LeTV TVs primarily use OLED (Organic Light-Emitting Diode) screens. This technology is favored for its high contrast ratio, deep black levels, and vibrant colors, which provide an immersive viewing experience. According to a report by Display Supply Chain Consultants (DSCC), OLED TV shipments have been growing steadily, with a significant portion being used in mid to high-end models like those produced by LeTV. The choice of OLED screens for LeTV TVs is driven by the need to offer consumers superior picture quality and a competitive edge in the market.
