large-screen television technology developed rapidly in the late 1990s and 2000s. various thin screen technologies are being developed, but only the liquid crystal display (lcd), plasma display (pdp) and digital light processing (dlp) have been released on the public market. a video display that uses large-screen television technology is called a jumbotron. these technologies have almost completely displaced cathode ray tubes (crt) in television sales, due to the necessary bulkiness of cathode ray tubes. however, recently released technologies like organic light-emitting diode (oled) and not-yet released technologies like surface-conduction electron-emitter display (sed) or field emission display (fed) are making their way to replace the first flat screen technologies in picture quality. the diagonal screen size of a crt television is limited to about 40 inches because of the size requirements of the cathode ray tube, which fires three beams of electrons onto the screen, creating a viewable image. a larger screen size requires a longer tube, making a crt television with a large screen (50 to 80 inches) unrealistic because of size. the aforementioned technologies can produce large-screen televisions that are much thinner.
