There are several scanning/raster type display technologies other than CRTs, including Plasma display panels (PDP), Digital Light Processing (DLP), and Cathode Ray Tube Rear Projection (CRT RP). While PDPs were once popular, they have largely been replaced by newer technologies like LCD and OLED displays. DLP is commonly used in projectors and some TVs, while CRT RP was popular in the late 1990s and early 2000s. While newer technologies have largely replaced scanning/raster type displays, some are still used in niche applications such as projectors and large-screen displays.
