What type of device uses Digital Light Processing (DLP)?

Digital Light Processing (DLP) is a technology that primarily utilizes a digital micromirror device (DMD) to project images by reflecting light off tiny mirrors. This makes it especially suitable for digital projectors, which need to create large, high-quality images for display in various settings such as classrooms, conferences, and home theaters.

DLP technology provides advantages such as high brightness and sharp image quality, which are crucial for display applications. While televisions can utilize different types of display technologies, including LED, LCD, and OLED, DLP is specifically known for its significant presence in the digital projection space. Similarly, computer monitors typically employ LCD or LED technologies, while smartphones usually use OLED or LCD screens. Thus, the use of DLP is almost exclusively associated with digital projectors, underscoring why this is the correct answer.
