Parameter CRT LCD Plasma
Contrast Over 15,000:1[1]
Color depth 68 × 109[dubious ][2][3]
Response time 1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms[4]
Frame rate 60–85 fps typically, some CRTs can go even higher ("200 fps at reduced resolution"[5]);
internally, display refreshed at input frame rate speed
60 fps typically, some can do 120 fps;
internally, display refreshed at eg. 480 or 600 Hz[6]
Environmental influences High altitude pressure difference may cause poor function or buzzing noises[7]
Flicker Depends; as of 2013, most Plasmas use PWM (strobing) to dim the backlight[8]
Size Up to 150"(3.8m)[9]
Energy consumption and heat generation High[10] Low[10]
Varies with brightness but usually higher than LCD[11][12][13][14]
Maintenance Hazardous to repair or service due to high-voltage,
requires skilled convergence calibration and adjustments for geographic location changes[15]
Electro-magnetic radiation emission Emits strong radio-frequency electromagnetic radiation[16]
Other No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling).[17] Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays.[18] The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.[19]
Screen-door effects are more noticeable than LCD when up close, or on larger sizes;[20]
