Abstract

The invention discloses a blue light detecting method for a medical display device. The method comprises the following steps: an image generating module provides a test image with the image resolutionup to a pixel level for a medical display device; and a spectral radiation luminance meter module is used for measuring red-green-blue three-primary-color spectrum data of the medical display deviceand upper computer software analyzes the degree of blue light radiated by the medical display device according to the spectrum data. Meanwhile, the invention provides a comprehensive blue light hazardevaluation method for a medical display device with three physical indicators of a blue light hazard weighted radiance value LB, a blue light hazard efficiency value KB, V and a rhythm factor KC so as to overcome defects of blue light measurement and objective evaluation of the medical display device. Besides, the invention also provides a blue light detecting apparatus for a medical display device pixel level, thereby realizing the high-precision measurement and accurate evaluation of blue components of a pixel-level test screen of a medical display device.

Description

technical field [0001] The invention relates to a blue light detection device and method for medical displays, belonging to the technical field of medical displays. Background technique [0002] In recent years, the digitalization process of medical imaging has accelerated: on the one hand, imaging systems such as CT, MRI, ultrasound (us), and digital X-ray photography have achieved direct digitalization; The network of the information system (Hospital Information System, HIS) is connected in parallel to form the medical image storage and transmission system (Picture Archiving and Communication System, PACS). These advanced technologies make "soft film reading" possible. As a display terminal, medical monitors have become an important visualization device for doctors to perform medical image diagnosis. [0003] The luminescence of medical display screens is generally within the visible light range of 380-780nm, and the color display generally obtains color images through t...
