一种电子显示屏视觉适宜性测试装置的研制

Development of an Experimental Device for Suitability of Screen Display Brightness of Electronic Products

为测试在不同环境光照度下人眼对电子显示屏亮度的视觉适宜性,研制团队按正常人在不同光照度环境下观看电子显示屏的实际场景,研制出一种电子显示屏视觉适宜性测试装置。该装置区别于积分球的工作原理、功能、结构。正方形试验箱内壁设置可前后移动平板灯,在无极调光控制器作用下,营造出不同的环境光照度。人眼和光学测量仪器通过观察窗水平等距地测验评价电子显示屏指标,实现电子显示屏的视觉适宜性测试。测试装置的研制成功,为电子显示产品领域视觉适宜性标准研究奠定硬件基础。

In order to test the subjective suitability of the human eye to the brightness of electronic display under different ambient illuminance,the development team developed a subjective suitability test device for the electronic display according to the actual scene of normal people watching the electronic display under different illuminance environment.The device is different from the working principle,function,background and structure of the integrating sphere.The inner wall of the square test box is equipped with a flat light that can move back and forth.Under the action of the poleless dimming controller,different ambient illuminance is created.The human eye and the optical measuring instrument evaluate the electronic display through the horizontal equidistant test of the observation window,and realize the subjective suitability test of the electronic display.The successful development of the test device lays a hardware foundation for the study of the subjective suitability standard in the field of electronic display of electronic products.
