Comparison of CRT, LCD, and plasma
Parameter | CRT | LCD | Plasma | OLED |
---|---|---|---|---|
Static Contrast ratio | Over 15,000:1[1] | 150 to 6,600:1[2][3] | 3800:1[4] | "∞" "Inf:1"[5]
Unable to be calculated as black levels are zero. |
Peak Luminosity | 176 cd/m²[1] | 276-1460 cd/m²[3] | 50-200 cd/m²[1] | 100-700 cd/m² [6] |
Color depth | 24-bit per pixel resolution; offers better resolution for grayscale | 6 to 10-bit per subpixel panels;[7] smaller dot pitch, better detail[8] | 6 to 8-bit per subpixel panels; best color gamut[9][resource out of date, not impartial][10][resource out of date; source not credible/reputable] | |
Response time | Less than 1 µs[11] | 1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms[12] | Less than 1 µs; can get up to 0.001 µs[13] | |
Frame rate | 60–85 fps typically, some CRTs can go even higher (200 fps at reduced resolution[14]); internally, display refreshed at input frame rate speed |
60 fps typically, some can do 120 fps; internally, display refreshed at up to 240 Hz[15] |
60 fps typically, some can do 120 fps; internally, display refreshed at e.g. 480 or 600 Hz[16] |
|
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[17] | High altitude pressure difference may cause poor function or buzzing noises[18] | |
Flicker | Perceptible on lower refresh rates (60 Hz and below)[19] | Depends; as of 2013, most LCDs use PWM (strobing) to dim the backlight[20] | Does not normally occur due to high refresh rate.[21] | |
Size | Up to 43" | Up to 108"(2.78m)[22] | Up to 150"(3.8m)[23] | |
Energy consumption and heat generation | High[24] | Low[24] |
Varies with brightness but usually higher than LCD[25][26][27][28] | |
Maintenance | Hazardous to repair or service due to high-voltage, requires skilled convergence calibration and adjustments for geographic location changes.[29]Glass display tube is evacuated and carries risk of implosion if improperly handled. |
Risky and expensive to repair due to complexity of the display;[30] units with mercury lamps are a minor environmental hazard[31] | Screen itself cannot be repaired if the gas used to generate images leaks[32] | |
Electro-magnetic radiation emission | Can emit a small amount of X-ray radiation. | Only emits non-ionizing radiation.[33] | Emits strong radio frequency electromagnetic radiation[34] | |
Other | No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling).[35] 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.[36]Extremely bulky and heavy construction in comparison to other display technologies. Large displays would be unsuitable for wall mounting. | The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.[37] |
Screen-door effects are more noticeable than LCD when up close, or on larger sizes;[38] Risk of image retention or 'burn-in'. |
Risk of image retention or 'burn-in'.
Coloured sub-pixels may age at different rates, leading to a colour shift. Sensitive to UV light from direct sunlight. |
