Indium Tin Oxide film, commonly known as ITO, is a vital material in modern electronics. This transparent conductive oxide combines indium oxide with tin oxide, creating a thin film that excels in both electrical conductivity and optical transparency. ITO is typically deposited on substrates like glass or plastic using methods such as sputtering or evaporation. Its key properties include high transparency to visible light, low electrical resistance, and strong infrared reflectivity. These traits make ITO indispensable for touchscreens, where it forms electrodes that detect user input without obscuring the display. It is also widely used in liquid crystal displays, OLED panels, solar cells, and energy-efficient smart windows. Despite its advantages, ITO faces challenges due to the scarcity and cost of indium, brittleness limiting flexibility, and energy-intensive manufacturing processes. Research focuses on alternatives like graphene, silver nanowires, or conductive polymers, but ITO remains dominant due to its proven reliability and performance. As technology evolves, ITO continues to enable innovations in transparent electronics, maintaining its role as a cornerstone material in the industry.
