Detailed Description

You can’t have touchscreens without indium. The most common use of indium is for indium-tin oxide, a transparent conducting oxide used in almost every flat-panel display and touchscreen. A thin coating of indium-tin oxide on the display surface transforms incoming electrical data into an optical form. Indium is a critical material for display technology because there are few substitutes. Also, as a zinc byproduct, the supply of indium is dependent on the zinc industry. More than one-half of the world's total is produced in China. The United States is 100% import reliant for its supply of indium.
