(Redirected from Comparison of CRT, LCD, Plasma, and OLED)
|Static contrast ratio||Typical 200–300:1||150 to 8,100:1||Typically 1,000:1 - 3,000:1, Some models measured up to 20,333:1 ||"Between 0.0001 and 0.00001 nits" "Sony claims an OLED contrast range of 1,000,000:1. When I asked how the contrast could be so high I was told that the surface is SO black the contrast is almost infinite. If the number representing the dark end of the contrast scale is nearly zero then dividing that number into the brightest value results in a very, very high contrast ratio." (1) Pixels can reset to black nearly instantaneously, so black levels remain consistently as black as they can be.|
|Peak luminosity||176 cd/m2||200–4,000 cd/m2||50–200 cd/m2||100–700 cd/m2|
|Color depth||citation needed][||6- to 10-bit per subpixel panels; smaller dot pitch, better detail||6- to 8-bit per subpixel panels||8- to 10-bit per subpixel, with some HDR models capable of 12-bit per subpixel.|
|Response time||0.01 ms to less than 1 µs, but limited by phosphor decay time (around 5 ms)||1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms||Typically less than 0.01 ms, as low as 2 µs, but limited by phosphor decay time (around 5 ms)||Estimates varying from under 0.01 ms to as low as 1 µs.|
|Frame rate (refresh rate)||60–85 fps typically, some CRTs can go even higher (200 fps at reduced resolution);
internally, display refreshed at input frame rate speed
|60 fps typically, gaming monitors can do up to 360 fps;
internally, display refreshed at up to 360 fps
|60 fps typically, some can do 120 fps;
internally, display refreshed at e.g. 480 or 600 fps
|60 fps typically. Up to 175 fps.|
|Flicker||Perceptible on lower refresh rates (60 fps and below)||Depends; in 2013 most LCDs used PWM (strobing) to dim the backlight However, since then many flicker free LCD computer monitors were introduced.||Does not normally occur due to a high refresh rate higher than FPS||Does not normally occur at 100% brightness level. At levels below 100% flicker often occurs with frequencies between 60 and 255 Hz, since often pulse-width modulation is used to dim OLED screens.|
|Risk of image persistence or burn-in||High||Low||High||Medium|
|Energy consumption and heat generation||High||Low
||Varies with brightness but usually higher than LCD||Varies based on image brightness and color. For the majority of images it will consume 60–80% of the power of an LCD.
OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, while OLED can use more than three times as much power to display a mostly white image compared to an LCD.
|Environmental influences||Sensitive to ambient magnetic fields, which can adversely affect convergence and color purity.||Prone to malfunctions on both low (below −20 °C, −4 °F) or high (above 45 °C, 113 °F) temperatures||High altitude pressure difference may cause poor function or buzzing noises||Can have poor brightness.|
|Electro-magnetic radiation emission||Can emit a small amount of X-ray radiation.||Only emits non-ionizing radiation.||Emits strong radio frequency electromagnetic radiation||No, control circuitry may emit radio interference|
|Size||Up to 43″ (1.09 m)||Up to 120″ (3.04 m)||Up to 150″ (3.8 m) (152" experimental)||Up to 88″ (2.24 m)|
|Maintenance||Hazardous to repair or service due to high-voltage,
requires skilled convergence calibration and adjustments for geographic location changes. Glass display tube is evacuated and carries risk of implosion if improperly handled.
|Risky and expensive to repair due to complexity of the display; units with mercury CCFL backlight lamps are an environmental health hazard||Screen itself cannot be repaired if the gas used to generate images leaks|
|Other||No native resolution. Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling). 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. Extremely bulky and heavy construction in comparison to other display technologies. Large displays would be unsuitable for wall mounting. New models are no longer produced.||The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality.
Is the cheapest display technology currently produced, with some entry-level models selling for less than $100.
|Screen-door effects are more noticeable than LCD when up close, or on larger sizes. New models are no longer produced.||Colored sub-pixels may age at different rates, leading to a color shift. Sensitive to UV light from direct sunlight. Is considered the highest quality but also the most expensive display technology currently produced, with products rarely being available for less than $1200.|
