to the optical performance of the screen (such as brightness, contrast, color uniformity), physical characteristics (such as screen size, resolution), viewing angle performance, and adaptability of the screen to laser light sources.
