Comparison of CRT, LCD, Plasma, and OLED
Further information: Comparison of display technology
Parameter | CRT | LCD | Plasma |
---|---|---|---|
Contrast | Over 15,000:1[1] | 5,000 to 10,000:1[2] | 10,000:1[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] mercury lamps make it 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 | No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling).[32] 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.[33] | The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.[34] |
Screen-door effects are more noticeable than LCD when up close, or on larger sizes;[35] |
