the volume of…—How many raw materials are needed to produce an LCD display?

Many different raw materials are used directly or indirectly in the manufacture of an LCD display. All of them in the display we are looking at are illustrated as volumes in this animation. Based on data from Chi Mei Optoelectronics (CMO) on display modules, based on a study by the German Federal Environmental Agency (1), the resource consumption is shown as shown in the video, including indirectly used resources and upstream chains. By calculating the volume of each resource, I was able to display the resources in the video and sort them by size. (2,3,4)
