TV display demand comes from two segments: first-time purchases and the replacement cycle. First-time purchases come from emerging countries and regions such as India, South America, and Africa, where, as income improves and households grow, the demand for TV displays increases. On the other hand, the replacement cycle involves replacing old TVs, which were purchased several years ago, with newer, better, and in many cases, bigger TVs. The interval between the replacement of old TVs and the purchase of new TVs is jointly referred to as the replacement cycle in the TV display industry. In the past 20 years, both first-time purchases and the replacement cycle drove TV display shipments upward, increasing from less than 10 million units per year to more than 250 million units per year.
