Comparison of CRT, LCD, plasma, and OLED

Parameter CRT LCD Plasma
Contrast Over 15,000:1[1] 5,000 to 10,000:1[2] 5,000,000:1[3]
Color depth 24-bit per pixel resolution; offers better resolution for grayscale 6 to 10-bit per subpixel panels;[4] smaller dot pitch, better detail[5] 6 to 8-bit per subpixel panels; best color gamut[6][7]
Response time Less than 1 µs[8] 1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms[9] Less than 1 µs; can get up to 0.001 µs[10]
Frame rate 60–85 fps typically, some CRTs can go even higher (200 fps at reduced resolution[11]);
internally, display refreshed at input frame rate speed		 60 fps typically, some can do 120 fps;
internally, display refreshed at up to 240 Hz[12]		 60 fps typically, some can do 120 fps;
internally, display refreshed at e.g. 480 or 600 Hz[13]
Environmental influences Sensitive to ambient magnetic fields, which can adversely effect convergence and color purity. Prone to malfunctions on both low (below -4 °F\-20 °C) or high (above 45 °C\113 °F) temperatures[14] High altitude pressure difference may cause poor function or buzzing noises[15]
Flicker Perceptible on lower refresh rates (60 Hz and below)[16] Depends; as of 2013, most LCDs use PWM (strobing) to dim the backlight[17] Does not normally occur due to high refresh rate.[18]
Size Up to 43" Up to 108"(2.78m)[19] Up to 150"(3.8m)[20]
Energy consumption and heat generation High[21] Low[21]
 Varies with brightness but usually higher than LCD[22][23][24][25]
Maintenance Hazardous to repair or service due to high-voltage,
requires skilled convergence calibration and adjustments for geographic location changes[26]		 Risky and expensive to repair due to complexity of the display;[27] units with mercury lamps are a minor environmental hazard[28] Screen itself cannot be repaired if the gas used to generate images leaks[29]
Electro-magnetic radiation emission Can emit a small amount of X-ray radiation. Only emits non-ionizing radiation.[30] Emits strong radio frequency electromagnetic radiation[31]
Other 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.[32] The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.[33]
Screen-door effects are more noticeable than LCD when up close, or on larger sizes;[34]
